The KTC3198 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 KTC3198 transistor can have a current gain of 70 to 700. The gain of the KTC3198BL will be in the range from 300 to 700, for the KTC3198GR it will be in the range from 200 to 400, for the KTC3198O it will be in the range from 70 to 140, for the KTC3198Y it will be in the range from 120 to 240.The complementary PNP transistor to the KTC3198 is the KTA1266.The 2SC2712 (SOT-23), 2SC4116 (SOT-323), 2SC4738 (SOT-23), FJX945 (SOT-323), KTC3875 (SOT-23) and KTC3875S (SOT-23) is the SMD version of the KTC3198 transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.The 2SC3198 is the TO-92 version of the KTC3198.You can replace the KTC3198 with the 2SC1815, 2SC2458, 2SC3198, 2SC3199, 2SC3916, 2SC3917, 2SC3918, 2SC3919, 2SC3920, 2SC3921, 2SC3922, 2SC3923, C1815, C945, KSC1815, KSC945C or KTC3199.
