305-042-500-203

Edgeboard Connectors Overview

The EDAC Inc. 305-042-500-203 is a standard card edge connector from the 305 series, designed for dual female connections with 42 positions. It features a 3.96 mm (0.156 inch) pitch and supports board thicknesses ranging from 1.37 mm to 1.78 mm. The connector utilizes gold-plated copper alloy contacts with a 10.0 µin (0.25 µm) plating thickness, ensuring reliable signal transmission. Rated for 5 A current, it operates within a temperature range of -40°C to +105°C. The housing is made of green thermoplastic polyester, providing robust insulation with a minimum resistance of 5 GOhms.

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm exact contact type, flange features, and termination style. Ensure compatibility with the target PCB thickness range of 1.37 mm to 1.78 mm. Confirm RoHS compliance status if required by project specifications. Cross-reference the part number with authorized distributors to avoid counterfeit components. Check for any regional distribution restrictions or lead time variations before finalizing procurement plans.

Edgeboard Connectors Selection Notes

Select this component when a dual-row, 42-position card edge connector with a 3.96 mm pitch is required. It is suitable for applications demanding a 5 A current rating and operation between -40°C and +105°C. Choose this model for panel-mount installations where flush mounting is preferred. Ensure the mating card thickness falls within the specified 1.37 mm to 1.78 mm range. Consider the gold plating thickness for long-term reliability in harsh environments.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors, which are widely used in industrial and commercial electronics. The series offers various position counts and mounting styles to accommodate different design requirements. The 305-042-500-203 specifically provides a balanced solution for medium-density connections with robust mechanical and electrical characteristics.

Edgeboard Connectors Replacement Considerations

Direct substitutes may include other EDAC 305 series parts with matching 42 positions and 3.96 mm pitch, such as 305-042-520-202, provided flange and termination details align. Verify that alternative models support the same board thickness and current rating. Consult the manufacturer's cross-reference guide for approved replacements.
