Overview
The Amphenol ICC (FCI) part number 10127819-20111LF is a Minitek Pwr 4.2 series header connector designed for power-to-board applications. It features a right-angle through-hole mounting style with a 4.2 mm (0.165 inch) mating pitch and a 4.2 mm row spacing. The connector supports 20 positions in a dual-row configuration, utilizing square male pin contacts made of brass with tin plating. Rated for 600V, it employs a natural polyamide (PA66) insulation housing with UL94 V-0 flammability rating. The assembly includes a four-wall shielded cover and slide-lock fastening mechanism, operating within a temperature range of -40°C to 105°C.
Feature Summary
- High-voltage capability rated at 600V for robust power distribution
- Integrated four-wall shielded cover for enhanced environmental protection
- Slide-lock fastening system ensures secure mechanical retention
Applications
- Power supply modules requiring high-current connections
- Industrial control systems with harsh environmental demands
- Server and storage equipment internal power buses
Procurement Notes
Verify the specific contact plating thickness and material composition against the official datasheet before integration. Confirm that the right-angle orientation and 20-position count align with the target PCB layout constraints. Ensure compatibility with the mating socket series within the Minitek Pwr 4.2 family to guarantee proper engagement and electrical continuity.
Selection Notes
Select this component when a 600V rated, right-angle header with integrated shielding is required. The 4.2mm pitch accommodates higher current capacities compared to smaller pitches. Consider the through-hole mounting requirement and the need for a slide-lock mechanism for vibration resistance in the final application design.
Part Context
This connector belongs to the Minitek Pwr 4.2 series by Amphenol ICC (FCI), specialized for power delivery. The series offers various configurations including vertical and right-angle headers with different position counts. This specific model provides a 20-position solution with tin-plated contacts, balancing cost-effectiveness with reliable performance for general power applications.
Replacement Considerations
Compatible substitutes include other 20-position, 4.2mm pitch right-angle headers from the same Minitek Pwr 4.2 series, such as 10127819-2011GPTLF (gold plated) or 10127819-2011LCLF (gold with cover). Verify identical mechanical dimensions and locking mechanisms before substitution.
