Microphones Procurement Notes

Verify the specific revision status as some sources indicate this part may be obsolete or discontinued. Confirm mechanical compatibility with existing PCB footprints due to the precise 5.56 x 3.98 x 2.21 mm form factor. Ensure that the required bias voltage falls within the 0.9 V to 10 V operational window before finalizing procurement orders.

Microphones Selection Notes

Select this component when an omnidirectional response is critical for ambient noise capture rather than directional isolation. The wide voltage tolerance allows for use in both low-power battery devices and higher-voltage industrial applications. Consider the limited upper frequency response of 5 kHz, which is suitable for voice frequencies but not for high-fidelity audio recording applications.

Microphones Part Context

This microphone belongs to the EK series manufactured by Knowles, specializing in acoustic sensing components. The series is known for integrating electret condenser elements into small surface-mount packages. This specific model represents a standard solution for general-purpose voice detection in embedded systems.

Microphones Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Due to the potential obsolete status indicated by some distributors, alternative sourcing should focus on verifying current production status or identifying equivalent omnidirectional electret microphones with matching dimensional constraints.
