305-074-520-203

Edgeboard Connectors Overview

The EDAC Inc. 305-074-520-203 is a standard card edge connector featuring 74 positions in a dual female configuration. It utilizes a 3.96 mm (0.156 inch) pitch and supports board thicknesses ranging from 1.37 mm to 1.78 mm. The connector employs gold-plated copper alloy contacts with a solder termination type for reliable electrical connections. Designed for panel mounting, this component operates within a temperature range of -40°C to +105°C and carries an insulation resistance rating of 5 GOhms.

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against official EDAC documentation to confirm exact plating thickness and material specifications. Ensure compatibility with target PCB dimensions and mounting hardware requirements before procurement. Cross-reference RoHS compliance status with current regulatory standards applicable to your region.

Edgeboard Connectors Selection Notes

Select this model when a dual-edge female connector with a 3.96 mm pitch is required for panel-mounted applications. Consider the 74-position count and specified thermal operating range. Confirm that the thermoplastic polyester housing meets environmental exposure needs for the intended deployment scenario.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and mounting styles. The 305-074-520-203 variant specifically addresses high-pin-count requirements with a dual-edge interface, distinguishing it from single-edge or lower-count alternatives within the same product family.

Edgeboard Connectors Replacement Considerations

Direct substitutes include other EDAC 305 series parts with matching 74-position dual female configurations. Verify identical pitch, board thickness tolerance, and termination style. Alternative manufacturers may offer compatible components if mechanical and electrical parameters align precisely.
