Here is an image showing the pin diagram of this transistor.The 2SD568-K transistor can have a current gain of 100 to 200. The gain of the 2SD568 will be in the range from 40 to 200, for the 2SD568-L it will be in the range from 60 to 120, for the 2SD568-M it will be in the range from 40 to 80.Sometimes the "2S" prefix is not marked on the package - the 2SD568-K might only be marked "D568-K".The complementary PNP transistor to the 2SD568-K is the 2SB707-Y.You can replace the 2SD568-K with the 2SC2334, 2SC2527, 2SC3254, 2SC3254-R, 2SC3255, 2SC3255-R, 2SC3346, 2SC3710, 2SC3710A, 2SC3747, 2SC3747-R, 2SC3748, 2SC3748-R, 2SC3834, 2SC4153, 2SC4550, 2SC4550-M, 2SC4551, 2SC4551-M, 2SC4552, 2SC4552-M, 2SD1271, 2SD1362, 2SD1411, 2SD1411A, 2SD1588, 2SD1588-K, 2SD569, 2SD569-K, 2SD866, 2SD866A, BD203, BD303, BD535, BD537, BD543A, BD543B, BD543C, BD545A, BD545B, BD545C, BD797, BD799, BD801, BD807, BD809, BDT81, BDT81F, BDT83, BDT83F, BDT85, BDT85F, BDT87, BDT87F, BDT91, BDT91F, BDT93, BDT93F, BDT95, BDT95F, BDX77, D44H11, D44H11FP, D44H8, KSC2334, KSD1588, KSD1588-Y, KSD568, KSD568-Y, KSD569, KSD569-Y, MJE15028 or MJE15028G.
