Procurement Notes

Verify current availability status carefully, as this component has been withdrawn from the mobile communications market. Confirm if the unit is intended for industrial or infrastructure use rather than mobile handsets. Check for official Product Change Notifications (PCN) regarding end-of-life procedures. Ensure compatibility with existing designs before sourcing, as supply may be limited to stock clearance or specific non-mobile sectors.

Selection Notes

Consider that this SAW filter is designated for withdrawal in mobile segments. Evaluate alternative components from the same manufacturer that utilize ultraSAW or ultraBAW technologies for newer designs. Assess whether the specific frequency characteristics meet system requirements without relying on discontinued parts. Review updated datasheets for any changes in packaging or electrical specifications compared to previous revisions.
