Procurement Notes

Verify the specific suffix 'PBJ' against the manufacturer's official datasheet to confirm packaging type and terminal configuration. Ensure the operating voltage requirements align with the 2 VDC specification. Confirm RoHS compliance status through the latest product change notification or certification documents provided by Same Sky.

Selection Notes

Select this component when an omnidirectional response is required for voice capture applications. The low power consumption of 400 uA makes it suitable for battery-operated devices. Verify that the 6 mm diameter fits within the available PCB real estate and that the 2.7 mm height constraint is met.

Part Context

This microphone belongs to the CMC-2742 series from Same Sky, designed for compact audio input solutions. The series offers various packaging options while maintaining consistent electrical performance characteristics such as sensitivity and impedance levels suitable for general-purpose voice detection tasks.

Replacement Considerations

The CMEJ-0627-42-P is a comparable alternative in the Same Sky portfolio with similar electrical parameters including -42 dB sensitivity and 2 V operation. Verify mechanical footprint compatibility before substitution.
