305-028-500-502

Edgeboard Connectors Overview

The EDAC Inc. 305-028-500-502 is a standard card edge connector designed for vertical panel mounting applications. It features a dual-edge female configuration with 28 positions and a contact spacing of 0.156 inches (3.96 mm). The connector utilizes gold-plated copper alloy contacts with a solder lug termination type to ensure reliable electrical connections. It accommodates printed circuit boards with a nominal thickness of 0.062 inches (1.57 mm) and provides a continuous current rating of 5 A. The housing is constructed from thermoplastic material, offering durability in industrial environments.

Edgeboard Connectors Procurement Notes

Verify the exact part number against official EDAC documentation to confirm compatibility with your specific PCB thickness and mounting constraints. Ensure that the required current rating aligns with your system's operational demands. Check for any recent product change notifications or obsolescence notices directly from the manufacturer before finalizing procurement decisions.

Edgeboard Connectors Selection Notes

Select this component when a vertical panel-mount solution with a 3.96 mm pitch is required. Confirm that the target PCB thickness matches the 1.57 mm specification to ensure proper engagement. Evaluate the need for gold plating versus other finishes based on environmental exposure and cycle life expectations compared to alternative series options.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 Series, which offers a range of card edge connectors with varying position counts and termination styles. The series is characterized by its standardized dimensions and reliable performance in demanding applications. This specific model represents a mid-range position count option within the broader family of dual-edge connectors.

Edgeboard Connectors Replacement Considerations

Consult the official EDAC cross-reference guide for verified substitute part numbers. Direct replacements must maintain identical pin counts, pitch, and mounting characteristics to ensure mechanical and electrical compatibility without redesigning the host assembly.
