| Market Reality | The 2SC945 / 2SA733 pair is the Japanese-standard small-signal transistor of a generation of industrial controls, audio equipment and instruments - and it remains a daily repair item in Chinese production too, where the shorthand names C945 and A733 are stencilled on half the boards. Supply is continuous through second-source fabs, but three naming systems collide on this part: the C945 shorthand, the rank letters (O / Y / GR / BL), and the Japanese E-C-B pin order that is the mirror of the European C-B-E parts people try to substitute. | The 2SC945 / 2SA733 pair is the Japanese-standard small-signal transistor of a generation of industrial controls, audio equipment and instruments - and it remains a daily repair item in Chinese production too, where the shorthand names C945 and A733 are stencilled on half the boards.
