Procurement Notes

Verify the specific suffix against official datasheets to confirm exact electrical tolerances and packaging configurations. Ensure compatibility with standard SMT reflow profiles during manufacturing. Confirm RoHS compliance status through current manufacturer documentation before finalizing procurement specifications.

Selection Notes

Select this component when a low-profile surface-mount microphone is required for compact designs. The 1.5 V operating voltage suits low-power applications. Verify that the 4 mm diameter fits within the designated acoustic port constraints on the target enclosure.

Part Context

This part belongs to the TOM series of microphones manufactured by PUI Audio. The series provides various form factors and mounting options for audio sensing needs. This specific model represents the surface-mount variant within the lineup.

Replacement Considerations

Consult official substitution guides for verified alternatives. Cross-reference pinouts and acoustic characteristics carefully.
