Procurement Notes

This component is officially discontinued and no longer manufactured by Qualcomm. Verification of availability should focus on surplus or secondary market sources rather than direct procurement from the manufacturer. Buyers must confirm the authenticity and condition of any available stock independently, as standard supply channels are closed for this part number.

Selection Notes

Designers requiring this specific 315MHz SAW filter must account for its obsolete status. Alternative components with similar electrical characteristics and package footprints should be evaluated for integration. Compatibility checks regarding impedance and bandwidth are necessary when substituting this unit in existing designs to ensure signal integrity.

Part Context
