The BC448A 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 collector, base, and emitter leads.
Here is an image showing the pin diagram of this transistor.The complementary NPN transistor to the BC448A is the BC447A.The 2SA1620 (SOT-23) and 2SA1620-Y (SOT-23) is the SMD version of the BC448A transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the BC448A with the BC448, BC450, BC450A, BC490 or BC490A.
