10127819-04221LF

Overview

The Amphenol ICC (FCI) part number 10127819-04221LF is a Power to the Board header connector belonging to the Minitek Pwr 4.2 series. It features a 4-position configuration with a 4.2 mm pitch and two rows of contacts. The connector utilizes brass terminals with tin plating for reliable electrical performance. Designed for through-hole mounting, it offers a right-angle orientation to facilitate efficient board layout. The housing is constructed from natural-colored nylon, providing structural integrity and insulation. This component supports a maximum operating temperature range from -40°C to +105°C and is rated for 600VAC/DC applications.

Feature Summary

• Right-angle through-hole mounting style for optimized PCB space utilization
• Two-row header design accommodating four positions with 4.2 mm spacing
• Tin-plated brass contacts ensuring stable conductivity and corrosion resistance
• Nylon housing material offering UL94 V-0 flammability rating

Applications

• Power distribution in server and storage equipment
• Industrial control system interconnections
• Communication infrastructure power boards
• General-purpose high-current board-to-board connections

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm terminal plating and packaging details. Ensure compatibility with mating receptacles within the Minitek Pwr 4.2 family. Confirm that the right-angle form factor aligns with the mechanical constraints of the target assembly. Check for any recent product change notices regarding material specifications or manufacturing locations before finalizing procurement orders.

Selection Notes

Select this connector when a low-profile, high-current solution is required for power delivery on densely populated boards. The 4.2 mm pitch allows for higher current carrying capacity compared to smaller pitch systems. Consider the right-angle configuration if vertical clearance is limited but horizontal space is available. Ensure the application environment stays within the specified temperature range and voltage ratings for long-term reliability.

Part Context

This component is part of the Minitek Pwr 4.2 series by Amphenol ICC (FCI), designed for robust power connectivity. The series is widely used in datacom and telecom applications requiring reliable power transmission. The 10127819 prefix typically denotes headers in this lineup, while the suffix defines position count, row configuration, and mounting style variations.

Replacement Considerations

Direct substitutes may include other 4-position, 4.2 mm pitch right-angle headers from the same Minitek Pwr 4.2 family, such as variants with different plating options like gold. Verify mechanical dimensions and locking mechanisms match exactly. Cross-reference with Amphenol's official replacement guide for equivalent parts with updated suffixes.
