Procurement Notes

This component is officially marked as obsolete and is no longer manufactured by the supplier. Verification of current availability requires checking authorized distributors for remaining stock or end-of-life status confirmation. Designers should initiate replacement qualification processes immediately to ensure supply chain continuity for active projects.

Selection Notes

Select this part only if legacy design compatibility is required. Due to its obsolete status, alternative components from the same manufacturer family or third-party equivalents must be evaluated for pinout and electrical parameter matching. Verify that the 1.865/1.895 GHz frequency range aligns with specific band requirements.

Part Context

This device belongs to the Qualcomm RF front-end filter portfolio, which includes ultraBAW, ultraSAW, and TC-SAW technologies. These filters are engineered for 5G/4G, Wi-Fi, and GNSS applications to support energy-efficient multiband devices in slim form factors across consumer and infrastructure markets.

Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. As the product is obsolete, engineers must identify equivalent SAW filters with matching 1.865/1.895 GHz center frequencies and 30 MHz bandwidth specifications.
