305-012-556-203

Edgeboard Connectors Overview

The EDAC Inc. 305-012-556-203 is a standard card edge connector featuring 12 positions in a dual female configuration. It utilizes a 3.96 mm (0.156 inch) pitch and is designed for non-specified dual-edge cards. The connector employs gold-plated copper alloy contacts with a solder pin termination type. It supports a current rating of 5 A and operates within a temperature range of -40°C to +105°C. The housing is constructed from green thermoplastic polyester, ensuring reliable insulation and mechanical stability for panel or PCB mounting applications.

Edgeboard Connectors Feature Summary

• Dual female contact configuration for secure dual-edge card insertion
• Gold-plated copper alloy contacts ensure low resistance and corrosion resistance
• Thermoplastic polyester housing provides thermal stability and insulation
• Solder pin termination facilitates direct board attachment

Edgeboard Connectors Applications

• Industrial control system interface modules
• Telecommunications equipment backplanes
• Test and measurement instrument card connections
• Automotive electronic control unit interfaces

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against the manufacturer's official ordering guide to confirm exact plating thickness and housing color variations. Confirm that the target application requires a dual-edge connector design rather than single-edge alternatives. Ensure compatibility with the specified 3.96 mm pitch and 1.57 mm board thickness constraints before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge connection is required for signal integrity in high-density layouts. The 5 A current rating suits moderate power distribution needs. Verify that the operating environment stays within the -40°C to +105°C range. Consider the vertical or straight mounting orientation based on the chassis design requirements.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and mounting styles. The 305-012 variant specifically addresses compact dual-edge applications requiring robust gold-plated contacts. It complements other series members by providing standardized dimensions for interoperability.

Edgeboard Connectors Replacement Considerations

Direct substitutes include EDAC 305-012-556-201 and 305-012-556-208, which share identical electrical and mechanical specifications. Cross-brand replacements require verification of pitch, contact configuration, and mounting hole alignment.
