Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against official EDAC documentation to ensure correct contact plating and termination type compatibility. Confirm that the target PCB thickness matches the 1.57 mm specification to guarantee proper mechanical retention. Check RoHS compliance status through the manufacturer's latest datasheet before final procurement decisions.

Edgeboard Connectors Selection Notes

Select this component when a high-current 5A connection is required for thick PCBs up to 1.57 mm. The 3.96 mm spacing allows for robust signal integrity in industrial environments. Ensure the application supports vertical panel mounting and utilizes compatible polarizing keys for secure assembly.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of card edge connectors, which are characterized by their .156 inch (3.96mm) contact spacing. The series is engineered for durability and reliable performance in demanding electronic applications requiring secure board-to-board or backplane connections.

Edgeboard Connectors Replacement Considerations

Consult EDAC official substitution lists for direct replacements. Verify that any alternative maintains the 3.96 mm pitch, 40-position count, and 1.57 mm board thickness compatibility.
