Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against official EDAC documentation to confirm exact plating thickness and material specifications. Ensure compatibility with target PCB dimensions, particularly the 1.57 mm nominal thickness requirement. Confirm that the vertical panel mount style aligns with mechanical enclosure constraints before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this model when a 78-position dual-row interface is required with a 3.96 mm spacing. It is suitable for designs demanding vertical orientation and panel installation. Consider the 5 A current rating and thermal limits when evaluating system power requirements. Verify that the solder pin termination method matches the assembly process capabilities.

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 pitch standards. These connectors are engineered for general-purpose electronic applications requiring reliable interconnection between edgeboard modules and base circuits.

Edgeboard Connectors Replacement Considerations

Cross-reference part numbers within the EDAC 305 series for alternative position counts. Verify mechanical footprint and pinout compatibility before substituting with similar connectors from other manufacturers. Ensure that any replacement maintains the same pitch, row count, and mounting style requirements.
