MAX5015ESA Equivalent & Substitute Parts

Part Overview

The MAX5015ESA is a flyback regulator controller IC manufactured by Analog Devices Inc./Maxim Integrated, designed for positive, isolation-capable step-up/step-down DC-DC conversion applications. This device operates as a transistor driver with a single output phase and is housed in an 8-SOIC surface mount package.

The MAX5015ESA is classified as obsolete. Locating equivalent or substitute components is necessary for ongoing production support, design updates, or inventory replenishment when original stock becomes unavailable.

Substitute Part Grouping Explanation

Substitution of the MAX5015ESA is determined by strict equivalence across the following critical parameters:

• Topology: Flyback regulator controller
• Output configuration: Positive, isolation-capable
• Function: Step-up/step-down DC-DC control
• Output type: Transistor driver with single output phase
• Voltage supply range: 13V ~ 36V
• Switching frequency: 275kHz
• Maximum duty cycle: 50%
• Control features: Enable and soft start functionality
• Operating temperature range: -40°C ~ 85°C
• Package: 8-SOIC surface mount
• Compliance: ROHS3 compliant, MSL 1

The substitute parts identified—MAX5015ESA+ and MAX5020ESA+—maintain identical electrical and mechanical specifications across all these parameters, ensuring functional interchangeability within the specified operating conditions.

Parameter Comparison

Engineering Selection Recommendations

All three parts—MAX5015ESA, MAX5015ESA+, and MAX5020ESA+—are classified as obsolete or not for new designs. Selection between these parts should be based on current inventory availability and compliance requirements.

MAX5015ESA+ and MAX5020ESA+ both carry REACH Unaffected status, providing additional regulatory documentation compared to the original MAX5015ESA. All three parts maintain ROHS3 compliance and MSL 1 rating, suitable for standard storage and handling conditions.

For applications requiring ongoing production support, MAX5020ESA+ currently maintains the highest inventory level (2292 pcs) among the three options, while maintaining identical electrical and mechanical specifications.

Frequently Asked Questions (FAQ)

Q: Can MAX5015ESA+ be used as a direct replacement for MAX5015ESA?

A: Yes. Both parts share identical electrical specifications, control features, package configuration, and operating parameters. The primary difference is product status classification and packaging format (tube for MAX5015ESA+).

Q: Is MAX5020ESA+ functionally equivalent to MAX5015ESA?

A: Yes. MAX5020ESA+ maintains all critical electrical and mechanical parameters required for substitution, including topology, output configuration, voltage supply range, switching frequency, duty cycle, control features, temperature range, and package type.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution is determined by matching topology (flyback), output configuration (positive, isolation-capable), function (step-up/step-down), output type (transistor driver), voltage supply range (13V ~ 36V), switching frequency (275kHz), maximum duty cycle (50%), control features (enable, soft start), operating temperature range (-40°C ~ 85°C), and package specification (8-SOIC surface mount).

Q: Are there any package or handling differences between these parts?

A: MAX5015ESA is supplied in standard packaging, while MAX5015ESA+ and MAX5020ESA+ are supplied in tube packaging. All three parts maintain identical MSL 1 rating and surface mount 8-SOIC package dimensions (0.154", 3.90mm width).

Q: Do all three parts meet current compliance standards?

A: All three parts are ROHS3 compliant with MSL 1 rating. MAX5015ESA+ and MAX5020ESA+ carry additional REACH Unaffected certification. All parts are classified as either obsolete or not for new designs.
