VRF-10-20-50-04-L1

Overview

The VRF-10-20-50-04-L1 is a rectangular MIL-DTL-83513 Series receptacle manufactured by AirBorn, a Molex company. It features a 0.050-inch (1.27mm) pitch with a metal body and vertical through-hole termination. The connector provides 200 positions arranged in 10 rows and 20 columns. Contact plating is gold over beryllium copper. It operates within a temperature range of -55°C to +125°C, supports 200VAC voltage rating, and carries a 2A current rating per contact.

Feature Summary

• Compliant with MIL-DTL-83513 military specifications for high reliability
• Utilizes a robust aluminum alloy metal housing for structural integrity
• Features gold-plated beryllium copper female sockets for low resistance
• Designed for vertical board mount via through-hole soldering

Applications

• Military avionics systems requiring high-density interconnects
• Radar and electronic warfare equipment
• Communications infrastructure
• Test and measurement instrumentation

Procurement Notes

Verify the specific suffix L1 against official datasheets to confirm locking mechanism details. Ensure compatibility with corresponding plug assemblies from the same series. Confirm RoHS compliance status if required for specific environmental regulations. Cross-reference part numbers with authorized distributors to avoid counterfeit components.

Selection Notes

Select this component when high pin count density is required in a compact form factor. The 0.050-inch pitch allows for significant circuit routing in limited space. Verify that the board thickness accommodates the tail length and mounting hardware. Consider thermal management requirements given the 2A current rating per contact.

Part Context

This part belongs to the AirBorn verSI series, designed for demanding environments. It complements other receptacles like VRF-04-10-50-04-G but offers higher density. The series is known for durability and consistent performance in harsh conditions, serving as a critical interface in complex electronic assemblies.

Replacement Considerations

Direct substitutes include other MIL-DTL-83513 connectors with identical row/column counts. Verify mating dimensions and shell size compatibility. Alternative manufacturers may offer equivalent specs, but mechanical fit must be confirmed.
