Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAX604ESA-T is determined by strict equivalence across the following critical parameters:

• Output configuration (Positive)
• Output type (Adjustable/Fixed)
• Number of regulators (1)
• Input voltage range (Max 11.5V)
• Output voltage range (Min 1.25V, Max 11V)
• Output current capability (500mA)
• Dropout voltage specification (0.82V @ 400mA)
• Quiescent current (35 µA)
• Control features (Enable function)
• Protection features (Over Current, Over Temperature, Reverse Polarity)
• Operating temperature range (-40°C ~ 85°C)
• Package type (8-SOIC)

The MAX604ESA+T meets all these criteria and qualifies as a direct substitute. The primary distinction between these parts is product status and packaging format.

Parameter Comparison

Engineering Selection Recommendations

The MAX604ESA+T is the direct substitute for the MAX604ESA-T. Both parts share identical electrical and mechanical specifications, with the primary advantage of the substitute being its active product status. The MAX604ESA+T is currently in production and maintains full availability through authorized distributors.

Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for new designs and legacy system support. The 8-SOIC package footprint is identical, permitting direct PCB layout compatibility without redesign.

Selection of the MAX604ESA+T is appropriate for applications requiring the specified voltage regulation, current delivery, and protection characteristics of the MAX604 series.

Frequently Asked Questions (FAQ)

Q: Can the MAX604ESA+T be used as a direct replacement for the MAX604ESA-T?

A: Yes. Both parts are electrically and mechanically identical across all specified parameters. The 8-SOIC package footprint, pinout, and functional characteristics are equivalent. Direct substitution on existing PCB designs is supported without modification.

Q: What is the primary difference between these two part numbers?

A: The MAX604ESA-T is classified as obsolete, while the MAX604ESA+T maintains active production status. The packaging format differs (tape and reel configuration for the substitute), but electrical performance and package dimensions remain identical.

Q: Are there any compliance or certification differences?

A: No. Both parts maintain identical RoHS3 compliance, REACH unaffected status, and moisture sensitivity level (MSL 1). Regulatory and environmental certifications are equivalent.

Q: What output voltage configurations are supported?

A: Both parts support adjustable and fixed output configurations with a minimum output voltage of 1.25V and maximum of 11V. The 3.3V fixed output option is available.

Q: Is the 8-SOIC package suitable for high-volume production?

A: Yes. The 8-SOIC package is a standard surface mount format with established manufacturing processes. The MAX604ESA+T is available in cut tape and Digi-Reel packaging formats suitable for automated assembly.
