Substitute Part Grouping Explanation

Substitution of the MAX4080SASA is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part must maintain identical specifications in the following categories:

Electrical Parameters: Amplifier type (Current Sense), number of circuits (1), bandwidth (250 kHz), input bias current (5 µA), input offset voltage (100 µV), supply current (75 µA), and supply voltage range (4.5 V to 76 V).

Thermal Parameters: Operating temperature range (-40°C to 125°C) must be maintained.

Mechanical Parameters: Package type (8-SOIC with 0.154" width, 3.90mm) and surface mount mounting type are mandatory for physical compatibility.

Compliance Parameters: RoHS3 compliance and MSL rating (1) must be preserved.

The MAX4080SASA+ qualifies as a direct substitute based on complete parameter equivalence across all specified categories.

Parameter Comparison

Engineering Selection Recommendations

The MAX4080SASA+ is a direct functional and physical equivalent to the MAX4080SASA. Both parts share identical electrical specifications, thermal operating range, and mechanical packaging. The primary distinction is product status: the MAX4080SASA is obsolete, while the MAX4080SASA+ maintains active production status.

For new designs or production continuity, the MAX4080SASA+ is the appropriate selection. Both parts maintain ROHS3 compliance and identical MSL ratings, ensuring regulatory and environmental compatibility. The active production status of the MAX4080SASA+ provides supply chain stability and long-term availability assurance.

Existing designs utilizing the MAX4080SASA can transition to the MAX4080SASA+ without circuit modification, as all electrical and mechanical parameters are identical. No design re-qualification is required for this substitution.
