Microphones Procurement Notes

Verify current manufacturing status as the EK-27263-C75 may be obsolete or discontinued. Confirm availability through authorized distributors or check for direct substitute part numbers if production has ceased. Ensure compatibility with existing PCB layouts before procurement.

Microphones Selection Notes

Select this component for applications requiring small footprint microphones with omnidirectional pickup patterns. Consider the 1.3 V operating voltage and 4.4 kOhm impedance when designing biasing circuits. Evaluate sensitivity requirements against environmental noise levels.

Microphones Part Context

This model belongs to the EK series of subminiature electret microphones from Knowles Electronics. The series is characterized by low-profile designs intended for integration into portable audio equipment and communication devices where size constraints are critical.

Microphones Replacement Considerations

Public sources indicate that the EK-27263-C75 is obsolete and no longer manufactured. Direct substitutes within the same series, such as the EK-27263-C05, should be evaluated for pin compatibility and electrical parameter alignment.
