10137785-032131LF

Overview

The Amphenol ICC (FCI) part number 10137785-032131LF is a Minitek Pwr 4.2 series power connector designed for board-to-board applications. It features a vertical header configuration with three positions and a 4.2 mm pitch. The contacts are copper-based with gold plating, rated for 12.5 A current and 600 V voltage. The housing is black thermoplastic with UL94 V-0 flammability rating. Operating temperature range is -40°C to +105°C. Insulation resistance is 1 GOhm.

Feature Summary

• Vertical board-to-board power interconnect solution
• High current capacity with gold-plated contacts
• Secure mechanical locking design

Applications

• Industrial control systems
• Power distribution units
• Server backplanes

Procurement Notes

Verify the specific suffix 'LF' indicates lead-free compliance against manufacturer specifications. Confirm that the 3-position variant matches the required circuit density. Check for RoHS status updates as product lifecycle stages may change. Ensure the vertical orientation fits the assembly height constraints. Validate the 4.2mm pitch compatibility with mating connectors.

Selection Notes

Select this component when high current carrying capability is required in a compact vertical form factor. The 4.2mm pitch allows for significant spacing between power traces. Consider the 12.5A rating per contact for load requirements. Verify insulation material properties for thermal stability. Ensure the locking mechanism meets insertion force requirements.
