Procurement Notes

Verify current availability as some sources list this part as obsolete while others indicate active status. Confirm specific manufacturing lot dates and RoHS compliance documentation directly with authorized distributors. Ensure the 9 V operating supply requirement matches your system design before procurement.

Selection Notes

Select this component when high environmental protection (IP67) is required alongside standard analog microphone functionality. Consider the 0.500-inch diameter constraint for enclosure design. Verify compatibility with 9 V biasing requirements within the target application circuit.

Part Context

This microphone is part of the Knowles VWP series, which focuses on robust audio sensing solutions. It serves as an alternative to standard microphones in harsh environments where moisture or dust ingress would typically cause failure. The analog output simplifies integration into existing audio pre-amplifier stages.

Replacement Considerations

Check for updated revisions within the VWP series if this specific model is discontinued. Ensure any substitute maintains the IP67 rating and 9 V operating voltage to preserve system performance and physical fit.
