10127819-20321LF

Overview

The Amphenol ICC (FCI) part number 10127819-20321LF is a Minitek Pwr 4.2 series header connector designed for power applications. It features a 20-position configuration with a 4.20mm pitch and operates as a right-angle through-hole device. The contacts are constructed from brass with gold plating, rated at 15.0µin thickness. Rated for 600V and up to 9A depending on wire gauge, it utilizes a four-wall shielded housing made of polyamide (PA66). Key mechanical specifications include a contact length of 0.138 inches and an insulation height of 0.386 inches.

Feature Summary

• Supports high-voltage power transmission with a 600V rating
• Provides robust mechanical stability via right-angle through-hole mounting
• Ensures reliable electrical contact through gold-plated brass terminals
• Includes four-wall shielding for enhanced signal integrity

Applications

• Industrial control systems requiring high-power distribution
• Server and storage infrastructure power modules
• Telecommunications equipment power interfaces
• Automotive electronics power connections

Procurement Notes

Verify the specific ordering suffix to confirm contact finish and packaging type. Ensure compatibility with mating receptacles regarding current ratings and voltage limits. Confirm that the PCB footprint matches the specified dimensions for right-angle mounting. Check RoHS compliance status if required by project regulations. Validate thermal performance under maximum load conditions before final integration.

Selection Notes

Select this component when a 4.20mm pitch is required for high-current applications. Consider the right-angle form factor for space-constrained vertical board layouts. Evaluate the 600V rating against system voltage requirements. Compare alternative pin counts within the same Minitek Pwr 4.2 family if different I/O density is needed. Assess the need for shielding in noisy electromagnetic environments.

Part Context

This connector belongs to the Minitek Pwr 4.2 series, which is engineered for demanding power delivery scenarios. The series offers various pin counts and termination styles to accommodate diverse design constraints. It represents a standardized solution for reliable power interconnection in compact electronic assemblies.

Replacement Considerations

Direct substitutes may include other 20-position headers with identical 4.20mm pitch and right-angle mounting. Verify that any replacement maintains the 600V rating and compatible contact materials. Cross-reference mechanical drawings to ensure PCB hole alignment and housing depth match.
