MAX708CPA Equivalent & Substitute Parts

Part Overview

The MAX708CPA is a single-channel power supply supervisor IC manufactured by Analog Devices Inc./Maxim Integrated, designed for power-on reset and simple reset applications. This through-hole 8-DIP component monitors a single voltage threshold at 4.4V and provides push-pull output control with active high/active low reset capability.

The MAX708CPA 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 eligibility for the MAX708CPA is determined by strict equivalence across the following critical parameters:

Voltage threshold monitoring: 4.4V
Output type: Push-Pull configuration
Reset logic capability: Active High/Active Low
Package form factor: 8-DIP (0.300", 7.62mm)
Mounting technology: Through Hole
Functional classification: Simple Reset/Power-On Reset supervisor

Parts meeting these criteria are classified as direct substitutes. Variations in reset timeout duration, operating temperature range, product status, or compliance certifications do not disqualify substitution but must be evaluated against application requirements.

Engineering Selection Recommendations

MAX708CPA+ is the direct successor part from Analog Devices Inc./Maxim Integrated, maintaining identical electrical specifications and package configuration while transitioning to active product status and ROHS3 compliance. This part is recommended as the primary replacement for obsolete MAX708CPA inventory.

ADM708ANZ is an alternative supervisor IC from Analog Devices Inc. that meets all core functional and mechanical substitution criteria. This part offers an extended operating temperature range (-40°C ~ 85°C) and ROHS3 compliance. The reset timeout specification is 160ms minimum, compared to 140ms minimum for the MAX708CPA. Applications requiring the narrower 0°C ~ 70°C temperature range should verify compatibility with the extended range capability of ADM708ANZ.

Both substitute parts carry ROHS3 compliance and REACH unaffected status, providing improved regulatory alignment compared to the obsolete MAX708CPA.

Frequently Asked Questions (FAQ)

Q: Can MAX708CPA+ be used as a direct replacement for MAX708CPA?

A: Yes. MAX708CPA+ maintains identical voltage threshold (4.4V), output configuration (push-pull), reset logic (active high/active low), reset timeout (140ms minimum), operating temperature range (0°C ~ 70°C), and 8-DIP package specifications. The primary difference is product status (active vs. obsolete) and RoHS compliance (ROHS3 vs. non-compliant).

Q: What is the difference between MAX708CPA+ and ADM708ANZ?

A: Both parts share identical voltage threshold, output type, reset logic, and package form factor. ADM708ANZ offers an extended operating temperature range (-40°C ~ 85°C vs. 0°C ~ 70°C) and a slightly longer reset timeout specification (160ms minimum vs. 140ms minimum). Both are active products with ROHS3 compliance.

Q: Are there any package or pinout differences between these supervisor ICs?

A: No. All three parts use the 8-DIP (0.300", 7.62mm) through-hole package with identical supplier device package designation (8-PDIP). Direct board-level substitution is supported without layout modifications.

Q: Which part should be selected for new designs?

A: MAX708CPA+ or ADM708ANZ are both suitable for new designs. Selection depends on application temperature requirements. For standard industrial temperature range (0°C ~ 70°C), MAX708CPA+ provides exact electrical equivalence. For extended temperature range applications (-40°C ~ 85°C), ADM708ANZ is the appropriate choice.

Q: Are all substitute parts RoHS compliant?

A: MAX708CPA+ and ADM708ANZ are both ROHS3 compliant. The original MAX708CPA is RoHS non-compliant. Applications subject to RoHS requirements must use either substitute part.
