When Is a ClearVue 350 Assembly Actually Paired with 550 in FDA Language, and When Is 650 Only Grouped Later in the 850 510(k)?

In procurement and ISO discussions, adjacent ClearVue model numbers are often treated as the same hardware in a restyled enclosure. Aftermarket dumps reinforce that assumption by marketing parts under blanket headings such as 'ClearVue 350/550/650/850'. The FDA 510(k) and listing records show a different split ^{1 2}.

Diagnostic ultrasound consoles are Class II devices under product code IYN (21 CFR 892.1550) and IYO (21 CFR 892.1560). Transducers are ITX (21 CFR 892.1570) ¹. A ClearVue PSU, motherboard, control panel, or TI/acquisition assembly is a system-level subassembly, not an ITX transducer event, unless the ticket is the 3D9-3v probe itself. The ClearVue consoles used in this article sit on two named Traditional IYN 510(k) rows:

• FDA 510(k) K120321 (decision date 17 February 2012): Traditional 510(k), product code IYN, device_name CLEARVUE 350/550 DIAGNOSTIC ULTRASOUND SYSTEM ². The summary names Philips HD11 (K043535) as predicate and states that the 550 model has more complete features than the 350, with an articulating display arm versus a 350 tilt-swivel mount ². Combined 350/550 clearance is not a pin-for-pin SKU license and does not name 650 or 850.
• FDA 510(k) K153480 (decision date 16 December 2015): Traditional 510(k), product code IYN, device_name ClearVue850 Diagnostic Ultrasound System ². Predicates are ClearVue 350/550 (K120321) and EPIQ (K132304) for L12-5 and D2cwc. Comparison text groups ClearVue 350/550/650 under K120321 and uses substantial-equivalence language. That grouping is not a catalog identity and is not a license into EPIQ ACQ/AIM.
• Quoted 650 device_name is NOT_FOUND: An openFDA 510(k) search for device_name "ClearVue 650" returned NOT_FOUND ². Absence of a quoted 650 device_name is not end-of-support and is not proof that 650 hardware equals 350 or 850.
• Registration listing still names 650 — and 580: openFDA registrationlisting (last_updated 2026-08-31) returned 12 records for proprietary_name ClearVue 650 whose arrays include ClearVue 350, 550, 580, 650, and 850 Diagnostic Ultrasound System ². Listing is not a 510(k) device_name. ClearVue 580 has no photographed SKU in the current catalog and is not in Rongtao Philips coverage; do not invent a 580 board matrix from the listing string.

Regulatory grouping in a 510(k) summary is a marketing-authorization comparison. It is not an engineering declaration that power converters, host modules, or acquisition cards interchange across ClearVue tiers ². Rongtao's published Philips coverage lists CV350, CV650, and CV850 ⁵. ClearVue 550 is the FDA-named pair of 350 on K120321; it is not a Rongtao coverage expansion and has zero catalog SKUs this snapshot.

Which ClearVue Board Domain Does My Symptom Point To? (Table 1: Symptom-to-Board Routing Matrix)

When a ClearVue cart fails, a dark display is often blamed on the host module, and a missing probe channel is often blamed on the transducer. Use Table 1 to route the symptom to a verified assembly family, then match the etched number. Generic rails-down physics belong on the cart PSU parent; this page only adds the 350/650/850 identity collisions ^{5 6}.

Why Catalog 453561441344 Is Not a Silent 650 PC-Module License Even Though philipsusparts Prints It on Both Parts Lists

A common ISO and hospital sourcing trap is the ClearVue host computer module. philipsusparts lists 453561441344 as 'PC Module' on both the ClearVue 350/550 parts page and the ClearVue 650 parts page, and prints adjacent suffixes 453561441341 / 441342 / 441343 as PC Module on the 350/550 dump ⁸.

