10127820-2422LF

Overview

The Amphenol ICC (FCI) part number 10127820-2422LF is a Minitek Power4.2 series power connector designed for board-to-board applications. It features a double row of 24 positions with a 4.2 mm pitch. The header utilizes brass contacts with a tin plating finish and is rated for 9 A current. Designed for through-hole vertical mounting, it operates within a temperature range of -40°C to +105°C and maintains an insulation resistance of 1 GOhms.

Feature Summary

• Supports high-current power distribution via a 9 A rating per contact
• Provides secure mechanical retention through through-hole solder termination
• Ensures reliable electrical performance with specified insulation resistance

Applications

• Power delivery in industrial control systems
• Power interfaces in telecommunications equipment
• Power connections in automotive electronics

Procurement Notes

Verify the specific contact plating configuration against project requirements, as this part number specifies tin plating which differs from gold-plated variants in the same series. Confirm that the 4.2 mm pitch and 24-position count align with the target PCB footprint. Ensure the through-hole vertical mounting style matches the assembly process capabilities. Cross-reference the 9 A current rating with the actual thermal environment to prevent overheating during operation.

Selection Notes

Select this component when a robust, high-current power interface is required for vertical board stacking. The 4.2 mm pitch allows for wider trace spacing compared to signal connectors, reducing short-circuit risks. The tin plating offers cost-effective conductivity suitable for environments where frequent mating cycles are not expected. Consider the operating temperature range to ensure compatibility with the system's thermal profile.

Part Context

This connector belongs to the Minitek Power4.2 family, engineered for demanding power transmission scenarios. The series provides standardized dimensions for easy integration into various electronic assemblies. As a vertical header, it facilitates efficient space utilization on printed circuit boards while maintaining structural integrity under mechanical stress.

Replacement Considerations

Compatible substitutes include 10127820-1824LCLF and 10127820-2224GLF, though these differ in position count or plating material. Verify that alternative parts match the 4.2 mm pitch and 9 A rating before implementation.
