VRF-08-40-50-03-L

Overview

The VRF-08-40-50-03-L is a rectangular MIL-DTL-83513 receptacle from the AirBorn verSI series, manufactured by Molex. It features 320 positions arranged in 8 rows and 40 columns with a 1.27 mm pitch. The connector utilizes gold-plated beryllium copper sockets for reliable signal transmission. Designed for board mount applications, it employs a through-hole termination style with a straight installation angle. The housing is constructed from aluminum alloy, providing durability in demanding environments. It operates within a temperature range of -55°C to +125°C and supports up to 200 V voltage.

Feature Summary

• Compliant with MIL-DTL-83513 military specifications for high-reliability interconnects
• Features a robust aluminum alloy shell for structural integrity and shielding
• Utilizes gold-plated contacts to ensure low contact resistance and corrosion resistance
• Designed for vertical board mounting with fixed jacknuts for secure attachment

Applications

• Military avionics systems requiring high-density interconnects
• Radar and electronic warfare equipment
• Ground-based communication infrastructure
• Aerospace control modules

Procurement Notes

Verify the specific suffix 'L' against official Molex documentation to confirm material or plating variations compared to standard 'N' versions. Confirm RoHS compliance status via current certificates as manufacturing processes may evolve. Ensure compatibility with mating plugs such as the VSF series before procurement. Request updated datasheets to verify any recent Product Change Notifications (PCNs) affecting dimensions or materials.

Selection Notes

Select this component when a high-pin-count, ruggedized connector is required for vertical PCB integration. The 320-position capacity suits complex signal routing needs. Ensure the mating plug matches the 8-row, 40-column configuration. Verify that the board thickness accommodates the fixed jacknut design. Consider thermal management requirements given the 125°C maximum operating temperature limit.

Part Context

This part belongs to the AirBorn verSI series, known for high-speed performance and reliability in harsh environments. The series is widely used in defense and aerospace sectors where vibration resistance and signal integrity are critical. As a Molex product, it benefits from established supply chain support and rigorous quality control standards associated with military-grade connectors.

Replacement Considerations

Direct substitutes include other MIL-DTL-83513 compliant receptacles with identical pin counts and row/column configurations. Cross-reference with Molex/AirBorn internal cross-reference guides for equivalent part numbers. Ensure any replacement maintains the same 1.27 mm pitch and aluminum housing material to preserve mechanical fit and environmental sealing characteristics.
