Likely pin-compatible 4-line TVS array with identical key electrical parameters including capacitance and voltage.
Best Alternatives to NUP4201MR6T1G
NUP4201MR6T1G is an obsolete 4-line, low-capacitance TVS array in a SOT23-6 package for high-speed data line protection. Alternatives with matching electrical and physical properties are available, with some likely being pin-compatible.
AI replacement insight
Package risklow
SOT23-6 package is standard and matches across promising candidates.
Electrical riskmedium
Pinout must be verified. Some alternatives have slightly different clamping voltages that need evaluation for the specific application.
Sourcing risklow
The target is obsolete, but several clone-like alternatives from Asian manufacturers appear to be available.
Can it be replaced directly?
Direct replacement for NUP4201MR6T1G should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
Best replacement path
Start with Datasheet verified or Strong match candidates for NUP4201MR6T1G, then review parametric alternatives for package and electrical fit.
Main risk
The primary risk is an incorrect pinout, which would prevent a drop-in replacement. Secondary risks include minor variations in clamping voltage or ESD performance.
