Alternative Part Number

  • S-80840CLMC-B6FT2G --: ABLIC (formerly Seiko Instruments) S-808xx voltage detector series offers similar reset/detection functionality and is a direct functional replacement for the S-8438AF supervisory IC.
  • S-80945CLMC-G6FT2G --: ABLIC S-809xx series voltage detector with comparable detection voltage and output configuration, suitable as a drop-in alternative for the Seiko S-8438AF.
  • MAX809REUR+T --: Industry-standard 3-pin microprocessor reset supervisor with similar reset threshold and active-low output, widely used as a cross-manufacturer alternative to Seiko S-84xx detectors.
