The 2SC1815Y 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 2SC1815Y transistor can have a current gain of 120 to 240. The gain of the 2SC1815 will be in the range from 70 to 700, for the 2SC1815GR it will be in the range from 200 to 400, for the 2SC1815L it will be in the range from 350 to 700, for the 2SC1815O it will be in the range from 70 to 140.Sometimes the "2S" prefix is not marked on the package - the 2SC1815Y might only be marked "C1815Y".The complementary PNP transistor to the 2SC1815Y is the 2SA1015Y.The 2SC1623 (SOT-23), 2SC2412 (SOT-23), 2SC2412-Q (SOT-23), 2SC2712 (SOT-23), 2SC2712-Y (SOT-23), 2SC4116 (SOT-323), 2SC4116-Y (SOT-323), 2SC4738 (SOT-23), 2SC4738-Y (SOT-23), FJX945 (SOT-323), FJX945Y (SOT-323), KSC1623 (SOT-23), KTC3875 (SOT-23), KTC3875S (SOT-23), KTC3875S-Y (SOT-23), KTC3875Y (SOT-23), MMBT2484 (SOT-23) and TMBT3904 (SOT-23) is the SMD version of the 2SC1815Y transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.The KSC1815Y is the TO-92 version of the 2SC1815Y.You can replace the 2SC1815Y with the 2SC1318, 2SC1318-R, 2SC1384, 2SC1384-R, 2SC1627, 2SC1627-Y, 2SC1627A, 2SC1627A-Y, 2SC2002, 2SC2003, 2SC2274, 2SC2274K, 2SC2277, 2SC2458, 2SC2458-Y, 2SC2655, 2SC2655Y, 2SC2960, 2SC3114, 2SC3198, 2SC3198-Y, 2SC3199, 2SC3199-Y, 2SC3243, 2SC3244, 2SC3328, 2SC3328-Y, 2SC3330, 2SC3331, 2SC3382, 2SC3383, 2SC3708, 2SC3916, 2SC3917, 2SC3918, 2SC3919, 2SC3920, 2SC3921, 2SC3922, 2SC3923, 2SC3940A, 2SC3940A-R, 2SC4208A, 2SC4208A-R, 2SC4408, 2SD1207, 2SD1347, 2SD1835, 2SD438, 2SD667, 2SD789, 2SD863, C1815, C1815Y, C945, C945Y, H945, KSC1008C, KSC1008CY, KSC1815, KSC1815Y, KSC2331, KSC2331Y, KSC945C, KSC945CY, KSP8098C, KSP8099C, KTC1006, KTC1008, KTC3198, KTC3198Y, KTC3199, KTC3199Y, KTC3209, KTC3209Y, KTC3227, KTC3227Y or KTD863.
