305-012-520-203

Edgeboard Connectors Overview

The EDAC Inc. 305-012-520-203 is a standard card edge connector from the 305 series, designed for dual female mating with printed circuit boards. It features 12 positions arranged in a single row with a 3.96 mm (0.156 inch) pitch. The connector supports a maximum operating temperature of +105°C and a minimum of -40°C. Electrical specifications include a current rating of 5 A and an insulation resistance of 5 GOhms. The contacts are made of copper alloy with gold plating, housed in a thermoplastic body.

Edgeboard Connectors Feature Summary

• Dual female contact configuration for secure card edge board insertion
• Gold-plated copper alloy contacts ensure reliable signal transmission
• Thermoplastic housing provides structural integrity and electrical insulation
• Panel mount installation style with vertical orientation

Edgeboard Connectors Applications

• Industrial control panel interconnections
• Embedded system module interfaces
• Telecommunications equipment backplanes

Edgeboard Connectors Procurement Notes

Verify that the specific part number matches the required 12-position count and 3.96 mm pitch before ordering. Confirm RoHS compliance status through official manufacturer documentation or authorized distributors. Ensure the receiving facility has appropriate handling procedures for sensitive electronic components to prevent electrostatic discharge damage during storage and assembly.

Edgeboard Connectors Selection Notes

Select this component when a single-row, 12-position interface is required with a 3.96 mm spacing. It is suitable for applications demanding a 5 A current capacity and operation within a -40°C to +105°C range. Consider the panel mount style and solder pin termination method for integration into the target PCB design.

Edgeboard Connectors Part Context

This connector belongs to the EDAC 305 series, which offers various position counts and configurations. Similar parts in the series include the 305-038-520-502 and 305-040-520-203, which share the same pitch and general electrical characteristics but differ in the number of positions. The series is characterized by its robust thermoplastic construction and gold-plated contacts.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the EDAC 305 series must maintain the 12-position count and 3.96 mm pitch. Verify compatibility with existing PCB layouts and mating card edge thicknesses. Cross-reference with other manufacturers only if mechanical dimensions and electrical ratings are identical.
