RM312-122-121-5900

Headers, Male Pins Overview

The RM312-122-121-5900 is a rectangular MIL-Spec connector from the AirBorn R Series, manufactured by Molex. It is classified as a board mount plug with a straight installation style and features a plastic body constructed from Polyphenylene Sulfide (PPS). The component utilizes a three-row configuration with a pitch of 1.91 mm (0.075 inches) and provides 122 positions. Termination is achieved via through-hole mounting with gold-plated contacts made from beryllium copper and brass. It complies with MIL-DTL-55302 standards and supports an operating temperature range from -65 C to +125 C.

Headers, Male Pins Procurement Notes

Verify current availability directly with Molex or authorized distributors, as this item may be subject to factory special order requirements. Confirm RoHS compliance status, as specific suffixes can alter environmental certifications. Ensure that the ordering suffix matches the exact termination and contact plating requirements for your application. Request official datasheets and ECAD models prior to finalizing design integration to guarantee mechanical fit and electrical compatibility.

Headers, Male Pins Selection Notes

Select this connector when a high-density, board-mount solution meeting MIL-DTL-55302 standards is required. The 122-position capacity suits complex signal routing in constrained spaces. Verify that the through-hole termination method aligns with the PCB manufacturing capabilities. Consider the -65 C to +125 C operating range for extreme environment suitability. Ensure mating receptacles are sourced from the same R Series family to maintain interface integrity.

Headers, Male Pins Part Context

This part belongs to the AirBorn R Series, a line of rectangular connectors designed for harsh environments. The series is widely used in aerospace and defense applications due to its durability and compliance with strict military standards. The RM312 prefix indicates a board mount plug configuration within the broader product portfolio.

Headers, Male Pins Replacement Considerations

Compatible substitutes include other R Series plugs with matching position counts and row configurations, such as RM312-122-121-5500 or RM312-122-121-2900, provided the termination and plating suffixes meet the specific circuit requirements.
