VRM-04-50-100-50-06-L1

Overview

The VRM-04-50-100-50-06-L1 is a rectangular MIL-Spec connector from the AirBorn verSI series, manufactured by Molex. It features a 200-position configuration with 4 rows and male pin contacts. The component utilizes a through-hole termination method for board mounting. Contact plating is gold over phosphor bronze, ensuring reliable conductivity. The housing material is liquid crystal polymer (LCP), providing thermal stability within an operating temperature range of -55°C to +125°C. The contact pitch is 1.27 mm, and it complies with MIL-DTL-83513 standards.

Feature Summary

• High-density interconnect capability with 200 positions in a compact 4-row layout
• Robust construction using liquid crystal polymer housing for high-temperature resistance
• Gold-plated phosphor bronze contacts for superior signal integrity and corrosion resistance
• Compliance with MIL-DTL-83513 military specifications for rugged environments

Applications

• Military avionics systems requiring high-pin-count interconnects
• Ruggedized ground-based communication equipment
• Aerospace data processing units
• Defense electronics platforms

Procurement Notes

Verify the specific suffix 'L1' against the official Molex/AirBorn datasheet to confirm exact housing material and termination details, as suffixes often denote critical variations. Ensure compatibility with mating receptacles from the same verSI series. Confirm RoHS status and lead times directly with authorized distributors, as availability may vary for specialized military-grade components.

Selection Notes

Select this part when a high-density, MIL-Spec compliant plug is required for board-to-board or cable-to-board connections. The 1.27 mm pitch allows for significant I/O density in constrained spaces. Consider the LCP housing if operation exceeds standard plastic limits. Verify that the mating receptacle supports the 200-position count and matches the through-hole termination style.

Part Context

This component belongs to the AirBorn verSI series, designed for high-performance applications. The series is known for its small form factor and reliability under harsh conditions. The VRM designation indicates a plug configuration, while the numeric codes define the row, column, and tail length specifications. It is part of Molex's portfolio of specialized interconnect solutions.

Replacement Considerations

Direct replacements must match the 200-position count, 4-row layout, and 1.27 mm pitch. Verify that any substitute part shares the MIL-DTL-83513 compliance and similar electrical ratings. Cross-referencing with other manufacturers requires careful validation of mechanical dimensions and contact plating specifications to ensure interchangeability.
