MAX708MJA Equivalent & Substitute Parts

Part Overview

The MAX708MJA is an active power-on reset supervisor integrated circuit manufactured by Analog Devices Inc./Maxim Integrated. This device monitors a single voltage supply and provides push-pull reset output control with a 140ms minimum reset timeout. The MAX708MJA is classified as a Simple Reset/Power-On Reset supervisor and operates across an extended temperature range of -55°C to 125°C, making it suitable for industrial and military applications requiring wide temperature performance.

The MAX708MJA is currently in active product status. Equivalent and substitute parts are identified based on matching core electrical specifications, functional characteristics, and compliance certifications while accounting for packaging and temperature rating variations.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MAX708MJA are identified based on the following core electrical and functional parameters that must remain constant:

Critical Matching Parameters:

• Base product number (MAX708 series)
• Single voltage monitoring channel
• 4.4V voltage threshold
• Push-pull output configuration
• Active High/Active Low reset logic
• 140ms minimum reset timeout
• Through-hole mounting technology
• ROHS3 compliance
• REACH unaffected status

Allowable Variations:

• Package type (CERDIP to PDIP conversion)
• Operating temperature range (extended to commercial grade)
• Packaging format (tube vs. other formats)

The MAX708CPA+ qualifies as a direct substitute based on identical electrical specifications and functional characteristics. The primary difference is the package type: MAX708MJA uses 8-CERDIP packaging, while MAX708CPA+ uses 8-PDIP packaging. Both are through-hole packages with equivalent pin configurations and electrical performance.

Parameter Comparison

Engineering Selection Recommendations

MAX708MJA Selection Criteria: The MAX708MJA is the appropriate choice for applications requiring extended temperature operation from -55°C to 125°C. This includes industrial control systems, military equipment, and automotive applications operating in extreme thermal environments. The 8-CERDIP ceramic package provides superior thermal performance and reliability in harsh conditions.

MAX708CPA+ Selection Criteria: The MAX708CPA+ is suitable for commercial-grade applications with operating temperatures limited to 0°C to 70°C. This part offers identical electrical functionality and reset characteristics as the MAX708MJA but in a plastic 8-PDIP package. The MAX708CPA+ is appropriate for consumer electronics, standard industrial equipment, and applications where extended temperature performance is not required.

Compliance and Certification: Both parts maintain ROHS3 compliance and REACH unaffected status, meeting current environmental and regulatory requirements. Both are active products with established supply chains and manufacturing support from Analog Devices Inc./Maxim Integrated.

Package Compatibility: Both 8-CERDIP and 8-PDIP packages share identical 0.300" (7.62mm) pitch and pin configurations, allowing direct substitution in through-hole PCB designs without layout modifications.

Frequently Asked Questions (FAQ)

Q: Can MAX708CPA+ replace MAX708MJA in all applications?

A: MAX708CPA+ can replace MAX708MJA only in applications where the operating temperature range does not exceed 0°C to 70°C. If your application requires operation below 0°C or above 70°C, the MAX708MJA with its -55°C to 125°C range is required.

Q: Are the package types interchangeable on the PCB?

A: Yes. Both 8-CERDIP (MAX708MJA) and 8-PDIP (MAX708CPA+) packages use identical 0.300" pitch and pin configurations. No PCB layout changes are required for substitution.

Q: Do both parts have the same electrical specifications?

A: Yes. Both MAX708MJA and MAX708CPA+ share identical voltage threshold (4.4V), reset timeout (140ms minimum), output configuration (push-pull), and reset logic (active high/active low).

Q: What is the difference between CERDIP and PDIP packaging?

A: CERDIP (ceramic DIP) uses a ceramic substrate and is typically specified for extended temperature ranges and harsh environments. PDIP (plastic DIP) uses a plastic substrate and is standard for commercial-grade applications. Both provide equivalent electrical performance within their respective temperature ratings.

Q: Are both parts RoHS compliant?

A: Yes. Both MAX708MJA and MAX708CPA+ are ROHS3 compliant and REACH unaffected, meeting current environmental regulations.

Q: What inventory levels are available?

A: MAX708MJA has 1609 pieces in stock. MAX708CPA+ has 3432 pieces in stock as new original inventory.
