305-078-520-202

Edgeboard Connectors Overview

The EDAC 305-078-520-202 is a standard card edge connector receptacle featuring 78 positions arranged in two rows. 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 contacts are constructed from copper alloy with gold plating, rated for 5 A current at an insulation resistance of 5 GOhms. Designed for PCB mount installation with straight orientation, the housing is made of green thermoplastic polyester. The component operates within a temperature range of -40°C to +105°C and employs solder termination.

Edgeboard Connectors Procurement Notes

Verify the complete part number against official EDAC documentation to confirm specific suffix requirements. Ensure that the procurement source provides valid RoHS compliance data and original manufacturer certification. Cross-reference the pin count and row configuration with system design specifications before ordering to prevent compatibility issues with target circuit boards.

Edgeboard Connectors Selection Notes

Select this component when a 78-position dual-row interface is required for 1.57 mm thick PCBs. The 3.96 mm pitch dictates compatible card edge dimensions. Consider the straight PCB mount style and solder termination method for assembly processes. Verify that the operating temperature range and current ratings align with the electrical environment of the target application.
