RM372-140-311-5500

Headers, Male Pins Overview

The RM372-140-311-5500 is a rectangular MIL Spec connector from the AirBorn R Series, manufactured by Molex. It functions as a board mount plug with a right-angle orientation and a plastic body. The component features three rows of contacts, providing 140 positions with a 1.91 mm (0.075 inch) pitch. Termination is achieved via through-hole mounting with a 0.109-inch tail length. Contacts are gold-plated beryllium copper or brass pins. The housing utilizes Polyphenylene Sulfide (PPS). It complies with MIL-DTL-55302 standards, operates between -65°C and +125°C, and supports 750 V voltage and 3 A current ratings.

Headers, Male Pins Procurement Notes

Verify the specific manufacturer ordering requirements and lead times directly with Molex or authorized distributors, as this component may be subject to factory special order status. Confirm that the requested quantity matches the minimum order constraints and ensure compatibility with existing PCB footprints. Request updated RoHS certificates and material declarations to verify regulatory compliance for your specific application environment before finalizing procurement.

Headers, Male Pins Selection Notes

Select this part when a right-angle, high-density connection is required for MIL-DTL-55302 applications. Ensure the PCB layout accommodates the 1.91 mm pitch and through-hole tail length. Verify that the 3 A current rating and 750 V insulation withstand voltage meet circuit demands. Consider the PPS housing properties for environmental resistance and confirm that the guide set configuration aligns with mating receptacle requirements.

Headers, Male Pins Part Context

This connector belongs to the AirBorn R Series, a line of high-density rectangular connectors designed for demanding environments. The series offers various row counts and position options, all sharing a consistent 1.91 mm pitch. The RM372-140-311-5500 specifically addresses needs for high pin counts in right-angle board-to-board or cable-to-board configurations within military and aerospace sectors.

Headers, Male Pins Replacement Considerations

Compatible substitutes include other MIL-DTL-55302 compliant connectors with matching 140-position, 3-row, right-angle specifications. Verify cross-reference part numbers from Molex/AirBorn or equivalent manufacturers ensuring identical pitch, termination type, and contact plating. Confirm mechanical dimensions and mounting ear configurations match the original design.
