10127905-A12A30DLF

Overview

The Amphenol ICC (FCI) part number 10127905-A12A30DLF is a dual-sided card edge connector designed for board-to-board applications. It features 40 positions with a female contact type, utilizing gold or GXT™ surface finish on copper alloy contacts. The connector supports a card thickness of 0.062 inches (1.57mm) and operates within a temperature range of -55°C to 105°C. It employs a through-hole termination method and includes a board lock feature for secure installation. The housing is constructed from thermoplastic material in black color, ensuring UL94 V-0 flammability rating.

Feature Summary

• Dual-sided configuration for comprehensive signal and power routing
• Integrated board lock mechanism for enhanced mechanical stability
• Gold or GXT™ contact finish for reliable conductivity and corrosion resistance

Applications

• High-density electronic assemblies requiring robust interconnects
• Industrial control systems operating in varied thermal environments
• Telecommunications infrastructure equipment

Procurement Notes

Verify the specific contact finish requirement, as options include standard gold or GXT™ plating which may affect performance characteristics. Confirm that the target PCB design accommodates the through-hole termination style and the physical dimensions required for the board lock feature. Ensure compatibility with the specified 0.062-inch card thickness to guarantee proper mating engagement and electrical continuity during operation.

Selection Notes

Select this component when a dual-sided card edge interface is necessary for high-reliability connections. The choice is driven by the need for a board lock feature to prevent accidental disengagement in vibration-prone environments. Consider the operating temperature range of -55°C to 105°C for suitability in harsh industrial conditions. The through-hole mounting provides superior mechanical strength compared to surface mount alternatives.

Part Context

This connector belongs to the broader category of card edge connectors manufactured by Amphenol ICC (FCI). It is specifically engineered for applications demanding durable, high-pin-count interconnections. The dual-sided design allows for increased I/O density within a compact footprint. The use of thermoplastic insulation ensures electrical isolation and structural integrity under thermal stress.

Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Verify pin count, spacing, and mounting style compatibility before considering any alternative components from different manufacturers.
