Procurement Notes

This component is officially marked as obsolete and is no longer manufactured by Qualcomm. Procurement should focus on verified parameter-equivalent substitutes such as the B39242B9413K610. Verify current availability through authorized distributors, as stock levels are limited or non-existent. Ensure any replacement part matches the original electrical specifications and physical footprint to maintain system integrity.

Selection Notes

Selection is constrained by the obsolete status of this specific part number. Engineers must evaluate alternative components that offer identical center frequency, bandwidth, and insertion loss characteristics. Physical compatibility requires matching the 5-SMD no-lead package dimensions of 2.00 mm x 1.40 mm. Prioritize parts with confirmed RoHS compliance and similar moisture sensitivity ratings to ensure reliable integration into existing manufacturing processes.

Part Context

This SAW filter belongs to Qualcomm's RF front-end portfolio, which includes various acoustic technologies like ultraSAW and TC-SAW. These components are engineered to address RF design challenges in mobile and IoT devices. The B39242 series specifically targets Bluetooth frequencies, providing essential filtering for reliable wireless performance in consumer electronics and industrial applications.

Replacement Considerations

The B39242B9413K610 is documented as a parameter-equivalent substitute. Verify that the replacement maintains the same 2.442 GHz center frequency and 5-SMD package dimensions. Confirm that insertion loss and bandwidth specifications remain within acceptable tolerances for the target application.
