VRM-04-20-100-50-00-N

Overview

The VRM-04-20-100-50-00-N is a rectangular MIL-DTL-83513 series plug manufactured by Molex / AirBorn. It features a vertical orientation with a press-fit termination style and a metal body construction. The connector supports 4 rows and 20 columns, providing 80 positions for male pin contacts. It utilizes gold-plated phosphor bronze contacts housed in a liquid crystal polymer insulator. Designed for board mounting, it accommodates a 10.00mm board spacing and operates within a temperature range of -55°C to +125°C.

Feature Summary

• Vertical male interface designed for high-density PCB mounting applications
• Press-fit termination ensures secure mechanical connection without soldering
• Metal housing provides robust structural integrity and EMI shielding capabilities

Applications

• Military and aerospace electronic systems requiring MIL-DTL-83513 compliance
• High-reliability telecommunications infrastructure equipment
• Datacom hardware demanding signal integrity and durable board stacking

Procurement Notes

Verify the specific ordering suffix against official AirBorn documentation to confirm exact plating thickness, board thickness compatibility, and jacknut specifications. Ensure the selected variant matches the required press-fit force and termination length for your PCB design. Cross-reference the manufacturer part number with current distributor availability as stock levels may fluctuate.

Selection Notes

Select this component when a vertical, non-soldered interconnection is required for rigid board-to-board or backplane applications. The press-fit option eliminates thermal stress on the PCB during assembly. Confirm that the 10.00mm board spacing aligns with your system's mechanical stack-up requirements and that the metal housing meets environmental protection needs.

Part Context

This part belongs to the AirBorn verSI series, which offers various termination styles including press-fit and through-hole options. The VRM prefix indicates a vertical plug configuration with a metal shell, distinguishing it from plastic-bodied VSM variants. This series is engineered for demanding environments where reliability and signal integrity are critical performance factors.

Replacement Considerations

Compatible substitutes include other MIL-DTL-83513 compliant connectors from qualified manufacturers. Verify dimensional compatibility, particularly the 10.00mm board spacing and 1.27mm pitch. Ensure equivalent contact material and plating specifications are maintained for electrical performance matching.
