10127721-185LF

Overview

The Amphenol ICC (FCI) part number 10127721-185LF is a Minitek Pwr 3.0 series power-to-board header connector. It features a dual-row, vertical through-hole mounting style with 18 positions and a 3 mm pitch. The connector utilizes copper alloy pins with gold plating for reliable electrical contact. Rated for 8.5 A current and 600 VAC voltage, it operates within a temperature range of -40°C to +105°C. The housing is constructed from black liquid crystal polymer (LCP), providing high insulation resistance and thermal stability for demanding power distribution applications.

Feature Summary

• Dual-row vertical design optimized for board-to-board power transmission
• Gold-plated copper contacts ensure low contact resistance and durability
• High-temperature LCP housing supports operation up to 105°C
• Through-hole solder termination provides secure mechanical fixation

Applications

• Server and storage system power distribution
• Telecommunications equipment power interfaces
• Industrial control board power connections
• High-density power supply modules

Procurement Notes

Verify the specific suffix against official Amphenol documentation to confirm plating thickness and material composition. Ensure the selected variant matches the required current rating and environmental specifications for the target application. Cross-reference the full part number with manufacturer datasheets to validate compatibility with mating sockets and PCB layout requirements before procurement.

Selection Notes

Select this component based on the 3 mm pitch requirement and 18-position count for the specific circuit design. Confirm that the 8.5 A current rating and 600 VAC voltage withstand meet the system's electrical demands. Evaluate the vertical orientation and through-hole termination method against available PCB space and assembly constraints. Verify that the operating temperature range aligns with the environmental conditions of the final product deployment.

Part Context

This connector belongs to the Minitek Pwr 3.0 family, designed for robust power delivery in compact electronic assemblies. The series emphasizes high current capacity and reliability in dense configurations. As an FCI product, it integrates into broader interconnect solutions used in critical infrastructure and computing hardware, supporting stable power transfer between boards in challenging operational environments.

Replacement Considerations

Consult official Amphenol cross-reference guides for verified substitute part numbers. Ensure any replacement maintains identical pin count, pitch, and electrical ratings. Verify mechanical compatibility with existing housings and mating connectors before implementation.
