Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against official EDAC documentation to confirm exact plating thickness and flange characteristics. Ensure compatibility with the target PCB thickness of 1.57 mm before procurement. Confirm RoHS3 compliance status through the manufacturer's latest datasheet. Cross-reference the Mouser or DigiKey part numbers for accurate identification during sourcing. Validate that the vertical mounting style aligns with the mechanical enclosure requirements.

Edgeboard Connectors Selection Notes

Select this connector when a dual-row layout with a 3.96 mm pitch is required for vertical panel installation. The 12-position count suits applications needing moderate I/O density within a compact footprint. Verify that the 5 A current rating meets the electrical load requirements of the connected circuitry. Consider the thermal operating range if the deployment environment experiences extreme temperatures. Ensure the solder pin termination method matches the assembly process capabilities.
