MAX734ESA Equivalent & Substitute Parts

Part Overview

The MAX734ESA is a Flash Memory Voltage Regulator IC manufactured by Analog Devices Inc./Maxim Integrated, designed as a single-output converter for flash memory applications. This device operates with input voltage range of 3V to 12V and provides a fixed 12V output. The MAX734ESA is classified as obsolete, making identification of suitable substitute components essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MAX734ESA are identified based on the following critical parameters that determine functional compatibility:

• Input voltage range: 3V ~ 12V minimum compatibility
• Output voltage: 12V fixed output requirement
• Package type: 8-SOIC form factor (0.154", 3.90mm Width)
• Number of outputs: Single output configuration
• Mounting type: Surface Mount
• Operating temperature range: -40°C ~ 85°C

Two substitute parts meet these electrical and mechanical criteria: the MAX734ESA+ (direct manufacturer upgrade) and the TPS6734ID (alternative manufacturer equivalent).

Parameter Comparison

Engineering Selection Recommendations

The MAX734ESA+ is the direct manufacturer equivalent and represents the primary substitute option. This part maintains identical electrical specifications and package configuration while offering active product status and ROHS3 compliance, addressing the obsolescence and regulatory limitations of the original MAX734ESA.

The TPS6734ID from Texas Instruments provides an alternative cross-manufacturer substitute. This device meets all critical electrical and mechanical compatibility requirements, including identical package form factor, operating temperature range, and output voltage specification (12.12V nominal, functionally equivalent to 12V). The TPS6734ID is actively manufactured and ROHS3 compliant. The input voltage range extends to 2.7V minimum, providing broader input compatibility than the original specification.

Both substitute parts are suitable for direct replacement in applications currently using the MAX734ESA, with selection based on supply chain availability and design preference for manufacturer continuity or alternative sourcing.

Frequently Asked Questions (FAQ)

Q: Can the MAX734ESA+ be used as a direct replacement for MAX734ESA?

A: Yes. The MAX734ESA+ maintains identical electrical specifications (3V ~ 12V input, 12V output, single output) and package configuration (8-SOIC). The primary differences are active product status and ROHS3 compliance.

Q: What is the output voltage tolerance of the TPS6734ID compared to the MAX734ESA?

A: The TPS6734ID specifies 12.12V fixed output versus the MAX734ESA's 12V output. This 0.12V variance is within typical application tolerance for 12V regulated supplies and does not affect functional compatibility for flash memory voltage regulation applications.

Q: Are both substitute parts available in the same package?

A: Yes. Both MAX734ESA+ and TPS6734ID are packaged in 8-SOIC (0.154", 3.90mm Width) form factor, enabling direct PCB footprint compatibility.

Q: What is the minimum input voltage for the TPS6734ID?

A: The TPS6734ID accepts input voltage from 2.7V minimum, compared to 3V minimum for the MAX734ESA. This provides extended low-voltage operation capability.

Q: Does the obsolete status of MAX734ESA affect its functionality?

A: Obsolete status indicates the manufacturer has discontinued production. Existing inventory may be available, but long-term supply cannot be guaranteed. Substitution with active products (MAX734ESA+ or TPS6734ID) is recommended for new designs and ongoing production requirements.

Q: Are there RoHS compliance differences between the substitutes?

A: Yes. The MAX734ESA is RoHS non-compliant, while both MAX734ESA+ and TPS6734ID are ROHS3 compliant. For applications requiring RoHS compliance, either substitute part is suitable.
