Product details

Temperature grade and environment

Rated for 0°C to 70°C, this is a commercial-temperature part. It belongs in office equipment, appliances, and indoor PCBs — not in a motor drive enclosure or an engine bay. If the board sees an unheated warehouse or a rooftop telecom cabinet, look for an industrial-grade supervisor.

RoHS flag — lead-free assembly check

Marked RoHS non-compliant, the MAX808NCSA uses tin-lead solder finish. If your production line is restricted to lead-free alloys, this part needs a waiver or a RoHS-compliant alternative. For rework and repair of legacy boards, the tin-lead finish is actually preferred — it wets better on old solder pads.

Sourcing and lifecycle

No last-time-buy risk for current BOMs. For dual-source planning, Maxim's supervisor family includes pin-compatible options with different threshold voltages, but no official second-source alternate is listed for this exact code.

Frequently asked questions

What is the reset timeout of MAX808NCSA?

The reset timeout is a minimum of 140ms. After the monitored voltage rises above the 4.575V threshold, the reset output stays low for at least 140ms before releasing.

Is MAX808NCSA RoHS compliant?

No, it is listed as RoHS non-compliant. The part uses tin-lead solder finish, which may require a waiver for lead-free assembly lines.
