10127819-24221LF

Overview

The Amphenol ICC (FCI) part number 10127819-24221LF is a right-angle board-to-board and mezzanine connector header from the Minitek Pwr 4.2 series. It features 24 positions with a 4.20 mm pitch, arranged in two rows. The connector utilizes male pin contacts made of brass with tin plating. Designed for through-hole mounting, it has an insulation height of 9.80 mm and a contact length of 3.50 mm. The housing is black polyamide (PA66), rated for operation between -40°C and +105°C, with a UL94 V-0 flammability rating.

Feature Summary

• Right-angle through-hole header design for compact vertical space constraints
• High-current capability within the Minitek Pwr 4.2 power connector family
• Robust mechanical locking via integrated ramp fastening system
• Four-wall shielded housing structure for improved environmental protection

Applications

• Server and storage backplane interconnects
• Industrial control system power distribution
• Telecommunications equipment internal power routing
• High-density electronic assembly power supply connections

Procurement Notes

Verify the specific suffix '24221' against official Amphenol documentation to confirm exact pin count, plating thickness, and packaging configuration. Ensure compatibility with mating receptacles in the same Minitek Pwr 4.2 series. Confirm that the right-angle orientation and through-hole termination method match the target PCB layout requirements before finalizing procurement orders.

Selection Notes

Select this component when a high-current, right-angle power connection is required in a dense assembly. The 4.2 mm pitch allows for significant current carrying capacity compared to smaller signal connectors. Ensure the mating connector supports the 24-position configuration and that the PCB silkscreen and drill patterns align with the through-hole pin dimensions specified in the datasheet.

Part Context

This connector belongs to the Minitek Pwr 4.2 series, designed for demanding power applications in server and communication infrastructure. The series offers various configurations including vertical and right-angle headers with different position counts. The 10127819 base number indicates a right-angle header variant within this robust power interconnect family.

Replacement Considerations

Direct substitutes must share the 4.2 mm pitch, 24-position count, right-angle orientation, and through-hole termination. Verify that any alternative maintains the same current rating and UL94 V-0 insulation rating. Cross-reference with other Minitek Pwr 4.2 variants only if they match all physical and electrical parameters exactly.
