Here is an image showing the pin diagram of this transistor.The 2SD1568-L transistor can have a current gain of 80 to 120. The gain of the 2SD1568 will be in the range from 40 to 200, for the 2SD1568-K it will be in the range from 100 to 200, for the 2SD1568-M it will be in the range from 40 to 80.Sometimes the "2S" prefix is not marked on the package - the 2SD1568-L might only be marked "D1568-L".The complementary PNP transistor to the 2SD1568-L is the 2SB1090-L.You can replace the 2SD1568-L with the 2N5293, 2N5294, 2N6292, 2N6292G, 2N6293, 2N6473, 2N6474, 2N6487, 2N6487G, 2N6488, 2N6488G, 2SC1826, 2SC1827, 2SC1985, 2SC1986, 2SC2075, 2SC2233, 2SC2334, 2SC2334L, 2SC2527, 2SC3179, 2SC3253, 2SC3253-Q, 2SC3254, 2SC3254-Q, 2SC3255, 2SC3255-Q, 2SC3258, 2SC3258-O, 2SC3308, 2SC3308-O, 2SC3346, 2SC3346-O, 2SC3540, 2SC3540-O, 2SC3710, 2SC3710-O, 2SC3710A, 2SC3710A-O, 2SC3746, 2SC3746-Q, 2SC3747, 2SC3747-Q, 2SC3748, 2SC3748-Q, 2SC3834, 2SC3851, 2SC3851A, 2SC4153, 2SC4511, 2SC4511-P, 2SC4512, 2SC4512-P, 2SC789, 2SC789-O, 2SD1134, 2SD1134-B, 2SD1265, 2SD1265-O, 2SD1265A, 2SD1265A-O, 2SD1267, 2SD1267-Q, 2SD1267A, 2SD1267A-Q, 2SD1269, 2SD1269-R, 2SD1270, 2SD1270-R, 2SD1271, 2SD1271-R, 2SD1274, 2SD1274A, 2SD1274B, 2SD1355, 2SD1355-O, 2SD1356, 2SD1356-O, 2SD1362, 2SD1362-O, 2SD1407, 2SD1407-O, 2SD1407A, 2SD1407A-O, 2SD1408, 2SD1408-O, 2SD1411, 2SD1411-O, 2SD1411A, 2SD1411A-O, 2SD1588, 2SD1588-L, 2SD2059, 2SD2059-O, 2SD2060, 2SD2060-O, 2SD362, 2SD362-O, 2SD363, 2SD363-O, 2SD389, 2SD389-O, 2SD389A, 2SD389A-O, 2SD476A, 2SD476A-B, 2SD525, 2SD525-O, 2SD526, 2SD526-O, 2SD568, 2SD568-L, 2SD569, 2SD569-L, 2SD613, 2SD613-D, 2SD743, 2SD743-R, 2SD743A, 2SD743A-R, 2SD812, 2SD812-Q, 2SD823, 2SD857, 2SD857-Q, 2SD857A, 2SD857A-Q, 2SD866, 2SD866-R, 2SD866A, 2SD866A-R, BD203, BD243A, BD243B, BD243C, BD303, BD535, BD537, BD539A, BD539B, BD539C, BD539D, BD543A, BD543B, BD543C, BD545A, BD545B, BD545C, BD707, BD709, BD711, BD743A, BD743B, BD743C, BD797, BD799, BD801, BD807, BD809, BD907, BD909, BD911, BD949, BD951, BD953, BD955, BDT81, BDT81F, BDT83, BDT83F, BDT85, BDT85F, BDT87, BDT87F, BDT91, BDT91F, BDT93, BDT93F, BDT95, BDT95F, BDX77, D44H11, D44H11FP, D44H8, KSC2334, KSC2334O, KSD1408, KSD1408-O, KSD1588, KSD1588-O, KSD362, KSD362-O, KSD363, KSD363-O, KSD526, KSD526-O, KSD568, KSD568-O, KSD569, KSD569-O, KTC1003, KTC2018, KTC2018-O, KTC2027, KTC2027-O, KTC2028, KTC2028O, KTD2059, KTD2059O, KTD2060, KTD2060O, MJE15028, MJE15028G, NTE152, NTE196, TIP41D or TIP42D.
