MAX701ESA Equivalent & Substitute Parts
Part Overview
The MAX701ESA is a supervisor integrated circuit designed for power management applications, specifically functioning as a simple reset/power-on reset controller. This component monitors a single voltage threshold at 4.65V and provides push-pull output control with active high/active low reset capability. The MAX701ESA is classified as obsolete, which necessitates identification of functionally equivalent alternatives for new designs and ongoing production requirements. Active substitute parts maintain identical electrical and mechanical specifications while offering current product status and improved compliance certifications.

Substitute Part Grouping Explanation
Substitution of the MAX701ESA is determined by strict equivalence across the following critical parameters:
- Voltage threshold monitoring: 1 channel at 4.65V
- Output stage configuration: Push-pull topology with active high/active low reset capability
- Reset timeout duration: 200ms minimum
- Operating temperature range: -40°C to 85°C
- Package form factor: 8-SOIC with 0.154" (3.90mm) width
- Electrical interface: Identical pin configuration and signal levels
The MAX701ESA+ qualifies as a direct substitute based on complete alignment with these parameters. The primary distinction between the main part and its substitute is product lifecycle status and compliance certification, not functional or electrical characteristics.

Engineering Selection Recommendations
The MAX701ESA+ is the direct functional equivalent for applications currently using the MAX701ESA. Selection of the MAX701ESA+ is supported by the following engineering considerations:
- Active product status ensures ongoing manufacturer support, availability, and supply chain continuity
- ROHS3 compliance certification meets current environmental and regulatory requirements for electronic components
- Identical electrical specifications and package form factor enable direct substitution without circuit redesign
- Moisture sensitivity level classification remains unchanged, maintaining compatibility with existing storage and handling procedures
- REACH compliance status is unaffected, preserving regulatory standing for international distribution
The MAX701ESA remains available in existing inventory but is not recommended for new designs due to obsolete product status and non-compliance with current RoHS standards.
Frequently Asked Questions (FAQ)
Q: Can the MAX701ESA+ be used as a direct replacement for the MAX701ESA in existing designs?
A: Yes. The MAX701ESA+ provides identical electrical performance, voltage threshold monitoring, output configuration, and package specifications. No circuit modifications are required for substitution.
Q: What is the primary difference between MAX701ESA and MAX701ESA+?
A: The MAX701ESA+ is an active product with ROHS3 compliance certification, while the MAX701ESA is classified as obsolete and RoHS non-compliant. Electrical and mechanical specifications are identical.
Q: Are there any package or pinout differences between these parts?
A: No. Both parts use the 8-SOIC package with 0.154" (3.90mm) width. Pinout and electrical interface are identical.
Q: What is the voltage threshold monitoring specification for these supervisor ICs?
A: Both the MAX701ESA and MAX701ESA+ monitor a single voltage channel with a threshold of 4.65V.
Q: What reset timeout duration is specified for these components?
A: Both parts provide a minimum reset timeout of 200ms.
Q: Are these parts suitable for operating temperature ranges below -40°C or above 85°C?
A: No. The specified operating temperature range for both parts is -40°C to 85°C (TA). Applications requiring operation outside this range require alternative component selection.
Q: What is the moisture sensitivity level for these supervisor ICs?
A: Both parts are classified as MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage and handling.
