Substitute Part Grouping Explanation

Substitution of the MAX4236BESA is determined by strict equivalence across all electrical and mechanical parameters. The substitute part must maintain identical specifications for amplifier type, number of circuits, output configuration, slew rate, gain bandwidth product, input bias current, input offset voltage, supply current, output current capability, supply voltage range, operating temperature range, and physical package dimensions.

The MAX4236BESA+ qualifies as a direct substitute based on complete parameter alignment across all specified electrical characteristics and mechanical form factor. Both parts share the same base product number (MAX4236), identical 8-SOIC packaging, and equivalent performance specifications. The primary distinction between these parts is product status and packaging format.

Parameter Comparison

Engineering Selection Recommendations

The MAX4236BESA+ is the direct equivalent for the obsolete MAX4236BESA. Selection of the MAX4236BESA+ is appropriate for new designs and replacement procurement due to its active product status with Analog Devices Inc./Maxim Integrated. Both parts maintain ROHS3 compliance and identical electrical performance specifications across all measured parameters.

The MAX4236BESA+ is supplied in tube packaging format, whereas the original MAX4236BESA packaging format is not specified in the provided data. This packaging difference does not affect electrical or mechanical compatibility when used in surface mount assembly processes. Both parts are classified as MSL Level 1 (Unlimited), indicating no moisture sensitivity constraints during storage or handling.

For applications requiring the MAX4236BESA, direct substitution with MAX4236BESA+ is supported by complete parameter equivalence and active manufacturer support status.
