Overview
The Amphenol ICC (FCI) part number 10127819-18121LF is a Minitek Power4.2 series header connector designed for power-to-board applications. It features an 18-position configuration with a 4.2 mm pitch and dual-row arrangement. The component utilizes brass contacts with gold flash plating to ensure reliable conductivity and corrosion resistance. Rated for 9 A current, it supports vertical installation via solder termination on printed circuit boards. The operating temperature range spans from -40°C to +105°C, providing stability in demanding environments.
Feature Summary
- Dual-row vertical header design for compact power distribution
- Gold flash contact plating ensures reliable electrical performance
- High current rating of 9 A per position for efficient power delivery
- Robust construction withstands temperatures up to 105°C
Applications
- Server and storage equipment power distribution
- Telecommunications infrastructure board connections
- Industrial control system power interfaces
- Data processing unit internal power routing
Procurement Notes
Verify the specific ordering suffix against the manufacturer's latest datasheet to confirm contact plating specifications and mechanical tolerances. Ensure compatibility with mating card edge thicknesses and verify that the selected variant meets the required current carrying capacity for the target application environment before finalizing procurement orders.
Selection Notes
Select this component when high-current power delivery is required in a space-constrained vertical layout. The 4.2 mm pitch accommodates substantial conductors while maintaining a low profile. Consider the gold flash finish for superior oxidation resistance compared to tin variants in corrosive or high-humidity operational settings.
Part Context
This connector belongs to the Minitek Power4.2 family, engineered for robust power transmission in dense electronic assemblies. The series offers various pin counts and termination options to support diverse board-to-card interconnect needs within server, storage, and communication hardware architectures.
Replacement Considerations
Cross-reference with other Minitek Power4.2 headers sharing identical 18-position layouts and vertical orientation. Verify that substitute parts maintain matching 4.2 mm pitch dimensions and compatible housing materials to ensure proper mechanical fit and electrical continuity.
