10125756-640110LF

Overview

The Amphenol ICC (FCI) part number 10125756-640110LF is a high-performance mezzanine connector belonging to the HPCE series. It is designed as a female card edge connector specifically for PCI Express applications. The component features 64 positions with a pitch of 0.039 inches (approximately 1.0 mm). It utilizes a straddle mount configuration, allowing it to bridge two adjacent slots on a motherboard. The connector supports PCIe Gen3 signal integrity requirements and is constructed with durable materials suitable for high-density electronic interconnects.

Feature Summary

• Straddle mount design enables connection across dual motherboard slots
• Optimized for PCI Express Gen3 signal integrity performance
• High-density 64-position female contact array

Applications

• PCI Express expansion slot interconnects
• High-speed data transmission backplanes
• Server and storage system motherboards

Procurement Notes

Verify the specific suffix and revision level against the manufacturer's latest datasheet to ensure compatibility with current PCB stack-up requirements. Confirm that the straddle mount footprint matches the target board layout precisely. Check for any recent product change notifications or end-of-life status updates from Amphenol ICC before finalizing procurement plans.

Selection Notes

Select this component when a dual-slot bridging solution is required for PCI Express interfaces. Ensure the host board design accommodates the specific straddle mount geometry and height restrictions. Validate electrical parameters against system bandwidth needs, particularly for Gen3 signaling speeds. Consider mechanical retention methods compatible with the card edge interface.

Part Context

This connector is part of the HPCE (High Performance Card Edge) family, which focuses on high-speed digital interconnects. The HPCE series is engineered to meet the demanding signal integrity and thermal requirements of modern computing platforms. This specific model represents a specialized variant within the broader portfolio of Amphenol ICC's mezzanine and card edge solutions.

Replacement Considerations

No direct public substitute part numbers are confirmed in available documentation. Evaluate pin-compatible alternatives only if this specific straddle mount configuration is unavailable. Verify all mechanical and electrical specifications match exactly before considering any cross-reference.
