Overview
The Amphenol ICC (FCI) part number 10127819-24321LF is a Minitek Pwr 4.2 series power connector designed for board-to-board applications. It features a dual-row header configuration with 24 positions and a 4.2 mm pitch. The contacts are constructed from brass with a locking ramp fastening mechanism. This component supports surface mount or through-hole termination and operates within a temperature range of -40°C to +105°C.
Feature Summary
- Dual-row header design for high-density power distribution
- Locking ramp mechanism ensures secure mating engagement
- Brass contact material provides reliable electrical conductivity
Applications
- Server and storage equipment power distribution
- Telecommunications infrastructure boards
- Industrial control system power interfaces
Procurement Notes
Verify the specific termination style and plating requirements against the official datasheet before ordering, as suffixes may indicate variations in packaging or finish. Confirm availability through authorized distributors, as lead times can vary based on manufacturing schedules. Ensure compatibility with mating receptacles within the same Minitek Pwr 4.2 family.
Selection Notes
Select this component when a 24-position, 4.2mm pitch power interface is required. Consider the locking ramp feature for enhanced mechanical stability during vibration. Verify that the operating temperature range meets the environmental conditions of the target application. Compare current ratings against circuit demands to ensure safe operation.
Part Context
This connector belongs to the Minitek Pwr 4.2 series, a line of robust power connectors engineered for demanding environments. The series is widely utilized in datacom and telecom sectors where reliable power delivery and mechanical durability are critical. Amphenol FCI designs these components to support high-current applications with consistent performance.
Replacement Considerations
Compatible substitutes include other headers within the Minitek Pwr 4.2 series with matching pin counts and pitch. Verify that alternative parts maintain the same locking ramp mechanism and contact material specifications to ensure interchangeability without redesigning the PCB footprint.
