MAX704CSA Equivalent & Substitute Parts

Part Overview

The MAX704CSA is a supervisor integrated circuit from Analog Devices Inc./Maxim Integrated designed for battery backup circuit applications. It functions as a single-channel power supply monitor with push-pull totem pole output and active-low reset functionality. The device is currently classified as obsolete, making equivalent and substitute parts necessary for ongoing system maintenance, redesigns, and new production runs where this functionality is required.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MAX704CSA are qualified based on the following critical parameters that must match or exceed the original specification:

• Single voltage monitoring channel
• 4.4V threshold voltage
• Push-pull totem pole output configuration
• Active-low reset logic
• 140ms minimum reset timeout
• 8-SOIC surface mount package
• Operating temperature range compatibility
• Moisture sensitivity level MSL 1

Parts are grouped into three categories: direct manufacturer equivalents (same base product with different packaging or compliance status), parametric equivalents (different manufacturer base product with identical electrical specifications), and manufacturer-recommended alternatives (cross-manufacturer substitutes with compatible functionality).

Parameter Comparison

Engineering Selection Recommendations

MAX704CSA+ (Direct Equivalent - Recommended for RoHS Compliance)

The MAX704CSA+ is the direct successor to the MAX704CSA from the same manufacturer. It maintains identical electrical specifications and package configuration while offering ROHS3 compliance. This part is currently in active production status with substantial inventory availability. Selection of MAX704CSA+ is appropriate for new designs and production runs requiring regulatory compliance.

MAX692ACSA+ (Parametric Equivalent - Active Status)

The MAX692ACSA+ provides identical electrical performance across all critical parameters: single-channel voltage monitoring, 4.4V threshold, push-pull totem pole output, active-low reset with 140ms timeout, and 8-SOIC packaging. This part carries active product status and ROHS3 compliance. The MAX692 base product number indicates a different device family within the Maxim supervisor IC portfolio, but functional equivalence is maintained for this application.

MAX802MCSA+ (Parametric Equivalent - Obsolete Status)

The MAX802MCSA+ matches all electrical specifications and package requirements of the MAX704CSA. However, this part is classified as obsolete, similar to the original MAX704CSA. Selection of this substitute is not recommended for new designs or long-term production applications due to end-of-life status.

STM704M6F (Cross-Manufacturer Alternative - Extended Temperature Range)

The STM704M6F from STMicroelectronics provides functional equivalence across all critical electrical parameters and maintains the 8-SOIC package format. This part offers an extended operating temperature range of -40°C to 85°C compared to the 0°C to 70°C range of the MAX704CSA, providing additional thermal margin for demanding applications. The STM704M6F is in active production with ROHS3 compliance and represents a viable cross-manufacturer alternative.

Frequently Asked Questions (FAQ)

Q: Can MAX704CSA+ be used as a direct replacement for MAX704CSA?

A: Yes. The MAX704CSA+ maintains identical electrical specifications, package configuration, and functional behavior. The primary difference is product status (active versus obsolete) and RoHS compliance (ROHS3 versus non-compliant). Pin-for-pin compatibility is maintained.

Q: What is the difference between MAX692ACSA+ and MAX704CSA?

A: Both devices share identical electrical specifications for voltage threshold (4.4V), output configuration (push-pull totem pole), reset logic (active low), reset timeout (140ms minimum), and package format (8-SOIC). The base product numbers (MAX692 versus MAX704) indicate different device families within the Maxim supervisor IC product line, but functional equivalence is complete for this application.

Q: Is STM704M6F suitable for applications requiring extended temperature operation?

A: The STM704M6F operates across -40°C to 85°C, exceeding the 0°C to 70°C range of MAX704CSA. If your application requires operation beyond 0°C to 70°C, the STM704M6F provides additional thermal margin. All other electrical specifications remain equivalent.

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

A: Yes. All substitute parts listed are packaged in 8-SOIC (0.154", 3.90mm Width) surface mount configuration, maintaining PCB layout and assembly compatibility with the original MAX704CSA design.

Q: Which substitute part should be selected for new production designs?

A: MAX704CSA+ is the recommended choice for new designs. It is the direct successor from the original manufacturer, maintains active product status, offers ROHS3 compliance, and provides the longest supply chain stability. STM704M6F is a viable alternative if extended temperature range is required.

Q: What is the significance of RoHS compliance status?

A: The original MAX704CSA is RoHS non-compliant. All substitute parts (MAX704CSA+, MAX692ACSA+, MAX802MCSA+, and STM704M6F) are ROHS3 compliant. For applications subject to RoHS regulations or customer requirements, selection of a ROHS3-compliant substitute is necessary.
