Here is an image showing the pin diagram of this transistor.The complementary NPN transistor to the BD227 is the BD226.The BCP51 (SOT-223) is the SMD version of the BD227 transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the BD227 with the BD132, BD136, BD136G, BD138, BD138G, BD140, BD140G, BD166, BD168, BD170, BD176, BD178, BD180, BD180G, BD188, BD190, BD229, BD231, BD234, BD234G, BD236, BD236G, BD238, BD238G, BD376, BD378, BD380, BD786, BD788, BD788G, BD790, MJE235, MJE252, MJE711 or MJE712.
