10127820-0421LF

Overview

The Amphenol ICC (FCI) part number 10127820-0421LF is a Minitek Power 4.2 series board-to-board connector header. It features a vertical surface-mount termination with a 4.2 mm pitch and four positions in a dual-row configuration. The contacts are constructed from brass and finished with gold plating to ensure reliable conductivity. Designed for power distribution applications, this component supports a current rating of 9 A and operates within a temperature range of -40°C to +105°C. The housing is made of natural liquid crystal polymer (LCP), providing high insulation resistance and mechanical stability for robust electronic assemblies.

Feature Summary

• Vertical surface-mount design for direct PCB integration
• High current capacity suitable for power distribution systems
• Gold-plated brass contacts for enhanced conductivity and corrosion resistance
• Natural LCP insulator offering high thermal stability and insulation

Applications

• Power distribution in industrial equipment
• Server and storage device internal connections
• Communication infrastructure hardware
• Factory automation control boards

Procurement Notes

Verify the specific ordering suffix and environmental compliance status directly with the manufacturer or authorized distributors before purchase. Confirm that the selected variant matches the required pin count and pitch specifications for your circuit design. Ensure compatibility with mating receptacles from the same Minitek Power 4.2 family to maintain proper alignment and electrical performance during assembly.

Selection Notes

Select this connector when a vertical, high-current board-to-board interface is required. The 4.2 mm pitch allows for wider contact spacing compared to signal connectors, supporting higher amperage loads. Consider the natural LCP material for applications requiring resistance to soldering heat and chemical exposure. Verify that the dual-row layout fits within the available board space constraints.

Part Context

This component belongs to the Minitek Power series by Amphenol ICC (FCI), a line specialized in power delivery solutions. The series is engineered for demanding environments, offering durability against vibration and temperature fluctuations. It complements other FCI interconnect products used in data processing and telecommunications, providing standardized interfaces for efficient system integration and maintenance.

Replacement Considerations

Consult official substitution lists for compatible headers within the Minitek Power 4.2 family. Ensure any alternative part maintains identical pitch, row configuration, and current ratings. Verify that mounting dimensions and locking mechanisms match the existing design to avoid rework.
