10120578-201LF

Overview

The Amphenol ICC (FCI) part number 10120578-201LF is a dual-sided card edge connector designed for board-to-board applications. It features 20 positions with a female contact type, utilizing a 0.031-inch (0.79mm) pitch. The connector supports a card thickness of 0.062 inches (1.57mm) and employs a press-fit termination method for through-hole mounting. Contact surfaces are finished with gold or GXT™ plating to ensure reliable signal transmission. Constructed from thermoplastic insulation and copper alloy contacts, this component operates within a temperature range of -55°C to 105°C.

Feature Summary

• Dual-sided female configuration for secure card edge engagement
• Gold or GXT™ contact finish for enhanced conductivity and corrosion resistance
• Press-fit termination ensures robust mechanical stability on the PCB
• Thermoplastic housing provides structural integrity and thermal resilience

Applications

• High-performance computing server backplanes
• Telecommunications infrastructure equipment
• Industrial control system modules
• Network switching hardware

Procurement Notes

Verify the specific contact finish variant (standard gold versus GXT™) against project requirements, as both options exist within this part family. Confirm that the manufacturing source is an authorized Amphenol distributor to guarantee authenticity. Ensure the procurement documentation includes the official datasheet for accurate dimensional verification before integration into production lines.

Selection Notes

Select this connector when a dual-sided interface with press-fit termination is required for high-density signal routing. The 0.031-inch pitch allows for compact board layouts while maintaining electrical reliability. Consider the operating temperature range and material compatibility with the target PCB stack-up to ensure long-term performance under thermal cycling conditions.
