Procurement Notes

This component has reached end-of-life status and is no longer in production. Verification of availability should focus on obsolete stock or authorized distributors holding remaining inventory. Buyers must confirm the specific revision level and ensure compatibility with existing designs before procurement, as supply continuity is not guaranteed.

Selection Notes

Engineers selecting this part should account for its discontinued status when designing new products. The 8-SMD package requires appropriate PCB footprint considerations. Designers should evaluate the 3.3dB insertion loss and 220kHz bandwidth against system requirements to ensure adequate signal integrity for the intended 433.42MHz application.

Part Context

This device belongs to the Qualcomm RF front-end filter portfolio, which includes components for wireless, automotive, and industrial applications. The B39431 series represents SAW filters optimized for specific frequency bands. This particular model targets the 433MHz ISM band commonly used in remote control and short-range communication devices.

Replacement Considerations

The B39431B3735H110 is listed as a similar replacement option. Engineers should verify electrical parameter compatibility, including center frequency and bandwidth, before substituting this obsolete part with the alternative.
