Procurement Notes

Verify the specific suffix 'SY' against the official AirBorn datasheet to confirm exact contact configuration and mounting variations. Ensure compatibility with mating plugs from the same W Series family. Confirm RoHS compliance status through manufacturer certificates prior to integration into regulated assemblies.

Selection Notes

Select this part for applications requiring straight, board-mount receptacles with solder cup terminations. Compare against similar models like WTAX or WTA series if different termination methods such as crimp or through-hole are required. Verify that the 20-position count and 2-row layout fit the PCB footprint constraints.

Part Context

This component belongs to the AirBorn W Series, a line of high-density rectangular connectors designed for harsh environments. The series offers various position counts and termination options to support diverse military and aerospace interconnect needs while maintaining strict dimensional and electrical standards.

Replacement Considerations

Cross-reference with M55302/64-A20X equivalents. Verify pinout orientation and mounting ear configurations before substituting with generic MIL-DTL-55302 parts.
