Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MAX708TESA-T are classified based on the following critical parameters that determine functional and mechanical compatibility:

Primary Substitution Criteria:

• Package / Case: 8-SOIC (0.154", 3.90mm Width) — mechanical and pin compatibility
• Number of Voltages Monitored: 1 — functional equivalence
• Output Configuration: Push-Pull, Push-Pull — signal output compatibility
• Reset Logic: Active High/Active Low — control signal compatibility
• Mounting Type: Surface Mount — assembly compatibility

Secondary Differentiation Parameters:

• Voltage - Threshold: Determines the supply voltage monitoring point (3.08V or 4.4V variants available)
• Reset Timeout: Minimum reset pulse duration (140ms or 160ms variants available)
• Operating Temperature Range: Application temperature requirements (-40°C ~ 85°C or 0°C ~ 70°C)
• Product Status: Active or Obsolete designation
• RoHS Compliance: Regulatory and environmental compliance status

Substitutes are grouped into two categories: Direct Parametric Equivalents (matching all critical parameters) and Similar Functional Alternatives (matching core functionality with parameter variations).

Parameter Comparison

Engineering Selection Recommendations

Recommended Primary Substitute: MAX708TESA+T

The MAX708TESA+T provides complete parametric equivalence to the MAX708TESA-T across all critical specifications: identical 3.08V voltage threshold, 140ms reset timeout, and -40°C ~ 85°C operating temperature range. This part is manufactured by Analog Devices Inc./Maxim Integrated under active product status with ROHS3 compliance, ensuring long-term availability and regulatory alignment. Packaging format (Cut Tape & Digi-Reel®) matches the original specification.

Alternative Substitutes Based on Application Requirements:

For applications operating within the 0°C ~ 70°C temperature range, MAX708TCSA+ or MAX708TCSA+T offer identical electrical parameters with reduced temperature specification, available in Tube or Tape & Reel packaging respectively.

For applications requiring 4.4V threshold monitoring, MAX708ESA+ or MAX708ESA+T provide equivalent functionality with higher voltage threshold, available in Tube or Cut Tape & Digi-Reel® packaging.

The ADM708TARZ-REEL (Analog Devices Inc.) offers functional compatibility with a 160ms reset timeout specification, representing a 20ms extension compared to the original 140ms minimum. This part is suitable for applications where extended reset pulse duration is acceptable or beneficial.

All recommended substitutes maintain identical package geometry (8-SOIC), mounting type (Surface Mount), and core functional architecture (single-channel push-pull supervisor with active high/active low reset logic).

Frequently Asked Questions (FAQ)

Q: Can MAX708TESA+T be used as a direct replacement for MAX708TESA-T?

A: Yes. The MAX708TESA+T matches all critical electrical and mechanical parameters: 3.08V threshold, 140ms reset timeout, -40°C ~ 85°C operating range, 8-SOIC package, and push-pull output configuration. The primary difference is product status (Active vs. Obsolete) and RoHS compliance (ROHS3 vs. non-compliant), both favoring the substitute.

Q: What is the difference between MAX708TESA+T and MAX708TCSA+T?

A: Both parts share identical electrical specifications (3.08V threshold, 140ms timeout, push-pull output). The primary difference is operating temperature range: MAX708TESA+T operates -40°C ~ 85°C, while MAX708TCSA+T operates 0°C ~ 70°C. Select based on your application's temperature requirements.

Q: Why would I choose MAX708ESA+T over MAX708TESA+T?

A: MAX708ESA+T is selected when your application requires monitoring a 4.4V supply voltage threshold instead of 3.08V. All other parameters remain identical. Verify your circuit's voltage monitoring requirement before substitution.

Q: Is the ADM708TARZ-REEL compatible with MAX708TESA-T?

A: The ADM708TARZ-REEL provides functional compatibility with one specification difference: 160ms reset timeout versus 140ms on the original part. This 20ms extension may be acceptable depending on your system's reset timing requirements. Verify reset pulse duration specifications in your application before substitution.

Q: What packaging options are available for substitutes?

A: Substitutes are available in multiple packaging formats: Cut Tape & Digi-Reel® (MAX708TESA+T, MAX708ESA+T, ADM708TARZ-REEL), Tube (MAX708TCSA+, MAX708ESA+), Tape & Reel (MAX708TCSA+T), and unspecified packaging (MAX708TESA+). Select based on your procurement and assembly requirements.

Q: Are all substitute parts RoHS compliant?

A: All recommended substitutes carry ROHS3 compliance status. The original MAX708TESA-T is RoHS non-compliant. If regulatory compliance is required for your application, substitution is necessary.

Q: Can I use these parts interchangeably in production?

A: Parts with identical electrical specifications (voltage threshold, reset timeout, temperature range) and package geometry are mechanically and functionally interchangeable. Verify parametric alignment with your circuit design before production implementation. Parts with differing voltage thresholds or temperature ranges require circuit validation.
