10127721-125SLF

Overview

The Amphenol ICC (FCI) part number 10127721-125SLF is a Minitek Pwr 3.0 series power connector header designed for board-to-board applications. It features a dual-row configuration with 12 positions and a 3 mm pitch. The component utilizes male pin contacts made of copper alloy with tin plating, rated for 8.5 A current and 600 VAC voltage. Designed for through-hole mounting at a straight angle, it operates within a temperature range of -40°C to +105°C. The housing is constructed from natural Liquid Crystal Polymer (LCP) with an insulation resistance of 1 GOhms.

Feature Summary

• Dual-row vertical header design optimized for high-current power distribution
• Robust LCP housing material providing thermal stability and high insulation resistance
• Through-hole solder pin termination ensuring secure mechanical attachment

Applications

• Server and storage equipment power distribution
• Telecommunications infrastructure boards
• Industrial control system power headers

Procurement Notes

Verify the specific contact plating variant during procurement, as the suffix 'SLF' typically indicates tin plating in this series, whereas other variants may use gold. Confirm that the 12-position count matches the design requirement, as the Minitek Pwr 3.0 series offers multiple position options. Ensure the through-hole footprint aligns with the PCB layout specifications before finalizing the order.

Selection Notes

Select this component when a 3 mm pitch power header is required for high-current applications up to 8.5 A per contact. The straight, through-hole style is suitable for standard PCB assembly processes. Consider the operating temperature range of -40°C to +105°C for environmental compatibility. Verify that the natural LCP housing meets the visual or regulatory requirements of the end product.

Part Context

This connector belongs to the Minitek Pwr 3.0 family, a specialized line of power connectors by Amphenol FCI. The series is engineered for demanding environments, offering reliable connections in server, storage, and communication systems. The 10127721 prefix identifies the specific header form factor within the broader Minitek portfolio.

Replacement Considerations

Direct substitutes include other 12-position, 3 mm pitch dual-row headers from the same Minitek Pwr 3.0 series, such as 10127721-104PLF or 10127721-121SLF, provided the contact plating and housing color meet the application needs. Cross-brand replacements require careful verification of pitch, row count, and current ratings.
