When Does FDA Language Name HD11, HD15, or HD7, and Why Is Named HD5 510(k) Emptiness Not a License to Borrow Those K-Numbers?

In clinical engineering and multi-vendor healthcare technology management (HTM), sourcing replacement ultrasound assemblies frequently begins with regulatory database cross-referencing. When service managers encounter an unbootable or malfunctioning Philips HD5 console, search queries often return references to adjacent Philips 'HD' family systems—specifically the HD11, HD15, and HD7. This leads to an immediate procurement risk: assuming that because these systems share an 'HD' prefix, their internal processing engines, motherboards, and power distribution modules must share identical hardware architecture and FDA clearance lineages.

A fielded openFDA 510(k) search (last_updated 2026-09-07) returns a bounded fact: explicit device_name searches for HD5 under diagnostic ultrasound product codes return exactly zero records (n=0) ². Whether querying under product code IYN (System, Imaging, Pulsed Doppler, Ultrasonic; 21 CFR 892.1550), IYO (System, Imaging, Pulsed Echo, Ultrasonic; 21 CFR 892.1560), or ITX (Transducer, Ultrasonic, Diagnostic; 21 CFR 892.1570) ¹, no standalone premarket notification carries the explicit device name HD5 or Philips HD5.

By contrast, adjacent Philips diagnostic systems carry extensive, documented 510(k) clearances. The Philips HD11 holds two distinct clearances: K043535 (cleared 2005-01-06, Traditional, primary IYN, subsequent ITX/IYO) and K062247 (cleared 2006-08-18, Special, primary IYN, subsequent ITX/IYO) ^{2 3}. The Philips HD15 is cleared under K081661 (cleared 2008-06-24, Traditional, primary IYN, subsequent ITX/IYO) ⁴. The Philips HD7 is cleared under K080548 (cleared 2008-03-27, Traditional, primary IYN, subsequent ITX/IYO; preserving the official FDA applicant spelling Phillips Medical Systems) ⁵. Furthermore, multi-system clearances such as K201012 (cleared 2020-05-01, Special, primary IYN) name current platforms including the EPIQ, Affiniti, CX50, Sparq, and Lumify, but make zero reference to the HD5 ⁶.

Named 510(k) emptiness does not mean the HD5 cart is mythical. Catalog photography, leftover HD5 notes, MedWrench threads, and Rongtao's documented Philips coverage string on the Philips brand page all treat HD5 as a real economy cart ^{9 10}. The US 510(k) device_name field simply does not use HD5. For a biomedical service organization, that boundary is operational: engineers cannot point to K043535, K062247, K081661, or K080548 as justification to swap HD11/HD15/HD7 parts onto an HD5.

As documented in our Philips HD11/HD15 Board Decision Path, those carts use 45356-prefix assemblies, including catalog HD11 Host PC 453561674461 and HD15 Host PC 453561317224. The Philips HD5 photographed SKU uses a 45411-prefix host PC. The prefix split is a matching clue, not a pin map. Do not order an HD11 or HD15 PC into an HD5 ticket, and do not reprint that family's PSU/ACB/AIM/FE matrix here. For brand-wide routing, start from the Philips board-level symptoms hub.

Which HD5 Board Domain Does My Symptom Point to After a Known-Good Probe, and When Is Catalog 454110649321 a Host-PC Ticket Rather Than a Front-End Order?

Effective troubleshooting of an unresponsive or malfunctioning Philips HD5 requires isolating the failure to one of three primary hardware domains: (1) the Power Distribution Subsystem, (2) the Host PC & Processing Subsystem, or (3) the Front-End Acoustic & Beamforming Subsystem. Misdiagnosing an acoustic artifact as a computer crash—or vice versa—leads to expensive part orders and unnecessary cart downtime.

The initial gate for any image-quality defect or transducer error is known-good probe verification. Probe, cable, and connector faults can mimic a beamformer ticket. If an acoustic shadow, missing scan lines, or a probe-not-recognized error occurs, connect a known-good probe on the active port and test the suspect probe on alternate ports. Only when the fault persists across known-good probes and ports should the ticket move to a console board.

The table below outlines the operational symptoms observed on Philips HD5 carts and defines the exact board-level triage path:

As highlighted in the matrix, when an HD5 cart exhibits a logo hang or failure to launch the scanning application, the ticket isolates to the host computing architecture. Clinical engineers must not mistake this for a front-end beamformer fault or an acquisition board failure. This is a host-PC ticket that centers squarely on the PC motherboard and its associated storage media.

