Procurement Notes

This component is officially classified as obsolete and has been discontinued by the manufacturer. Verification of current availability should be conducted through authorized distributors or secondary market suppliers. Engineering change notices indicate production cessation. Designers must confirm end-of-life status before finalizing procurement plans due to limited supply chains.

Selection Notes

Engineers should evaluate this part against active alternatives given its discontinued status. The specific 433.92 MHz center frequency and 220 kHz bandwidth define its operational niche. Package dimensions and thermal characteristics remain consistent with the B39431 series family. Compatibility checks are required if substituting with newer generations from the same manufacturer line.

Part Context

This SAW filter belongs to the B39431 series produced by Qualcomm RF Front-End filters. It serves as a passive optical network component variant within broader RFFE product lines. The device integrates into signal conditioning architectures requiring precise frequency selection. Its design supports standard SMD mounting processes for electronic assemblies.
