Here is an image showing the pin diagram of this transistor.The complementary NPN transistor to the BD190 is the BD189.The NZT660 (SOT-223) is the SMD version of the BD190 transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the BD190 with the 2N6035, 2N6035G, 2N6036, 2N6036G, 2SB1168, 2SB1168-Q, 2SB1168-R, 2SB1168-S, 2SB1168-T, BD440, BD440G, BD442, BD442G, BD678, BD678A, BD678AG, BD678G, BD680, BD680A, BD680AG, BD680G, BD682, BD682G, BD778, BD780, BD788, BD788G, BD790, BD792, KSE700, KSE701, KSE702, KSE703, MJE233, MJE234, MJE250, MJE251, MJE253, MJE253G, MJE700, MJE700G, MJE701, MJE701G, MJE702, MJE702G, MJE703 or MJE703G.
