VSM-05-50-100-50-04-L1

Overview

The VSM-05-50-100-50-04-L1 is a rectangular military specification connector from the AirBorn verSI series, manufactured by Molex. It features a 0.050-inch (1.27mm) pitch with a plastic body and vertical orientation. This plug variant provides 250 positions arranged in 5 rows of 50 columns. The termination method is through-hole with a 0.140-inch tail length, designed for a 10.00mm board spacing. It includes fixed jacknuts for secure mounting on boards up to 0.125 inches thick. The contacts are gold-plated phosphor bronze pins rated for 2A current at 200V, operating within a temperature range of -55°C to +125°C.

Feature Summary

• Military-grade construction compliant with MIL-DTL-83513 standards for rugged environments
• High-density interconnect capability with 250 circuits in a compact vertical form factor
• Secure mechanical attachment using fixed jacknuts compatible with standard board thicknesses
• Durable liquid crystal polymer housing providing thermal stability and chemical resistance

Applications

• Avionics systems requiring high-reliability signal transmission
• Radar and electronic warfare equipment interfaces
• Ground-based military communication hardware
• Defense electronics modules demanding strict environmental compliance

Procurement Notes

Verify the specific suffix 'L1' against the manufacturer's latest datasheet to confirm plating thickness and termination tail length specifications. Ensure compatibility with mating receptacles such as VRRAF series components. Confirm RoHS status and material declarations prior to integration into regulated assemblies.

Selection Notes

Select this component when a vertical, high-pin-count solution is required for PCB stacking or panel mounting. The 0.050-inch pitch allows for dense circuit routing while maintaining reliable contact performance. Consider the through-hole termination for robust mechanical anchoring compared to surface mount alternatives.

Part Context

This part belongs to the AirBorn verSI family of rectangular connectors, known for their small form factor and high density. The series supports various termination styles including press-fit and through-hole options. It is widely used in aerospace and defense applications where space constraints and reliability are critical design factors.

Replacement Considerations

Direct substitutes may include other MIL-DTL-83513 compliant connectors with matching 5-row, 50-column configurations. Verify pinout compatibility and board spacing dimensions before substitution. Consult Molex/AirBorn engineering for approved alternate part numbers.
