VSF-04-20-50-04-L1

Overview

The AirBorn VSF-04-20-50-04-L1 is a rectangular MIL-Spec receptacle from the verSI series, compliant with MIL-DTL-83513. It features a 1.27 mm pitch and a plastic body constructed from Liquid Crystal Polymer (LCP). The connector provides 80 positions arranged in 4 rows of 20 columns, utilizing gold-plated beryllium copper female sockets. Designed for vertical through-hole board mounting with a 0.140-inch tail length, it includes fixed jacknuts for boards up to 0.125 inches thick. Rated for 2 A current and 200 V voltage, it operates between -55°C and +125°C with an insulation resistance of 5 GOhms.

Feature Summary

• Compliant with MIL-DTL-83513 military specifications for rugged reliability
• Utilizes high-density 1.27 mm pitch for compact circuit integration
• Features LCP plastic housing for thermal stability and durability
• Includes fixed jacknuts for simplified installation on standard thickness boards

Applications

• Vertical PCB mounting in defense avionics systems
• High-density interconnects in military communication equipment
• Ruggedized electronic modules requiring MIL-Spec compliance

Procurement Notes

Verify the specific suffix codes against official Molex/AirBorn documentation to ensure correct termination style and contact plating. Confirm that the fixed jacknut configuration matches the target board thickness constraints. Cross-reference the latest datasheet revision to validate environmental ratings and material compositions before finalizing procurement orders.

Selection Notes

Select this component when a MIL-DTL-83513 compliant receptacle with a plastic body is required for vertical through-hole assembly. Ensure the design accommodates the 0.140-inch tail length and utilizes fixed jacknuts suitable for boards up to 0.125 inches thick. Verify that the 1.27 mm pitch aligns with the mating header requirements and that the 2 A current rating meets the circuit load demands.

Part Context

This part belongs to the AirBorn verSI series, which offers high-density interconnect solutions in both plastic and metal body configurations. The VSF designation indicates a plastic body receptacle within the MIL-DTL-83513 family. This series is engineered for demanding environments where space efficiency and robust mechanical performance are critical for signal integrity and power distribution.

Replacement Considerations

Consult official cross-reference guides for equivalent MIL-DTL-83513 connectors. Verify compatibility regarding pinout, row/column count, and termination method before substituting.
