SS8050 is a 1.5A NPN SOT-23 transistor. Most listed NPN options are lower-current parts and need FAE review.

AI replacement insight

Electrical riskhigh

kept parts are 0.5A vs 1.5A

Package riskmedium

SOT-23 matches but pinout is missing

Firmware risklow

discrete BJT, no firmware

Sourcing risklow

Can it be replaced directly?

No pin-compatible replacement is proven from the provided evidence.

Best replacement path

Start with BC817-40 or MMBTA06 only for derated, low-current circuits.

Main risk

Collector current and unverified pinout.
