Overview
The Amphenol ICC (FCI) part number 10137785-033121LF is a Minitek Pwr 4.2 series power connector designed for board-to-board applications. It features a 3-position configuration with a 4.2 mm pitch and a vertical mounting orientation. The connector utilizes copper alloy contacts with gold plating to support a current rating of 12.5 A per contact. Operating within a temperature range of -40°C to +105°C, it employs Polyamide insulation and includes board lock features for secure installation.
Feature Summary
- Designed for high-current power-dense applications
- Vertical surface mount or through-hole compatible header
- Includes board lock mechanism for stability
Applications
- Power distribution in compact electronic systems
- High-density server and storage backplanes
- Industrial control boards requiring robust power connections
Procurement Notes
Verify the specific suffix and revision level against the manufacturer's latest datasheet before procurement. Confirm that the gold contact finish and Polyamide insulation meet the thermal and electrical requirements of the target application. Ensure compatibility with mating receptacles from the same Minitek Pwr 4.2 family to maintain proper alignment and current carrying capacity.
Selection Notes
Select this component when a vertical power interface with a 4.2 mm pitch is required. The 12.5 A rating suits moderate power loads. Consider the operating temperature range and board lock feature for mechanical reliability. Verify that the manufacturing status aligns with long-term production needs, as availability may vary.
Part Context
This part belongs to the Minitek Pwr 4.2 Higher Current Connectors (HCC) line by Amphenol ICC (FCI). This series is engineered for demanding environments where space efficiency and high current handling are critical. The design supports reliable power transmission in dense layouts common in modern electronics.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Evaluate other Minitek Pwr 4.2 variants with matching position counts and pitch specifications if direct substitution is necessary.
