Edgeboard Connectors Procurement Notes

Verify the specific part number against official EDAC documentation to confirm compatibility with target PCB thickness and mounting requirements. Ensure that the procurement channel provides valid traceability and RoHS compliance certificates as required by project specifications. Cross-reference the manufacturer's latest datasheet to confirm availability status and any potential obsolescence notices before finalizing orders.

Edgeboard Connectors Selection Notes

Select this component when a dual-row card edge interface with 3.96 mm pitch is required for panel-mounted applications. The 56-position count suits moderate density needs, while the 5 A rating supports standard power distribution. Verify that the host enclosure accommodates the vertical profile and that the PCB design aligns with the specified 1.57 mm thickness tolerance for proper mating.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series of standard card edge connectors, which are engineered for robust performance in demanding environments. The series offers various position counts and mounting options, providing flexibility for diverse electronic assemblies. The 305-056-520-203 variant specifically addresses applications requiring dual-sided connectivity with reliable thermal and electrical characteristics.

Edgeboard Connectors Replacement Considerations

Consult the EDAC 305 Series Ordering Guide for direct substitutes with differing position counts or mounting styles. Verify that alternative parts maintain identical 3.96 mm pitch and 1.57 mm board thickness compatibility to ensure mechanical fit without redesigning the host PCB layout.
