Procurement Notes
This component is officially designated as End of Life (EOL). Verification of the specific datasheet version and final availability status through authorized channels is required before implementation. Designers must confirm that the EOL notification applies to the exact suffix configuration intended for production use.
Selection Notes
Selection requires confirmation of compatibility with existing PCB footprints designed for 9.7 mm diameter microphones. Engineers should evaluate alternative components within the AUM series or other manufacturers if long-term supply continuity is a critical project requirement due to the discontinued status.
Part Context
The AUM-5047L-4-R belongs to the AUM series of audio devices produced by PUI Audio. This series encompasses various electret condenser microphones engineered for standard audio applications. The part represents a specific variant within this lineup characterized by its 680 Ohm impedance and specific dimensional constraints.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Due to the End of Life status, engineers must identify compatible alternatives based on matching electrical parameters and mechanical dimensions from other suppliers.
