RM652-604-321-9501

Headers, Male Pins Overview

The RM652-604-321-9501 is a rectangular MIL Spec connector from the AirBorn R Series, manufactured by Molex. It is a board mount plug with a right-angle orientation and a plastic body. The component features six rows of contacts with a pitch of 1.91 mm (0.075 inches). It supports 604 circuits and utilizes through-hole termination. The housing is constructed from Polyphenylene Sulfide (PPS), rated for operation between -65°C and +125°C. Contacts are made of Beryllium Copper and Brass with gold plating, rated at 3 A current and 750 V voltage. It includes guide pins and mounting ears.

Headers, Male Pins Procurement Notes

Verify the specific suffix codes against the official Molex/AirBorn datasheet to ensure exact configuration matching. Confirm that the gold termination and through-hole style align with the target PCB assembly requirements. Check RoHS compliance status as indicated in manufacturer documentation, noting potential restrictions for certain military variants. Ensure availability of mating connectors within the same R Series family.

Headers, Male Pins Selection Notes

Select this model when high-density interconnects are required in constrained spatial layouts due to its right-angle form factor. The 604-circuit capacity suits complex signal routing needs. Verify that the 1.91 mm pitch accommodates the available board trace spacing. Consider the PPS material properties if high-temperature soldering processes or elevated operating environments are anticipated.

Headers, Male Pins Part Context

This component belongs to the AirBorn R Series, a line of rectangular connectors designed for harsh environments. The series is known for strict adherence to MIL-C-55302 standards. AirBorn, now part of Molex, specializes in connectors for defense and aerospace applications, providing solutions for critical mission-critical systems requiring high durability and signal integrity.

Headers, Male Pins Replacement Considerations

Direct substitutes must match the MIL-DTL-55302 standard, 6-row configuration, 1.91 mm pitch, and 604 circuit count. Cross-reference with other R Series variants having identical mounting ear configurations and polarization settings. Ensure any alternative maintains the same right-angle orientation and through-hole termination style.