Rongtao catalog 453561441344 is photographed and labeled CV350 Motherboard ⁵. A migrated archive title documents ClearVue 650 main board 453561914072 ⁶. Those two strings are not a proven silent swap. Dual-page dumps and adjacent digits are not a license to install a CV350-labeled module in a 650 cart:

• Catalog versus aftermarket label: Catalog identity is CV350 motherboard 453561441344. philipsusparts dual-listing of the same string on the 650 dump is a collision to resolve with the etched plate, not a Rongtao interchange table.
• Legacy 650 main-board title: 453561914072 is a migrated product note, not a current catalog SKU and not a documented replacement for 441344.
• Software options: Clinical features locked by software must be procured through official OEM licensing. Rongtao does not generate option keys, and a motherboard swap is not a substitute for a license string.

When a ClearVue 650 has power present but no scanning UI, do not order CV350 motherboard 453561441344 from the dual listing. First follow the host/HDD versus CMOS boot path ⁶.

Why 453561451365 Is a CV650 Power Board, Not a 350/550/650/850 Regulator, and Why MISP1903 Is Not Catalog AC 453561749152 or 453561638982

Cart power supplies see continuous duty and thermal load, so they generate a high share of no-power tickets. ClearVue power identity is also where current search results are most misleading ⁷.

A 2026-09-05 search for 'philips clearvue 850 power supply' produced an AI Overview asserting 100-240 VAC / 50/60 Hz / 400 VA and treating 453561451365 as a regulator shared across 350/550/650/850, with organic results pointing to Made-in-China copy for that PN and DOTmed broker assembly MISP1903 ^{7 8}. Those electrical figures and the broker string are not Rongtao catalog identities.

Verified catalog and dump labels do not support a four-model PSU ⁵:

• CV350 AC 453561749152: Catalog 453561749152 is labeled 'AC Power Supply 453561749152', model CV350 ⁵. It is the only exact ClearVue inventory PN in the 2026-09-05 snapshot (90-day warranty field). Stock turns; confirm live catalog or quote.
• CV650 AC 453561638982: Catalog 453561638982 is labeled 'AC 453561638982', model CV650 ⁵. philipsusparts prints the same 638982 (and 638983) as AC DC Converter on both the 350/550 dump and the 650 dump. Dual listing is not a silent 350 license and is not, by itself, a lab proof of physical fit. Match the etched converter number.
• CV650 power board 453561451365: Catalog 453561451365 is labeled 'Power Board 453561451365', model CV650 — the leftover confirmation row on the published cart PSU parent ^{5 6}. philipsusparts 650 and 350/550 dumps list 451361–451364 as Power Regulator Module, not 451365. Adjacent digits are not catalog identity.
• Broker MISP1903: A commercial listing tag, not a Philips OEM assembly in Rongtao's catalog ⁸. Do not republish 400 VA or four-model sharing as a catalog row.

When a ClearVue cart is rails-down or boot-loops under load, open the lower compartment only if you are qualified to do so, photograph the OEM rating plate, and match the stamped 12-digit number (453561749152 versus 453561638982 versus 453561451365) ⁵. Do not order from an AI Overview four-model title.

How to Tell 3-Port TI 453561486821 from 4-Port TI 453561494512 Before Trusting an eBay 4-Port Title

The transducer interface (TI) / acquisition module routes probe connections into the console front end ^{1 5}. When probes fail to initialize or drop channels, the TI is a candidate — after the probe itself and the connector are cleared, and after the 3D9-3v recall gate on an 850 volume probe ⁶.

