RM452-110-321-9501

Headers, Male Pins Overview

The RM452-110-321-9501 is a rectangular MIL-spec connector from the AirBorn R Series, manufactured by Molex. It features a board mount plug configuration with a right-angle orientation and a plastic body constructed from Polyphenylene Sulfide (PPS). The component provides 110 positions across four rows with a 1.91 mm pitch. It utilizes through-hole termination for male pin contacts made of Beryllium Copper and Brass, finished with Gold plating. Rated for 3 A current and 750 V voltage, it operates within a temperature range of -65 C to +125 C and complies with MIL-DTL-55302 standards.

Headers, Male Pins Procurement Notes

Verify the specific manufacturer lot code and date code upon receipt to ensure compliance with project timelines. Confirm that the received units match the exact part number RM452-110-321-9501, as suffix variations may indicate different termination or polarization options. Request a Certificate of Conformance to validate MIL-DTL-55302 compliance before integration into critical assemblies.

Headers, Male Pins Selection Notes

Select this component when a right-angle, through-hole rectangular connector with 110 circuits is required. Ensure the PCB layout accommodates the 1.91 mm pitch and right-angle profile. Verify that the operating environment stays within the -65 C to +125 C range. Confirm that the 3 A current rating per contact is sufficient for the intended signal or power loads in the application.

Headers, Male Pins Part Context

This connector belongs to the AirBorn R Series, designed for high-reliability applications in harsh environments. The series offers various row counts and circuit densities while maintaining strict adherence to military standards. The RM452 variant specifically denotes a four-row configuration, providing a balance between density and mechanical robustness for board-to-board or cable-to-board connections.

Headers, Male Pins Replacement Considerations

Direct substitutes must share the same MIL-DTL-55302 standard, 110 position count, 4-row layout, and right-angle through-hole termination. Cross-reference with other manufacturers offering equivalent rectangular MIL-spec plugs only if they guarantee identical mating dimensions and electrical ratings.
