10127820-0421PLF

Overview

The Amphenol ICC (FCI) part number 10127820-0421PLF is a Minitek Power4.2 series board-to-board and mezzanine connector header. It features a double-row vertical through-hole design with four positions. The contact pitch is 4.2 mm, and the insulation height measures 0.504 inches (12.80 mm). The housing is constructed from black polyamide (PA66/Nylon 6/6) with a UL94 V-0 flammability rating. Termination is achieved via solder pins suitable for surface mount or through-hole assembly processes.

Feature Summary

• Double-row vertical header configuration for board-to-board interconnection
• Through-hole termination style utilizing solder pin technology
• Polyamide insulation housing with UL94 V-0 flame retardant rating
• Black colored housing material for visual identification

Applications

• High-density board-to-board stacking assemblies
• Mezzanine card interconnect systems
• Industrial control unit signal routing
• Telecommunications equipment backplane connections

Procurement Notes

Verify the specific ordering suffix requirements directly with Amphenol FCI to ensure compatibility with intended manufacturing processes. Confirm that the 4.2 mm pitch aligns with the target PCB land pattern dimensions. Request current lifecycle status documentation to confirm long-term availability for production runs. Validate that the through-hole termination method matches the assembly equipment capabilities. Ensure the specified insulation height accommodates the required mechanical stack-up constraints within the final enclosure design.

Selection Notes

Select this component when a robust 4.2 mm pitch connection is required between stacked circuit boards. The double-row layout maximizes contact density within a compact footprint. Verify that the application environment remains within the standard operating temperature range. Ensure the mechanical clearance allows for the 12.80 mm insulation height. Consider the through-hole mounting requirement against available PCB drilling and soldering infrastructure.

Part Context

This connector belongs to the Minitek Power4.2 product family, designed for reliable power and signal transmission in demanding environments. The series emphasizes durability and high contact force reliability. Amphenol FCI utilizes this platform for applications requiring secure mechanical locking and consistent electrical performance across multiple mating cycles.

Replacement Considerations

No public confirmed substitute part numbers are documented for this specific component. Direct replacement requires identical pitch, row count, and termination specifications.
