10123920-A70LF

Overview

The Amphenol ICC (FCI) part number 10123920-A70LF is a PCI Express Mini Card female connector. It features 52 positions arranged in two rows with a 0.80mm pitch. The contact surface finish is gold, GXT™ type, with a thickness of 10.0µin (0.25µm). Designed for surface mount installation at a right angle, it utilizes solder termination and copper alloy contacts. The housing is black thermoplastic, rated for operation between -55°C and 85°C.

Feature Summary

• Supports PCI Express Mini Card interface standards
• Features board rail guidance for precise alignment
• Utilizes high-reliability gold plating for signal integrity

Applications

• PCI Express Mini Card edge card connections
• Wireless module integration in compact electronics
• Solid-state drive form factor adapters

Procurement Notes

Verify the specific ordering suffix A70LF to confirm the 10.0µin gold plating specification. Ensure compatibility with the 0.031 inch card thickness requirement. Confirm that the surface mount right-angle footprint matches the target PCB layout. Check RoHS compliance status against current manufacturing records.

Selection Notes

Select this component when a right-angle surface mount solution is required for PCI Express Mini Cards. The 0.80mm pitch accommodates standard mini-card dimensions. Consider the thermal rating range for environmental exposure. Evaluate the board rail feature for insertion stability needs.

Part Context

This connector belongs to the HPCE® series by Amphenol ICC (FCI), formerly FCI. The series specializes in high-performance card edge connectors for computing and communication markets. The manufacturer acquired FCI to expand its portfolio of signal integrity solutions.

Replacement Considerations

Check for 10123920-SB0LF if thicker gold plating is needed. Verify 10123920-A20LF for alternative plating specifications. Ensure substitute parts maintain the same 52-position count and 0.80mm pitch.
