Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against official EDAC documentation to confirm exact plating thickness, material grades, and environmental compliance status. Ensure that the selected variant matches the required PCB thickness tolerance of 1.57 mm. Confirm availability through authorized distributors as supply chain constraints may affect lead times. Cross-reference the datasheet for any recent updates regarding RoHS directives or halogen-free requirements before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this connector when a dual-row interface with 3.96 mm pitch is required for high-density applications. The 5 A current rating supports moderate power distribution needs. Verify compatibility with the target PCB stack-up and mechanical constraints. Consider the vertical mounting orientation and panel installation style during mechanical design integration. Ensure the operating temperature range meets the environmental demands of the intended deployment scenario.

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 to accommodate different signal density requirements. The 305 series is characterized by its robust construction and reliable performance in demanding electronic environments.
