Nexperia USA Inc.
Needs validationhigh risk
BC846A may fit low-current NPN SOT-23 roles but is not a full PMBT2222A replacement.
Best Alternatives to PMBT2222A,215
PMBT2222A,215 is an active NPN SOT-23 transistor. The listed alternates need review because pinout is not verified and ratings differ.
AI replacement insight
Electrical riskhigh
BC846A/BC847A are 100mA parts
Package riskmedium
SOT-23 matches but pinout is missing
Firmware risklow
discrete BJT, no firmware
Sourcing risklow
kept candidates are active
Can it be replaced directly?
No confirmed pin-compatible replacement is proven from these candidates.
Best replacement path
Use an NPN SOT-23 with verified pinout and at least 40V, 600mA, 300MHz ratings.
Main risk
Lower current and transition frequency on kept candidates.
