Alternative Part Number

  • TDA8425 --: NXP (formerly Philips) audio processor in the same TDA series with similar I2C-controlled audio switching and processing functions, often used as a substitute in audio systems.
  • TDA7439 --: I2C-bus controlled audio processor with volume, tone, and input selection features comparable to the TDA9855, widely available from ST.
  • PT2313L --: Low-cost I2C audio processor offering input selection, volume, and tone control, functionally similar and commonly used as a replacement in consumer audio designs.
  • TDA9855 --: Base version of the same audio processor IC from the successor brand of Philips; functionally equivalent with the same core features, drop-in for most designs.
  • TDA9850 --: Closely related Philips/NXP TV audio processor in the same family with similar I2C control and audio processing functions; usable with minor pin/configuration checks.
