VSF-08-50-50-04-L1

Overview

The VSF-08-50-50-04-L1 is a rectangular MIL Spec connector from the AirBorn verSI series, manufactured by Molex. It functions as a receptacle with female sockets, designed for board mount applications using through-hole termination. The component features an 80-position configuration arranged in 4 rows and 20 columns, utilizing a 1.27 mm pitch. Constructed with a plastic body, it supports vertical installation with a specified tail length of 0.140 inches. The design incorporates fixed jacknuts to accommodate a maximum board thickness of 0.125 inches, ensuring secure mechanical attachment in high-reliability environments.

Feature Summary

• Rectangular military specification construction for high reliability
• Female socket contacts for secure mating engagement
• Through-hole termination for robust board mounting
• Fixed jacknut design for standardized board thickness compatibility

Applications

• Backplane interconnect systems
• High-speed data transmission modules
• Military and aerospace electronic assemblies

Procurement Notes

Verify the specific suffix 'L1' against official Molex/AirBorn documentation to confirm material or plating variations compared to standard 'N' variants. Ensure the requested quantity aligns with special order requirements if not listed as standard stock. Cross-reference the datasheet revision date to confirm current manufacturing status and any recent product change notifications affecting lead times or specifications.

Selection Notes

Select this part when a 4-row, 80-position receptacle is required for vertical board-to-board or backplane connections. Confirm that the 1.27 mm pitch matches the mating plug dimensions. Verify that the through-hole termination method is compatible with the PCB fabrication capabilities. Ensure the fixed jacknut constraint fits within the available chassis depth and board thickness tolerances of the assembly.

Part Context

This component belongs to the AirBorn verSI family, which provides high-density interconnect solutions compliant with MIL-DTL-83513 standards. The series is engineered for demanding environments requiring consistent signal integrity and mechanical durability. As a receptacle, it pairs with corresponding plugs to form complete connector assemblies used in critical communication and control systems.

Replacement Considerations

Direct substitutes include other verSI series receptacles with identical row/column counts and pitch, such as VSF-08-50-50-04-N, provided the termination and housing material suffixes match the application requirements. Verify pinout and contact orientation before substitution.
