VRM-04-50-100-50-04-L1

Overview

The VRM-04-50-100-50-04-L1 is a rectangular MIL-DTL-83513 connector from the AirBorn verSI series, manufactured by Molex. It features a 200-position configuration with four rows and fifty columns. The component utilizes gold-plated phosphor bronze contacts and a liquid crystal polymer (LCP) plastic body. Designed for board mount applications, it employs a through-hole termination style with a straight orientation. The connector supports a maximum operating temperature of +125°C and a minimum of -55°C, rated for 200 V and 2 A per contact.

Feature Summary

• Compliant with MIL-DTL-83513 military specifications for high-reliability interconnection
• Utilizes gold-plated phosphor bronze contacts for corrosion resistance and conductivity
• Constructed with a liquid crystal polymer (LCP) insulator for thermal stability
• Features a 200-position layout arranged in a 4-row by 50-column matrix

Applications

• Board-to-board interconnection in rugged environments
• Military and aerospace electronic systems requiring MIL-Spec reliability
• High-density signal routing on printed circuit boards

Procurement Notes

Verify the specific suffix 'L1' against the manufacturer's current datasheet to confirm plating thickness or material variations. Ensure compatibility with mating receptacles within the same verSI series. Confirm RoHS compliance status as required by your assembly standards. Validate that the through-hole termination method matches your PCB fabrication capabilities.

Selection Notes

Select this part when a 200-contact, 4-row male plug is required for vertical board mounting. The 1.27 mm pitch allows for high density while maintaining standard spacing. The LCP body offers superior heat resistance compared to standard thermoplastics. Ensure the mating interface provides sufficient retention force for the specified vibration environments.

Part Context

This component belongs to the AirBorn verSI family of rectangular connectors, which are designed for demanding industrial and defense applications. The series is characterized by its small form factor and robust mechanical performance. The VRM designation indicates a male plug configuration within this standardized lineup.

Replacement Considerations

Direct substitutes must match the 200-position count, 4-row structure, and 1.27 mm pitch. Verify that any alternative maintains the same MIL-DTL-83513 compliance and through-hole termination style. Cross-reference the housing material and contact plating to ensure environmental compatibility.
