305-080-556-204

Edgeboard Connectors Overview

The EDAC Inc. 305-080-556-204 is a dual-edge female card edge connector designed for board-to-board interconnection. It features 80 positions arranged in two rows with a 0.156-inch (3.96mm) pitch. The connector utilizes gold-plated copper alloy contacts and a green thermoplastic polyester insulator. It supports PCB thicknesses between 0.054 and 0.070 inches and operates within a temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Dual-edge female configuration for non-specified dual-edge cards
• Gold-plated semi-crimped contact type for reliable signal transmission
• Straddle mount installation style for secure board attachment
• Card extender feature facilitating adapter board applications

Edgeboard Connectors Procurement Notes

Verify the specific suffix code against official EDAC documentation to ensure correct flange and termination specifications. Confirm that the required PCB thickness falls within the supported range of 0.054 to 0.070 inches. Check RoHS compliance status and lead times directly with authorized distributors, as availability may vary by region.

Edgeboard Connectors Selection Notes

Select this component when a dual-row, 80-position interface with a 3.96mm pitch is required. Ensure the mating card is a non-specified dual-edge type compatible with the 0.156-inch contact length. Consider the straddle mount requirement for mechanical stability during operation.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 Series, which provides standard card edge connectors. The series offers various position counts and mounting options. The 305-080 variant specifically addresses high-density connection needs with its 80-position layout.

Edgeboard Connectors Replacement Considerations

Direct substitutes are not explicitly listed in public data. Verify compatibility with existing board layouts and mating card specifications before considering alternative part numbers from the same manufacturer or series.
