Philips D1914C (21221B) Pencil/CW Ultrasound Probe

When your department needs to replace or add a dedicated pencil/cw Doppler transducer for the HP Sonos 4500, 5500, 7500 or the Philips EnVisor, this catalogue record anchors the sourcing decision for the D1914C (21221B). The unit is listed as new aftermarket-compatible, so it sits alongside the repair-service option for the original Philips transducer of the same model. Buyers typically arrive here after confirming the exact connector and frequency behaviour against their installed base, and this record gives the compatibility matrix in one place.

Within the Pencil & CW Doppler Probes section, this entry is the sibling to the 21221A listing, so the two records share the same housing and array type but differ by the suffix in the model number. Procurement teams should treat each variant as a separate line item in their inventory system. Every commercial point, including after-sales support, inspection scope and delivery timing, is agreed individually per order after direct contact with the supplier, so no blanket terms appear on this page.

Frequently asked questions

For this model, what after-sales support comes with this probe when I order it?

Support is settled case by case for each unit, because the level of inspection, repair coverage and return handling varies between individual probes. You will receive the precise support terms with the quotation for the exact serial number and condition you select.

Before you order: how does this 21221B listing differ from the 21221A version beside it?

Both are pencil/cw transducers for the same compatible systems, but the model suffix differs. The 21221A has its own catalogue record, so confirm which suffix your system references before adding either to your procurement list.

Are the condition options the same for every D1914C unit listed?

No. This record lists the new aftermarket-compatible option and a repair route for the original Philips transducer. Each individual unit may be offered under either condition, and the quotation will state what applies to that specific probe.

Does this probe work with the EnVisor system for continuous wave Doppler exams?

The site data lists the Philips EnVisor among the compatible systems, along with three HP Sonos models. Application details are not part of this catalogue record, so verify the intended clinical use with the supplier before committing to the order.
