Procurement Notes

Verify the specific datasheet version and RoHS compliance status directly with the manufacturer or authorized distributors before procurement. Confirm that the 75MHz specification aligns with your system requirements. Ensure handling procedures comply with moisture sensitivity level guidelines during assembly. Cross-reference part numbers to avoid confusion with similar variants in the B39172 series.

Selection Notes

Select this component when a narrow-band SAW filter is required for 75MHz remote control signals. Consider its low insertion loss characteristics for maintaining signal integrity in passive RF paths. Evaluate the physical dimensions against available board space. Compare performance metrics against alternative ultraSAW or TC-SAW solutions if higher frequencies or broader bandwidths are needed.

Part Context

This component belongs to Qualcomm's extensive portfolio of RF front-end filters, which includes various SAW and BAW technologies. These products are engineered to address challenges in 5G, 4G, Wi-Fi, and GNSS systems. The B39172 series specifically targets cost-effective and compact filtering solutions for non-cellular wireless applications, supporting the development of energy-efficient devices.

Replacement Considerations

Check for direct substitutes within the B39172 family such as B39172B5109U410, though frequency differences apply. Verify compatibility with existing PCB footprints and impedance matching networks. Consult official replacement guides for discontinued or updated versions.
