MAX734CSA Equivalent & Substitute Parts

Part Overview

The MAX734CSA 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 component operates with input voltage ranging from 3V to 12V and delivers a 12V output in an 8-SOIC surface mount package.

The MAX734CSA is classified as obsolete. Due to its discontinued status, identifying equivalent and substitute parts is essential for system redesign, maintenance, and long-term component sourcing strategies.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAX734CSA is determined by strict equivalence across the following critical parameters:

• Input voltage range: 3V ~ 12V
• Output voltage: 12V
• Number of outputs: 1
• Package type: 8-SOIC with identical physical dimensions (0.154", 3.90mm Width)
• Mounting type: Surface Mount
• Operating temperature range: 0°C ~ 70°C
• Moisture sensitivity level: 1 (Unlimited)
• Base product series: MAX734

The MAX734CSA+ meets all these criteria and is identified as a direct substitute. Both parts share identical electrical specifications, package geometry, and thermal operating range, enabling pin-for-pin and functional replacement.

Parameter Comparison

Engineering Selection Recommendations

The MAX734CSA+ is the direct substitute for the MAX734CSA. Both components are electrically and mechanically identical across all specified parameters. The primary distinction is product status: the MAX734CSA is obsolete, while the MAX734CSA+ is active and currently available.

An additional consideration is regulatory compliance. The MAX734CSA+ achieves ROHS3 compliance, whereas the original MAX734CSA is RoHS non-compliant. For applications subject to RoHS regulations or environmental compliance requirements, the MAX734CSA+ provides the necessary certification alignment.

Both parts maintain REACH Unaffected status and identical ECCN and HTSUS classifications, confirming their equivalence for export and regulatory purposes.

Frequently Asked Questions (FAQ)

Q: Can the MAX734CSA+ be used as a direct replacement for the MAX734CSA?

A: Yes. The MAX734CSA+ is a direct pin-for-pin and functional equivalent. All electrical specifications, output voltage, input voltage range, operating temperature, and package dimensions are identical. No circuit modifications are required.
