Procurement Notes

This component is officially discontinued and no longer manufactured. Verification of availability should focus on obsolete stock or secondary market sources rather than direct procurement from the manufacturer. Ensure any acquired units are handled according to electrostatic discharge control procedures as they are sensitive components.

Selection Notes

Selection is limited due to the discontinued status of this specific part number. Engineers requiring equivalent performance must identify alternative SAW filters that match the 942.5 MHz center frequency, 35 MHz bandwidth, and 6-SMD leadless footprint constraints while ensuring compatibility with existing GSM system architectures.

Part Context

This device belongs to the Qualcomm RF front-end (RFFE) filter portfolio, which includes discrete high-performance duplexers and extractors. These products leverage advanced acoustic technologies to address RF design challenges in wireless connectivity applications, supporting both consumer and infrastructure markets.

Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Due to the discontinued status, engineers must evaluate third-party equivalents based on electrical specifications and mechanical dimensions.
