Replacement Ultrasound Probe Cable

When a critical ultrasound probe cable fails, you need a replacement that meets the original specification — not an approximation. We manufacture OEM-equivalent replacement ultrasound probe cables matching AWG, impedance (50 Ω ±2 Ω), phase-matched electrical length (±1%), outer diameter, and connector interface. Delivered in 3–5 weeks — versus 8–16 week OEM lead times that leave probes sitting idle in your repair queue.

This page is for probe repair facilities, OEM second-source procurement teams, and medical device companies building supply chain resilience. We are a cable manufacturer, not a parts retailer. Every replacement cable is manufactured to specification with full electrical test documentation.

Compatible Platforms

Note: We manufacture cables to match original specifications. We are not affiliated with or endorsed by any of the platform manufacturers listed above. Platform names are used solely to identify cable compatibility.

Why Use a Manufactured Replacement vs. OEM Channel

Faster Delivery
Original OEM cable procurement channels typically require 8–16 weeks — sometimes longer when inventory is allocated. Our manufactured replacement delivers in 3–5 weeks. For probe repair facilities, this means faster repair turnaround and higher probe utilization rates.

Second-Source Qualification
Establishing an approved second-source cable supplier reduces single-supplier dependency — a growing concern as global supply chains face disruptions. Our ISO 9001 documentation package supports formal second-source qualification in your vendor management system.

End-of-Life Replacement
When an OEM discontinues a probe model, replacement cables become unavailable through original channels. We can manufacture cables to the original specification indefinitely, extending the service life of your probe fleet.

Custom Lengths
OEM channels typically supply fixed cable lengths. We manufacture to your exact required length (±5 mm tolerance), which simplifies probe housing integration and eliminates excess cable management inside the handle.

Cost Structure
Manufactured replacement cables are typically 25–40% lower cost than OEM channel pricing at equivalent specification, with savings increasing at higher volumes (50+ assemblies per order).

How Our Replacement Process Works

Step 1: Send Original Cable Specification or Failed Sample
Share the original cable drawing, datasheet, or a failed cable sample. We need: AWG gauge, core count, impedance, phase-match tolerance, connector type (both ends), cable length, jacket material, and any special requirements (biocompatibility, sterilization compatibility).

If you have a drawing → Quote in 48 hours.
If you have a failed sample only → We reverse-engineer (add 3–5 business days).

Step 2: Specification Matching & Formal Quote (48 hours)
Our engineering team confirms all parameters match the original. You receive a formal quote including: unit price at prototype and production volumes, specification comparison document (our cable vs. original), MOQ, and delivery timeline.

Step 3: Prototype Samples with Full Verification (3–5 weeks)
We manufacture 5–10 prototype assemblies and ship with:
- Specification comparison document (parameter-by-parameter vs. original)
- 100% electrical test records (continuity, TDR impedance, HiPot, insulation resistance)
- TDR phase-match certificate (if phase-matched)
- RoHS/REACH declaration
- Certificate of Conformance

Step 4: Acceptance Testing at Your Facility
Install prototype cables in your probes and run through your standard incoming inspection and functional test. Verify image quality, signal integrity, and mechanical fit. If the replacement passes your acceptance criteria, the cable is qualified.

Step 5: Production Orders
After qualification, place repeat production orders at agreed pricing. Standing order programs available for high-volume repair operations (monthly or quarterly scheduled deliveries).

Reverse Engineering from Failed Sample

If no drawing or datasheet is available, send us the failed cable. Our reverse-engineering process:

Electrical Analysis
- TDR measurement: impedance profile, electrical length, velocity of propagation per channel
- Capacitance and DC resistance measurement
- Phase-match analysis across all channels (if multi-core)

Physical Analysis
- Laser micrometer: cable OD, dielectric OD, conductor diameter
- Cross-section microscopy: layer identification, braid angle, foil wrap direction
- Material identification: jacket (PVC/PUR/PFA/FEP), dielectric (ePTFE/FEP/PTFE), conductor plating

Connector Analysis
- Connector identification: manufacturer, series, contact count, pitch
- Pin-out mapping
- Termination method: solder, crimp, or weld

Turnaround: 3–5 business days from sample receipt to specification document. Additional cost: engineering fee quoted per project (typically $500–$1,500 depending on complexity, credited against first production order of 50+ assemblies).

Specification Comparison — What We Match

Documentation Package

Every replacement cable ships with a complete documentation package supporting your quality system and regulatory files:

- Certificate of Conformance (CoC) — per lot, referencing your PO and cable specification
- 100% Electrical Test Records — per serial number: continuity, TDR impedance, HiPot 500V DC, insulation resistance ≥ 100 MΩ
- TDR Phase-Match Certificate — per channel propagation delay (phase-matched cables only)
- Specification Comparison Document — parameter-by-parameter comparison vs. original cable
- RoHS/REACH Declaration of Conformity
- ISO 10993 Biocompatibility Declaration (if applicable)
- Material Certificate — conductor, dielectric, jacket material identification
- First Article Inspection Report (FAIR) — available on request for first production lot

This package supports FDA 510(k) change notifications, CE Technical File updates, and ISO 13485 supplier qualification requirements.

Volume and Pricing Structure

MOQ after qualification: 10 assemblies per order.
Tooling: No tooling charges for standard connector types. Custom overmold tooling quoted separately (one-time, typically $2,000–$5,000).

Frequently Asked Questions

Can you replace a cable based on a failed sample rather than a drawing?

Yes. Send the failed cable and we reverse-engineer via TDR (impedance, electrical length, VoP), optical measurement (cable OD, dielectric OD), and material analysis (jacket ID). Adds 3–5 business days to generate the replacement specification. Engineering fee typically $500–$1,500, credited against first production order of 50+ assemblies.

Do replacement cables require FDA 510(k) notification?

Typically no — a supplier change maintaining the same cable specification usually qualifies as a non-significant change under 21 CFR Part 807. The specification comparison document we provide supports your change control evaluation. However, this is a regulatory determination that must be made by your regulatory affairs team, not by us as a cable supplier.

Will the replacement cable void the probe warranty?

If the probe is already out of OEM warranty (which is the case for most probes entering third-party repair), this is not a factor. For probes under warranty, check your OEM service agreement. Our documentation package provides the specification evidence needed for any warranty discussion.

How close is "OEM-equivalent"?

We match every published and measurable parameter: AWG, impedance, phase match, capacitance, OD, flex life, materials. The elements we cannot match are proprietary markings, OEM part numbers, and any undocumented internal specifications. Electrically and mechanically, the cable performs identically.

What if the replacement doesn't pass our acceptance test?

We work with you to identify the gap. If it is a specification issue on our side, we re-manufacture at no additional cost. In 4+ years of replacement cable production, our first-pass acceptance rate exceeds 97%.

Minimum order for replacement cable?

5 assemblies for qualification. After qualification, repeat orders of 10+ assemblies accepted. Standing order programs available for high-volume repair operations (probe repair facilities processing 20+ probes/month).

Can you also supply the connector?

Yes. We source and terminate connectors as part of the complete cable assembly. For I-PEX, HIROSE, and LEMO connectors, we maintain inventory of common series. Custom or OEM-specific connectors may require additional lead time (1–2 weeks).
