MAX708CUA-T Equivalent & Substitute Parts

Part Overview

The MAX708CUA-T is a supervisor integrated circuit designed for power management applications, specifically functioning as a simple reset/power-on reset controller with push-pull output configuration. Manufactured by onsemi, this component monitors a single voltage channel and provides active high/active low reset functionality with a 140ms minimum reset timeout.

The MAX708CUA-T is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain design continuity, ensure supply chain reliability, and support ongoing production or maintenance requirements for systems utilizing this supervisor IC.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MAX708CUA-T are identified based on the following critical parameters that determine functional compatibility:

• Base Product Number: Both substitute parts share the MAX708 base designation, indicating the same core supervisor architecture and functional topology
• Number of Voltages Monitored: All parts monitor 1 voltage channel
• Output Configuration: All parts provide push-pull output with active high/active low reset capability
• Reset Timeout: All parts maintain 140ms minimum reset timeout specification
• Mounting Type: All parts are surface mount with compatible 8-pin package footprints (8-TSSOP, 8-MSOP)
• Moisture Sensitivity Level: All parts rated MSL 1 (Unlimited)

The substitute parts MAX708SCUA+ and MAX708SCUA+T differ from the main part in voltage threshold specification (2.93V versus 4.4V), operating temperature range (0°C ~ 70°C versus -40°C ~ 85°C), product status (Active versus Obsolete), and RoHS compliance status. These differences must be evaluated against specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

Selection between the MAX708CUA-T and its substitutes must account for the following factors:

Product Status and Supply Continuity: The MAX708CUA-T is obsolete, while MAX708SCUA+ and MAX708SCUA+T are active products with confirmed inventory availability. For new designs or ongoing production requiring long-term component supply, the active substitute parts provide superior supply chain assurance.

Regulatory Compliance: The MAX708CUA-T is RoHS non-compliant, whereas both substitute parts (MAX708SCUA+ and MAX708SCUA+T) are ROHS3 compliant. Applications subject to RoHS directives or customer requirements for compliant components necessitate use of the substitute parts.

Voltage Threshold Specification: The main part operates at 4.4V threshold, while substitutes operate at 2.93V threshold. This difference directly affects the voltage monitoring function and must align with the specific power supply voltage being supervised in the application circuit.

Operating Temperature Range: The MAX708CUA-T supports -40°C ~ 85°C operation, while substitutes support 0°C ~ 70°C. Applications requiring extended low-temperature operation below 0°C cannot use the substitute parts without thermal performance verification.

Packaging and Delivery Format: MAX708SCUA+ is supplied in Tube format, while MAX708SCUA+T is supplied in Cut Tape (CT) & Digi-Reel® format. Selection depends on assembly process requirements and volume handling procedures.

Frequently Asked Questions (FAQ)

Q: Can MAX708SCUA+ or MAX708SCUA+T be used as direct replacements for MAX708CUA-T?

A: Both parts share the same base product architecture (MAX708), single-channel monitoring, push-pull output, and 140ms reset timeout. However, the voltage threshold difference (2.93V versus 4.4V) and operating temperature range difference (-40°C ~ 85°C versus 0°C ~ 70°C) must be evaluated against specific application requirements. Direct substitution is only valid when the application voltage monitoring threshold and operating temperature range are compatible with the substitute part specifications.

Q: What is the primary reason to consider substitutes for the MAX708CUA-T?

A: The MAX708CUA-T is classified as obsolete. Substitute parts MAX708SCUA+ and MAX708SCUA+T are active products with confirmed inventory availability, ensuring long-term supply chain reliability and supporting ongoing production requirements.

Q: Are the substitute parts RoHS compliant?

A: Yes. Both MAX708SCUA+ and MAX708SCUA+T are ROHS3 compliant, whereas the main part MAX708CUA-T is RoHS non-compliant. Applications subject to RoHS directives require use of the compliant substitute parts.

Q: What is the difference between MAX708SCUA+ and MAX708SCUA+T?

A: Both parts are functionally identical with identical electrical specifications. The difference is in packaging format: MAX708SCUA+ is supplied in Tube format, while MAX708SCUA+T is supplied in Cut Tape (CT) & Digi-Reel® format. Selection depends on assembly process requirements and volume handling procedures.

Q: Can the substitute parts operate at the same temperature range as the MAX708CUA-T?

A: No. The MAX708CUA-T operates from -40°C ~ 85°C, while both substitute parts operate from 0°C ~ 70°C. Applications requiring operation below 0°C cannot use the substitute parts without additional thermal analysis and verification.

Q: Are the package footprints compatible between the main part and substitutes?

A: Yes. All three parts use compatible 8-pin surface mount packages (8-TSSOP, 8-MSOP with 0.118", 3.00mm width), ensuring PCB footprint compatibility.
