Alternative Part Number

  • LM1875T --: Audio power amplifier IC in TO-220 package with comparable output power and supply range, widely available and often used as a substitute in audio circuits.
  • TDA2030A --: Class AB audio amplifier IC with similar power rating and pinout style, commonly used as a drop-in replacement in many Philips audio designs.
  • TDA2050 --: Higher-power audio amplifier IC in the same TDA family lineage with compatible supply voltage and package, suitable when slightly more output power is acceptable.
  • LM1036N --: Dual DC-operated tone/volume control IC with similar audio processing function and widely available as a replacement in audio control circuits.
  • TDA1524A --: Stereo tone and volume control IC from the same TDA audio family, functionally comparable and often used in similar audio applications.
  • LM1036M --: Surface-mount variant of the LM1036 tone/volume controller offering equivalent audio control functionality for compact designs.
