AI replacement insight
Electrical riskmedium
Vin, FB, OVP and current limits must match.
Package risklow
Kept parts are SOT23-6.
Firmware risklow
PWM dimming behavior may still differ.
Sourcing riskmedium
Lifecycle evidence is mixed.
Can it be replaced directly?
No direct pin-compatible MT9201 replacement is confirmed.
Best replacement path
Start with SY7201ABC, then verify pinout and external parts.
Main risk
Pinout and input voltage limits.
