Headers, Receptacles, Female Sockets Procurement Notes

Verify specific ordering suffixes such as B82 against official Molex/AirBorn documentation to ensure correct polarization and accessory inclusion. Confirm RoHS compliance status and lead times directly with the manufacturer, as this component may be subject to factory special order requirements. Validate that the selected variant matches the required circuit count and termination style for your design.

Headers, Receptacles, Female Sockets Selection Notes

Select this part when a 20-position dual-row MIL-DTL-55302 receptacle is required. Ensure compatibility with corresponding plug connectors from the same W Series family. Verify that the 2.54 mm pitch and straight mounting angle fit the PCB layout constraints. Consider the PPS material properties for thermal resistance and the gold plating for contact durability in harsh environments.

Headers, Receptacles, Female Sockets Part Context

This component belongs to the AirBorn W Series, a line of high-reliability rectangular connectors designed for demanding environments. The series offers various position counts and termination options while maintaining strict adherence to military standards.
