10127819-20312PLF

Overview

The Amphenol ICC (FCI) part number 10127819-20312PLF is a Minitek Pwr 4.2 series power-to-board header connector. It features a dual-row configuration with 20 positions and a 4.2 mm pitch. The connector utilizes male pin contacts with gold plating for reliable electrical interfacing. Designed for through-hole mounting, it offers a right-angle orientation to facilitate board edge connections. The housing is constructed from natural-colored material rated UL94 V-0 for flammability. It supports an operating temperature range of -40°C to +105°C and carries a current rating of 9 A per contact.

Feature Summary

• Dual-row blade-style power connector designed for high-current applications
• Right-angle through-hole mounting for efficient board layout integration
• Gold-plated brass contacts ensure stable signal and power transmission
• Integrated board lock mechanism provides secure mechanical retention

Applications

• Server and storage system power distribution
• Telecommunications equipment backplanes
• Industrial control board interconnects
• High-density power supply modules

Procurement Notes

Verify the specific suffix '2PLF' against the manufacturer's latest datasheet to confirm plating thickness and material composition. Ensure compatibility with mating receptacles in the same Minitek Pwr 4.2 family. Confirm RoHS compliance status as some variants may differ. Check for obsolescence notices or PCNs affecting lead time or specifications before finalizing procurement orders.

Selection Notes

Select this component when a 20-position, 4.2 mm pitch right-angle header is required for power delivery. Ensure the PCB design accommodates through-hole soldering and right-angle clearance. Verify that the mating connector matches the dual-row blade style. Consider thermal management requirements given the 9 A current rating and 105°C maximum operating temperature limit.

Part Context

This connector belongs to the Minitek Pwr 4.2 family, a specialized line of power connectors by Amphenol ICC (formerly FCI). The series is engineered for robust power distribution in demanding environments. It integrates signal and power capabilities within a compact form factor, supporting high-speed data and high-current power simultaneously in server and communication infrastructure applications.

Replacement Considerations

Direct substitutes include other 20-position, 4.2 mm pitch right-angle headers from the Minitek Pwr 4.2 series with matching gold plating. Verify mechanical dimensions and locking features match exactly. Cross-reference with Amphenol ICC official cross-reference lists for validated replacements.
