Here is an image showing the pin diagram of this transistor.The 2SD1892-Q transistor can have a current gain of 8000 to 30000. The gain of the 2SD1892 will be in the range from 5000 to 30000, for the 2SD1892-P it will be in the range from 5000 to 15000.Sometimes the "2S" prefix is not marked on the package - the 2SD1892-Q might only be marked "D1892-Q".The complementary PNP transistor to the 2SD1892-Q is the 2SB1252-Q.You can replace the 2SD1892-Q with the 2SD1195, 2SD1196, 2SD1829, 2SD1830, 2SD2495, 2SD772, 2SD772A, 2SD792, 2SD792A, BD243C, BD539C, BD539D, BD543C, BD545C, BD649, BD651, BD801, BD901, BD953, BD955, BDT63B, BDT63C, BDT65B, BDT65C, BDT85, BDT85F, BDT87, BDT87F, BDW42, BDW42G, BDW43, BDX33C, BDX33CG, BDX33D, BDX53C, BDX53CG, BDX53D, BDX53E, BDX53F, MJE15028, MJE15028G, MJE15030, MJE15030G, MJF122, MJF122G, MJF15030, MJF15030G, TIP122, TIP122G, TIP142T, TIP41D, TIP41E, TIP41F, TIP42D, TIP42E or TIP42F.
