Overview
The Amphenol ICC (FCI) part number 10127820-0424LLF is a Minitek Power4.2 series power connector header designed for board-to-board applications. It features a dual-row vertical through-hole configuration with four positions and a 4.2 mm pitch. The contacts are constructed from brass with a 30-microinch gold plating to ensure reliable conductivity. Rated for 9 A current, the component operates within a temperature range of -40°C to +105°C and exhibits an insulation resistance of 1 GOhm.
Feature Summary
- Dual-row vertical through-hole header design
- Gold-plated brass contacts for corrosion resistance
- High current rating capability
Applications
- Power distribution in industrial equipment
- Server and storage system power connections
- Communication device power interfaces
Procurement Notes
Verify the specific ordering suffix 'LLF' against official Amphenol documentation to confirm lead-free compliance and packaging specifications. Confirm that the 4-position variant matches the required circuit density. Ensure compatibility with mating sockets within the same Minitek Power4.2 family before finalizing procurement orders.
Selection Notes
Select this component when a low-profile, high-current vertical interconnect is required for power delivery. The 4.2 mm pitch accommodates higher current loads compared to smaller pitches. Verify that the PCB layout supports the dual-row through-hole termination style and that the operating environment remains within the specified thermal limits.
Part Context
This connector belongs to the Minitek Power4.2 product line manufactured by Amphenol ICC (FCI). The series is engineered for robust power transmission in demanding environments. It provides a standardized solution for connecting power sources to printed circuit boards in various electronic systems requiring reliable electrical continuity.
Replacement Considerations
Compatible substitutes include other 4-position headers from the Minitek Power4.2 series, such as 10127820-0424LCLF or 10127820-0424GPLF, provided they match the vertical orientation and contact plating requirements.
