Overview
The Amphenol ICC (FCI) part number 10127819-20311PLF is a Minitek Power4.2 series power-to-board connector header. It features 20 positions with a 4.2 mm pitch and is designed for right-angle through-hole mounting. The contacts are brass with gold plating, rated for 9 A current and 600 VAC voltage. Operating temperature ranges from -40°C to +105°C. Insulation resistance is 1 GOhms. Housing material is nylon with natural color.
Feature Summary
- Supports high-current power distribution via 9 A rating per contact
- Right-angle design facilitates compact board layout integration
- Gold-plated brass contacts ensure reliable conductivity and corrosion resistance
Applications
- Power delivery in industrial control systems
- Server and storage equipment internal power connections
- Communication infrastructure power boards
Procurement Notes
Verify the exact position count and housing color against official datasheets, as suffixes may indicate variations. Confirm RoHS compliance status if required by project specifications. Check lead times due to potential supply chain fluctuations for standard FCI components. Ensure compatibility with mating receptacles of the same Minitek Power4.2 series.
Selection Notes
Select this component when a 20-position, right-angle power header is needed. The 4.2 mm pitch accommodates higher currents compared to smaller pitches. Verify that the PCB layout supports through-hole assembly for right-angle headers. Consider thermal management requirements given the 9 A rating and 105°C operating limit.
Part Context
This part belongs to the Minitek Power4.2 series, a line of robust power connectors from Amphenol ICC (FCI). The series is known for high current capacity and durability in demanding environments. It complements other Minitek variants like the 1.27mm signal connectors, offering a complete solution for mixed-signal and power applications.
Replacement Considerations
Direct substitutes include other 20-position Minitek Power4.2 headers from Amphenol ICC (FCI), such as 10127819-20311GLF or similar suffixes. Cross-brand replacements require verifying pitch, current rating, and mechanical dimensions. Ensure mating connector compatibility before substitution.
