Edgeboard Connectors Procurement Notes

Verify the specific part number against official EDAC documentation to confirm compatibility with target PCB stack-up dimensions. Ensure that the required 1.57 mm board thickness aligns with manufacturing tolerances. Confirm that the vertical panel mount style matches the enclosure design constraints. Check RoHS compliance status if environmental regulations apply to the final assembly. Validate contact plating requirements against operational environment conditions.

Edgeboard Connectors Selection Notes

Select this component when a dual-row card edge interface with a 3.96 mm pitch is required for panel-mounted applications. Consider the 5 A current rating and -40 C to +105 C temperature range for suitability in industrial or automotive environments. Evaluate the vertical mounting orientation against available space constraints within the chassis. Compare alternative series such as 315 or 355 if different heights or contact configurations are needed.
