VRM-08-20-100-50-04-L1

Overview

The VRM-08-20-100-50-04-L1 is a rectangular MIL-Spec connector from the AirBorn Versi series, manufactured by Molex. It features a 4-row configuration with 20 columns, providing 80 positions. The connector utilizes through-hole termination for board mounting and employs gold-plated male pins. Designed to meet MIL-DTL-83513 standards, it operates within a temperature range of -55°C to +125°C. The housing is constructed from liquid crystal polymer (LCP), ensuring high insulation resistance and durability in demanding environments.

Feature Summary

• Compliant with MIL-DTL-83513 military specifications for rugged reliability
• Utilizes gold-plated contacts for superior conductivity and corrosion resistance
• Constructed with liquid crystal polymer insulators for thermal stability

Applications

• Military avionics systems requiring verified MIL-Spec interconnects
• Ruggedized backplane connections in defense electronics
• High-density board-to-board stacking applications

Procurement Notes

Verify the specific suffix 'L1' against the official manufacturer datasheet to confirm exact plating thickness and material composition. Ensure compatibility with mating receptacles within the same Versi series family. Confirm that the through-hole termination style matches the target PCB fabrication capabilities. Cross-reference the MIL-DTL-83513 compliance status directly with the source documentation before integration.

Selection Notes

Select this component when a vertical, through-hole MIL-Spec connector is required for high-reliability applications. The 4-row, 20-column layout offers a balanced density for space-constrained designs. Verify that the operating temperature range of -55°C to +125°C meets environmental requirements. Ensure the board spacing and jacknut specifications align with the mechanical assembly constraints.

Part Context

This part belongs to the AirBorn Versi series, a line of rectangular connectors designed for harsh environments. The series is known for its compact size and high contact density while maintaining strict adherence to military standards. The VRM designation typically indicates a plug configuration within this ecosystem, distinguishing it from receptacle or cable variants.

Replacement Considerations

Direct substitutes must match the MIL-DTL-83513 standard, 4-row/20-column geometry, and through-hole termination. Verify pin count and pitch compatibility with existing mating hardware. Generic equivalents may lack the specific environmental ratings or certification required for military-grade applications.
