Overview
The Amphenol ICC (FCI) part number 10127819-18221LF is a Minitek Pwr 4.2 series header connector designed for board-to-cable or wire applications. It features an 18-position, dual-row configuration with a 4.20mm pitch and right-angle through-hole mounting. The contacts are made of brass with tin plating, housed in black polyamide (PA66) insulation rated UL94 V-0. Rated for 600V, it operates within a temperature range of -40°C to 105°C.
Feature Summary
- Minitek Pwr 4.2 series design for high-current power distribution
- Right-angle through-hole termination for PCB integration
- Four-wall shrouded housing for contact alignment and protection
Applications
- Industrial control systems requiring robust power connections
- Power supply units and distribution boards
- Consumer electronics with high-voltage internal wiring
Procurement Notes
Verify the specific suffix 'LF' confirms lead-free compliance and tin plating as documented. Confirm the 18-position count matches the target circuit requirements. Ensure the right-angle orientation aligns with the mechanical layout constraints of the assembly. Cross-reference the manufacturer's latest datasheet for any recent PCN updates regarding material changes.
Selection Notes
Select this component when a 4.20mm pitch is required for higher current capacity compared to standard 2.54mm headers. The right-angle form factor is suitable for space-constrained vertical PCB layouts. Verify that the 600V rating exceeds the system's maximum operating voltage. Consider the black color coding if visual differentiation from other connectors is necessary.
Part Context
This connector belongs to the Minitek Pwr 4.2 family, engineered for demanding power applications. It complements other variants in the series that offer different pin counts and plating options. The design emphasizes durability and secure mating in industrial environments, serving as a reliable interface between rigid PCBs and flexible wiring harnesses.
Replacement Considerations
Direct substitutes include other 18-position, 4.20mm pitch right-angle headers from compatible manufacturers. Ensure equivalent electrical ratings and mechanical dimensions before substitution. Variants like 10127819-16211LF differ in position count and require layout adjustments.
