305-046-555-202

Edgeboard Connectors Overview

The EDAC Inc. 305-046-555-202 is a standard card edge connector featuring 46 positions arranged in a dual row configuration. It utilizes a 3.96 mm (0.156 inch) contact spacing and is designed for PCBs with a nominal thickness of 1.57 mm (0.062 inch). The connector employs gold-plated copper alloy contacts with a half-beam termination style, rated for 5 A current. It supports panel mounting at a vertical angle and operates within a temperature range of -40°C to +105°C.

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against official EDAC documentation to confirm exact pin count, plating thickness, and termination type. Ensure compatibility with target PCB thickness specifications before procurement. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process. Cross-reference datasheet revisions to avoid obsolete variants.

Edgeboard Connectors Selection Notes

Select this component when a dual-row card edge interface with 3.96 mm pitch is required. Verify that the host board accommodates the specified 1.57 mm thickness constraint. Ensure the application environment falls within the -40°C to +105°C operational range. Confirm that the 5 A current rating meets the circuit load requirements without derating.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and termination options. It is engineered for robust mechanical stability and electrical performance in demanding environments. The 305 series is widely used in industrial and commercial applications requiring reliable board-to-board or board-to-backplane connections.

Edgeboard Connectors Replacement Considerations

Direct substitutes include other EDAC 305 series parts with matching 46-position dual-row configurations and identical 3.96 mm pitch. Verify mechanical dimensions and termination style compatibility before substitution. Generic equivalents may lack the specific half-beam contact geometry required for optimal retention.
