Headers, Male Pins Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm exact contact plating thickness, tail length, and polarization requirements. Ensure compatibility with mating receptacles within the R Series family. Confirm that the right-angle orientation and solder cup termination meet the specific mechanical constraints of the target printed circuit board assembly before finalizing procurement.

Headers, Male Pins Selection Notes

Select this component when a high-density 40-position connection is required in space-constrained environments necessitating a right-angle profile. The MIL-DTL-55302 compliance ensures suitability for harsh operational conditions. Verify that the 3 A current rating and 750 V voltage limits align with the system's electrical demands. Consider the thermal stability of the PPS material for high-temperature soldering processes.

Headers, Male Pins Part Context

This part belongs to the AirBorn R Series, a line of rectangular connectors designed for demanding applications. The series is characterized by its compact size, high reliability, and adherence to strict military standards. The RM252 prefix typically denotes a plug configuration within this ecosystem, distinguishing it from receptacle or cable mount variants found in the broader product catalog.

Headers, Male Pins Replacement Considerations

Compatible substitutes must match the MIL-DTL-55302 standard, 40-position count, 1.91 mm pitch, and right-angle form factor. Cross-reference mating part numbers to ensure interface compatibility. Verify equivalent electrical ratings and material specifications for the replacement unit.
