Substitute Part Grouping Explanation

Substitution of the AH373-SAC-7 is determined by strict alignment of the following electrical and mechanical parameters:

  • Package Compatibility: Both parts must use SOT-23-3 surface mount packaging to ensure PCB footprint compatibility
  • Functional Equivalence: Both parts must operate as latching Hall Effect magnetic switches with open drain output
  • Sensing Characteristics: Identical sensing range (6mT trip, -6mT release) and South Pole polarization
  • Output Configuration: Open drain output type with matching electrical characteristics
  • Temperature Compensation: Both parts include temperature compensation feature
  • Operating Temperature Range: Full overlap within -40°C ~ 125°C specification
  • Compliance Standards: RoHS3 compliance and REACH unaffected status maintained

The AH3782-SA-7 meets all substitution criteria as an active product from the same manufacturer with identical functional specifications and package form factor.
