    For my project, i need ztx313. But in my country, i didn't find it. As i am studying in mechanical engineering,i have a little knowledge in electric field. Can anyone inform me what are the equivalent transistor of ztx313?

    it depends on what kind of equivalency you are looking for: similar breakdown voltage? beta? packaging? number of pins? ...

    wouldn't that depend on your circuit?

    it's my hot wire anemometer circuit diagram. only transistor ztx313 could not be found, what are the alternatives of it?

    it depends on the (max) value of R11(2).

    but the circuit doesn't seem to utilize any special properties of the ztx313. so any small signal transistor, like 2222, 5551, etc., would work. I don't think darlington is required either.

    the 358 would be a much better substitute for the 741 here, especially since you are already using one.
