Headers, Male Pins Procurement Notes

Verify the specific suffix codes against the manufacturer datasheet to confirm termination plating and polarization settings. Ensure compatibility with mating receptacles within the same R Series family. Confirm RoHS status requirements as standard variants may not be compliant. Validate that the right-angle orientation matches the PCB layout constraints before finalizing procurement orders.

Headers, Male Pins Selection Notes

Select this model when a high-pin-count, right-angle plug is required for MIL-DTL-55302 applications. The 70-position dual-row design supports dense circuit routing. Consider the 1.91 mm pitch for trace spacing limitations. Verify that the 3 A current rating per contact meets the system load requirements. Ensure the through-hole termination method aligns with the assembly process capabilities.

Headers, Male Pins Part Context

This component belongs to the AirBorn R Series, a line of rectangular connectors designed for harsh environments. The series offers various configurations including straight and right-angle mounts with different row counts. The RM252 prefix typically denotes a plug variant within this standardized military-grade ecosystem, ensuring interchangeability with other compatible series components.

Headers, Male Pins Replacement Considerations

Direct substitutes must match the MIL-DTL-55302 specification, 70-position count, and right-angle form factor. Verify identical pinout arrangements and polarization keys to ensure mechanical and electrical compatibility. Cross-reference with official Molex/AirBorn replacement guides for updated part numbers.
