Procurement Notes

This component is officially obsolete and no longer manufactured by Qualcomm. Verification of availability should focus on existing stock from authorized distributors or secondary market suppliers. Buyers must confirm the authenticity and condition of any available units, as standard supply chain channels do not support new orders for this discontinued part number.

Selection Notes

Engineers requiring replacement components should evaluate parameter-equivalent alternatives within the same manufacturer portfolio. Selection criteria should prioritize matching center frequency, insertion loss, and physical footprint to ensure compatibility with existing circuit designs without requiring significant layout modifications.

Part Context

The B39921B3435U510 belongs to Qualcomm's RF front-end filter series, which includes various SAW and BAW technologies. These filters are engineered to address RF design challenges in mobile and IoT devices. This specific model represents a legacy solution for wireless audio bands, now superseded by newer generations of acoustic filter products.

Replacement Considerations

No direct public substitute part numbers are confirmed for this obsolete component. Engineers should consult official manufacturer documentation for current portfolio equivalents that meet similar electrical specifications and form factor requirements.
