305-022-520-202

Edgeboard Connectors Overview

The EDAC Inc. 305-022-520-202 is a dual-edge female card edge connector designed for panel and through-hole mounting. It features 22 positions with a 0.156-inch (3.96mm) pitch across two rows. The contacts are made of copper alloy with gold plating, specifically half-beehive type, ensuring reliable signal transmission. The insulator is constructed from green thermoplastic polyester, supporting board thicknesses between 0.054 and 0.070 inches. Rated for operation from -40°C to 105°C, it utilizes solder pin termination for secure PCB attachment.

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official 305 Series Ordering Guide to ensure correct contact tail length and flange specifications. Confirm RoHS3 compliance status and lead times directly with authorized distributors, as availability may vary by region. Cross-reference the DigiKey part number 151-305-042-520-202-ND if sourcing through that channel, though standard identification remains 305-022-520-202.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge female connector with a 3.96mm pitch is required for vertical panel mounting. Ensure the target printed circuit board thickness falls within the 1.37mm to 1.78mm range for proper insertion. Consider the operating temperature range of -40°C to 105°C for environmental suitability. Verify that the gold contact plating meets the necessary corrosion resistance requirements for the application environment.
