| Market Reality | This is the chip-amp family of computer speakers, guitar practice amps and a hundred thousand DIY boards: five pins, tab at the negative rail, and a pinout so standard that TDA2030A, TDA2040, TDA2050 and LM1875 boards are routinely published as one PCB. The differences live in three numbers - supply ceiling, output power and peak current - and in one market reality: the TDA2050 is discontinued at ST and the open market is full of parts that are visibly TDA2030 dies under a 2050 laser. Substitution here is easy and the fake screening is mandatory; the 4-ohm corner is where an otherwise correct swap trips protection and sounds broken. | This is the chip-amp family of computer speakers, guitar practice amps and a hundred thousand DIY boards: five pins, tab at the negative rail, and a pinout so standard that TDA2030A, TDA2040, TDA2050 and LM1875 boards are routinely published as one PCB.
