Edgeboard Connectors Procurement Notes

Verify the specific part number against official EDAC documentation to confirm availability status and regional distribution restrictions. Ensure that the ordering suffix matches the required contact finish and housing color specifications. Confirm that the target application supports the specified 3.96 mm pitch and panel mounting style before finalizing procurement decisions.

Edgeboard Connectors Selection Notes

Select this component when a dual-row, 52-position card edge connector with a 3.96 mm pitch is required for vertical panel mounting. Ensure the mating PCB thickness falls within the 1.37 mm to 1.78 mm range. Consider the need for polarizing key compatibility if precise alignment is critical for the assembly process.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and row configurations while maintaining consistent 3.96 mm spacing. These connectors are designed for robust industrial applications requiring high reliability and precise mechanical alignment through optional polarizing features.

Edgeboard Connectors Replacement Considerations

Cross-reference with other EDAC 305 series variants such as 305-050-556-207 or 305-054-556-278 for similar form factors. Verify that any substitute maintains the same 3.96 mm pitch, dual-row layout, and panel mount orientation to ensure mechanical and electrical compatibility.
