10127721-186LF

Overview

The Amphenol ICC (FCI) 10127721-186LF is a Minitek Pwr 3.0 series power-to-board header connector designed for through-hole mounting. It features an 18-position, double-row configuration with a 3.00 mm pitch and vertical orientation. The contacts are male pins made of copper alloy with tin plating, rated for 600 VAC/DC and varying current based on wire gauge. The housing is constructed from black thermoplastic material with UL94 V-0 flammability rating. Key mechanical dimensions include a contact length of 3.20 mm, insulation height of 11.00 mm, and row spacing of 3.00 mm. It operates within a temperature range of -40°C to +105°C and includes board rail guides and locking pin slides for secure assembly.

Feature Summary

• Provides reliable power distribution in compact board-to-cable applications
• Features integrated board rails and locking mechanisms for secure installation
• Utilizes durable thermoplastic insulation with high flammability ratings

Applications

• Power supply modules requiring robust interconnects
• Industrial control systems needing vibration-resistant connections
• Telecommunications equipment power distribution boards

Procurement Notes

Verify the specific tin plating thickness and current derating curves against your application requirements before ordering. Confirm that the vertical through-hole footprint matches your PCB design constraints. Ensure compatibility with mating cable assemblies or harnesses intended for this connector series. Check for any recent product change notifications regarding material updates.

Selection Notes

Select this component when a vertical, double-row power header with 3.00 mm spacing is required. Consider the tin-plated contacts for general-purpose use rather than high-corrosion environments. Evaluate the 600 VAC rating and thermal limits to ensure they meet system safety standards. Compare against other Minitek Pwr variants if different pitch or row configurations are needed.

Part Context

This part belongs to the Minitek Pwr 3.0 family, which offers flexible solutions for power applications up to 8.5A. The series provides various position counts and mounting styles to support diverse electronic designs. Amphenol FCI designs these connectors to withstand harsh environmental conditions while maintaining signal integrity and mechanical stability.

Replacement Considerations

No direct public substitute part numbers are confirmed for this specific variant. Cross-reference with other Minitek Pwr 3.0 headers if alternative packaging or slight dimensional variations are acceptable. Verify electrical ratings and mechanical fit before considering any generic replacements.
