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

Overview

The VRM-04-50-200-50-04-L1 is a rectangular military specification connector from the AirBorn verSI series, manufactured by Molex. It functions as a plug with 200 positions arranged in four rows and fifty columns. The component utilizes through-hole termination for board mounting and features male pin contacts. Designed to MIL-DTL-83513 standards, it incorporates a metal body construction and operates at a 0.050-inch (1.27mm) pitch.

Feature Summary

• Compliant with MIL-DTL-83513 military specifications for rugged interconnection
• Constructed with a durable metal housing for structural integrity
• Features gold-plated male pin contacts for reliable signal transmission
• Supports high-density circuitry via a 200-position, four-row configuration

Applications

• Military avionics systems requiring standardized interconnects
• Ruggedized ground-based communication equipment
• High-reliability aerospace data processing units
• Defense electronics subject to strict environmental standards

Procurement Notes

Verify the specific suffix L1 against the manufacturer's current datasheet to confirm exact plating thickness and material composition variations. Ensure compatibility with mating receptacles within the same verSI series. Confirm that the through-hole termination method aligns with the target PCB fabrication capabilities. Validate that the metal body dimensions fit the designated enclosure constraints.

Selection Notes

Select this component when MIL-DTL-83513 compliance is mandatory for the application environment. Choose this model for applications requiring a metal housing over plastic alternatives for enhanced shielding or mechanical strength. Ensure the 200-pin count matches the system design requirements. Verify that the straight board mount orientation fits the assembly layout.

Part Context

This part belongs to the AirBorn verSI family of connectors, which are widely used in defense and aerospace sectors. The series is characterized by its small form factor and high contact density. The VRM designation specifically identifies the unit as a plug variant within the broader rectangular connector portfolio.

Replacement Considerations

Direct substitutes must match the MIL-DTL-83513 standard and physical footprint. Compatible replacements include other manufacturers' versions of the same military specification connector. Verify that any alternative maintains the 200-position count and 0.050-inch pitch to ensure interchangeability.
