Microphones Procurement Notes

Verify current availability status as this specific part number may be subject to end-of-life notices or discontinuation events. Confirm RoHS compliance documentation matches the required revision level for your manufacturing process. Ensure that the 2.57mm footprint aligns precisely with your PCB layout constraints before finalizing procurement orders.

Microphones Selection Notes

Select this component when a low-profile microphone solution is required for integration into tight spatial envelopes. The wide operating voltage range provides flexibility in circuit design without requiring complex biasing networks. Consider the 2.57mm size constraint against available board real estate and ensure compatibility with existing acoustic housing designs.

Microphones Part Context

This microphone is part of Knowles' broader FG series portfolio, which focuses on miniaturized acoustic transducers. The series typically serves the consumer electronics market where size reduction is critical. The P03 suffix likely denotes specific packaging or terminal configuration details within the manufacturer's internal coding system for distribution and assembly purposes.

Microphones Replacement Considerations

Check for official substitution notices from Knowles regarding this discontinued or obsolete part. Verify if newer revisions of the FG series maintain identical pinouts and acoustic characteristics. Cross-reference with similar 2.57mm profile microphones from other manufacturers only if electrical parameters match exactly.
