Substitute Part Grouping Explanation

Substitution of the MAX845ESA-T is determined by strict equivalence across the following critical parameters:

• Functional Classification: Transformer Driver PMIC
• Package Type: 8-SOIC (0.154", 3.90mm Width)
• Mounting Technology: Surface Mount
• Electrical Specifications: Voltage supply range 2.5V ~ 6V; supply current 1.1mA
• Operating Temperature Range: -40°C ~ 85°C
• Compliance Standards: ROHS3 Compliant; REACH Unaffected; MSL Level 1

The substitute part MAX845ESA+T maintains identical electrical and mechanical specifications, ensuring direct functional compatibility. The primary distinction is product status and packaging format availability.

Parameter Comparison

Engineering Selection Recommendations

The MAX845ESA+T is the direct equivalent substitute for the MAX845ESA-T. Both parts share identical electrical and mechanical specifications, including supply voltage range, supply current, operating temperature range, and package configuration. The MAX845ESA+T maintains ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment.

The primary advantage of selecting MAX845ESA+T is its active product status, providing assured long-term availability and supply chain continuity. The MAX845ESA-T, classified as obsolete, presents supply risk and potential discontinuation. The MAX845ESA+T is available in Cut Tape and Digi-Reel packaging formats, supporting both prototype and production volume requirements.
