Procurement Notes

Verify the specific suffix codes against official Molex/AirBorn documentation to confirm tail length, jackset configuration, and contact orientation. Ensure compatibility with mating plugs by checking hardware orientation standards. Confirm RoHS compliance status directly with the manufacturer as regulatory requirements may vary by production batch.

Selection Notes

Select this part when a 40-position dual-row receptacle is required for vertical board mounting. Verify that the 2.54 mm pitch aligns with the PCB layout design. Confirm that the socket contact type matches the intended pin-based mating connector. Check that the PPS material properties meet the thermal and chemical exposure requirements of the target application environment.

Part Context

This component belongs to the AirBorn W Series, a line of rectangular connectors designed for mission-critical applications. The series offers various position counts and termination options while maintaining strict adherence to MIL-DTL-55302 standards. The WTA designation specifically identifies a straight, dual-row receptacle configuration without mounting ears.

Replacement Considerations

M55302/64-C40F is a confirmed equivalent part number for this component. Verify physical dimensions and contact alignment before substitution.
