10127721-205GLF

Overview

The Amphenol ICC (FCI) part number 10127721-205GLF is a Minitek Pwr 3.0 series power connector designed for board-to-board applications. It features a double row header configuration with 20 positions and a 3 mm pitch. The connector utilizes male pin contacts made of copper alloy, finished with gold plating to ensure reliable conductivity. Rated for 8.5 A current and 600 VAC voltage, it supports through-hole solder termination. The housing is constructed from black Liquid Crystal Polymer (LCP), offering UL94 V-0 flammability rating. Operating temperatures range from -40°C to +105°C, with an insulation resistance of 1 GOhms.

Feature Summary

• Double row straight header design for high-density power distribution
• Gold-plated copper alloy contacts for enhanced corrosion resistance
• LCP housing material providing high thermal stability and flame retardancy

Applications

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

Procurement Notes

Verify the specific suffix GLF indicates tin-free compliance when required by environmental regulations. Confirm that the 20-position count matches the target PCB footprint. Ensure the through-hole mounting style aligns with the assembly process capabilities. Cross-reference the 3 mm pitch against mating connector specifications to prevent mechanical interference.

Selection Notes

Select this component when a robust power interface with high current carrying capacity is required in a compact form factor. The 3 mm pitch allows for significant spacing between pins, reducing arcing risks compared to finer pitches. The gold finish is suitable for environments where contact reliability over multiple cycles or long-term exposure is critical. Consider the straight orientation for standard vertical stacking requirements.

Part Context

This part belongs to the Minitek Pwr 3.0 family, a specialized line of power connectors from Amphenol FCI. The series is engineered for demanding industrial and infrastructure applications requiring high reliability. Similar parts in the series vary by position count and termination style, sharing the same 3 mm pitch and electrical ratings. The product line emphasizes durability and consistent performance under thermal stress.

Replacement Considerations

Direct substitutes within the Minitek Pwr 3.0 series include other 20-position variants such as 10127721-201GLF or 10127721-205NRLF, depending on the required contact plating and packaging type. Verify that any alternative maintains the same 3 mm pitch and double-row configuration to ensure mechanical compatibility.
