Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm exact physical dimensions and plating specifications. Ensure compatibility with the target PCB thickness of 1.57 mm before procurement. Confirm that the panel mount style aligns with the mechanical enclosure requirements of the final assembly.

Edgeboard Connectors Selection Notes

Select this component when a vertical, panel-mount solution is required for dual-edge card applications. The 3.96 mm pitch suits high-density layouts where larger spacing aids manufacturing tolerance. Verify that the 5 A current rating meets the circuit load requirements and that the -40°C to +105°C operating temperature range covers the environmental conditions.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and mounting styles, utilizing a consistent 3.96 mm contact spacing. The 305 series is characterized by its robust thermoplastic housing and reliable solder pin termination, widely used in industrial and commercial electronics for durable board-to-board or board-to-panel connections.

Edgeboard Connectors Replacement Considerations
