| Supply voltage | Same class; per-lot behavior is the verification item. | - |
| Memory & Peripherals | One honest engineering note from the original datasheet: the TEA2025B carries internal output-to-ground resistors for lower pop and crossover artifacts - some clones leave that behavior to external parts. In pop-sensitive products, fit and verify rather than assume. | - |
| Case | DIP-16 | DIP-16 (PowerDIP) |
| Compatibility Level | Functional Equivalent | - |
| Component Category | - | Audio Power Amplifiers (Low Power Stereo) |
| Core & Architecture | The Chinese member of the TEA2025 application family (with the D2025 sibling): same pins and circuit role, the line that kept toy and speaker production alive after the ST part went NRND. | - |
| Firmware Notes | For repair and volume the clones are the practical supply; screen the first article for quiescent current and power-up pop, then standardize a lot. | - |
| Hardware Notes | DIP-16 standard. | - |

| Market Reality | - | The TEA2025B is the little stereo amplifier of a generation of speakers, radios, toys and monitors: 2x2.3W at 9V per channel, 16 pins, and a bridge mode for a single louder channel - now NRND at ST and kept alive by a well-behaved clone row (KA2206, CD2025GP, D2025) plus the same-family D-variant. The trap around this part is the Samsung KA2209: an 8-pin flea-power walkman chip whose name sits next to the TEA2025 in substitution tables and whose package, supply range and power class are all different - the kind of "equivalent" that fits nothing. And the quiet engineering detail: the TEA2025B carries internal output-to-ground resistors that tame power-up pops, which most clones reproduce only with external parts added. |
