305-046-521-202

Edgeboard Connectors Overview

The EDAC Inc. 305-046-521-202 is a standard card edge connector featuring 46 positions arranged in a dual-row configuration. It utilizes a 3.96 mm (0.156 inch) pitch and is designed for vertical panel mounting. The connector supports a board thickness of 1.57 mm and employs gold-plated copper alloy contacts with solder pin termination. Rated for 5 A current, it operates within a temperature range of -40°C to +105°C and includes a green thermoplastic housing.

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against official EDAC documentation to confirm exact plating thickness, housing color, and termination style variations. Ensure compatibility with target PCB edge card dimensions and panel cutout requirements before procurement. Cross-reference RoHS compliance status with the latest manufacturer declarations.

Edgeboard Connectors Selection Notes

Select this component when a dual-row interface with a 3.96 mm pitch is required for high-current applications up to 5 A. Consider the vertical mounting profile and 1.57 mm board thickness constraint during mechanical design. Evaluate the operating temperature range against environmental conditions to ensure reliability within the specified -40°C to +105°C limits.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and row configurations. The 305-046 variant specifically provides 46 positions, balancing density and spacing for modular electronic assemblies requiring robust mechanical and electrical connections.

Edgeboard Connectors Replacement Considerations

Direct substitutes include other EDAC 305 series parts with matching 46-position dual-row specifications, such as 305-046-500-202 or 305-046-521-278, provided pitch and mounting style align.
