Procurement Notes

Verify the obsolete status of this component before procurement planning. Confirm availability through authorized distributors or secondary market suppliers. Ensure compatibility with existing design specifications as replacement sourcing may require validation. Check for updated datasheets to confirm pinout and electrical characteristics remain consistent with original designs.

Selection Notes

Select this component only if the design specifically requires a 1.69 GHz SAW filter with 33 MHz bandwidth. Consider the 4 dB insertion loss impact on system sensitivity. Evaluate the 8-SMD package dimensions against available PCB real estate. Assess supply chain stability due to the discontinued product status when finalizing component choices.

Part Context

This part belongs to the Qualcomm RF front-end filter portfolio, which includes various SAW and BAW technologies. These components are engineered to support mobile and IoT connectivity solutions. The B39172 series typically addresses specific frequency requirements within wireless standards, providing essential filtering for transmitter and receiver paths in compact form factors.

Replacement Considerations

No public confirmed substitute part numbers are available for this obsolete component. Designers must evaluate alternative filters from other manufacturers or consider redesigning the RF stage to accommodate currently available SAW filters with similar electrical specifications.