Why Is Catalog HD5 PC 454110649321 Not Leftover 454119653661, Leftover 454110658301, or HD11 PC 453561674461?

Once a boot failure or video processing fault is isolated to the host computer, technicians face a fragmented parts marketplace characterized by confusing part numbers, combined e-commerce listings, and legacy product notes. Understanding the precise relationship between verified catalog hardware and aftermarket leftover strings is essential to avoid procurement errors.

In Rongtao Medical's verified parts catalog, exactly one HD5 assembly is photo-documented: Philips HD5 PC Motherboard 454110649321 (id hd5-pc-motherboard-454110649321, model HD5, partNumber 454110649321) ⁹. That photographed SKU has 0 inventory rows this snapshot; stock turns, and a catalog photo is not a stock guarantee. Catalog photos do not map every bus on the board.

However, a search across aftermarket parts listings and historical blog archives reveals several colliding part numbers:

• Leftover PC Main Board 454119653661: Documented in leftover notes (philips-hd5-pc-main-board-454119653661) and ranking on companion queries. The leftover title calls it an HD5 PC Main Board. It is not photographed in the current catalog. Do not treat the leftover title, or a concatenated marketplace string, as a silent swap for 454110649321.
• DOTmed concatenated listing 454110649321-454119653661: A live marketplace listing (DOTmed #5238753) strings both numbers together in one title ¹¹. Combined shopping titles are not pin-for-pin SKU evidence. Match the physical silk screen.
• Leftover Assy 454110658301 and 454110647851: Leftover notes (philips-hd5-454110658301, philips-hd5-454110647851) use Assy titles. They are not the catalog PC photo. Do not assign a catalog board class from those leftover titles, and do not order them to resolve a host boot freeze.
• HD11 / HD15 45356-prefix host PCs: Catalog HD11 PC (453561674461) and HD15 PC (453561317224) belong on the HD11/HD15 family path. The 45356 versus 45411 prefix is a matching clue, not a pin map.
• CX50 compact motherboard 453561239048: The CX50 portable uses catalog motherboard 453561239048, as detailed in the Philips CX50 Decision Path. Different cabinet and PN; not an HD5 swap.

The comparison matrix below clarifies the physical identity, origin, and triage status of these colliding part numbers:

If the Cart Hangs on a Logo or Never Loads Scanning Software, Why Is That the Host Parent After Matching Rather Than a Leftover Assy Order?

When an HD5 console powers on and spins its chassis fans but remains stuck on the boot logo, it is easy to order a leftover assembly immediately. A logo hang is still a host-versus-disk ticket after the etched PC suffix is matched, not proof that leftover Assy 454110658301 or 454110647851 is the missing part.

Use the dedicated host/HDD parent rather than reprinting its matrix here. Ultrasound Will Not Boot: Hard Drive vs Motherboard Diagnosis already lists catalog HD5 PC 454110649321 as a host-family row ¹²:

1. Match the etched PC suffix first: Confirm catalog 454110649321 versus leftover 454119653661 before ordering anything. Leftover Assy titles will not resolve a logo hang.
2. Then use the host/HDD parent: Logo-stuck and no-OS tickets on a matched HD5 PC belong on Ultrasound Will Not Boot: Hard Drive vs Motherboard, which already lists this catalog PC as a host-family row ¹². Do not reprint that CMOS/disk matrix here.
3. Do not skip the split: A dead disk, exhausted CMOS cell, or corrupted image can mimic a dead motherboard. Ordering leftover Assy 454110658301 or 454110647851 does not perform that isolation.

Ordering leftover Assy 454110658301 or 454110647851 does not isolate a disk fault, a CMOS fault, or a corrupted operating-system image. Match the etched number on Catalog PC Motherboard 454110649321, then follow the Host/HDD Boot Failure Guide before issuing purchase orders.

When Must I Refuse Z-2517-2023, Z-1842-2020, or Z-0987-2007 as HD5 Board Condemnations?

When clinical engineering departments audit their equipment fleets or investigate repeated error codes, regulatory recall notices frequently surface in compliance databases. Inexperienced technicians or third-party service providers often misapply recall actions across unrelated equipment models, leading to unnecessary equipment decommissioning or erroneous part replacement.

A prime example is FDA Class 2 Recall Z-2517-2023 (Class II Completed, event ID 92761, initiated 2023-06-30, posted 2023-09-06) ⁷. This recall concerns the 3D9-3v curved array transducer. The official product text names host systems EPIQ Elite, Affiniti 30, Affiniti 50, Affiniti 70, ClearVue 850, HD15, iU22, and Compact 5000. The Philips HD5 is not named on that host list. Associated 510(k) numbers on the recall record are not an HD5 SKU license and are not republished here as serial or quantity dumps.

