Microphones Procurement Notes

Verify the specific datasheet version for the MO044202-4 to confirm exact electrical tolerances and mechanical drawings. Ensure compatibility with the 2 V operating voltage and 500 uA bias current requirements in the target circuit design. Confirm that wire lead termination matches the assembly process.

Microphones Selection Notes

Select this component when an omnidirectional response is required within a 4 mm diameter constraint. The -42 dBA sensitivity and 2.2 kOhm impedance define the interface characteristics. Verify that the wire lead termination style fits the board layout compared to surface mount alternatives.

Microphones Part Context

This part belongs to the MO series of microphones from DB Unlimited, which focuses on compact audio solutions. The MO044202-4 shares similar physical dimensions with the MO044202-3 but may differ in specific electrical parameters or manufacturing revisions. It serves as a standard electret microphone option for general audio applications.

Microphones Replacement Considerations

Publicly confirmed substitute part numbers for the MO044202-4 are not available in the provided documentation. Cross-referencing requires matching the 4 mm diameter, 2.2 kOhm impedance, and -42 dBA sensitivity specifications.
