Procurement Notes

This component is officially marked as obsolete and no longer manufactured by Qualcomm. Verification of current availability through authorized distributors is required, as stock levels are not guaranteed. Engineers should review official Product Change Notifications to confirm end-of-life status before initiating any procurement processes or design-in activities.

Selection Notes

Due to the obsolete status of this part, alternative solutions must be evaluated for long-term supply chain stability. Designers should assess pin compatibility and electrical performance against newer generations of SAW filters from the same manufacturer family to ensure seamless integration into existing or new hardware architectures without requiring significant circuit redesign.

Part Context

The B39431 series represents Qualcomm’s portfolio of RF front-end filters. This specific model belongs to the SAW filter category, targeting narrowband applications around the 433 MHz ISM band. It serves as a passive component critical for maintaining signal integrity in wireless transmission paths, distinguishing itself through its specific acoustic resonance properties and compact footprint.

Replacement Considerations

Public records indicate that B39431B3735H110 is listed as a similar substitute for discontinued models in this series. Engineers should verify if this specific replacement meets the exact frequency and impedance requirements of the original design.