Similarly, Recall Z-1842-2020 (Class II Terminated, event ID 84902, initiated 2019-08-30) covers the S7-3t transesophageal transducer on iE33 and HD11 consoles. Recall Z-0987-2007 (Terminated, initiated 2007-04-25, posted 2007-07-03, product code IYN) names the HD11XE Diagnostic Ultrasound System. None of these notices applies to the Philips HD5 console or its photographed PC motherboard ⁷.

Quoted openFDA MAUDE model_number searches (last_updated 2026-09-08) for 454110649321, 454119653661, 454110658301, and 454110647851 returned NOT_FOUND ⁸. That emptiness is not a failure rate, not a recall census, and not proof the boards never fail. Recalled 3D9-3v / S7-3t / HD11XE actions stay on their named hosts. Discard unquoted 'HD 5' homonyms and AGFA CR HD5 detector listings; do not publish those rows as HD5 ultrasound events.

Why the Ranking Philips HD5 Model Page Is a Taxonomy Hub, Not a Parts List

When searching for 'philips hd5 board repair' on Google, the number one organic search result is frequently Rongtao Medical's own model page, /models/philips-hd5, which is also directly cited by Google AI Overviews ¹¹. To a biomedical engineer seeking an immediate schematic, troubleshooting tree, or complete replacement catalog, landing on this page can cause confusion unless its architectural role is understood.

The route /models/philips-hd5 is a model hub built because the parts catalog documents Philips HD5 PC Motherboard 454110649321. It currently attaches exactly one photo-backed SKU. It is not an exhaustive multi-board parts catalog, an OEM service manual, or a component repair tree. Documented Philips coverage on the Philips brand page lists HD5; do not expand that string to HD3, HD7, Envisor, or Sparq ¹⁰.

As of 16 September 2026, /models/philips-hd5 ranked first on the family-repair query and was cited in the AI Overview ¹¹. That ranking does not make the hub a parts list. Competing results are leftover PC notes, unanswered forums, a gated overview, and wrong-device consumer pages. This report supplies the missing decision table: match the etched suffix, isolate leftover 454119653661, refuse borrowed HD11/HD15/HD7/EPIQ K-numbers, and hand a labeled RFQ to qualified repair or tested replacement.

Where Consumer HTB5520, TV SSB 313926865385, iFixit HD3, and EPIQ 5 DS SERP Pollution Go

A significant hazard in sourcing medical equipment repair online is search engine pollution resulting from brand homonyms and consumer product indexing. On queries related to Philips HD5 board repair, search engines frequently index irrelevant consumer and high-end platform results that must be ruthlessly discarded:

Consumer Home-Theater Board Pollution: Search results frequently display forum threads titled 'Philips HTB5520/94 logic board repair help needed' ¹¹. The Philips HTB5520 is a consumer 5.1-channel Blu-ray home theater system. It shares branding and partial character tokens with the HD5, but has zero medical or electronic overlap. Clinical engineers must ignore all HTB5520 forum threads.

Consumer Television SSB Board Replacement: YouTube video results index tutorials such as 'Easy Philips 313926865385 SSB / Main Boards Replacement' ¹¹. In consumer electronics, 'SSB' stands for Small Signal Board (the main logic board of a consumer television). Attempting to apply television capacitor replacement guides or consumer board baking techniques to a clinical diagnostic ultrasound console violates basic biomedical quality standards and creates serious fire and electrical shock hazards.

iFixit Philips HD3 DIY Guides: Community repair portals feature teardown wikis for the Philips HD3 ¹¹. The HD3 is an earlier, distinct compact ultrasound platform. Furthermore, Rongtao Medical's documented Philips coverage explicitly excludes the HD3 ¹⁰. Generic DIY wiki advice encouraging untrained personnel to dismantle ultrasound consoles without calibrated electrostatic discharge (ESD) protection or safety testing must be firmly rejected.

OEM EPIQ 5 DS Refurbished Listings: Commercial search results on companion part number queries frequently return OEM listings for the EPIQ 5 DS Refurbished Ultrasound Machine ¹¹. The EPIQ 5 is a premium cart platform cleared under K201012 ⁶. It belongs on our specialized Philips EPIQ / iU22 / iE33 Decision Path. EPIQ modules cannot be adapted to the HD5.

