MAX9030AUT-T Equivalent & Substitute Parts

Part Overview

The MAX9030AUT-T is a general-purpose comparator IC manufactured by Analog Devices Inc./Maxim Integrated, designed for rail-to-rail push-pull output applications in the 2.5V to 5.5V supply voltage range. This component is classified as obsolete, making equivalent substitutes necessary for new designs and ongoing production requirements. The part is housed in a SOT-23-6 surface mount package and complies with ROHS3 and REACH standards.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MAX9030AUT-T is determined by the following critical parameters:

• Supply Voltage Compatibility: Substitute parts must operate within or encompass the 2.5V ~ 5.5V range
• Output Configuration: Push-pull, rail-to-rail output capability is required
• Package Type: Surface mount packages with compatible pinouts and thermal characteristics
• General Purpose Comparator Function: Single-element comparator topology
• Compliance Standards: ROHS3 and REACH compliance maintained

The substitute parts listed below meet these core electrical and mechanical requirements, though individual parameter variations exist within acceptable engineering tolerances for general-purpose comparator applications.

Parameter Comparison

Engineering Selection Recommendations

MAX9030AUT+T (Analog Devices Inc./Maxim Integrated): This is the direct parametric equivalent with identical electrical specifications and package configuration. Product status is active with 5800 units in stock. This part is the primary recommendation for direct replacement in existing designs.

AZV3001FZ4-7 (Diodes Incorporated): Offers extended lower supply voltage capability (1.6V minimum) and superior input bias current performance (1pA). However, the package differs (6-XFDFN versus SOT-23-6), requiring PCB layout modification. Operating temperature maximum is reduced to 85°C. Moisture sensitivity level is elevated to MSL 3. This part is suitable for new designs where package change is acceptable and lower voltage operation is beneficial.

LMV7219M7/NOPB (Texas Instruments): Provides faster propagation delay (20ns versus 228ns) and operates within the 2.7V to 5V range. Package is 5-TSSOP, SC-70-5, requiring PCB redesign. Quiescent current is significantly higher at 1.8mA. Operating temperature maximum is 85°C. This part is applicable for timing-critical applications where the package change and higher power consumption are acceptable.

LMV7219M5 (National Semiconductor): Limited parameter data available. Operates in the 2.7V to 5V range. Suitable only when other options are unavailable and full parameter verification is conducted independently.

Frequently Asked Questions (FAQ)

Q: Can MAX9030AUT+T be used as a direct drop-in replacement for MAX9030AUT-T?

A: Yes. MAX9030AUT+T is the parametric equivalent with identical electrical specifications, package configuration (SOT-23-6), and pin assignment. The only difference is product status (active versus obsolete) and packaging format (cut tape and digi-reel availability).

Q: What are the key differences between MAX9030AUT-T and AZV3001FZ4-7?

A: The primary differences are package type (SOT-23-6 versus 6-XFDFN), operating temperature range (-40°C to 125°C versus -40°C to 85°C), and moisture sensitivity level (MSL 1 versus MSL 3). The AZV3001FZ4-7 offers superior input bias current (1pA) and lower minimum supply voltage (1.6V). PCB layout modification is required for package change.

Q: Is LMV7219M7/NOPB compatible with MAX9030AUT-T applications?

A: Electrical compatibility exists within the overlapping supply voltage range (2.7V to 5V). However, the package differs (5-TSSOP, SC-70-5 versus SOT-23-6), requiring PCB redesign. Quiescent current is substantially higher (1.8mA versus 55µA), affecting power budget calculations. Operating temperature maximum is reduced to 85°C.

Q: What is the impact of different package types on substitution?

A: Package differences require PCB layout modification, including trace routing, via placement, and thermal management considerations. Pinout verification is mandatory before implementation. Moisture sensitivity levels may differ, affecting storage and handling requirements during assembly.

Q: Are all substitute parts ROHS3 and REACH compliant?

A: MAX9030AUT+T, AZV3001FZ4-7, and LMV7219M7/NOPB are confirmed ROHS3 and REACH compliant. LMV7219M5 compliance status is not specified in available data.

Q: Which substitute part is recommended for new designs?

A: Selection depends on design requirements. For direct replacement with minimal PCB changes, use MAX9030AUT+T. For extended lower voltage operation, use AZV3001FZ4-7. For timing-critical applications requiring faster propagation delay, use LMV7219M7/NOPB.
