Here is an image showing the pin diagram of this transistor.The 2SC3228-O transistor can have a current gain of 100 to 200. The gain of the 2SC3228 will be in the range from 60 to 320, for the 2SC3228-R it will be in the range from 60 to 120, for the 2SC3228-Y it will be in the range from 160 to 320.Sometimes the "2S" prefix is not marked on the package - the 2SC3228-O might only be marked "C3228-O".The 2N5551S (SOT-23), DXT5551 (SOT-89), DZT5551 (SOT-223), KST43 (SOT-23), KST5551 (SOT-23) and MMBT5551 (SOT-23) is the SMD version of the 2SC3228-O transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.The KTC3228O is the TO-92 version of the 2SC3228-O.You can replace the 2SC3228-O with the 2SC2383, 2SC2383O, KSC2383, KSC2383O, KTC3228 or KTC3228O.
