10140903-1220BLF

Edgeboard Connectors Overview

The Amphenol ICC (FCI) 10140903-1220BLF is a dual-edge board connector designed for high-density interconnect applications. It features 32 positions, configured as 20 signal and 12 power contacts. The connector utilizes a female gender with gold and GXT™ contact plating to ensure reliable conductivity. It supports a card thickness of 0.062 inches (1.57mm) and employs a straddle mount installation style. The housing is black thermoplastic, suitable for robust mechanical retention in edgeboard configurations.

Edgeboard Connectors Feature Summary

• Dual-edge configuration supporting both signal and power transmission simultaneously
• Gold and GXT™ contact plating for enhanced corrosion resistance and low contact resistance
• Straddle mount design providing secure mechanical stability on the PCB
• Black thermoplastic housing optimized for high-density edgeboard environments

Edgeboard Connectors Applications

• High-performance computing server backplanes
• Telecommunications infrastructure equipment
• Industrial control systems requiring mixed signal/power connections
• Network switching hardware

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix to confirm contact plating type and housing color, as variations exist within the 10140903 series. Ensure compatibility with the target card thickness of 0.062 inches. Confirm that the straddle mount footprint aligns with the PCB layout requirements. Check for any recent Product Change Notifications regarding material substitutions or manufacturing location changes before finalizing procurement.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge solution is required to maximize I/O density on a single connector interface. The 20+12 position split allows for dedicated power routing separate from signal lines, reducing noise interference. Verify that the mating card meets the specified thickness tolerance. Consider the GXT™ plating option if operating in environments with higher humidity or corrosive agents compared to standard tin or gold-only finishes.

Edgeboard Connectors Part Context

This part belongs to the EHPCE VR PF series, a line of vertical edge connectors designed for high-speed data transmission. The 10140903 base number indicates a dual-edge format, while the suffix -1220BLF specifies the 32-position count, black housing, and specific plating combination. This series is widely used in FCI's portfolio for demanding commercial and industrial electronic markets.

Edgeboard Connectors Replacement Considerations

Direct substitutes include other variants within the 10140903 family, such as 10140903-0416B2LF, provided the position count and mounting style match the design requirements. Cross-referencing pinout assignments and mechanical dimensions is essential when swapping between different suffixes in the same series.
