305-046-556-203

Edgeboard Connectors Overview

The EDAC Inc. 305-046-556-203 is a standard card edge connector featuring 46 positions in a dual-row configuration. It utilizes a 3.96 mm (0.156 inch) contact spacing and accepts printed circuit boards with a nominal thickness of 1.57 mm (0.062 inch). The connector employs gold-plated copper alloy contacts rated for 5 A current. Designed for panel mounting, it offers vertical termination via solder pins. The insulator body is constructed from thermoplastic material, providing an operating temperature range from -40°C to +105°C.

Edgeboard Connectors Procurement Notes

Verify the specific manufacturer part number against official EDAC documentation to confirm compatibility with your board stack-up. Ensure that the required contact spacing and row configuration match your design specifications before procurement. Cross-reference the datasheet for environmental ratings to confirm suitability for your operational temperature range.

Edgeboard Connectors Selection Notes

Select this component when a dual-row card edge interface with 3.96 mm pitch is required for panel-mounted applications. Consider the 5 A current rating and gold plating for durability in industrial environments. Verify that the target PCB thickness aligns with the 1.57 mm specification to ensure proper mechanical retention and electrical contact.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series of standard card edge connectors. The series is characterized by robust construction suitable for high-reliability applications. The specific model indicates a 46-position variant within this family, sharing common form factors with other parts in the series while differing in position count.

Edgeboard Connectors Replacement Considerations

Consult EDAC official documentation for direct substitute part numbers within the 305 series. Verify that any alternative maintains identical pin count, pitch, and mounting style to ensure mechanical and electrical compatibility without redesigning the host PCB.
