10127819-18321LF

Overview

The Amphenol ICC (FCI) part number 10127819-18321LF is a Minitek Pwr 4.2 series power connector designed for board-to-board applications. It features an 18-position configuration with a 4.2 mm pitch and supports a current rating of 9 A. The component utilizes brass contacts with gold plating, ensuring reliable conductivity. It is constructed as a right-angle header with two rows, suitable for surface mounting or through-hole integration depending on the specific variant requirements. The housing is made from natural-colored insulating material, providing stability within an operating temperature range of -40°C to +105°C.

Feature Summary

• High-current capability with a 9 A rating per contact for robust power distribution.
• Gold-plated brass contacts ensure low contact resistance and corrosion resistance.
• Right-angle design facilitates compact vertical space optimization in dense assemblies.

Applications

• Server and storage equipment power distribution systems
• Industrial control boards requiring high current density
• Telecommunications infrastructure power modules

Procurement Notes

Verify the exact suffix and plating specifications against the official datasheet before ordering, as variations exist within the Minitek Pwr 4.2 family. Confirm availability status directly with the manufacturer or authorized distributors, as lead times may vary for factory special orders. Ensure that the selected variant matches the required mounting style and contact orientation for your specific PCB layout constraints.

Selection Notes

Select this component when a high-current, right-angle power connection is required in a limited vertical space. The 4.2 mm pitch allows for substantial conductor sizing compared to smaller signal connectors. Consider the thermal management capabilities of the PCB and the mating connector to ensure the 9 A rating is not exceeded under continuous load conditions. Verify insulation resistance and flammability ratings meet the safety standards of the target application environment.

Part Context

This connector belongs to the Minitek Pwr 4.2 series by Amphenol ICC (FCI), a line specialized for power delivery in electronic systems. The series is known for its durability and ability to handle significant electrical loads in demanding environments. It complements other FCI solutions like the SFYL and Aorora lines, which focus on signal and flexible flat cable connections, offering a comprehensive portfolio for mixed-signal board designs.

Replacement Considerations

Direct substitutes must match the 4.2 mm pitch, 18-position count, and right-angle form factor. Check for equivalent gold-plated brass contacts and identical current ratings. Verify mechanical compatibility with mating sockets and PCB footprint dimensions to ensure seamless integration without redesigning the host board.
