The KSC1815Y 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 KSC1815Y transistor can have a current gain of 120 to 240. The gain of the KSC1815 will be in the range from 70 to 700, for the KSC1815GR it will be in the range from 200 to 400, for the KSC1815L it will be in the range from 350 to 700, for the KSC1815O it will be in the range from 70 to 140.The complementary PNP transistor to the KSC1815Y is the KSA1015Y.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 KSC1815Y transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.The 2SC1815Y is the TO-92 version of the KSC1815Y.You can replace the KSC1815Y with the 2SC1318, 2SC1318-R, 2SC1384, 2SC1384-R, 2SC1627, 2SC1627-Y, 2SC1627A, 2SC1627A-Y, 2SC1815, 2SC1815Y, 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, KSC2331, KSC2331Y, KSC945C, KSC945CY, KSP8098C, KSP8099C, KTC1006, KTC1008, KTC3198, KTC3198Y, KTC3199, KTC3199Y, KTC3209, KTC3209Y, KTC3227, KTC3227Y or KTD863.
