Here is an image showing the pin diagram of this transistor.The 2SB601-K transistor can have a current gain of 5000 to 15000. The gain of the 2SB601 will be in the range from 2000 to 15000, for the 2SB601-L it will be in the range from 3000 to 7000, for the 2SB601-M it will be in the range from 2000 to 5000.Sometimes the "2S" prefix is not marked on the package - the 2SB601-K might only be marked "B601-K".The complementary NPN transistor to the 2SB601-K is the 2SD560-KB.You can replace the 2SB601-K with the 2N6042, 2N6042G, 2SB1020, 2SB1020A, 2SB1227, 2SB1228, 2SB1252, 2SB1252-P, 2SB1626, 2SB673, 2SB885, 2SB886, BD244C, BD540C, BD544C, BD546C, BD650, BD652, BD802, BD902, BD954, BD956, BDT62B, BDT62C, BDT64B, BDT64C, BDT86, BDT86F, BDT88, BDT88F, BDW24C, BDW47, BDW47G, BDW48, BDW64C, BDW64D, BDW74C, BDW74D, BDX34C, BDX34CG, BDX34D, BDX54C, BDX54CG, BDX54D, BDX54E, BDX54F, MJE15029, MJE15029G, MJE15031, MJE15031G, MJF127, MJF127G, MJF15031, MJF15031G, MJF6668, MJF6668G, TIP107, TIP107G, TIP127, TIP127G, TIP137, TIP137G, TIP147T or TTB1020B.
