How to find out that it is MMBT5551? The silk screen reverse check website is not easy to use now, and there are many similar ones.

I'm not sure if it's MMBT5551, there are a lot of similar ones, and by the way I checked J3 (S9013), but it's a different model. So I'm not sure, that's why I asked this question.

There are still many models. It is best to analyze the circuit and judge based on the function to narrow down the possible model range.