Secondary listings confuse the two photographed ClearVue TI SKUs. eBay item 198109720251 titles 453561486821 as a ClearVue 350/550/650 4-port acquisition module ⁸. That title contradicts both the catalog photograph and the philipsusparts 3-port label:

• Catalog 453561486821 (model CV): 453561486821 is photographed as the TI for model CV. The catalog photograph shows three transducer receptacles. philipsusparts 350/550 dump labels it Acquisition Module, 3-Port ^{5 8}.
• Catalog 453561494512 (model CV650 850): 453561494512 is photographed as the TI for models CV650 850. The catalog photograph shows four receptacles. philipsusparts 650 dump labels it Acquisition Module, 4-Port ^{5 8}.
• The 350/550 dump is not 3-port-only: philipsusparts 350/550 also lists 453561494511 and 453561494512 as 4-Port. A 350/550 ticket can still be a 4-port cage. Count the receptacles on the console and match the etched number; do not assume every 350 is 486821 or that every 4-port board belongs in a 650/850.

Before ordering a TI, count the physical probe ports on the front panel and photograph the etched 12-digit number ⁵. Marketplace titles and invoice text are not catalog identity.

If the 850 Volume Probe Housing Is Separating, Why Z-2517-2023 Is Not a Reason to Order 453561494512

A mechanical transducer defect can mimic a console acquisition failure. On ClearVue 850, a 3D/4D stall with a 3D9-3v transducer is not automatic grounds to order 453561494512 ^{3 5}.

A bounded scan of 527 ultrasound-code (ITX/IYN/IYO) recall rows in the FDA recall extract (export 2026-07-24; 58,785 rows) plus openFDA found a named exception gate, not a board census: Class II Completed Z-2517-2023 (Event ID 92761, initiated 30 June 2023, posted 6 September 2023) ³:

• Product and class: Product code ITX (21 CFR 892.1570). Product: 3D9-3v Transducer, accessory to Philips Ultrasound Systems — not the console TI, PSU, or motherboard ³.
• Official reason: The transducer consists of two parts that are bonded together that may come apart due to a chassis bonding issue, which may pose a risk of tissue damage and electric shock if built-in electrical-safety measures also fail ³. The recall-row root-cause field is Process control.
• Host list: EPIQ Elite; Affiniti 30, 50, and 70; ClearVue 850; HD15; iU22; and Compact 5000 ³.
• Later 3D9-3v actions: Z-2048-2025 and Z-2347-2025 also name the 3D9-3v and are already documented on the 4D parent. They are not a reason to order 453561494512 as a recall correction.

The same 527-row scan returned zero recall records naming ClearVue hardware PNs 453561749152, 453561441344, 453561638982, 453561451365, 453561486821, 453561494512, 453561775033, 453561914072, or 453561814481 ³. Quoted openFDA MAUDE searches for those board model numbers returned NOT_FOUND ⁴. Passive-surveillance emptiness is not incidence, not a proof of zero field events, and not comparative safety.

If a ClearVue 850 3D9-3v housing is separating, treat it as a probe ticket. Replacing console board 453561494512 does not execute the recall correction. Route the transducer to the manufacturer field action or to ultrasound probe repair, as detailed on the 4D motor board versus volume probe path ^{3 6}. Do not return a separating housing to clinical use.

Where HD11 K043535 Tickets Go, and Why Substantial Equivalence Is Not a Board Swap into AIM/ACB

Because K120321 names Philips HD11 (K043535) as predicate, some tickets treat ClearVue as an HD11 card-cage donor ². The 2026-09-05 AI Overview for 'philips clearvue 650 board repair' also cites Rongtao's Philips brand page with HD11 main-board copy ⁷. Substantial equivalence is not a board swap into AIM/ACB.

