Specs side by side
2 parts compared · 13 differing specs across 14 total parameters.
| Parameter | ||
|---|---|---|
| Supply voltage | - | VCBO -230V; IC -15A; TJ 150 degC max. |
| Memory & Peripherals | - | Order with TTC5200 in matching quantities - class-AB output stages need the pair balanced. |
| Compatibility Level | - | 100% Drop-in (Zero Code Change) |
| Component Category | Audio Power Transistors (Complementary Pair) | - |
| Core & Architecture | - | The PNP member of the TTC5200/TTA1943 pair: -230V VCEO, -15A, 150W, single hFE rank 80-160. |
| Firmware Notes | - | Replaces the 2SA1943 position in every circuit this pair is known for. Replacing only the NPN half of an output stage with the new rank is possible but leaves the complementary balance to be re-verified. |
| Hardware Notes | - | TO-3P(L) outline, 1-B / 2-C / 3-E - identical mounting to the part it replaces. |
| Lead Time Advantage | - | Shenzhen Spot Stock (24-48h Dispatch) |
| Market Reality | The 2SC5200 (NPN) and 2SA1943 (PNP) pair is the default output stage of generations of audio amplifiers, and it is one of the most counterfeited transistor families in the world - relabeled and re-died parts circulate heavily through marketplaces. Genuine Toshiba supply continues under the TTC5200 / TTA1943 part numbers with identical ratings, and the ON Semiconductor (onsemi) NJW0281G / NJW0302G and MJL21194 / MJL21193 pairs are the established second sources. For repair desks the hard problem is not finding a part - it is finding one that is not a relabel. | - |
| Reference Part | - | 2SC5200 / 2SA1943 |
| Role In Circuit | Original Reference Part | - |
| Sourcing Advantage | - | Same lot-sourcing discipline as the TTC5200: one production lot, photographed before dispatch. |
| Sourcing Status | Active Shenzhen Spot Sourcing (24–48h) | - |
| Case | TO-3P(L) | TO-3P(L) |
