Headers, Male Pins Procurement Notes

Verify the specific suffix codes against the manufacturer datasheet to confirm termination plating and polarization options. Ensure compatibility with mating receptacles in the same R Series family. Confirm RoHS compliance status as it may vary by production batch or region. Validate that the right-angle mounting style aligns with the mechanical constraints of the target assembly.

Headers, Male Pins Selection Notes

Select this part when a high-pin-count, right-angle connection is required for MIL-Spec environments. The 1.91 mm pitch allows for dense circuit placement while maintaining standard spacing. Consider the PPS material properties for applications requiring resistance to heat and chemicals. Ensure the through-hole termination method matches the PCB fabrication capabilities and mechanical stress requirements of the design.

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 plugs, different row counts, and multiple termination styles. The RM252 prefix indicates a right-angle plug with a plastic body, distinguishing it from metal shell variants in the broader product portfolio.

Headers, Male Pins Replacement Considerations

Direct substitutes must match the 80-position count, 1.91 mm pitch, and right-angle form factor. Verify that any alternative maintains the MIL-DTL-55302 performance standards. Cross-reference mating interface dimensions to ensure mechanical interchangeability without modifying the PCB footprint.
