Microphones Procurement Notes

Verify the active status of this component as it is listed as obsolete or end-of-life by the manufacturer. Confirm availability through authorized distributors or surplus suppliers. Ensure that any replacement sourcing maintains compatibility with the original electrical specifications and physical dimensions required for the intended application.

Microphones Selection Notes

Select this model only if the specific low-voltage operating range of 0.9 V to 1.6 V aligns with the system power budget. Consider the circular form factor and top-port orientation during PCB layout planning. Evaluate alternative components if long-term supply stability is a critical requirement due to the discontinued status.

Microphones Part Context

This part belongs to the FG series of miniature microphones manufactured by Knowles. It is distinct from other series such as EK or EK-26695-C36 which may offer different frequency responses or physical sizes. The FG series typically targets space-constrained portable electronics where small footprint and consistent performance are prioritized.

Microphones Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Due to the end-of-life status, engineers must identify equivalent components based on matching pinout, sensitivity, and dimensional constraints.
