Here is an image showing the pin diagram of this transistor.The complementary NPN transistor to the BC160-6 is the BC140-6.The BCP51 (SOT-223) is the SMD version of the BC160-6 transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the BC160-6 with the 2N2102, 2N2102A, 2N4036, 2N4234, 2N4235, 2N4236, 2N4404, 2N4406, 2N5323, 2N5333, 2N6190, 2SA512, BC160, BC161, BC161-6, BC460 or BC461.
