VRM-04-10-200-50-04-L1

Overview

The VRM-04-10-200-50-04-L1 is a rectangular MIL-Spec connector from the AirBorn verSI series, manufactured by Molex. It features a 4-row configuration with 200 positions and a 1.27 mm pitch. Designed as a plug with male pins, it utilizes through-hole termination for board mounting. The contacts are gold-plated phosphor bronze, housed in a gray liquid crystal polymer (LCP) body. It complies with MIL-DTL-83513 standards, supporting high-speed applications with a voltage rating of 200 V and current capacity of 2 A per contact.

Feature Summary

• Complies with MIL-DTL-83513 military specifications for rugged reliability
• High-density 4-row architecture enabling 200 circuit connections
• Gold-plated phosphor bronze contacts ensure stable signal integrity
• Liquid crystal polymer housing provides thermal stability

Applications

• Avionics systems requiring high pin count interconnects
• Military communication equipment
• Radar and electronic warfare subsystems
• High-speed data transmission backplanes

Procurement Notes

Verify the specific suffix 'L1' against official Molex documentation to confirm plating thickness and material composition. Ensure compatibility with mating receptacles within the same verSI series. Confirm RoHS status and environmental certifications required for the target deployment environment before finalizing procurement.

Selection Notes

Select this component when a high-density, MIL-spec plug is required for board-to-board or cable-to-board interfaces. The 4-row layout maximizes connectivity in constrained spaces. Verify that the mating receptacle supports the 200-position count and matches the 1.27 mm pitch. Consider the LCP housing material for applications involving elevated operating temperatures up to +125 C.

Part Context

This part belongs to the AirBorn verSI family, known for high-performance rectangular connectors. The series offers various row counts and termination styles. The VRM designation indicates a plug configuration. The 200 position count places it in the high-density category of the product line, suitable for complex signal routing in demanding environments.

Replacement Considerations

Direct substitutes include other VRM variants with matching 4-row and 200-position configurations. Ensure any replacement maintains the same MIL-DTL-83513 compliance and physical dimensions. Verify that the mating interface remains compatible with existing system receptacles.
