Procurement Notes

Verify the specific suffix B82 against official datasheets to confirm environmental sealing or plating variations. Confirm RoHS compliance status directly with the manufacturer as documentation details may vary. Ensure the ordering part number matches the exact contact configuration and mounting style required for the target PCB layout before finalizing procurement.

Selection Notes

Select this component when a MIL-DTL-55302 compliant receptacle is required for high-reliability applications. The 20-position, 2-row configuration suits dense interconnect needs. Verify that the 2.54 mm pitch aligns with the design footprint. Ensure the operating environment stays within the specified -65 C to +125 C range for optimal performance.

Part Context

This part belongs to the AirBorn W Series, a line of rectangular connectors designed for harsh environments. The WTA designation indicates a straight receptacle without mounting ears. This series provides robust interconnection solutions for aerospace and defense sectors where vibration and temperature extremes are prevalent.

Replacement Considerations

M55302/64-C20F is a documented alias for this component. Cross-reference mating plugs from the same W Series family to ensure mechanical compatibility. Verify that substitute parts maintain identical pinout orientation and contact gender specifications.
