Overview
The Amphenol ICC (FCI) 10127819-20221LF is a Minitek Power4.2 series power-to-board connector header. It features a double row, right-angle through-hole design with 20 positions and a 4.2 mm pitch. The contacts are made of brass with a tin finish. Rated for 9 A current, it operates within a temperature range of -40°C to +105°C and offers an insulation resistance of 1 GOhms.
Feature Summary
- Double row right-angle configuration for efficient board space utilization
- Tin-plated brass contacts ensure reliable electrical conductivity
- High current rating supports demanding power distribution requirements
Applications
- Server and storage equipment power distribution
- Telecommunications infrastructure boards
- Industrial control system power interfaces
Procurement Notes
Verify the specific contact plating thickness and material composition against the official datasheet before integration. Confirm that the right-angle mounting orientation aligns with the mechanical constraints of the target PCB layout. Ensure compatibility with mating receptacles from the same Minitek Power4.2 family.
Selection Notes
Select this component when a high-current, low-profile power interface is required in a constrained vertical space. The right-angle design facilitates direct board stacking or side-access connections. Verify that the 4.2 mm pitch matches the existing footprint and that the tin finish meets the environmental corrosion resistance standards for the intended application.
Part Context
This part belongs to the Minitek Power4.2 series by Amphenol FCI, designed for robust power delivery in compact electronic systems. The series provides various configurations including vertical and right-angle headers with different pin counts and plating options to suit diverse industrial and data communication applications.
Replacement Considerations
Compatible substitutes include other Minitek Power4.2 series headers with identical 20-position, right-angle, through-hole specifications. Ensure replacement parts maintain the 4.2 mm pitch and 9 A current rating. Verify that alternative suppliers offer equivalent tin-plated brass contacts and operating temperature ranges.
