Substitute Part Grouping Explanation

Substitution of the MAX890LESA is determined by strict equivalence across the following critical parameters:

• Output configuration (High Side P-Channel)
• Maximum output current (1.2A)
• Load voltage range (2.7V ~ 5.5V)
• On-state resistance (75mOhm typical)
• Control interface (On/Off, Non-Inverting)
• Protection features (Adjustable current limiting, over-temperature shutdown)
• Physical package (8-SOIC)
• Operating temperature range (-40°C ~ 85°C)

The MAX890LESA+ qualifies as a direct substitute based on identical electrical specifications and mechanical compatibility. The primary distinction between these parts is product status and compliance certification.

Parameter Comparison

Engineering Selection Recommendations

The MAX890LESA+ is the direct functional equivalent of the MAX890LESA. Both parts share identical electrical characteristics and mechanical specifications. The MAX890LESA+ is preferred for new designs and ongoing production due to its active product status and ROHS3 compliance certification. The MAX890LESA remains available for legacy system support where existing inventory exists, though its obsolete status indicates limited future availability.

Selection between these parts should be based on supply chain requirements and regulatory compliance mandates. Systems requiring RoHS3 compliance must use MAX890LESA+. Legacy systems currently using MAX890LESA may continue operation with existing stock; however, transition planning to MAX890LESA+ is recommended for long-term sustainability.
