The 2N5815 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 2N5815 is the 2N5814.The 2SA1518 (SOT-23), 2SA1519 (SOT-23), 2SA1520 (SOT-23) and 2SA1521 (SOT-23) is the SMD version of the 2N5815 transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the 2N5815 with the 2N5821, BC486, BC486L, BC488, BC488L, BC490 or BC490L.
