Procurement Notes

This component is officially discontinued and no longer in production. Verification of availability should focus on surplus or secondary market sources rather than direct manufacturer distribution. Confirm the specific suffix and revision level against original design specifications to ensure compatibility, as end-of-life status may affect long-term supply stability and support availability.

Selection Notes

Designers requiring active alternatives should consult Skyworks for recommended replacement parts such as the SI47972A0GE1AM. Evaluate pinout compatibility and software migration requirements when transitioning from this obsolete model. Verify that the replacement component meets the same thermal and electrical specifications required for the target automotive or pro-audio application environment.
