VRM-08-40-100-50-03-N

Overview

The VRM-08-40-100-50-03-N is a board stacking connector from the AirBorn verSI series, manufactured by Molex / AirBorn. It features a male interface with 40 columns and 8 rows, providing 320 positions. The connector utilizes a press-fit termination style for vertical PCB mounting. Key electrical ratings include a current capacity of 2 A and a voltage rating of 200 V. The contacts are gold-plated phosphor bronze, housed in a liquid crystal polymer (LCP) body. It operates within a temperature range of -55 C to +125 C.

Feature Summary

• High-density interconnect capability with 320 positions arranged in an 8-row configuration.
• Robust mechanical stability provided by a metal housing and integrated locking jacknuts.
• Signal integrity optimized through precise 1.27 mm pitch design suitable for high-speed applications.

Applications

• Vertical board-to-board stacking in compact electronic assemblies
• High-density signal routing in military and aerospace systems
• Ruggedized mezzanine connections requiring secure mechanical retention

Procurement Notes

Verify the specific suffix codes against the official datasheet to ensure correct termination and housing material specifications. Confirm compliance requirements such as RoHS status directly with the manufacturer or authorized distributors before procurement. Ensure that the ordering information matches the exact part number variant required for your design.

Selection Notes

Select this component when a vertical male interface with press-fit termination is required for high-density board stacking. The 8-row configuration supports significant I/O density within a constrained footprint. Verify that the system environment falls within the specified operating temperature range and that the mechanical constraints align with the connector's dimensions and locking mechanism.

Part Context

This part belongs to the AirBorn verSI series, which specializes in rectangular connectors for demanding environments. The series offers various row counts and termination options to accommodate different board spacing and density requirements. The VRM variant specifically denotes a board stacking plug designed for vertical integration.

Replacement Considerations

Consult the official AirBorn compatibility matrix for verified substitute part numbers. Ensure any replacement maintains the same pin count, pitch, and termination style to guarantee mechanical and electrical interoperability without redesigning the host assembly.
