The MPS6531 is manufactured in a plastic TO-92 case. When looking at the flat side with the leads pointed downward, the three leads emerging from the transistor are, from left to right, the emitter, base, and collector leads.
Here is an image showing the pin diagram of this transistor.The complementary PNP transistor to the MPS6531 is the MPS6534.The 2SD602A (SOT-23) is the SMD version of the MPS6531 transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the MPS6531 with the 2SC1008, BC537, BC538, KSC1008, MPS650, MPS650G, MPS651, MPS651G, MPSW01A or MPSW01AG.
