VSF-04-50-50-03-L

Overview

The AirBorn VSF-04-50-50-03-L is a rectangular military specification connector from the verSI series, manufactured by Molex. It functions as a receptacle with female sockets and utilizes a through-hole board mount installation style. The component features a plastic body constructed from liquid crystal polymer (LCP) and offers 200 positions arranged in 4 rows. Key electrical parameters include a 1.27 mm pitch, a current rating of 2 A, and an operating temperature range from -55 C to +125 C. The contacts are gold-plated phosphor bronze.

Feature Summary

• High-density interconnect capability with 200 positions in a compact four-row configuration
• Robust construction using liquid crystal polymer housing for thermal stability
• Gold-plated phosphor bronze contacts ensuring reliable signal transmission
• Compliance with MIL-DTL-83513 standards for military-grade durability

Applications

• Military avionics systems requiring high pin count connectivity
• Radar and electronic warfare equipment interfaces
• Ground-based communication infrastructure
• Aerospace control modules demanding strict environmental tolerance

Procurement Notes

Verify the specific suffix 'L' against official Molex/AirBorn documentation to confirm material composition and plating specifications. Ensure compatibility with mating plugs such as the VSM series. Confirm RoHS compliance status via the manufacturer's certificate. Validate that the through-hole termination matches your PCB fabrication capabilities. Check for any recent obsolescence notices or lifecycle changes directly from the supplier.

Selection Notes

Select this component when a high-density, low-profile rectangular connector is required for board-to-board or cable-to-board applications. The plastic body variant is suitable for environments where weight reduction is prioritized over metal shielding. Ensure the mating counterpart shares the same row and column count. Verify that the 2 A current rating per contact meets the circuit load requirements. Consider the fixed jacknut mounting style for secure attachment within specified board thickness limits.

Part Context

This part belongs to the AirBorn verSI series, designed for high-performance military and aerospace applications. The series is known for its small form factor and high I/O density. The VSF designation indicates a receptacle with a plastic body, distinguishing it from metal-bodied variants like the VRF series. The series complies with MIL-DTL-83513, ensuring interoperability with other standard-compliant connectors in defense systems.

Replacement Considerations

Direct substitutes must match the 200-position, 4-row, through-hole configuration. Compatible alternatives within the verSI family include VSF-04-50-50-03-G or VSF-04-50-50-03-N, depending on the required mounting hardware and body material. Verify that any replacement maintains the same 1.27 mm pitch and gold plating specifications to ensure mechanical and electrical compatibility.
