MAX704TESA Equivalent & Substitute Parts

Part Overview

The MAX704TESA is a supervisor integrated circuit from Analog Devices Inc./Maxim Integrated designed for battery backup circuit applications. This single-channel voltage supervisor operates with a push-pull, totem pole output configuration and provides active-low reset functionality. The device is classified as obsolete, which necessitates identification of functionally equivalent alternatives for new designs or component replenishment in legacy systems. The MAX704TESA remains available in limited inventory, making substitute parts critical for production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAX704TESA is determined by strict equivalence across the following critical parameters:

• Voltage Monitoring Capability: Single-channel operation with 3.075V threshold
• Output Stage: Push-pull, totem pole configuration for direct logic-level signaling
• Reset Behavior: Active-low reset with 140ms minimum timeout
• Thermal Operating Range: -40°C to 85°C ambient temperature specification
• Package Footprint: 8-SOIC surface-mount package with 0.154" (3.90mm) width
• Regulatory Compliance: ROHS3 compliance and REACH unaffected status

The MAX704TESA+ qualifies as a direct substitute based on identical electrical specifications and package geometry. The primary distinction is product status and packaging format.

Parameter Comparison

Engineering Selection Recommendations

The MAX704TESA+ is the direct equivalent for the obsolete MAX704TESA. Both devices share identical electrical specifications, package geometry, and regulatory compliance certifications. The MAX704TESA+ maintains active product status with established supply availability, making it the appropriate selection for new production builds or component replacement in existing applications.

Both variants satisfy ROHS3 compliance requirements and REACH regulatory obligations. The 8-SOIC surface-mount package is consistent across both part numbers, ensuring PCB layout compatibility without redesign. The MSL rating of 1 (Unlimited) indicates no moisture sensitivity constraints during storage or handling.

Frequently Asked Questions (FAQ)

Q: Can the MAX704TESA+ be used as a direct replacement for the MAX704TESA?

A: Yes. The MAX704TESA+ is electrically and mechanically identical to the MAX704TESA. Both devices feature the same 3.075V threshold, push-pull totem pole output, active-low reset with 140ms timeout, and 8-SOIC package footprint. The primary difference is product status: MAX704TESA is obsolete while MAX704TESA+ is active.

Q: Are there any package or footprint differences between these parts?

A: No. Both the MAX704TESA and MAX704TESA+ use the 8-SOIC package with 0.154" (3.90mm) width. PCB layouts and assembly processes require no modification when substituting between these part numbers.

Q: What is the significance of the "+" suffix in MAX704TESA+?

A: The "+" suffix typically indicates a packaging or supply format variation. In this case, the MAX704TESA+ is supplied in tube packaging, whereas the original MAX704TESA may have used alternative packaging. The electrical specifications remain identical.

Q: Are both parts compliant with current regulatory standards?

A: Yes. Both the MAX704TESA and MAX704TESA+ are ROHS3 compliant and REACH unaffected. Both meet current environmental and hazardous substance restrictions for electronic components.

Q: What is the moisture sensitivity level, and does it affect storage?

A: Both parts carry an MSL rating of 1 (Unlimited), indicating no moisture sensitivity constraints. Standard component storage practices are sufficient; no special desiccant or controlled humidity environments are required.
