10127820-0421LCLF

Overview

The Amphenol ICC (FCI) part number 10127820-0421LCLF is a Minitek Power 4.2 series vertical through-hole header connector designed for power-to-board applications. It features a 4-position configuration with a 4.2 mm pitch and double-row arrangement. The contacts are made of brass with gold plating, rated for 9 A current at +105°C maximum operating temperature. The housing is natural liquid crystal polymer (LCP), providing high insulation resistance of 1 GOhm. This component supports reliable electrical connections in compact, power-dense environments.

Feature Summary

• Vertical through-hole mounting design for direct board integration
• Gold-plated brass contacts ensure stable conductivity and corrosion resistance
• Liquid crystal polymer insulator offers high thermal stability and insulation performance

Applications

• Power distribution modules in server infrastructure
• High-density power supply units
• Industrial control system backplanes

Procurement Notes

Verify the specific ordering suffix to confirm contact plating thickness and packaging type. Ensure compatibility with mating socket components within the same Minitek Power 4.2 series. Confirm that the vertical header orientation matches the mechanical constraints of the target assembly. Cross-reference the manufacturer datasheet for precise dimensional tolerances before finalizing procurement specifications.

Selection Notes

Select this connector when a low-profile, high-current vertical interface is required. The 4.2 mm pitch allows for robust power handling while maintaining a compact footprint. Consider the double-row layout for increased pin density compared to single-row alternatives. Verify that the LCP material properties meet the thermal requirements of the operational environment.

Part Context

This component belongs to the Minitek Power 4.2 family, a line of high-density connectors by Amphenol FCI. The series is engineered for applications demanding reliable power transmission in space-constrained designs. It complements other variants in the lineup that offer different position counts and pitch options, ensuring modular scalability for various power management needs.

Replacement Considerations

Direct substitutes include other 4-position, 4.2mm pitch vertical headers from the same Minitek Power 4.2 series, such as 10127820-0421TLF or 10127820-0421LPCLF, provided the contact plating and packaging match the original specification.
