Procurement Notes

Verify the obsolete status of this part number before procurement planning. Confirm if the designated substitute B39321B3761Z810 meets all design requirements. Check current availability through authorized channels as standard supply may be limited due to discontinuation.

Selection Notes

Select this component only if the specific 315MHz frequency and 200kHz bandwidth align with the system architecture. Consider the higher insertion loss compared to newer alternatives when evaluating signal integrity requirements for the target application.

Part Context

This SAW filter belongs to the Qualcomm RF front-end portfolio, targeting low-frequency ISM band applications. It represents an earlier generation discrete filter solution prior to the integration of more advanced ultraSAW technologies found in current product lines.

Replacement Considerations

The B39321B3761Z810 is listed as a similar replacement. Verify pin compatibility and electrical parameter alignment, particularly the reduced insertion loss and increased bandwidth of the substitute.