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

To ensure transparent B2B collaboration with hospital HTM departments, independent service organizations (ISOs), and medical equipment distributors, Rongtao Medical clearly delineates its commercial capabilities and operational boundaries for Philips HD5 equipment:

Where Rongtao Fits:

• Component-level motherboard repair: Qualified troubleshooting and repair for verified Philips HD5 PC Motherboards (PN 454110649321) after the etched suffix is matched. Do not treat leftover 454119653661 as a silent catalog revision.
• 48-Hour Real-Machine Testing: Every repaired or refurbished circuit board undergoes a mandatory 48-hour burn-in and functional evaluation inside an actual ultrasound console—not simple static bench testing.
• Standardized B2B Turnaround & Warranty: Standard board-repair turnaround is typically 5 to 8 business days from facility receipt. All repairs and tested replacement parts include a typically 90-day warranty, with extended plans available upon request and confirmed per item.
• Tested replacement modules: When a board is not a repair candidate after inspection, Rongtao can quote a tested replacement if a matched assembly is available. Catalog photos are not live stock; this photographed PN has 0 inventory rows this snapshot.

Where Rongtao Does NOT Fit:

• No DIY Repair Guides: We do not provide component schematics, circuit-bypass instructions, or DIY tutorials for unqualified personnel to open energized medical equipment.
• No OEM authorization claims: Rongtao Medical is an independent service organization and parts supplier. We do not claim to be an authorized representative, agent, or warranty depot for Philips. OEM names and model designations identify equipment compatibility and coverage only.
• No Remote Certainty Without Inspection: We do not guarantee board repairability or exact pricing without inspecting high-resolution photographs of both board sides, label markings, and verified fault symptoms.
• No Unverified Suffix Cross-Swapping: We do not authorize or support silent swaps of leftover 454119653661 or subassembly 454110658301 as drop-in equivalents for catalog 454110649321.

Frequently Asked Questions (FAQs)

Is leftover 454119653661 the same board as catalog HD5 PC Motherboard 454110649321?
No. Leftover titles call 454119653661 an HD5 PC Main Board (philips-hd5-pc-main-board-454119653661), but the photo-verified catalog SKU is Philips HD5 PC Motherboard 454110649321. Match the physical etched number. Combined shopping titles are not interchange evidence.

Does a DOTmed listing that concatenates 454110649321-454119653661 mean I can swap either suffix into an HD5 cage?
No. Marketplace headlines concatenate numbers to capture search traffic. That is not engineering documentation. Do not swap unverified suffixes without matching the physical label.

Is HD5 the same machine as HD11 or HD15, and does K043535 or K081661 make this an end-of-support playbook?
No. The HD5 is an economy ultrasound cart with a distinct internal architecture. The HD11 (K043535 / K062247) and HD15 (K081661) utilize proprietary 45356-prefix electronic modules (such as Host PC 453561674461 and 453561317224) that cannot be installed into an HD5 chassis. Furthermore, named HD5 510(k) clearances are zero (n=0); clinical teams cannot derive an end-of-support timeline from HD11 or HD15 regulatory filings.

My search mixed HD5 with iFixit HD3, EPIQ 5, or a Philips HTB5520 home-theater board. Which page owns those?
These represent search engine homonym pollution. The Philips HTB5520 is a consumer Blu-ray sound system; YouTube TV SSB guides apply to consumer televisions; iFixit HD3 guides cover an earlier, distinct compact ultrasound platform excluded from Rongtao coverage; and the EPIQ 5 belongs on our Philips EPIQ / iU22 / iE33 Decision Path. None of these procedures apply to an HD5 cart.

The console has power but no scanning UI. Is that catalog 454110649321 or a leftover Assy?
When the cart powers fans but fails to display an operating system or scanning application, the ticket isolates to the host computing domain: either Catalog PC Motherboard 454110649321 or the boot media. Leftover Assy notes such as 454110658301 are not that catalog PC. Follow the Host/HDD Boot Failure Guide after matching the etched suffix.

Can I follow iFixit HD3, YouTube SSB replacement, or the AI Overview capacitor recipe to open this cart myself?
No. Diagnostic ultrasound consoles house high-voltage power supplies, sensitive beamformer channels, and complex backplanes. Attempting unauthorized consumer DIY repairs or swapping capacitors based on generic YouTube TV tutorials risks catastrophic circuit damage, electrical shock, and equipment condemnation. Board-level diagnosis and repair must be performed by qualified biomedical service engineers utilizing ESD-safe equipment and calibrated testing protocols.
