306-020-421-108

Edgeboard Connectors Overview

The EDAC Inc. 306-020-421-108 is a standard card edge connector from the 306 series, designed for panel mount applications with a vertical orientation. It features a dual female configuration with 40 positions and a pitch of 3.96 mm (0.156 inches). The connector supports a board thickness of 1.57 mm and utilizes copper alloy contacts with gold plating to ensure reliable signal transmission. Rated for 5 A current, it employs solder pin termination for secure PCB attachment. The housing is constructed from thermoplastic polyester, providing durability in industrial environments.

Edgeboard Connectors Feature Summary

• Dual-edge female contact configuration for non-specified card edge boards
• Gold-plated copper alloy contacts for enhanced conductivity and corrosion resistance
• Thermoplastic polyester housing material for structural stability
• Vertical panel mount design with solder pin termination

Edgeboard Connectors Applications

• Industrial control systems requiring robust interconnects
• Panel-mounted electronic assemblies needing high-current capacity
• General-purpose circuit board interfacing in harsh environments

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm contact plating and housing color variations. Ensure compatibility with the target PCB stack-up and mounting hole dimensions. Confirm that the 5 A current rating aligns with the application's thermal requirements. Check for RoHS compliance status if environmental regulations apply to the end product.

Edgeboard Connectors Selection Notes

Select this component when a vertical, panel-mount solution is required for dual-edge cards. The 3.96 mm pitch accommodates larger spacing needs compared to finer pitches. Verify that the 1.57 mm board thickness matches the design specifications. Consider the gold plating for longevity in high-cycle or corrosive conditions where silver or tin might degrade.

Edgeboard Connectors Part Context

This part belongs to the EDAC 306 series of standard card edge connectors. The series is characterized by its use of thermoplastic polyester housings and copper alloy contacts. The 306 series offers various position counts and mounting styles, catering to diverse industrial and commercial interconnect needs. This specific model represents a mid-range position count within the series.

Edgeboard Connectors Replacement Considerations

Direct substitutes may include other EDAC 306 series variants with matching 40-position dual-edge configurations. Cross-brand replacements require verification of pitch, board thickness, and mounting style compatibility. Ensure any alternative maintains the 5 A current rating and vertical panel mount form factor.
