Specs side by side
2 parts compared · 22 differing specs across 22 total parameters.
| Parameter | ||
|---|---|---|
| Operating temperature | - | -40°C ~ 110°C (TJ) |
| Supply voltage | VDRM/VRRM 600V; IT(RMS) 0.8A; ITSM 8A class; low hold current suited to dimmer and timer circuits. | - |
| Voltage - Gate Trigger (vgt) | - | 800 mV |
| Voltage - Off State | - | 600 V |
| Voltage - On State (vtm) | - | 1.5 V |
| Memory & Peripherals | BT169D (400V) and BT169G (600V) grades - the letter is the voltage, and the G matches the MCR100-8 class. | - |
| Case | TO-92 | TO-236-3, SC-59, SOT-23-3 |
| Package | - | Tape & Reel (TR) Cut Tape (CT) |
| Compatibility Level | Functional Equivalent | - |
| Core & Architecture | 0.8A / 600V sensitive-gate SCR in TO-92: the most-cited drop-in for the MCR100-8, with a comparable microamp-class gate trigger. | - |
| Current - Gate Trigger (igt) | - | 50 µA |
| Current - Hold (ih) | - | 5 mA |
| Current - Non Rep. Surge 50, 60Hz | - | 9A @ 60Hz |
| Current - Off State | - | 10 µA |
| Current - On State (it (rms)) | - | 250 mA |
| Firmware Notes | Verify the gate trigger current on the specific vendor datasheet against the MCR100-8 figure (IGT under 200uA): the circuit is usually an RC trigger with little margin, and a heavier-gate part simply stays off. | - |
| Hardware Notes | TO-92, but the lead arrangement must be read from the actual drawing: sources disagree on which of the three leads is gate and which is anode across MCR100 and BT169 documentation. Identify leads with a multimeter before committing a batch. | - |
| Lead Time Advantage | Shenzhen Spot Stock (24-48h Dispatch) | - |
| Mounting | - | Surface Mount |
| Reference Part | MCR100-8 | - |
| Scr Type | - | Sensitive Gate |
| Sourcing Advantage | Continuous multi-fab stock; the part actually used in production dimmers today. | - |
