305-028-520-501

Edgeboard Connectors Overview

The EDAC Inc. 305-028-520-501 is a standard card edge connector from the 305 series, designed for vertical panel mounting applications. It features a dual female configuration with 28 positions and a 3.96 mm (0.156 inch) pitch. The connector utilizes gold-plated copper alloy contacts and solder pin termination methods. It supports a continuous current rating of 5 A and withstands 1800 VACrms dielectric voltage. The unit accommodates board thicknesses ranging from 1.37 mm to 1.78 mm and operates within a temperature range of -40°C to +105°C.

Edgeboard Connectors Procurement Notes

Verify the specific suffix code against official EDAC documentation to confirm exact plating thickness and material specifications. Ensure compatibility with the target PCB stack-up regarding the specified 1.37 mm to 1.78 mm thickness range. Confirm that the vertical panel mount orientation aligns with the mechanical enclosure design requirements before finalizing the order.

Edgeboard Connectors Selection Notes

Select this component when a high-reliability card edge interface with a 3.96 mm pitch is required. The 5 A current rating suits power distribution needs alongside signal lines. The dual row layout maximizes I/O density within limited panel space. Verify that the operating environment stays within the -40°C to +105°C thermal limits for long-term stability.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 Series, a line of standard card edge connectors known for durability in harsh environments. The series offers various position counts and mounting styles. The 305-028-520-501 specifically addresses applications needing a 28-position dual-row interface with panel-mount flexibility and high dielectric strength.

Edgeboard Connectors Replacement Considerations

Consult the EDAC 305/315/355 Series Ordering Guide for direct substitutes. Cross-reference pitch, position count, and termination type. Generic equivalents may lack the specific polarizing key acceptance or 1800 VACrms rating.
