10127721-206LF

Overview

The Amphenol ICC (FCI) 10127721-206LF is a Minitek Power3.0 series header connector designed for power-to-board applications. It features a double row configuration with 20 positions and a 3 mm pitch. The component utilizes male pin contacts made of copper with tin plating, rated for 8.5 A current and 600 VAC voltage. Designed for through-hole vertical mounting, it operates within a temperature range of -40°C to +105°C. The housing is constructed from natural liquid crystal polymer (LCP), providing high insulation resistance of 1 GOhms.

Feature Summary

• Double-row vertical header design for board-level power distribution
• Tin-plated copper contacts ensure reliable electrical conductivity
• Liquid crystal polymer housing offers thermal stability and insulation

Applications

• Server and storage equipment power connections
• Telecommunications infrastructure power distribution
• Industrial control system board interconnects

Procurement Notes

Verify the specific contact plating finish upon ordering, as suffixes such as LF or NPLF may indicate variations in terminal material between tin and gold. Confirm that the vertical through-hole package aligns with your PCB assembly requirements. Ensure the 3 mm pitch matches your layout constraints. Cross-reference the manufacturer part number directly with official Amphenol documentation to confirm current availability and lead times before finalizing procurement plans.

Selection Notes

Select this component when a robust, high-current power connection is required in a compact vertical form factor. The 3 mm pitch allows for higher current capacity compared to finer pitches while maintaining standard spacing. Consider the tin plating for cost-effective general-purpose power applications where extreme corrosion resistance is not the primary driver. Verify that the 8.5 A rating per contact meets the total load requirements of the target circuit design.

Part Context

This connector belongs to the Minitek Power3.0 family, engineered for demanding power delivery environments. The series is characterized by its durability and ability to withstand harsh conditions, including high temperatures and vibration. It serves as a critical interface in systems requiring reliable power transmission between boards, supporting the structural and electrical integrity of modern electronic assemblies.

Replacement Considerations

Compatible alternatives within the same series include 10127721-206NPLF, which differs primarily in contact plating material. Other variants in the 10127721 series offer different position counts but maintain the same 3 mm pitch and mechanical footprint. Always verify electrical ratings and physical dimensions before substituting.
