Here is an image showing the pin diagram of this transistor.The complementary NPN transistor to the BC160 is the BC140.The BCP51 (SOT-223) is the SMD version of the BC160 transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the BC160 with the 2N5323, BC161, BC460 or BC461.
