305-058-520-203

Edgeboard Connectors Overview

The EDAC 305-058-520-203 is a standard card edge connector from the 305 series, designed for panel mount applications. It features 58 positions arranged in a dual-row configuration with a contact spacing of 0.156 inches (3.96 mm). The connector utilizes gold-plated copper alloy contacts and a green thermoplastic insulator body. It supports a nominal printed circuit board thickness of 0.062 inches (1.57 mm) and offers a continuous current rating of 5 A. The unit employs solder pin termination and operates within a temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for secure alignment
• Features a low-profile insulator body with flanges for panel mounting
• Provides high dielectric strength with a 1800VACrms insulation capability

Edgeboard Connectors Applications

• Industrial control systems requiring polarized card edge connections
• Panel-mounted electronic modules needing robust thermal performance
• High-density interconnect applications utilizing standard PCB thicknesses

Edgeboard Connectors Procurement Notes

Verify that the specific part number matches the required position count and row configuration before ordering. Confirm that the receiving printed circuit board adheres to the specified nominal thickness of 0.062 inches to ensure proper mechanical engagement. Check regional availability as distribution status may vary by location. Ensure compliance with RoHS3 specifications if environmental regulations apply to the assembly process.

Edgeboard Connectors Selection Notes

Select this component when a dual-row card edge connector with polarizing key compatibility is required. The 3.96 mm pitch suits applications where larger spacing reduces crosstalk risks compared to finer pitches. The 5 A current rating supports moderate power distribution needs. Consider the vertical panel mount style if space constraints require a perpendicular connection orientation relative to the mating board.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series of standard card edge connectors. The series is characterized by its ability to accept polarizing keys and its suitability for panel mount installations. Similar parts in the series vary primarily by position count, such as the 305-050 or 305-038 variants, while maintaining consistent pitch and termination characteristics.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include the 305-050-520-203 and 305-038-520-502, which share identical electrical and mechanical specifications but differ in position count. Verify that any replacement maintains the dual-row configuration and 3.96 mm pitch to ensure compatibility with existing tooling and PCB layouts.
