MAX734CSA-T Equivalent & Substitute Parts

Part Overview

The MAX734CSA-T 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 range of 3V to 12V and delivers a fixed 12V output. The part is classified as obsolete, which necessitates identification of active equivalent alternatives to maintain supply chain continuity for new designs and production requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MAX734CSA-T is determined by strict alignment with the following electrical and mechanical parameters:

• Base Product Number: Both parts must share the MAX734 base designation
• Input Voltage Range: 3V ~ 12V (identical specification required)
• Output Voltage: 12V (fixed output, no variation permitted)
• Number of Outputs: Single output configuration
• Package / Case: 8-SOIC form factor with 0.154" (3.90mm) width
• Mounting Type: Surface Mount technology
• Operating Temperature Range: 0°C ~ 70°C

The MAX734CSA+T meets all electrical and mechanical substitution criteria. The primary distinction between the main part and substitute is packaging format (individual tube versus tape & reel) and product status (obsolete versus active).

Parameter Comparison

Engineering Selection Recommendations

The MAX734CSA+T is a direct functional equivalent to the MAX734CSA-T. Both components share identical electrical specifications, thermal operating range, and physical package dimensions. The substitute part is currently in active production status, ensuring long-term availability and supply chain reliability.

The MAX734CSA+T offers improved regulatory compliance through ROHS3 certification, whereas the original part is RoHS non-compliant. For applications subject to environmental or procurement regulations requiring RoHS compliance, the substitute part is the appropriate selection. The tape & reel packaging format of the substitute part is standard for automated assembly processes and high-volume production environments.

Frequently Asked Questions (FAQ)

Q: Can MAX734CSA+T be used as a direct replacement for MAX734CSA-T in existing designs?

A: Yes. Both parts are electrically and mechanically identical. They share the same input voltage range (3V ~ 12V), output voltage (12V), operating temperature range (0°C ~ 70°C), and 8-SOIC package footprint. No circuit modifications are required.

Q: What is the difference between the two part numbers?

A: The primary differences are packaging format and product status. MAX734CSA-T is supplied in tube packaging and is obsolete. MAX734CSA+T is supplied in tape & reel format and is in active production. The suffix designations (-T versus +T) indicate these packaging variations.

Q: Does the tape & reel packaging affect circuit performance?

A: No. Tape & reel packaging is a supply format only. It does not affect electrical performance, thermal characteristics, or functional behavior of the component.

Q: Is RoHS compliance a factor in substitution?

A: RoHS compliance is a regulatory and procurement consideration, not an electrical substitution factor. The MAX734CSA+T provides ROHS3 compliance, which may be required for certain applications or markets. The MAX734CSA-T is RoHS non-compliant. Component selection should align with applicable regulatory requirements.

Q: Are there any thermal or reliability differences between these parts?

A: No. Both parts operate across the identical temperature range (0°C ~ 70°C) and share the same moisture sensitivity level (MSL 1 - Unlimited). Thermal and reliability characteristics are equivalent.
