Procurement Notes
Verify the specific suffix B102B against official Panasonic Semiconductor documentation to confirm exact acoustic tolerances and pinout configuration. Ensure compatibility with required biasing circuits and mechanical mounting standards before finalizing procurement orders.
Selection Notes
Select this component when an omnidirectional response is required for general-purpose voice capture. Compare sensitivity specifications against alternative models like the WM-61A or WM-63PR if different acoustic profiles are needed. Confirm package dimensions match the target enclosure constraints.
Part Context
This part belongs to the WM-61 series of omnidirectional electret condenser microphones. It shares similar acoustic principles with other models in the lineup but may differ in specific sensitivity ratings or mechanical housing details defined by the B102B designation within Panasonic's semiconductor product catalog.
Replacement Considerations
The WM-61A and WM-63PR are listed as similar parts in public databases. Verify pin compatibility and acoustic sensitivity curves before substitution, as these parameters vary between specific model numbers within the same family.
