The 2N3392 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 emitter, collector, and base leads.
Here is an image showing the pin diagram of this transistor.The BC818 (SOT-23) and BC818W (SOT-323) is the SMD version of the 2N3392 transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the 2N3392 with the 2N3394, 2N3704, 2SC1317, 2SC1318, 2SC1383, 2SC1384, 2SC1959, 2SC2001, 2SC2120, 2SC2236, 2SC2274, 2SC2277, 2SC2328A, 2SC2500, 2SC2500-A, 2SC2500-B, 2SC2500-C, 2SC2500-D, 2SC2710, 2SC3203, 2SC3205, 2SC3916, 2SC3917, 2SC3918, 2SC3919, 2SC3920, 2SC3921, 2SC3922, 2SC3923, 2SC3940, 2SC3940A, 2SC4208, 2SC4208A, 2SC4408, 2SC4604, 2SD1207, 2SD1347, 2SD1616, 2SD1835, 2SD471, 2SD545, 2SD592, 2SD592A, 2SD789, 2SD863, KSC2328A, KSC2500, KSC2500-A, KSC2500-B, KSC2500-C, KSC2500-D, KSC5019, KSD1020, KSD1021, KSD1616, KSD471AC, KTC3203, KTC3204, KTC3205, KTC3210, KTC3211, KTD863 or PN3643.
