306-020-520-103

Overview

The EDAC Inc. 306-020-520-103 is a standard card edge connector designed for vertical panel mounting applications. This component features a dual female configuration with 40 positions and a contact spacing of 0.156 inches (3.96 mm). It is engineered to accept printed circuit boards with a nominal thickness of 0.062 inches (1.57 mm). The contacts are constructed from copper alloy and feature gold plating to ensure reliable signal transmission. The insulator body is made of thermoplastic material, providing structural integrity and electrical insulation.

Feature Summary

• Dual female contact configuration for secure board insertion
• Gold-plated copper alloy contacts for enhanced conductivity
• Vertical panel mount design with low profile insulator body
• Compatible with standard 0.062 inch thick PCBs

Applications

• Industrial control system interconnects
• Telecommunications equipment backplanes
• Test and measurement instrument modules
• Computing hardware peripheral interfaces

Procurement Notes

Verify the specific ordering suffix against the official EDAC datasheet to confirm pin count, contact type, and mounting style. Ensure the target application requires a dual-edge female connector compatible with 0.062-inch board thickness. Confirm RoHS compliance status if environmental regulations apply to the final assembly. Cross-reference the part number with current manufacturer documentation to avoid obsolete variants.

Selection Notes

Select this connector when a high-density interface with 40 positions is required for vertical panel integration. The 3.96 mm pitch allows for compact layout designs while maintaining adequate spacing. Consider the gold plating requirement for environments demanding low contact resistance and corrosion resistance. Evaluate the mechanical stability provided by the panel mount style versus board mount alternatives for the specific chassis constraints.

Part Context

This component belongs to the EDAC 306 series of standard card edge connectors. The series offers various position counts and mounting options to support diverse electronic packaging needs. The 306 series is characterized by its robust construction and compatibility with standard industry PCB dimensions. It serves as a critical interface solution in modular electronic systems requiring reliable physical and electrical connections.

Replacement Considerations

Direct substitutes include other EDAC 306 series parts with matching 40-position dual female configurations. Verify that alternative components maintain the same 0.156-inch pitch and 0.062-inch board thickness compatibility. Check for identical mounting styles and contact materials to ensure functional equivalence without redesigning the host assembly.
