The equivalent or alternate of BC550 are BC547, BC548, BC549, C945, 2S5200, C828, 2N2222 and many other. The pin configuration of the alternate transistors may different so, please must check the technical specification and pinout before using any alternate BC550 transistor.
BC550 is a general purpose an NPN transistor, in NPN transistor electrons work as the primary charge carriers that flow from the emitter of the transistor. When a positive voltage is applied to the base of the transistor the holes are created to the base of the transistor.
The complement transistor of BC550 Transistors is BC556, BC557, and BC558.
SMD Equivalent of the BC550 are available as the BC847 (SOT-23), BC847W(SOT-323), BC850 (SOT-23).
The 2D model and dimensions of BC550 are given below in the diagram
