| Market Reality | The MCR100-8 is the small sensitive-gate SCR that made lamp dimmers, timers and simple phase controls cheap: 0.8A, 600V, a TO-92 body the size of a transistor, and a gate that triggers on a couple of hundred microamps straight from an RC network. The original onsemi line is end-of-life and the market is served by second sources - the classic cross being the BT169 family and the ST X00602MA. Two facts govern every substitution: the gate sensitivity class (a heavier-gate SCR simply will not trigger in these circuits) and the lead arrangement, on which vendor documentation is famously inconsistent. | - |
