10140903-1420ALF

Edgeboard Connectors Overview

The Amphenol ICC (FCI) 10140903-1420ALF is a dual-edge card edge connector designed for press-fit termination. It features 34 positions, configured as 20 signal and 14 power contacts, arranged in two rows. The connector utilizes female contacts made of copper alloy with a blue thermoplastic glass fiber insulation body. It supports a board thickness of 0.062 inches (1.57mm) and is intended for through-hole mounting on non-specified dual-edge cards.

Edgeboard Connectors Feature Summary

• Dual-edge configuration supporting both sides of the circuit board
• Press-fit termination method for secure PCB attachment
• Integrated power and signal contact arrangement

Edgeboard Connectors Applications

• High-density backplane interconnects
• Industrial control system modules
• Telecommunications infrastructure equipment

Edgeboard Connectors Procurement Notes

Verify the specific suffix ALF against the manufacturer's current datasheet to confirm lead-free compliance status. Ensure the ordering part number matches the required pin count and row configuration. Confirm that the target application board thickness aligns with the specified 0.062-inch requirement for proper mechanical engagement.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge card interface with mixed signal and power distribution is required. The press-fit termination offers robust mechanical stability without soldering thermal stress. Consider the 34-position capacity and dual-row layout for space-constrained high-pin-count applications requiring reliable vertical insertion.

Edgeboard Connectors Part Context

This model belongs to the 10140903 series of card edge connectors from Amphenol ICC. The series provides various position counts and configurations for different board edge types. This specific variant focuses on dual-edge compatibility with a balanced mix of signal and power pins for complex module connections.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include variants like 10140903-0416B2LF or 10140903-1420ALF equivalents. Verify identical row count, total position number, and termination style before substitution. Cross-reference mechanical dimensions to ensure board slot compatibility.
