305-046-556-558

Edgeboard Connectors Overview

The EDAC 305-046-556-558 is a standard card edge connector header from the 305 series. It features a dual-row configuration with 46 positions and a contact pitch of 3.96 mm (0.156 inches). The row spacing is 3.56 mm, designed to accept printed circuit boards with a nominal thickness of 1.57 mm (0.062 inches). The contacts are constructed from copper alloy with gold plating, rated for 5 A current. The insulator body is green thermoplastic polyester, providing an insulation resistance of 5 GOhms. Operating temperature ranges from -40°C to +105°C.

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against official EDAC documentation to confirm exact termination style and mounting variations. Ensure compatibility with target PCB thickness specifications before procurement. Confirm RoHS compliance status through manufacturer datasheets. Validate that the selected variant matches the required panel or board mount orientation for the intended assembly.

Edgeboard Connectors Selection Notes

Select this component when a 3.96 mm pitch dual-row connection is required for 0.062-inch thick circuit boards. Consider the 5 A current rating and thermal limits for power distribution needs. Evaluate the vertical mounting profile against available chassis space. Compare against single-row alternatives if fewer connections suffice for the application requirements.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of card edge connectors, which provides various mounting options and row configurations. The series utilizes a standardized 3.96 mm pitch to ensure interoperability across different module designs. The 305 series headers are engineered for high-density applications requiring robust mechanical retention and electrical stability in demanding environments.

Edgeboard Connectors Replacement Considerations

Consult EDAC directly for verified substitute part numbers within the 305 or 355 series. Cross-reference pin counts and pitch dimensions strictly. Verify that any alternative maintains the same PCB thickness tolerance and current rating specifications.
