VRM-04-50-100-50-00-N

Overview

The VRM-04-50-100-50-00-N is a rectangular MIL-DTL-83513 Series connector manufactured by Molex / AirBorn. It is a plug with 200 positions arranged in 4 rows and 50 columns. The component features male pin contacts made of phosphor bronze with gold plating, utilizing a through-hole termination style. The housing is constructed from liquid crystal polymer (LCP). It operates within a temperature range of -55°C to +125°C and supports a current rating of 2 A per contact.

Feature Summary

• Complies with MIL-DTL-83513 military specifications for high-reliability applications
• Utilizes press-fit or through-hole termination options for secure board mounting
• Features gold-plated phosphor bronze contacts for reliable signal transmission
• Constructed with a liquid crystal polymer body for thermal stability

Applications

• Military avionics systems requiring rugged interconnects
• High-density board-to-board connections in defense electronics
• Radar and communication equipment interfaces
• Industrial control systems operating in extreme temperatures

Procurement Notes

Verify the specific termination variant against official datasheets, as suffixes may indicate different mounting styles such as press-fit or through-hole. Confirm RoHS compliance status directly with the manufacturer, as some variants may not meet standard environmental directives. Ensure the selected part matches the required board thickness and spacing specifications for your design integration.

Selection Notes

Select this component when a high-pin-count, MIL-spec rectangular connector is required for vertical board mounting. Consider the LCP material properties for high-temperature environments exceeding standard plastic limits. Evaluate the 2A current rating against system power distribution needs. Verify compatibility with mating receptacles from the same verSI series to ensure proper alignment and electrical continuity.

Part Context

This part belongs to the AirBorn verSI series, designed for high-density interconnects in demanding environments. The series offers various configurations including plugs and receptacles with metal or plastic bodies. The VRM model specifically denotes a plug configuration with a plastic housing, distinguishing it from metal-bodied counterparts like the VRF or VRRAF series.

Replacement Considerations

Direct substitutes include other VRM-04-50-100-50-00-L variants if lead-free certification is required instead of nickel plating. Cross-reference with Molex / AirBorn documentation to confirm equivalent performance characteristics before substitution.
