Microphones Procurement Notes

Verify the specific suffix code (e.g., EK-23133-005 or EK-23024-C04) to ensure correct sensitivity and packaging specifications. Confirm RoHS compliance status through official datasheets before procurement. Validate that the selected variant matches the required acoustic performance parameters for the target application.

Microphones Selection Notes

Select this component based on its compact physical footprint and standardized SMD interface. Ensure the -53 dBA sensitivity meets the signal-to-noise requirements of the audio circuit. Verify compatibility with the intended PCB layout and acoustic enclosure design constraints.

Microphones Part Context

This part belongs to the EK/EY series of microphones produced by Knowles. These components are designed for general-purpose audio applications requiring reliable sound detection in small form factors.

Microphones Replacement Considerations

Consult official substitution lists for compatible variants within the EK/EY series. Verify dimensional and electrical parameter alignment before replacing existing inventory.
