MAX5019ESA Equivalent & Substitute Parts

Part Overview

The MAX5019ESA 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 MAX5019ESA carries an obsolete product status, making it necessary to identify equivalent substitute components for new designs and ongoing production requirements. Locating compatible alternatives ensures design continuity and supply chain reliability.

Substitute Part Grouping Explanation

Substitute parts for the MAX5019ESA are identified based on strict electrical and mechanical parameter matching. The following criteria determine substitution eligibility:

Critical Matching Parameters:

• Topology: Flyback
• Function: Step-Up/Step-Down
• Output Configuration: Positive, Isolation Capable
• Number of Outputs: 1
• Voltage - Supply (Vcc/Vdd): 13V ~ 36V
• Frequency - Switching: 275kHz
• Duty Cycle (Max): 85%
• Operating Temperature: -40°C ~ 85°C (TA)
• Package / Case: 8-SOIC (0.154", 3.90mm Width)
• Mounting Type: Surface Mount

The MAX5014ESA+ meets all critical electrical and mechanical parameters required for direct substitution in applications currently using the MAX5019ESA.

Parameter Comparison

Engineering Selection Recommendations

The MAX5014ESA+ serves as the primary substitute for the MAX5019ESA. Both components are manufactured by Analog Devices Inc./Maxim Integrated and share identical electrical specifications and package configurations.

The MAX5019ESA is classified as obsolete, while the MAX5014ESA+ carries a "Not For New Designs" status. Both components maintain ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1), ensuring regulatory and environmental compatibility.

For applications currently deployed with the MAX5019ESA, the MAX5014ESA+ provides direct functional equivalence. The substitute maintains the same supply voltage range (13V ~ 36V), switching frequency (275kHz), duty cycle capability (85%), and operating temperature range (-40°C ~ 85°C).

Frequently Asked Questions (FAQ)

Q: Can the MAX5014ESA+ be used as a direct replacement for the MAX5019ESA?

A: Yes. The MAX5014ESA+ matches all critical electrical parameters including topology, function, output configuration, supply voltage range, switching frequency, duty cycle, operating temperature, and package type. No circuit modifications are required for substitution.

Q: Are there package differences between these parts?

A: No. Both the MAX5019ESA and MAX5014ESA+ use the 8-SOIC package with identical dimensions (0.154" width, 3.90mm). Surface mount assembly processes remain unchanged.

Q: What is the difference in product status between these parts?

A: The MAX5019ESA is classified as obsolete, indicating it is no longer manufactured. The MAX5014ESA+ carries a "Not For New Designs" status, meaning it remains available but is not recommended for new product development. For existing applications, the MAX5014ESA+ provides continued supply availability.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the MAX5019ESA and MAX5014ESA+ are ROHS3 compliant with MSL 1 (unlimited moisture sensitivity). Regulatory and environmental requirements are identical.

Q: Are the control features identical?

A: Yes. Both parts include enable and soft start control features with no synchronous rectifier or clock sync capability.
