Substitute Part Grouping Explanation

Substitution eligibility for the MAX4528ESA is determined by strict equivalence across the following critical parameters:

  • Switch circuit configuration (SPDT)
  • Number of circuits (2)
  • Multiplexer/demultiplexer circuit topology (2:1)
  • On-state resistance specification (110Ohm maximum)
  • Channel-to-channel matching tolerance (3Ohm)
  • Supply voltage ranges (single and dual configurations)
  • Charge injection and leakage specifications
  • Package type and pin configuration (8-SOIC)
  • Operating temperature range (-40°C ~ 85°C)

The MAX4528ESA+ qualifies as a direct substitute based on identical electrical specifications and mechanical compatibility across all these parameters.

Engineering Selection Recommendations

The MAX4528ESA+ is the direct functional equivalent of the MAX4528ESA. Both parts maintain identical electrical and mechanical specifications across all critical switching parameters. The primary distinction lies in product lifecycle status and regulatory compliance.

The MAX4528ESA is classified as obsolete, whereas the MAX4528ESA+ maintains active product status with current manufacturing support. The MAX4528ESA+ additionally achieves ROHS3 compliance, compared to the non-compliant status of the original MAX4528ESA. This compliance improvement aligns with current environmental and regulatory requirements for electronic component procurement.

For new designs and ongoing production requiring this switch topology, the MAX4528ESA+ is the appropriate selection. For legacy system maintenance where the original MAX4528ESA is specified, the MAX4528ESA+ provides full electrical and mechanical compatibility without design modification.