Keep platform boundaries ^{5 6}:

• Philips HD11 / HD15 / HD11 XE: Dedicated AIM/ACB/FE path, including catalog 453561182933 and 453561197145. Those boards are not ClearVue SKUs. Send HD tickets to the Philips HD11/HD15 board symptom decision path. EnVisor HD7 is already a leave-this-page gate there. HD5 remains a leftover, not this article.
• Philips CX50: Compact chassis with catalog motherboard 453561239048 and TI 453561473251. Send compact tickets to the Philips CX50 board path. Token CV does not match CX50 on live model pages.
• Philips EPIQ / Affiniti / iU22 / iE33: Catalog ACQ-A 453561704246 and EPIQ PSU 453561879752 are not ClearVue parts. K153480 cites EPIQ K132304 for L12-5 and D2cwc transducers, not internal ACQ. YouTube EPIQ PSU shorts on the 850 power query are pollution. Send those tickets to the Philips EPIQ/iU22/iE33 board path.
• Software / remote service: The cybersecurity pillar names ClearVue among software-patch fleets. Patch, segmentation, and remote-service tickets belong on legacy ultrasound cybersecurity patch versus isolate versus replace, not on a PSU or motherboard order.

CV350 Control Panel 453561775033A versus 650 Assembly 453561645392 versus Legacy Monitors 453561962241

Control-panel and display tickets (keys, TGC, trackball, backlight) need the same model split as power and host ^{5 6}.

Verified labels, not assumed bezels ^{5 8}:

• CV350 control panel: Catalog 453561775033A is labeled 'Control Panel 453561775033A', model CV350 ⁵.
• Aftermarket 650 panel 453561645392: philipsusparts 650 dump lists Control Panel Assembly 453561645392 ⁸. That string is not a Rongtao catalog SKU. Dual marketing of 775033A into a 650 frame is not documented here.
• Display: K120321 distinguishes a 350 tilt-swivel mount from a 550 articulating arm ². Migrated CV350 monitor titles are 453561962241, 453561962242, and 453561962662 ⁶. philipsusparts 650 dump lists LCD 453561625142 / 453561625143. Those are display-lane cross-links to the control panel, touch, trackball and display path, not a second monitor article and not a 17-versus-19-inch interchange table.

ClearVue Part Number Collision and Sourcing Matrix (Table 2)

Table 2 is the extractable collision matrix: catalog label versus aftermarket dump versus AI Overview identity. Use it to audit quotes before releasing a purchase order. It is not a pin-for-pin compatibility license.

Why the Live CV350 Model-Page Stock Table Is Currently Exact, and Why CV650 Still Must Not Inherit 350 Inventory

Live model taxonomy is useful for navigation and a trap if copied as a parts list. On /models/philips-cv350, token CV350 currently matches exactly one inventory row: 453561749152 (AC power supply, model CV350, 90-day warranty field) ⁵. That mapping is exact in this snapshot. Stock turns.

/models/philips-cv650 currently has zero inventory rows ⁵. Catalog still photographs CV650 AC 453561638982, power board 453561451365, and CV650/850 TI 453561494512. /models/philips-cv650-850 also attaches those CV650 catalog SKUs because the page token includes CV650. That substring include is taxonomy, not an 850 PSU identity and not a reason to ship 749152 into a 650 or 850 cage.

Token CV on /models/philips-cv indexes catalog TI 453561486821 and does not attach CX50 or iU22 stock ⁵. The ranking legacy note /blog/philips-clearvue-650-machine is mislabeled Probe / Transducer with PN P00908P1 — cite it as a SKU-dump collision, not current catalog identity ^{6 7}. Confirm availability through live catalog or quote.

Where Rongtao Fits, and Where It Does Not — Including Quote-Ready Photos

An independent service partner should say where it can help and where it cannot. There are zero Rongtao photo ClearVue teardowns in the current case library, so this page does not publish a ClearVue success rate ⁵.

Where Rongtao Medical fits:

• Identified-board repair: Component-level repair of extracted assemblies after the etched label is matched — including catalog CV350 AC 453561749152, motherboard 453561441344, panel 453561775033A, CV650 AC 453561638982, CV650 power board 453561451365, CV TI 453561486821, and CV650/850 TI 453561494512.
• 48-hour real-machine test: Repaired boards run 48 hours inside an actual ultrasound, with photo/video evidence where applicable — not bench-only.
• Catalog photos versus stock: 254 photo-backed SKUs this snapshot. Catalog photographs are not guaranteed current inventory. Confirm availability at quote.
• Commercial terms: Standard board-repair turnaround is 5–8 business days, typically 90-day warranty, confirmed per item. Acme 180-day copy and AI Overview 90–180 day bands are not Rongtao offers.

