MAX730AESA+ Equivalent & Substitute Parts

Part Overview

The MAX730AESA+ is a buck switching regulator IC manufactured by Analog Devices Inc./Maxim Integrated, designed for step-down voltage conversion applications. This positive fixed 5V output device delivers 450mA output current in an 8-SOIC surface mount package. The part is currently in active production status with 815 units available in new original inventory. Alternative components may be required due to supply constraints, design revisions, or procurement preferences while maintaining identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MAX730AESA+ is determined by strict equivalence across the following critical parameters:

• Input voltage range: 5.2V minimum to 11V maximum
• Fixed output voltage: 5V
• Output current capacity: 450mA
• Package type: 8-SOIC (0.154", 3.90mm Width)
• Switching frequency: 170kHz
• Operating temperature range: -40°C to 85°C
• Topology: Buck (step-down)
• Output configuration: Positive fixed

Only components matching all these specifications across electrical performance and physical packaging qualify as direct substitutes. The MAX730AESA+ represents the current direct equivalent within the Analog Devices MAX730 product line.

Parameter Comparison

Engineering Selection Recommendations

The MAX730AESA+ is the specified component for this application. Selection of alternative parts requires verification that the substitute maintains identical electrical characteristics (input/output voltage, current rating, switching frequency) and physical compatibility (8-SOIC package footprint). Active product status ensures continued availability and manufacturing support. ROHS3 compliance and MSL Level 1 rating confirm suitability for standard PCB assembly processes without moisture sensitivity constraints.

Frequently Asked Questions (FAQ)

Q: What makes a part a valid substitute for the MAX730AESA+? A: A valid substitute must match the input voltage range (5.2V–11V), fixed 5V output, 450mA current capacity, 170kHz switching frequency, 8-SOIC package, and -40°C to 85°C operating temperature. All electrical and mechanical parameters must be identical.

Q: Can I use a different output voltage regulator as a substitute? A: No. The MAX730AESA+ is specified for fixed 5V output. Substitutes must maintain this exact output voltage specification.

Q: Is the 8-SOIC package critical for substitution? A: Yes. The 8-SOIC (0.154", 3.90mm Width) package is a mechanical requirement for PCB compatibility. Alternative package types are not interchangeable without circuit board redesign.

Q: Does the MAX730AESA+ have any active substitutes from other manufacturers? A: Substitution eligibility is determined solely by matching the provided electrical and mechanical specifications. Only components meeting all parameters qualify as direct equivalents.

Q: What is the significance of the 170kHz switching frequency? A: The 170kHz switching frequency is a fixed characteristic of the MAX730AESA+ design. Substitutes must maintain this frequency to ensure proper circuit operation and EMI performance.

Q: Is RoHS3 compliance required for substitution? A: RoHS3 compliance is a regulatory requirement for this component. Substitutes must maintain equivalent compliance status for procurement and assembly processes.
