MAX704CSA-T Equivalent & Substitute Parts

Part Overview

The MAX704CSA-T is a single-channel supervisor IC manufactured by Analog Devices Inc./Maxim Integrated, designed for battery backup circuit applications. This component provides push-pull, totem pole output with active-low reset functionality. The part is currently classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement continuity. Substitute parts maintain functional equivalence through matching electrical parameters and mechanical compatibility while offering active product status and improved availability.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MAX704CSA-T is determined by strict equivalence across the following critical parameters:

• Single voltage monitoring channel
• 4.4V threshold voltage
• Push-pull, totem pole output configuration
• Active-low reset with 140ms minimum timeout
• 8-SOIC surface mount package (0.154", 3.90mm width)
• ROHS3 compliance and MSL Level 1 rating

Three substitute parts meet these criteria and are grouped as follows:

Direct Manufacturer Equivalent: MAX704CSA+T represents the same base product (MAX704) with identical electrical specifications and packaging, differentiated only by tape & reel packaging format.

Parametric Equivalent: MAX692ACSA+T maintains all critical electrical parameters and mechanical compatibility despite different base product designation (MAX692 vs MAX704), enabling functional substitution.

Manufacturer-Recommended Alternative: STM704M6F from STMicroelectronics provides equivalent functionality across all monitored parameters with extended operating temperature range (-40°C to 85°C versus 0°C to 70°C).

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement: MAX704CSA+T is the primary substitute, offering identical electrical and mechanical specifications with active product status and higher current inventory availability (3100 pcs). This part maintains the same operating temperature range and is sourced from the original manufacturer.

For Parametric Substitution: MAX692ACSA+T provides full functional equivalence across all critical monitoring and reset parameters. The different base product number reflects internal manufacturer designation but does not affect circuit-level compatibility. This option is suitable when MAX704CSA+T availability is constrained.

For Extended Temperature Applications: STM704M6F from STMicroelectronics maintains all electrical equivalence while extending the operating temperature range to -40°C to 85°C. This part is appropriate for designs requiring enhanced thermal performance or wider environmental operating conditions. All compliance certifications (ROHS3, MSL Level 1) remain equivalent.

All three substitute parts are ROHS3 compliant with MSL Level 1 rating, ensuring compatibility with standard manufacturing and storage protocols.

Frequently Asked Questions (FAQ)

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

A: Yes. MAX704CSA+T is electrically and mechanically identical to MAX704CSA-T. The only difference is packaging format (tape & reel versus bulk). Both parts share the same 8-SOIC package, voltage threshold, reset timing, and output configuration.

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

A: Both parts are parametrically equivalent across all critical specifications: 1-channel voltage monitoring at 4.4V threshold, push-pull totem pole output, active-low reset with 140ms timeout, and 8-SOIC surface mount packaging. The base product designation differs (MAX704 versus MAX692), but this reflects internal manufacturer classification and does not affect functional compatibility.

Q: When should STM704M6F be selected instead of the Maxim alternatives?

A: STM704M6F is the appropriate choice when the application requires extended operating temperature range (-40°C to 85°C versus 0°C to 70°C). All other electrical parameters and mechanical specifications remain equivalent. This part is sourced from STMicroelectronics rather than Analog Devices/Maxim Integrated.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. MAX704CSA+T, MAX692ACSA+T, and STM704M6F are all ROHS3 compliant with MSL Level 1 moisture sensitivity rating, meeting standard environmental and regulatory requirements.

Q: Can these parts be used interchangeably on the same PCB?

A: Yes. All substitute parts use the identical 8-SOIC (0.154", 3.90mm width) surface mount package with the same pin configuration, voltage threshold, and output characteristics. No PCB layout or schematic modifications are required for substitution.

Q: What is the inventory status of each substitute part?

A: MAX704CSA+T has 3100 pcs in stock, MAX692ACSA+T has 1386 pcs in stock, and STM704M6F has 3700 pcs in stock. The original MAX704CSA-T (obsolete) has 2322 pcs available.