Where Rongtao Medical does not fit:

• Not an OEM representative: Independent service and parts. Philips, GE, Siemens, and other OEM names identify equipment coverage only — not authorization or endorsement.
• No option keys or recall software: We do not generate Philips software option keys and do not apply OEM field-safety software. Locked clinical features and recall software corrections stay on official channels.
• No unqualified energized work: This page does not instruct unqualified readers to probe live power supplies, bypass interlocks, or reseat acquisition modules under power.
• No 550 or 580 catalog matrix: 550 is an FDA device_name pair on K120321; 580 appears in listing arrays. Neither has photographed SKUs in the current catalog or published Philips coverage list.

Quote-Ready Checklist: What to Provide for an Expedited Quote

To quote without using the legacy 650 machine page or a four-model dump, send:

1. Rating plate: Photograph of the rear manufacturer plate showing exact model (ClearVue 350, 550, 650, or 850), serial number, and electrical rating.
2. Both sides of the suspect assembly: Photographs capturing the 12-digit Philips part number (453561…), revision, and barcodes.
3. Symptom: Rails down, black LCD with fans on, specific probe unrecognized, 3D9-3v housing separation, or network/DICOM failure — plus any on-screen dialog.
4. Logistics: Quantity, destination country, and whether the request is repair of the existing board or a tested replacement.

Submit the packet through the contact and quote portal. Brand navigation: Philips ultrasound parts and models.

Frequently Asked Questions (FAQs)

Q1: The 850 power AI Overview says my ClearVue uses regulator 453561451365 or MISP1903. Should I order those instead of matching the etched label?
Answer: No. Catalog 453561451365 is the CV650 power board, not an AC mains supply and not a four-model regulator ⁵. CV350 AC is 453561749152; CV650 AC is 453561638982 ⁵. MISP1903 is a broker string. Photograph the physical 12-digit label.

Q2: K153480 comparison text groups ClearVue 850 with ClearVue (K120321). Can I fit CV350 motherboard 453561441344 in a 650 or 850?
Answer: No. Substantial-equivalence language is not a pin-for-pin SKU license ². Catalog 453561441344 is labeled CV350 ⁵. philipsusparts printing 441344 on the 650 dump is the collision this page exists to stop. Legacy 650 main-board title 453561914072 is not a documented swap.

Q3: ClearVue 650 boots with fans and LEDs on but a black screen. Is that 453561451365, 453561441344, or the LCD path?
Answer: Do not order a motherboard from the dual listing first. If a rear video output exists, test external video. If external video appears, the host and PSU are less likely; send the display path to the control-panel parent. If power is present and the scanning UI never appears, follow the host/HDD versus CMOS boot path. Catalog 451365 is a CV650 power board, not a universal black-screen diagnosis.

Q4: Probes are not recognized. Is that 3-port 453561486821, 4-port 453561494512, or Z-2517-2023?
Answer: Count the receptacles and read the etched TI number. Catalog photos show three ports on 453561486821 and four on 453561494512 ⁵. If the probe is a 3D9-3v with a separating housing on an 850 (or another listed host), that is Z-2517-2023 — a probe chassis-bonding action, not a TI census ³.

Q5: What photos are required for a ClearVue quote without using the legacy 650 machine page?
Answer: Send (1) the rear rating plate with model and serial; (2) both sides of the suspect PCB showing the 12-digit 453561… number; (3) the symptom, including any on-screen code or a 3D9-3v housing photo if relevant; and (4) quantity and destination. Use /contact. Do not treat /blog/philips-clearvue-650-machine or a four-model marketplace dump as the order identity.
