Compatible Ultrasonix SonixSP probes are supplied today by the independent market—refurbished OEM units and tested aftermarket equivalents—because Ultrasonix stopped producing new transducers after the company was absorbed into BK Ultrasound in 2013. For the equipment discussed here, compatible or refurbished probe pricing depends on the exact model, condition, test documentation, availability, and order terms; compare a current RFQ with OEM supply. The SonixSP shares its connector and probe family with the rest of the Sonix line, so the compatible list below is long enough to cover nearly any clinical assignment the console is still doing.
Transducers Compatible with the Ultrasonix SonixSP
The SonixSP was positioned as the mid-range shared-service console of the Sonix family, aimed at departments that needed one system to rotate between abdominal, OB/GYN, vascular and small-parts work. These transducer models connect to it directly:
| Transducer | Array type | Frequency range | Primary clinical use |
|---|---|---|---|
| C5-2/60 | Convex | 2–5 MHz | Abdominal, OB/GYN, general imaging |
| C7-3/50 | Convex | 3–7 MHz | Abdominal, pediatric |
| EC9-5/10 | Endocavity | 5–9 MHz | Transvaginal and transrectal exams |
| L9-4/38 | Linear | 4–9 MHz | Vascular, deeper superficial structures |
| L14-5/38 | Linear | 5–14 MHz | Small parts, MSK, vascular access |
| L14-5W/60 | Wide linear | 5–14 MHz | MSK, breast, wide field of view |
| SA4-2/24 | Phased array | 2–4 MHz | Cardiac, transcranial |
| MC9-5/10 | Microconvex | 5–9 MHz | Pediatric, neonatal |
| 4DC7-3/40 | Motorized 4D convex | 3–7 MHz | 3D/4D obstetric imaging |
Decode the model name before ordering: L means linear, C convex, EC endocavity, SA phased array; the numbers give the frequency band in MHz and the footprint in millimeters after the slash. For a shared-service SonixSP the practical minimum set is a C5-2/60 for abdomen and obstetrics plus an L14-5/38 for vascular and small parts; sites with a gynecology load add the EC9-5/10. Buying the exact variant matters—an L14-5W/60 has a wider footprint than an L14-5/38 and will not suit intercostal or pediatric access even though the frequency band is identical.
Stocked examples from this family include the Ultrasonix L14-5 linear probe and the Ultrasonix C5-2/60 GPS convex probe, both of which connect directly to the SonixSP without adapters or software changes.
Why the OEM No Longer Sells New SonixSP Probes
Ultrasonix Medical Corporation of Richmond, British Columbia was acquired by Analogic in 2013 and folded into the BK Ultrasound organization, which today operates as BK Medical. The Sonix console line was subsequently wound down, and factory-new transducers for it are no longer produced. That does not make a working SonixSP obsolete. Hospitals and clinics keep these consoles in service for years because the image quality remains adequate for routine work and the replacement cost of a new console is difficult to justify.
The practical supply channel is therefore the independent market: tested refurbished OEM transducers and compatible aftermarket transducers built to mate with the Ultrasonix connector. For the equipment discussed here, compatible or refurbished probe pricing depends on the exact model, condition, test documentation, availability, and order terms; compare a current RFQ with OEM supply. Insist on a supplier that provides element-by-element phantom test reports and a warranty of at least six months before purchase.
Repair or Replace a Failing SonixSP Transducer?
Before ordering a replacement, have the existing probe evaluated. Common faults on Ultrasonix transducers—lens delamination, cable breaks near the strain relief, cracked connector shells and individual dead elements—are all repairable. A professional ultrasound probe repair For the equipment discussed here, repair pricing and turnaround depend on the fault, probe model, parts availability, and agreed test scope; request an assessment before comparing repair with replacement.
Repair is usually the better decision when the fault is mechanical (lens, cable, housing) and the array itself still tests clean. Replacement makes more sense when more than a handful of adjacent elements are dead, when the array has been struck or dropped, or when the same probe has already been repaired twice. For a discontinued platform such as the SonixSP, many facilities do both: repair the primary probe and keep a tested compatible spare on the shelf to avoid exam downtime.
How to Verify Compatibility Before You Order
Ultrasonix used one connector family across the Sonix consoles, but software licensing still matters. Confirm the following with any supplier before payment:
- Exact model designation. Order by the full Ultrasonix code (for example L14-5/38, not just “L14-5”), because the suffix defines the footprint.
- Software options on your console. A 4D transducer requires the 4D imaging license on the SonixSP; a probe the system firmware does not list will not be selectable even if it connects.
- Test documentation. Ask for an element-by-element report generated on a probe tester or phantom, not a photograph of an image on screen.
- Return terms. A reputable supplier accepts a return if the probe is not recognized by your specific console.
Send us your console serial number and current probe list and we will confirm compatibility, quote a tested replacement, or advise whether a repair of your existing transducer is the more economical route.
Evidence boundary and verification record
For Compatible Ultrasonix SonixSP Probes: Which Transducers Fit and Where to Get Them, a platform-level probe list helps create a shortlist but does not prove that every listed item fits every console revision. Record the full system and probe labels, connector views and the supplier’s written match basis, then attach item-specific condition and verification evidence to the quotation. A second reviewer should reconcile the model characters and every unresolved field before approval.
AIUM’s official statement supports regular assessment of transducer operation and quality control after repair. The BMUS multicentre survey provides fleet-level evidence that ultrasound probes can have faults requiring structured checks. These sources support the evidence boundary used for Compatible Ultrasonix SonixSP Probes: Which Transducers Fit and Where to Get Them; they do not prove compatibility, current stock or condition for an unidentified item.

Evidence questions
Does this evidence prove the exact compatibility described in Compatible Ultrasonix SonixSP Probes: Which Transducers Fit and Where to Get Them?
No. It defines what should be collected and reviewed. Exact compatibility remains tied to the complete labels, configuration, current documentation and written item-specific decision.
