Headers, Receptacles, Female Sockets Selection Notes

Select this component when a 40-position, dual-row MIL-Spec receptacle is required. The 2.54 mm pitch dictates compatible PCB footprint design. Verify that the 5 A current rating and 1 kV voltage withstand meet system electrical requirements. Consider the straight mounting angle and through-hole termination method during mechanical integration planning.

Headers, Receptacles, Female Sockets Part Context

This part belongs to the AirBorn W Series, which provides high-density interconnect solutions. As an AirBorn product now under Molex, it maintains legacy military-grade reliability standards. The W Series is characterized by its robust construction and suitability for harsh environments requiring durable electrical connections.

Headers, Receptacles, Female Sockets Replacement Considerations

Direct substitutes include other W Series variants such as WTB50SAD9J or WTB20SAD9SY-L87, provided the pin count and form factor align with the design constraints. Verify that any replacement maintains the same MIL-DTL-55302 compliance and contact plating specifications.
