Product details

No derating worry for ambient heat near motor drives or power supplies — the industrial temperature grade covers the typical factory floor.

Housed in a 16-SSOP (0.209", 5.30 mm width) surface-mount package. Supplier device package is 16-SSOP; footprint matches standard SSOP-16 land pattern.

Compliance and lifecycle

ROHS3 compliant, so no substance-restriction paperwork for EU-bound equipment. The + suffix in the order code indicates lead-free / RoHS-compliant finish; the base MAX221ECAE (without +) is the tin-lead version still found in some old BOMs.

Frequently asked questions

Is MAX221ECAE+ RoHS compliant and lead-free?

Yes, it is ROHS3 compliant. The + suffix in the order code denotes the lead-free / RoHS-compliant finish.

Can I order MAX221ECAE+ in tube packaging for prototyping?

The listing shows Tube packaging. Tube is standard for small quantities and prototyping — no need to buy a full reel for a handful of boards.

What is the difference between MAX221ECAE+ and MAX221ECAE?

The + suffix indicates lead-free / RoHS-compliant finish. The MAX221ECAE (without +) is the tin-lead version. Electrically identical; the choice is a RoHS compliance decision for your BOM.
