What 2T is
MMBT4403
- pnp bjt (SOT23 · on 7 of the parts below)
One code, more than one part. SMD marking codes are short, and manufacturers reuse them: the same code can be a different part in a different package
(a SOT-23 transistor and a SOD-123 diode can both be marked 2T), or from a different maker. Check the package and what the part does in the circuit before replacing it.
