Headers, Receptacles, Female Sockets Procurement Notes

Verify availability directly with Molex or authorized distributors as this item may have limited distribution. Confirm that the specific ordering suffix matches the required contact configuration and mounting style. Ensure compliance with MIL-DTL-55302 standards for your application requirements before finalizing procurement orders.

Headers, Receptacles, Female Sockets Selection Notes

Select this component when a 50-position, 2-row receptacle is required for PCB mounting. The straight orientation and solder cup termination define the mechanical interface. Verify that the 5 A current rating and 1000 V insulation voltage meet the circuit demands. Consider the PPS housing material for thermal stability within the specified temperature range.

Headers, Receptacles, Female Sockets Part Context

This part belongs to the AirBorn W Series, which provides 0.100-inch pitch rectangular connectors. These connectors are designed for military and aerospace applications where durability and signal integrity are critical. The series offers various position counts and termination styles to suit different board layouts and environmental constraints.

Headers, Receptacles, Female Sockets Replacement Considerations

Compatible substitutes must match the MIL-DTL-55302 specification, 50-position count, and 2.54 mm pitch. Verify equivalent current ratings and temperature ranges. Cross-reference with other manufacturers offering similar W-Series form factors if direct AirBorn supply is unavailable.
