305-078-500-204

Edgeboard Connectors Overview

The EDAC Inc. 305-078-500-204 is a standard card edge connector designed for panel mount applications with a vertical orientation. It features a dual female configuration with 78 positions and a pitch of 0.156 inches (3.96 mm). The contacts are gold-plated copper alloy, supporting a continuous current rating of 5 A and an insulation voltage of 1800 VACrms. The unit accepts between-contact and in-contact polarizing keys and is compatible with PCBs up to 1.57 mm thick.

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer datasheet to confirm pin count and termination style. Ensure compatibility with existing polarizing key requirements. Confirm that the target printed circuit board thickness falls within the specified mechanical limits before finalizing procurement decisions.

Edgeboard Connectors Selection Notes

Select this component when a high-position-count interface is required for vertical panel mounting. The 3.96 mm pitch accommodates larger signal traces compared to finer pitches. Verify that the 5 A current rating meets the load requirements of the connected circuitry and that the 1800 VACrms insulation rating satisfies safety standards.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of card edge connectors. The series offers various position counts and termination options. The 305-078-500-204 specifically provides a 78-position dual female interface. It is engineered for robust performance in demanding environments requiring stable electrical connections.

Edgeboard Connectors Replacement Considerations

Compatible substitutes include other EDAC 305 series variants with matching 78 positions and 3.96 mm pitch. Verify that alternative parts support the same vertical panel mount style and accept identical polarizing key configurations to maintain mechanical compatibility.
