10137785-043142LF

Overview

The Amphenol ICC (FCI) part number 10137785-043142LF is a Minitek Pwr 4.2 series power-to-board connector header. It features a 4-position configuration with a 4.2 mm pitch and is designed for vertical through-hole mounting. The component utilizes copper contacts with tin plating, housed in a black liquid crystal polymer (LCP) body. It supports a current rating of 12.5 A per contact and operates within a temperature range of -40°C to +105°C.

Feature Summary

• Designed for high-current applications with ratings up to 13.5A per contact
• Utilizes liquid crystal polymer insulation for thermal stability
• Vertical through-hole termination for board integration

Applications

• Power-dense electronic systems
• Server and storage equipment power distribution
• Industrial control boards requiring high current capacity

Procurement Notes

Verify the specific ordering suffix to confirm contact plating type, as tin and gold variants exist within this series. Confirm that the 12.5A rating aligns with system requirements, noting that some datasheets cite higher peak capabilities. Ensure the vertical orientation matches the PCB layout constraints before finalizing procurement.

Selection Notes

Select this component when a robust power connection with a 4.2 mm spacing is required. The LCP material offers superior heat resistance compared to standard thermoplastics. Consider the tin plating for cost-effective solutions where corrosion resistance is managed by the operating environment.

Part Context

This connector belongs to the Minitek Pwr 4.2 Higher Current Connectors (HCC) family produced by Amphenol ICC (FCI). The series is engineered to provide reliable power delivery in compact spaces, serving as a critical interface between power sources and circuit boards in demanding environments.

Replacement Considerations

No direct public substitute part numbers are confirmed for this specific model. Evaluate other Minitek Pwr 4.2 headers if pin count or plating variations are acceptable.
