VSM-05-20-080-50-04-L1

Overview

The VSM-05-20-080-50-04-L1 is a vertical male board stacking connector from the AirBorn verSI series. It features a 1.27 mm pitch and comprises 5 rows with 20 columns, providing 100 positions. The unit utilizes through-hole termination style 04 (PTH 0.140") and includes a locking jacknut option L1. Designed for MIL-DTL-83513 compliance, it employs gold-plated phosphor bronze contacts within an LCP housing, rated for 2 A current at 200 V.

Feature Summary

• Vertical male interface designed for high-density PCB stacking applications
• Signal-integrity optimized construction for reliable data transmission
• MIL-DTL-83513 compliant ruggedized rectangular connector design

Applications

• Military aerospace avionics systems
• High-reliability electronic equipment
• Board-to-board interconnects in harsh environments

Procurement Notes

Verify the specific termination tail length and locking mechanism configuration against the engineering drawing before procurement. Confirm that the L1 locking jacknut option matches the assembly requirements. Ensure the manufacturer's latest revision of the datasheet is consulted to validate all dimensional parameters prior to finalizing the purchase order.

Selection Notes

Select this component when a vertical male connection is required for rigid board stacking. The 1.27 mm pitch supports high I/O density. Verify that the 0.140" PTH termination fits the target PCB thickness. Ensure the operating temperature range of -55 C to +125 C meets the environmental specifications of the intended application.

Part Context

This part belongs to the AirBorn verSI series, which provides signal-integrity connectors for vertical PCB mounting. The series offers various row and column configurations with multiple termination styles including press-fit and surface mount. The VSM designation indicates a vertical male interface, while the suffixes define specific plating, spacing, and mechanical options.

Replacement Considerations

No direct public substitute part numbers are confirmed. Cross-reference with other Molex/AirBorn VSM variants only if they match the exact 1.27 mm pitch, 5x20 configuration, and PTH 0.140" termination.
