Here is an image showing the pin diagram of this transistor.The complementary PNP transistor to the BD189 is the BD190.The 2STF1360 (SOT-89), 2STN1360 (SOT-223), FZT692B (SOT-223), NZT560 (SOT-223) and NZT560A (SOT-223) is the SMD version of the BD189 transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the BD189 with the 2N6038, 2N6038G, 2N6039, 2N6039G, 2SD1725, 2SD1725-Q, 2SD1725-R, 2SD1725-R, 2SD1725-S, BD439, BD439G, BD441, BD441G, BD677, BD677A, BD677AG, BD677G, BD679, BD679A, BD679AG, BD679G, BD681, BD681G, BD777, BD779, BD787, BD787G, BD789, BD791, BDX35, BDX36, BDX37, KSE800, KSE801, KSE802, KSE803, MJE223, MJE224, MJE240, MJE241, MJE243, MJE243G, MJE800, MJE800G, MJE801, MJE801G, MJE802, MJE802G, MJE803 or MJE803G.
