AI replacement insight

Electrical riskmedium

Capacitance and clamping voltage differences require analysis for the specific application.

Package risklow

The SOT23-6 package is a match, but pinout verification is critical.

Can it be replaced directly?

Direct replacement for TPNUP4201MR6T1G should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.

Best replacement path

TPD4E1U06DBVR offers a close functional match with upgraded power ratings, but requires pinout and capacitance checks.

Main risk

The primary risk is pinout incompatibility within the SOT23-6 package for 4-line TVS arrays.

Recommended alternatives

A 4-line TVS array in a SOT23-6 package with higher power rating. A strong candidate pending pinout verification.
