305-080-500-258

Edgeboard Connectors Overview

The EDAC Inc. 305-080-500-258 is a standard card edge connector from the 305 series, designed for dual-edge board applications. It features 80 positions with a 0.156-inch (3.96 mm) pitch and accepts card thicknesses between 0.054 and 0.070 inches. The connector utilizes gold-plated copper alloy contacts with a 10.0 µin thickness and offers a 5 A continuous current rating. It supports 1800 VACrms insulation voltage and operates within a temperature range of -40°C to 105°C.

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix to confirm contact finish thickness and flange characteristics. Ensure compatibility with the target PCB card thickness range of 0.054 to 0.070 inches. Confirm that the required polarizing key configuration matches the system design constraints before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge card edge connector with a 3.96 mm pitch is required. The 5 A current rating and 1800 VACrms insulation voltage make it suitable for robust industrial environments. Consider the available polarizing key options if mechanical locking against the card edge is necessary for the application.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series is known for providing versatile interconnect solutions for various electronic assemblies. EDAC, now part of Northern Technologies, has provided these components since 1966, focusing on high-quality connectivity for global markets.

Edgeboard Connectors Replacement Considerations

Direct substitutes include other EDAC 305 series variants with matching 80-position counts and 3.96 mm pitch. Verify equivalent electrical ratings and mechanical mounting styles when considering alternative part numbers from the same manufacturer family.
