Here is an image showing the pin diagram of this transistor.The 2SC4210 transistor can have a current gain of 100 to 320. The gain of the 2SC4210-O will be in the range from 100 to 200, for the 2SC4210-Y it will be in the range from 160 to 320.Sometimes the "2S" prefix is not marked on the package - the 2SC4210 might only be marked "C4210".The complementary PNP transistor to the 2SC4210 is the 2SA1621.You can replace the 2SC4210 with the BCW65, BCW66, FMMT619 or KTC3265.
