Headers, Male Pins Procurement Notes

Verify the specific suffix 'X' against official datasheets to confirm plating and material specifications. Ensure compatibility with mating female receptacles within the same W Series family. Confirm that the free-hanging mounting style aligns with the mechanical constraints of the target assembly before finalizing procurement orders.

Headers, Male Pins Selection Notes

Select this part when a high-density 66-position male connector is required for PCB or cable assemblies. The 2.54 mm pitch allows for standard spacing layouts. Consider the PPS housing material for thermal stability up to +125 C. Ensure the application environment does not exceed the specified temperature range of -65 C to +125 C.

Headers, Male Pins Part Context

This component belongs to the AirBorn W Series, which offers compact and rugged rectangular connectors. The series is characterized by its MIL-DTL-55302 compliance and availability in various contact counts ranging from 1 to 208 positions. The M55302/57B66X represents a specific high-pin-count variant optimized for complex signal routing needs.

Headers, Male Pins Replacement Considerations

Direct substitutes include other M55302/57B66X units from authorized manufacturers. Cross-referencing with generic MIL-DTL-55302 equivalents requires strict verification of pinout, housing dimensions, and contact gender to ensure functional interchangeability without modification.
