Procurement Notes

This component is officially marked as obsolete and is no longer manufactured by Qualcomm. Procurement must rely on secondary market distributors or surplus inventory sources. Verification of authenticity and physical condition is critical when sourcing from non-original channels. Designers should initiate immediate replacement strategies to ensure long-term supply chain stability and avoid discontinuation risks associated with end-of-life parts.

Selection Notes

Engineers selecting this part must account for its discontinued status. While the 303.8 MHz SAW specification suits specific legacy remote control designs, new developments should prioritize active components. Compatibility checks are required if substituting within existing hardware architectures. The 8-SMD package footprint remains a key constraint for board layout adjustments during migration to newer, available filter technologies.

Part Context

The B39152B5163U410 belongs to Qualcomm's broader portfolio of RF front-end filters, which includes advanced technologies like ultraBAW and TC-SAW. This specific model represents an earlier generation SAW solution tailored for lower-frequency bands. Its inclusion in the RFFE lineup highlights Qualcomm's historical focus on providing discrete filtering solutions for consumer electronics and IoT devices requiring reliable signal isolation.

Replacement Considerations

As the B39152B5163U410 is obsolete, direct manufacturer replacements are unavailable. Engineers must identify third-party compatible SAW filters matching the 303.8 MHz center frequency and 8-SMD package. Cross-referencing electrical parameters such as insertion loss and bandwidth is essential to maintain system performance without redesigning the RF circuit.
