Specs side by side
2 parts compared · 13 differing specs across 14 total parameters.
| Parameter | ||
|---|---|---|
| Supply voltage | - | VCBO 230V; IC 15A; IB 1.5A; TJ 150 degC max; fT 30MHz class. |
| Memory & Peripherals | - | Complementary PNP is the TTA1943 - order the pair from one lot for gain matching. |
| Compatibility Level | - | 100% Drop-in (Zero Code Change) |
| Component Category | Audio Power Transistors (Complementary Pair) | - |
| Core & Architecture | - | Same die family and ratings as the 2SC5200: 230V VCEO, 15A, 150W at TC=25 degC, VCE(sat) 3V max at 8A. Delivered as a single hFE rank (80-160) with lower output capacitance (240pF versus 360pF) for better complementary matching. |
| Firmware Notes | - | The cleanest way to avoid counterfeit 2SC5200/2SA1943: order the TTC/TTA continuation numbers, which are in active Toshiba production and far less attractive to relabelers. |
| Hardware Notes | - | Same TO-3P(L) outline and 1-B / 2-C / 3-E pin order as the original pair; existing heatsink hardware and insulator kits fit unchanged. |
| 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 | - | Active factory production; verified-lot supply with photographed markings before dispatch. |
| Sourcing Status | Active Shenzhen Spot Sourcing (24–48h) | - |
