MAX704SESA-T Equivalent & Substitute Parts

Part Overview

The MAX704SESA-T is a supervisor integrated circuit from Analog Devices Inc./Maxim Integrated, classified as a Power Management (PMIC) device. It functions as a battery backup circuit supervisor with push-pull, totem pole output configuration, monitoring a single voltage channel with a 2.925V threshold. The device operates across the industrial temperature range of -40°C to 85°C and is packaged in an 8-SOIC surface mount package.

The MAX704SESA-T is currently listed as obsolete. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production requirements for applications utilizing this supervisor topology.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MAX704SESA-T are identified based on strict electrical and mechanical parameter matching within the Power Management (PMIC) category. The substitution criteria are:

• Single voltage channel monitoring capability
• 2.925V voltage threshold specification
• Push-pull, totem pole output configuration
• Active low reset logic with 140ms minimum reset timeout
• Industrial temperature range operation (-40°C to 85°C)
• 8-SOIC surface mount package with identical physical dimensions (0.154", 3.90mm width)
• Moisture Sensitivity Level 1 (Unlimited)

Two substitute parts meet these criteria: MAX704SESA+T (direct packaging variant) and MAX690SESA+T (parametric equivalent from the MAX690 base product line).

Parameter Comparison

Engineering Selection Recommendations

The MAX704SESA-T is obsolete and no longer in active production. Both substitute parts maintain identical electrical and mechanical specifications, ensuring functional compatibility in existing designs.

MAX704SESA+T is the direct substitute, representing the same base product (MAX704) in active production status with Tape & Reel packaging. This part is recommended for designs requiring minimal change and direct form-fit-function replacement.

MAX690SESA+T is a parametric equivalent from the MAX690 base product line. It meets all electrical and mechanical requirements and is available in active production status with Tape & Reel packaging.

Both substitute parts are ROHS3 compliant, addressing regulatory requirements that the original MAX704SESA-T does not meet. Selection between the two substitutes should be based on availability, lead time, and supply chain preferences, as electrical performance and physical compatibility are equivalent.

Frequently Asked Questions (FAQ)

Q: Can MAX704SESA+T directly replace MAX704SESA-T in production?

A: Yes. MAX704SESA+T is electrically and mechanically identical to MAX704SESA-T. The primary difference is product status (active vs. obsolete) and packaging format (Tape & Reel vs. bulk). Pin configuration, electrical specifications, and package dimensions are identical, enabling direct substitution.

Q: What is the difference between MAX704SESA+T and MAX690SESA+T?

A: Both parts are parametric equivalents with identical electrical specifications and package dimensions. The difference is the base product line (MAX704 vs. MAX690). Both are suitable substitutes for the obsolete MAX704SESA-T. Selection should be based on supply availability and lead time.

Q: Are the substitute parts compatible with the original PCB layout?

A: Yes. Both MAX704SESA+T and MAX690SESA+T use the 8-SOIC package with identical physical dimensions (0.154", 3.90mm width). No PCB layout modifications are required.

Q: What is the significance of the packaging designation change from "-" to "+T"?

A: The "-T" suffix indicates Tape & Reel packaging format, which is standard for active production parts. The original MAX704SESA-T used bulk packaging. Tape & Reel packaging is suitable for automated assembly processes and is the standard format for both substitute parts.

Q: Are the substitute parts RoHS compliant?

A: Yes. Both MAX704SESA+T and MAX690SESA+T are ROHS3 compliant. The original MAX704SESA-T is RoHS non-compliant. This compliance upgrade may be required for new designs or regulatory requirements.

Q: Do the substitute parts have the same moisture sensitivity level?

A: Yes. All three parts (original and both substitutes) have Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity restrictions for storage and handling.
