VSF-04-20-50-04-N1

Overview

The AirBorn VSF-04-20-50-04-N1 is a rectangular MIL-Spec receptacle from the verSI series. It features an 80-position configuration with 4 rows and 20 columns, utilizing a 1.27 mm (0.050 inch) pitch. The component employs a plastic body and vertical through-hole termination with a 0.140-inch tail length. Designed for board-to-board applications, it includes fixed jacknuts suitable for maximum board thicknesses of 0.125 inches. The connector supports a voltage rating of 200 V and operates within a temperature range of -55°C to +125°C.

Feature Summary

• High-speed signal transmission capability inherent to the verSI series design
• Robust mechanical coupling via fixed jackscrew mounting system
• Durable plastic housing construction for lightweight structural integrity

Applications

• Board-to-board interconnects in military avionics systems
• High-density data processing units requiring reliable signal integrity
• Ruggedized electronic enclosures subject to vibration and shock

Procurement Notes

Verify the specific suffix 'N1' against official Molex/AirBorn documentation to confirm material composition and plating specifications. Ensure compatibility with mating plugs regarding row count and pin configuration. Confirm RoHS compliance status if required by project specifications. Cross-reference the fixed jacknut design with panel thickness constraints during integration planning.

Selection Notes

Select this component when high-speed performance and MIL-DTL-83513 compliance are required. The 80-position density suits complex signal routing needs. Verify that the plastic body material meets environmental resistance requirements. Ensure the through-hole termination method aligns with the PCB fabrication capabilities and thermal management strategy of the assembly.

Part Context

This part belongs to the AirBorn verSI family, known for high-speed rectangular connectors. The series is designed to meet stringent military standards while providing compact form factors. The VSF variant specifically denotes a receptacle with a plastic body, distinguishing it from metal-bodied counterparts like the VRF series. This lineage ensures interoperability with other verSI series components.

Replacement Considerations

Direct substitutes include VSF-04-20-50-04-G for gold-plated contacts or VSF-04-20-50-04-N for standard nickel plating. Verify that alternative suffixes match the required contact finish and body material. Ensure mating connectors share the same 4-row, 20-column geometry and 1.27 mm pitch to maintain electrical continuity.
