The 2N5819 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 2N5819 is the 2N5818.The 2SA1366 (SOT-23), 2SA1366-E (SOT-23), 2SA1518 (SOT-23), 2SA1519 (SOT-23), 2SA1520 (SOT-23), 2SA1521 (SOT-23), 2SB710A (SOT-23), BC807 (SOT-23), BC807W (SOT-323), BCX17 (SOT-23), FMMT2907 (SOT-23), FMMT2907R (SOT-23), KN2907S (SOT-23), KTN2907S (SOT-23), KTN2907U (SOT-323), PMBT2907 (SOT-23) and PMST2907 (SOT-23) is the SMD version of the 2N5819 transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the 2N5819 with the BC327, BC486, BC488 or BC490.
