Alternative Part Number

  • STK403-330 --: Same-class thick-film hybrid audio power amplifier with comparable output rating and pinout, widely used as a drop-in replacement for STK401 series modules.
  • STK404-330 --: Similar hybrid audio power IC in the STK40x family with matching supply voltage and output power class, suitable with minor heatsink and bias checks.
  • LM3886TF --: Discrete-chip alternative audio power amplifier offering comparable output power; requires circuit adaptation but is a reliable modern substitute when the hybrid module is unavailable.
  • TDA7294 --: Widely used Class-AB audio power amplifier IC with comparable output power and voltage ratings, commonly used as a substitute for Sanyo STK-series hybrid audio modules.
  • STK404-130 --: Sanyo STK-series audio power amplifier module with similar pinout and power class, serving as a functional replacement when the exact STK401-330 is unavailable.
