10127721-181LF

Overview

The Amphenol ICC (FCI) 10127721-181LF is a Minitek Pwr 3.0 series power-to-board header connector designed for vertical through-hole mounting. It features a dual-row configuration with 18 positions and a 3mm pitch. The male pins are constructed from copper alloy with gold plating, rated for 8.5 A current and 600 VAC voltage. The housing utilizes natural liquid crystal polymer (LCP), offering an operating temperature range of -40°C to +105°C and UL94 V-0 flammability rating.

Feature Summary

• Dual-row vertical header design for high-density power distribution
• Gold-plated copper alloy contacts ensure reliable conductivity and corrosion resistance
• Liquid crystal polymer insulation provides high thermal stability and flame retardancy

Applications

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

Procurement Notes

Verify the specific suffix requirements against official Amphenol documentation to ensure correct contact plating thickness and material specifications. Confirm availability status directly with authorized distributors as lead times may vary. Ensure compatibility with mating socket connectors within the same Minitek Pwr 3.0 family before finalizing procurement orders.

Selection Notes

Select this component when a vertical, dual-row power connection is required with a 3mm spacing. The 18-position count suits applications needing balanced power and ground routing in compact footprints. Verify that the PCB layout supports through-hole soldering and that the 600VAC rating meets the system's electrical isolation requirements.

Part Context

This part belongs to the Minitek Pwr 3.0 family, a standardized line of power connectors by Amphenol FCI. The series is engineered for robust performance in demanding environments, featuring consistent dimensional tolerances across varying position counts. This specific model represents a mid-range pin count option within the vertical header subset.

Replacement Considerations

Compatible substitutes include other 18-position, 3mm pitch, dual-row headers from the Minitek Pwr 3.0 series or equivalent Amphenol FCI power connector lines. Ensure any replacement maintains the same vertical orientation, through-hole termination, and LCP housing material for mechanical fit.
