306-021-520-108

Overview

The EDAC Inc. 306-021-520-108 is a standard card edge connector featuring 42 positions arranged in a dual-row configuration. It utilizes a 0.156-inch (3.96 mm) pitch with copper alloy contacts plated in gold. Designed for non-specified dual-edge cards, the unit supports a current rating of 5 A and operates within a temperature range of -40°C to +105°C. The housing is constructed from green thermoplastic material, providing an insulation resistance of 5 GOhms. This vertical panel-mount component ensures reliable electrical interconnection for board-to-board applications.

Feature Summary

• Dual-edge female contact design accommodates non-specified card thicknesses
• Gold-plated copper alloy contacts ensure low resistance and corrosion resistance
• Vertical panel mount style provides secure structural installation
• Thermoplastic insulator offers high dielectric strength and thermal stability

Applications

• Industrial automation control systems
• Embedded computing modules
• Telecommunications infrastructure equipment
• Medical diagnostic devices

Procurement Notes

Verify the specific ordering suffix against official EDAC documentation to confirm exact pin count, plating thickness, and flange specifications. Ensure compatibility with target PCB panel mounting requirements and card edge thickness tolerances before finalizing procurement orders.

Selection Notes

Select this connector when dual-row vertical mounting is required for standard card edge interfaces. Verify that the 0.156-inch pitch aligns with the mating card layout. Confirm that the thermoplastic housing material meets the environmental operating temperature requirements of the target application.

Part Context

This component belongs to the EDAC 306 series of standard card edge connectors. The series is characterized by robust construction for industrial environments. The 306 series offers various position counts and mounting styles to support diverse electronic system integration needs across multiple hardware platforms.

Replacement Considerations

Consult official EDAC substitution guides for verified equivalent part numbers. Cross-reference pitch, row count, and mounting style to ensure mechanical and electrical compatibility without redesigning the host assembly.
