VSF-04-20-50-03-L

Overview

The AirBorn VSF-04-20-50-03-L is a rectangular MIL-Spec connector from the verSI series, designed for high-density interconnects. It features a 1.27 mm pitch with 4 rows and 20 columns, providing 80 positions. The component utilizes gold-plated beryllium copper contacts housed in a liquid crystal polymer body. Rated for 2 A current and 200 V voltage, it operates between -55 °C and +125 °C. This straight-mount receptacle employs through-hole termination for secure PCB attachment.

Feature Summary

• High-density 1.27 mm pitch architecture supporting 80 circuits in a compact form factor
• Gold-plated beryllium copper contacts ensure reliable signal transmission and corrosion resistance
• Liquid crystal polymer housing provides structural stability and thermal endurance
• Compliance with MIL-DTL-83513 standards for rigorous military-grade performance

Applications

• Military avionics systems requiring verified MIL-Spec reliability
• Ruggedized electronic enclosures demanding high-density interconnects
• Board-to-board stacking applications utilizing vertical receptacle interfaces
• Defense communication equipment operating in extreme temperature environments

Procurement Notes

Verify the specific suffix against official Molex/AirBorn documentation to confirm contact plating thickness and termination style. Confirm RoHS compliance status directly with the manufacturer as environmental declarations may vary by production batch. Ensure the ordering configuration matches the required board thickness and mounting constraints before finalizing procurement.

Selection Notes

Select this part when a straight-mount receptacle interface is required for 4-row configurations. Verify that the 1.27 mm pitch aligns with the mating plug specifications. Confirm that the through-hole termination method suits the target PCB fabrication capabilities. Ensure the liquid crystal polymer material meets the thermal requirements of the intended operational environment.

Part Context

This component belongs to the AirBorn verSI series, which specializes in high-density rectangular connectors. The series supports various termination styles including press-fit and through-hole options. The VSF designation indicates a female receptacle configuration within the broader MIL-DTL-83513 compliant product family.

Replacement Considerations

Consult official cross-reference guides for compatible substitutes. Verify pinout compatibility and mechanical dimensions before substituting. Ensure replacement parts maintain identical MIL-DTL-83513 certification levels.
