10137785-041212LF

Overview

The Amphenol ICC (FCI) part number 10137785-041212LF is a power-to-board header from the Minitek Power 4.2 series. It features a vertical through-hole mounting style with four positions and a 4.2 mm pitch. The connector utilizes copper contacts with a tin plating finish. Designed for high-current applications, it supports a voltage rating of 600 VAC and a current capacity of 12.5 A per contact. The housing is constructed from black liquid crystal polymer (LCP), ensuring thermal stability within an operating temperature range of -40°C to +105°C.

Feature Summary

• High current density capability supporting up to 12.5 A per contact
• Robust insulation resistance of 1 GOhms using LCP housing material
• Vertical through-hole solder termination for secure board attachment

Applications

• Power distribution modules in industrial equipment
• Server and storage system backplanes
• High-power LED driver connections

Procurement Notes

Verify the specific contact plating configuration against project requirements, as the suffix indicates tin plating which differs from gold options in the same series. Confirm that the 4.2 mm pitch aligns with the target PCB footprint design. Ensure the 600 VAC rating meets the electrical isolation standards of the intended application environment before finalizing procurement.

Selection Notes

Select this component when high current carrying capacity is required in a compact vertical form factor. The 4.2 mm pitch allows for wider contact spacing compared to signal connectors, reducing arcing risks. Consider the LCP material properties for high-temperature soldering processes. Compare against other Minitek Power variants if different pin counts or plating materials are needed for corrosion resistance.

Part Context

This connector belongs to the Minitek Power 4.2 family, designed for robust power interconnects. It complements matching receptacles and cable assemblies within the same product line. The series emphasizes reliability in demanding environments, offering various position counts and termination styles to support diverse power delivery architectures across electronics manufacturing sectors.

Replacement Considerations

Direct substitutes include other 4-position, 4.2 mm pitch headers from the Minitek Power 4.2 series with identical tin plating and vertical orientation. Verify mechanical dimensions and mating force specifications when evaluating alternative manufacturers' equivalents to ensure compatibility with existing assembly tooling.
