305-084-556-258

Edgeboard Connectors Overview

The EDAC Inc. 305-084-556-258 is a standard card edge connector header from the 305 series, designed for vertical panel mounting applications. It features a dual-row configuration with 84 positions and a contact spacing of 3.96 mm (0.156 inches). The connector utilizes gold-plated copper alloy contacts with solder pin termination to ensure reliable electrical connections. It is engineered to accept printed circuit boards with a nominal thickness of 1.57 mm (0.062 inches). The insulator body is constructed from thermoplastic material, providing structural integrity and electrical insulation. This component supports a current rating of 5 A and operates within a temperature range of -40°C to +105°C.

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the official EDAC datasheet to confirm exact plating thickness, contact length, and flange specifications. Ensure compatibility with target PCB thickness tolerances before procurement. Confirm RoHS compliance status through manufacturer documentation. Check for any regional distribution restrictions or supply limitations that may affect availability. Validate mechanical dimensions against enclosure requirements.

Edgeboard Connectors Selection Notes

Select this connector when a high-density dual-row interface is required for 1.57 mm thick boards. The 3.96 mm pitch allows for robust signal routing in space-constrained panels. Consider the 5 A current rating for power distribution needs. Evaluate the vertical mounting style against available panel space. Compare alternative part numbers in the 305 series if different position counts or row configurations are needed.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series of standard card edge connectors, which are widely used in industrial and commercial applications requiring reliable board-to-board or board-to-panel connections. The series offers various position counts and mounting styles to accommodate diverse design requirements. The 305-084 variant specifically addresses high-pin-count applications needing stable vertical integration.

Edgeboard Connectors Replacement Considerations

Consult the EDAC 305 series ordering guide for direct substitutes with differing position counts or flange options. Verify that any replacement maintains the 3.96 mm pitch and 1.57 mm board thickness compatibility. Cross-reference mechanical drawings to ensure mounting hole patterns and overall dimensions match existing panel designs.
