Substitute Part Grouping Explanation

Substitution of the MAX604ESA is determined by strict equivalence across the following critical parameters:

  • Output configuration (Positive)
  • Output type (Adjustable/Fixed)
  • Number of regulators (1)
  • Maximum input voltage (11.5V)
  • Output voltage range (1.25V to 11V)
  • Maximum dropout voltage (0.82V @ 400mA)
  • Output current capability (500mA)
  • Quiescent current (35 µA)
  • Control features (Enable function)
  • Protection features (Over Current, Over Temperature, Reverse Polarity)
  • Operating temperature range (-40°C ~ 85°C)
  • Package type (8-SOIC)

The MAX604ESA+ is identified as a direct substitute based on identical electrical specifications and mechanical compatibility. The primary distinction is product status and compliance certification.

Engineering Selection Recommendations

The MAX604ESA+ is the direct functional equivalent of the MAX604ESA. Both devices share identical electrical and mechanical specifications, ensuring pin-for-pin compatibility and equivalent circuit performance.

The MAX604ESA+ is currently in active production status, whereas the MAX604ESA is obsolete. For new designs and ongoing production requirements, the MAX604ESA+ is the appropriate selection.

The MAX604ESA+ carries ROHS3 compliance certification, meeting current regulatory requirements for electronic components in restricted substance directives. The original MAX604ESA is RoHS non-compliant. This distinction is significant for applications subject to environmental and regulatory compliance mandates.

Both devices maintain identical moisture sensitivity levels (MSL 1 - Unlimited), indicating no special handling requirements during storage or assembly.
