Overview
The Amphenol ICC (FCI) part number 10127820-1824LLF is a Minitek Power4.2 series power-to-board connector header. It features an 18-position, dual-row vertical configuration with a 4.2 mm pitch. The contacts are male pins made of brass with 30 microinch gold plating. Rated for 9 A current and operating between -40°C and +105°C, it offers 1 GOhm insulation resistance.
Feature Summary
- Dual-row vertical header design for board-to-board power distribution
- Gold-plated brass contacts ensure reliable conductivity and corrosion resistance
- High current rating supports demanding power delivery applications
Applications
- Server and storage equipment power distribution
- Industrial automation power modules
- Telecommunications infrastructure boards
Procurement Notes
Verify the specific suffix 'LLF' against official datasheets to confirm gold plating thickness and reel packaging requirements. Ensure mating connectors match the 4.2mm pitch and 18-position dual-row specification. Confirm RoHS compliance status and lead-free soldering compatibility before finalizing procurement orders.
Selection Notes
Select this component when high-current power delivery is required in a compact vertical form factor. The 4.2mm pitch allows for robust contact spacing suitable for power lines. Verify that the PCB layout accommodates the dual-row vertical header height and that mating sockets support the specified 9A current rating per contact.
Part Context
This connector belongs to the Minitek Power4.2 family, designed for high-power density applications. The series provides reliable interconnects for industrial and computing environments where durability and thermal performance are critical. It complements other Minitek solutions by offering standardized pin counts and pitches for scalable system designs.
Replacement Considerations
Check for 10127820-1824LCLF as a potential alternative with similar specifications but verify if the gold plating thickness or packaging format differs. Ensure any substitute maintains the 4.2mm pitch and 18-position dual-row configuration for mechanical compatibility.
