| Parameter | ||
|---|---|---|
| Supply voltage | - | VCEO 250V; VCBO 250V; RthJC 0.83 degC/W; TJ -65 to +150 degC. |
| Memory & Peripherals | - | Complementary PNP is the NJW0302G. NPN/PNP gain matching within 10 percent from 50mA to 3A. |
| Case | TO-3P(L) | TO-3P |
| Compatibility Level | - | Functional Equivalent |
| Component Category | Audio Power Transistors (Complementary Pair) | - |
| Core & Architecture | - | NPN of the onsemi audio pair: 250V VCEO, 15A (30A peak), 150W, hFE 75-150, fT about 30MHz - the closest electrical match to the 2SC5200 among the second sources. |
| Firmware Notes | - | Higher voltage for margin at the same speed. Re-check the class-AB bias current after substitution: the hFE window (75-150) differs from the original part (55-160), and bias drifts with gain class. |
| Hardware Notes | - | TO-3P outline, same mounting class; verify the pin order against the board silkscreen as with any cross-family swap. |
| 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 | - | Pb-free active production line; a mainstream Western-branded option for customers whose documentation requires it. |
| Sourcing Status | Active Shenzhen Spot Sourcing (24–48h) | - |
