Microphones Procurement Notes

Verify component status as the EK-23032-A21 is listed as obsolete and no longer manufactured by Knowles. Confirm availability through authorized distributors or secondary market sources. Ensure compatibility with existing PCB layouts and soldering profiles. Check for RoHS compliance documentation if required for specific regulatory standards. Validate that substitute components meet identical electrical and mechanical specifications.

Microphones Selection Notes

Select this component for designs requiring high-performance audio capture in limited physical spaces. Consider the analog output interface when designing pre-amplification circuits. Evaluate the 50 μA supply current against total system power budgets. Ensure the 1.3 V rated voltage aligns with the target application's power supply rails. Assess the 100 Hz to 10 kHz frequency response against acoustic requirements.
