305-042-555-204

Edgeboard Connectors Overview

The EDAC Inc. 305-042-555-204 is a standard card edge connector from the 305 series, designed for dual-edge board insertion. It features 42 positions with a 0.156-inch (3.96 mm) pitch across two rows. The connector utilizes female half-beehive contacts made of copper alloy with gold plating. It supports PCB thicknesses between 0.054 and 0.070 inches (1.37 to 1.78 mm). Rated for 5 A current, it operates within a temperature range of -40°C to +105°C. The housing is green thermoplastic polyester, and it employs solder pin termination for panel mounting.

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against the official EDAC ordering guide to confirm exact contact length, flange style, and termination type. Ensure the selected variant matches the required PCB thickness tolerance and current rating specifications for the target application environment. Cross-reference the manufacturer part number with distributor catalogs to confirm availability status and compliance certifications such as RoHS3.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge card interface with a 3.96 mm pitch is required. Confirm that the host PCB thickness falls within the 1.37 mm to 1.78 mm operational window. Verify that the mating card edge geometry aligns with the half-beehive contact profile. Ensure the environmental conditions do not exceed the specified thermal limits for the thermoplastic housing material.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and termination options. The 305-042-555-204 specifically denotes a 42-position dual-edge female connector with gold plating and thermoplastic insulation, suitable for high-reliability industrial applications requiring robust mechanical retention.

Edgeboard Connectors Replacement Considerations

Consult the EDAC 305 series ordering guide for direct substitutes with identical pitch and position counts. Verify compatibility with existing PCB layouts and mating card dimensions before substitution.
