MAX706CPA Equivalent & Substitute Parts

Part Overview

The MAX706CPA is a power management integrated circuit (PMIC) functioning as a supervisor with push-pull, totem pole output configuration. It monitors a single voltage channel and provides active-low reset functionality with a 140ms minimum reset timeout. The device operates across the 0°C to 70°C temperature range and is packaged in an 8-DIP through-hole format.

The MAX706CPA is classified as obsolete. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production requirements for systems utilizing this supervisor IC.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MAX706CPA is determined by the following critical parameters:

• Voltage Threshold: 4.4V (all substitutes must match this specification)
• Number of Voltages Monitored: 1 channel (single-channel supervision required)
• Output Configuration: Push-Pull, Totem Pole (output stage topology must be identical)
• Reset Logic: Active Low (reset polarity must match)
• Package / Case: 8-DIP (0.300", 7.62mm) (physical form factor and pin count must be compatible)
• Mounting Type: Through Hole (PCB assembly method must be compatible)
• Supplier Device Package: 8-PDIP (electrical and mechanical interface must align)

The substitute parts listed below satisfy all critical electrical and mechanical parameters. Variations in reset timeout, operating temperature range, product status, and compliance certifications are noted but do not preclude functional substitution when application requirements permit.

Engineering Selection Recommendations

MAX706CPA+ (Direct Manufacturer Upgrade)

The MAX706CPA+ is the direct successor to the MAX706CPA, maintaining identical electrical specifications and package configuration. Product status is active with ROHS3 compliance. This part is the primary recommendation for new designs and production continuity where RoHS compliance is required.

MAX709MCPA+ (Parametric Equivalent)

The MAX709MCPA+ satisfies all critical electrical and mechanical parameters. Product status is active with ROHS3 compliance. The base product number differs (MAX709 versus MAX706), but functional equivalence is established through matching voltage threshold, output configuration, reset logic, and package specifications. This part is suitable for applications where the MAX706CPA+ is unavailable.

ADM706ANZ (Manufacturer-Recommended Alternative)

The ADM706ANZ is an Analog Devices alternative offering extended operating temperature range (-40°C to 85°C) and ROHS3 compliance. Reset timeout is specified at 160ms minimum, which exceeds the MAX706CPA specification of 140ms minimum. This part is appropriate for applications requiring wider temperature operation or when supply constraints necessitate alternative sourcing.

Frequently Asked Questions (FAQ)

Q: Can MAX706CPA+ be used as a direct replacement for MAX706CPA?

A: Yes. The MAX706CPA+ maintains identical electrical specifications, package configuration, and pin compatibility. The primary difference is product status (active versus obsolete) and RoHS compliance (ROHS3 versus non-compliant). Functional substitution is direct.

Q: What is the difference between MAX706CPA and MAX709MCPA+?

A: Both parts share identical voltage threshold (4.4V), output configuration (push-pull, totem pole), reset logic (active low), reset timeout (140ms minimum), and package specifications (8-DIP). The base product numbers differ (MAX706 versus MAX709), but electrical and mechanical compatibility is established. Both are suitable for the same application requirements.

Q: Why does ADM706ANZ have a different reset timeout specification?

A: The ADM706ANZ specifies 160ms minimum reset timeout compared to 140ms minimum for the MAX706CPA. This represents a longer timeout duration. Applications requiring the exact 140ms specification should verify that the extended timeout does not impact system behavior. The ADM706ANZ is otherwise electrically and mechanically compatible.

Q: Can these parts be used interchangeably on the same PCB?

A: Yes. All substitute parts share identical package specifications (8-DIP, 0.300" spacing, 7.62mm pitch) and through-hole mounting requirements. Pin-to-pin compatibility is established. PCB layout modifications are not required for substitution.

Q: What compliance differences exist between the main part and substitutes?

A: The MAX706CPA is RoHS non-compliant. All substitute parts (MAX706CPA+, MAX709MCPA+, ADM706ANZ) are ROHS3 compliant. If RoHS compliance is a design requirement, any of the substitute parts satisfy this criterion. If legacy non-compliant parts are required, the original MAX706CPA must be sourced.

Q: Does operating temperature range affect substitution eligibility?

A: The MAX706CPA, MAX706CPA+, and MAX709MCPA+ operate across 0°C to 70°C. The ADM706ANZ extends this range to -40°C to 85°C. If the application operates within 0°C to 70°C, all parts are suitable. If extended temperature operation is required, the ADM706ANZ is the appropriate selection.
