305-062-520-203

Edgeboard Connectors Overview

The EDAC Inc. 305-062-520-203 is a standard card edge connector from the 305 series, designed for panel mount and through-hole installation. It features a dual-row configuration with 62 positions and a pitch of 3.96 mm (0.156 inches). The connector supports board thicknesses ranging from 1.37 mm to 1.78 mm. Contacts are made of copper alloy with gold plating, rated for 5 A current. The insulator is green thermoplastic polyester, operating between -40°C and +105°C.

Edgeboard Connectors Feature Summary

• Dual-edge female contact design for non-specified card types
• Gold-plated copper alloy contacts ensure reliable signal transmission
• Thermoplastic polyester insulator provides thermal stability
• Panel mount style with solder pin termination

Edgeboard Connectors Applications

• Industrial control system backplanes
• Telecommunications equipment interconnects
• Test and measurement instrument modules
• Embedded computing board interfaces

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the official EDAC 305 Series Ordering Guide to confirm exact contact tail length and flange dimensions. Ensure compatibility with target PCB thickness within the 1.37 mm to 1.78 mm range. Confirm RoHS compliance status for the specific batch if required by project specifications.

Edgeboard Connectors Selection Notes

Select this model when a dual-row, 3.96 mm pitch connector is required for vertical panel mounting. Compare against the 315 and 355 series if different contact tail lengths or insulator heights are needed. Ensure the application does not require single-edge connectivity, as this part is strictly dual-edge.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305/315/355 family of standard card edge connectors. These series share common pitch and mounting characteristics but differ in physical dimensions such as contact tail length and insulator height. The 305 series specifically denotes standard tail lengths suitable for general-purpose panel mount applications.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include 305-062-520-502 or 305-062-520-508, depending on required termination type variations. Cross-series replacements like 315-062-520-203 may be considered if different insulator heights are acceptable.
