Here is an image showing the pin diagram of this transistor.The complementary PNP transistor to the BD226 is the BD227.The BCP54 (SOT-223) is the SMD version of the BD226 transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the BD226 with the BD131, BD135, BD135G, BD137, BD137G, BD139, BD139G, BD165, BD167, BD169, BD175, BD177, BD179, BD187, BD189, BD228, BD230, BD233, BD233G, BD235, BD235G, BD237, BD237G, BD375, BD377, BD379, BD785, BD787, BD787G, BD789, MJE225, MJE242, MJE721 or MJE722.
