The 2SD471M 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 2SD471M transistor can have a current gain of 90 to 180. The gain of the 2SD471 will be in the range from 90 to 400, for the 2SD471K it will be in the range from 200 to 400, for the 2SD471L it will be in the range from 135 to 270.Sometimes the "2S" prefix is not marked on the package - the 2SD471M might only be marked "D471M".The complementary PNP transistor to the 2SD471M is the 2SB564M.The 2SC2859 (SOT-23), 2SC4118 (SOT-323), 2SD874 (SOT-89), 2SD874-Q (SOT-89), KSC2859 (SOT-23), KTC3876 (SOT-23) and KTC3876S (SOT-23) is the SMD version of the 2SD471M transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the 2SD471M with the 2SC1383, 2SC1384, 2SC2655, 2SC3940, 2SC3940A, 2SD545, 2SD592, 2SD592A, 2SD863, KTC3209, KTC3211 or KTD863.
