Overview
The Amphenol ICC (FCI) part number 10127721-121RLF is a Minitek Power3.0 series double-row vertical through-hole header connector. It features 12 positions with a 3.00 mm pitch and square pin contacts. The connector utilizes tin-plated copper alloy terminals housed in black thermoplastic insulation rated UL94 V-0. Designed for power applications, it supports a maximum operating temperature of +105°C and a minimum of -40°C.
Feature Summary
- Double-row vertical configuration for high-density power distribution
- Through-hole solder termination for secure board mounting
- Tin-plated contacts to ensure reliable electrical conductivity
- UL94 V-0 flammability rating for thermal safety
Applications
- Power distribution modules in server infrastructure
- High-current connections in telecommunications equipment
- Industrial control system power interfaces
- Data center power supply unit interconnects
Procurement Notes
Verify the specific suffix 'RLF' against official Amphenol documentation to confirm tin plating versus gold options. Ensure the vertical orientation matches the design requirements. Confirm availability status as this component may be subject to special order constraints or limited regional distribution channels.
Selection Notes
Select this component when a 12-position, 3.00 mm pitch vertical header is required for power applications. The tin finish offers cost-effective conductivity suitable for environments where corrosion resistance is managed by other means. Verify that the 8.5 A current rating aligns with the circuit load requirements.
Part Context
This connector belongs to the Minitek Power3.0 family, designed for robust power-to-board connections. The series provides various row counts and orientations, including right-angle and vertical configurations, to accommodate diverse PCB layout needs in demanding electronic systems.
Replacement Considerations
Cross-reference with 10127721-163GLF for similar Minitek Power3.0 specifications, noting differences in position count and plating. Verify mechanical compatibility before substitution.
