10123908-A21LF

Overview

The Amphenol ICC (FCI) part number 10123908-A21LF is a female edgeboard connector designed for PCI Express Mini Card applications. It features a dual-row configuration with 52 positions and a contact spacing of 0.031 inches (0.80mm). The connector utilizes gold or Gold GXT™ surface finishes on copper alloy contacts to ensure reliable signal transmission. Constructed with thermoplastic insulation, it supports through-hole termination and includes board lock features for secure mounting. The housing is black, and the component is rated for operation within standard industrial temperature ranges.

Feature Summary

• Zero insertion force design compatible with PCI Express Mini Card modules
• Gold or Gold GXT™ contact plating for enhanced conductivity and corrosion resistance
• Integrated board lock mechanism to prevent accidental disconnection during operation
• Through-hole termination style ensuring stable mechanical attachment to the host PCB

Applications

• PCI Express Mini Card slot interconnects
• Wireless communication module interfaces
• Solid-state drive expansion slots in compact computing devices

Procurement Notes

Verify that the specific ordering suffix matches the required contact finish and packaging format. Confirm that the procurement channel provides traceable documentation for RoHS compliance and material declarations. Ensure the received components match the specified 52-position count and 0.80mm pitch dimensions before integration into the assembly process.

Selection Notes

Select this component when a low-profile, high-density interface is required for miniaturized form factors. The dual-row layout maximizes pin count within a constrained footprint. Evaluate the thermal performance requirements against the thermoplastic insulation limits. Consider the through-hole mounting method if superior mechanical strength is prioritized over surface mount space savings.

Part Context

This connector belongs to the HPCE® series from Amphenol ICC (FCI), which specializes in high-performance edgeboard solutions.
