Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against official EDAC documentation to ensure correct termination type and plating specifications. Confirm that the target application requires the 3.96 mm pitch and 1.57 mm board thickness compatibility. Check regional availability as distribution status may vary by location.

Edgeboard Connectors Selection Notes

Select this component when a high-density 56-position connection is required for double-sided cards. Ensure the mechanical design accommodates the vertical panel mount style and solder lug termination method. Verify that the operating environment falls within the specified -40°C to +105°C temperature range.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series provides various position counts and termination options for industrial applications. The 305-056 variant specifically addresses needs for moderate pin counts with durable metal housing characteristics.

Edgeboard Connectors Replacement Considerations

Cross-reference with other EDAC 305 series parts such as 305-056-500-207 or 305-056-520-201 if different termination styles are needed. Ensure substitute parts maintain the same 3.96 mm pitch and 1.57 mm board thickness compatibility.
