Here is an image showing the pin diagram of this transistor.The 2SC2229-O transistor can have a current gain of 70 to 140. The gain of the 2SC2229 will be in the range from 70 to 240, for the 2SC2229-Y it will be in the range from 120 to 240.Sometimes the "2S" prefix is not marked on the package - the 2SC2229-O might only be marked "C2229-O".The KTC4372 (SOT-89) and KTC4372O (SOT-89) is the SMD version of the 2SC2229-O transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the 2SC2229-O with the 2SC1473, 2SC1473A, 2SC1473AQ, 2SC1473Q, 2SC1573, 2SC1573-Q, 2SC1573A, 2SC1573A-Q, 2SC2271, 2SC2383, 2SC2482, 2SC2551, 2SC2551-O, 2SC3206, 2SC3206-O, 2SC3228, 2SC3467, 2SC3468, 2SC3941, 2SC3941-Q, BF420, BF422, HSD1609S, KSC1506, KSC1506-O, KSC2310, KSC2310-O, KSC2330, KSC2330O, KSC2383, KTC3206, KTC3206O or KTC3228.
