Product details

Package and footprint

Housed in an 8-µMAX package (3.00mm width, MSOP-8 footprint), the MAX817LCUA is a surface-mount part suited for compact PCBs. The 8-µMAX shares the same 0.65mm pin pitch as a standard MSOP-8, so layout is straightforward. No heatsinking needed — the supervisor draws negligible current in normal operation.

RoHS status — a sourcing flag

This part is listed as RoHS non-compliant. If your assembly line or contract manufacturer requires lead-free / RoHS-compliant materials, the MAX817LCUA will not pass incoming inspection. For legacy builds or military/aerospace programs that still accept tin-lead finishes, it remains a valid choice. Confirm with your compliance team before committing the BOM.

Frequently asked questions

Is MAX817LCUA RoHS compliant?

No, the MAX817LCUA is RoHS non-compliant. It uses tin-lead solder finish and is not suitable for lead-free assembly processes.

What is the closest pin-compatible alternative to MAX817LCUA?

The MAX817LCUA is a specific threshold variant in the MAX817 family. A pin-compatible sibling with a different threshold (e.g., 4.65V vs 4.40V) may exist within the same family, but the evidence does not list a direct equivalent. For a drop-in replacement, verify the threshold and package against the datasheet family table.
