RM452-196-321-9503

Headers, Male Pins Overview

The AirBorn RM452-196-321-9503 is a rectangular MIL-DTL-55302 board mount plug from the R Series. It features a right-angle installation style with a plastic body and 196 positions arranged in four rows. The connector utilizes a 1.91 mm pitch and through-hole termination for secure PCB mounting. Gold-plated beryllium copper contacts ensure reliable signal transmission, while the polyphenylene sulfide housing provides thermal stability. Rated for 750 V and 3 A, it operates within a temperature range of -65°C to +125°C.

Headers, Male Pins Procurement Notes

Verify the specific polarization code and guide pin configuration against the design requirements before procurement. Confirm that the supplier source is authorized to handle AirBorn/Molex products to ensure component authenticity. Check for any recent manufacturing updates or lifecycle status changes directly with the manufacturer. Ensure storage conditions comply with moisture sensitivity levels if applicable. Validate that the right-angle orientation matches the mechanical constraints of the target assembly.

Headers, Male Pins Selection Notes

Select this model when a 196-position, four-row connector is required for space-constrained right-angle layouts. The 1.91 mm pitch offers a balance between density and manufacturability. Consider the gold plating option for environments where contact resistance stability is critical over long service lives. The PPS housing allows for higher operating temperatures compared to standard thermoplastics. Evaluate the through-hole mounting ears for mechanical stress relief needs.

Headers, Male Pins Part Context

This component belongs to the AirBorn R Series, a family of rectangular connectors designed for harsh environments. The series is known for its modular design and compliance with stringent military standards. The RM452 prefix indicates a specific housing size and configuration within the broader product line. Molex acquired AirBorn, integrating these specialized connectors into their industrial portfolio.

Headers, Male Pins Replacement Considerations

Direct substitutes must match the MIL-DTL-55302 specification, 196 position count, and 1.91 mm pitch. Verify compatibility of mating shell parts and guide pin arrangements. Cross-reference electrical ratings and housing materials to ensure equivalent performance in the application environment.
