The 2SC828 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 2SC828 transistor can have a current gain of 130 to 520. The gain of the 2SC828-Q will be in the range from 130 to 260, for the 2SC828-R it will be in the range from 180 to 360, for the 2SC828-S it will be in the range from 260 to 520.Sometimes the "2S" prefix is not marked on the package - the 2SC828 might only be marked "C828".The complementary PNP transistor to the 2SC828 is the 2SA564.The MMBTH10 (SOT-23) is the SMD version of the 2SC828 transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the 2SC828 with the 2N3394, 2N3708, 2SC1815, 2SC2458, 2SC2785, 2SC2960, 2SC3114, 2SC3198, 2SC3199, 2SC3330, 2SC3331, 2SC3382, 2SC3383, 2SC3916, 2SC3917, 2SC3918, 2SC3919, 2SC3920, 2SC3921, 2SC3922, 2SC3923, 2SC536, 2SC828A, 2SC828A-Q, 2SC828A-R, 2SC828A-S, 2SC945, 2SD1207, 2SD1347, 2SD1835, 2SD545, 2SD789, BC167, BC182LB, BC184L, C1815, C945, H945, KSC1815, KSC945C, KTC3198 or KTC3199.
