MAX791CPE Equivalent & Substitute Parts

Part Overview

The MAX791CPE is a supervisor integrated circuit designed for battery backup circuit applications, manufactured by Analog Devices Inc./Maxim Integrated. This device monitors a single voltage channel and provides push-pull, totem pole output with active low reset functionality. The MAX791CPE is classified as obsolete, which necessitates identification of equivalent substitute components for ongoing system support and new designs. Finding suitable alternatives ensures design continuity and supply chain reliability.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAX791CPE is determined by strict equivalence across the following critical parameters:

• Single voltage channel monitoring capability
• 4.65V voltage threshold setting
• Push-pull, totem pole output configuration
• Active low reset with 140ms minimum timeout
• 16-DIP through-hole package format
• Operating temperature range of 0°C to 70°C

The MAX791CPE+ qualifies as a direct substitute based on identical electrical specifications, package configuration, and functional characteristics. The primary distinction between these parts is product status and compliance certification, not electrical or mechanical performance.

Parameter Comparison

Engineering Selection Recommendations

The MAX791CPE+ is the direct equivalent substitute for the MAX791CPE. Both components share identical electrical specifications, functional characteristics, and physical packaging. The MAX791CPE+ is preferred for new designs and ongoing production due to its active product status and ROHS3 compliance certification. The MAX791CPE remains available in existing inventory but is classified as obsolete by the manufacturer. Selection between these parts should be based on compliance requirements and supply chain availability rather than electrical performance, as both components are functionally interchangeable within the specified operating parameters.

Frequently Asked Questions (FAQ)

Q: Can the MAX791CPE+ directly replace the MAX791CPE in existing designs?

A: Yes. The MAX791CPE+ is electrically and mechanically identical to the MAX791CPE. Both components feature the same 16-DIP package, voltage threshold, output configuration, and reset characteristics. Direct substitution is possible without circuit modification.

Q: What is the primary difference between MAX791CPE and MAX791CPE+?

A: The MAX791CPE+ is the active production variant with ROHS3 compliance certification. The MAX791CPE is classified as obsolete. Electrical and mechanical specifications are identical.

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

A: No. Both the MAX791CPE and MAX791CPE+ use the 16-DIP (0.300", 7.62mm) through-hole package format. PCB layout and mounting procedures are identical.

Q: Does the MAX791CPE+ meet current environmental compliance standards?

A: The MAX791CPE+ is ROHS3 compliant and REACH unaffected. The MAX791CPE is RoHS non-compliant. For applications requiring environmental compliance certification, the MAX791CPE+ is the appropriate selection.

Q: What is the moisture sensitivity level for these components?

A: Both the MAX791CPE and MAX791CPE+ have a Moisture Sensitivity Level (MSL) of 1, indicating unlimited shelf life without moisture control requirements.
