Alternative Part Number

  • HT9312 --: Same Holtek HT93 series base device without the B revision suffix; functionally equivalent for most applications and widely available.
  • HT93C46 --: Holtek 93-series serial EEPROM with comparable interface and memory organization; suitable drop-in for many HT9312B use cases.
  • AT93C46 --: Industry-standard 93C46-compatible serial EEPROM from a different vendor, offering similar pinout and protocol as a cross-manufacturer alternative.
  • PT9312B --: Pin-compatible IR remote control encoder IC with the same 9312B function and similar electrical characteristics.
  • SC9312B --: Direct functional equivalent remote control encoder IC commonly used as a drop-in replacement for the 9312B series.
  • TC9312B --: Alternative remote control encoder IC offering comparable encoding functions and supply voltage range.
