MAX708RESA-T Equivalent & Substitute Parts

Part Overview

The MAX708RESA-T is a supervisor integrated circuit designed for power management applications, functioning as a single-channel reset/power-on reset controller with push-pull output configuration. Manufactured by onsemi, this component operates across an extended temperature range of -40°C to 85°C and is packaged in an 8-SOIC surface mount package. The part is currently classified as obsolete, necessitating identification of active equivalent alternatives for new designs and ongoing production requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAX708RESA-T is determined by the following critical parameters: voltage threshold setting, operating temperature range, reset timeout specification, output configuration, and package compatibility. The MAX708 family provides multiple variants with different voltage thresholds (2.63V or 4.4V) and temperature ratings (industrial -40°C to 85°C or commercial 0°C to 70°C).

Direct parametric equivalents maintain identical voltage thresholds (2.63V), reset timeout (140ms minimum), output configuration (push-pull), and extended temperature range (-40°C to 85°C). These parts are functionally interchangeable with the original MAX708RESA-T in applications requiring these specific electrical characteristics.

Similar alternatives with different voltage thresholds (4.4V) or restricted temperature ranges (0°C to 70°C) are suitable only for applications where the design specifications permit these parameter variations. All substitute parts share the same 8-SOIC package footprint, single-channel monitoring architecture, and push-pull output topology.

Parameter Comparison

Engineering Selection Recommendations

For direct replacement of the MAX708RESA-T in applications requiring identical electrical specifications, MAX708RESA+T and MAX708RESA+ are parametric equivalents. Both parts are manufactured by Analog Devices Inc./Maxim Integrated, maintain the 2.63V voltage threshold and -40°C to 85°C operating range, and are currently in active production status. These parts achieve ROHS3 compliance, addressing the RoHS non-compliance limitation of the original component. Selection between MAX708RESA+T (Cut Tape & Digi-Reel packaging) and MAX708RESA+ (Tube packaging) depends on procurement and assembly requirements.

For applications where the operating temperature range can be restricted to 0°C to 70°C, MAX708RCSA+T and MAX708RCSA+ provide active alternatives with identical voltage threshold and reset timeout specifications. These parts are suitable for commercial-grade applications and are available in Tape & Reel and Tube packaging options respectively.

MAX708ESA+T and MAX708ESA+ are functionally compatible alternatives only for designs where the voltage threshold can be adjusted to 4.4V. These parts maintain the extended temperature range and are available in multiple packaging formats.

All substitute parts maintain the 8-SOIC package footprint, ensuring mechanical compatibility with existing PCB layouts. Electrical compatibility is confirmed through matching output configuration, reset timeout, and single-channel monitoring architecture.

Frequently Asked Questions (FAQ)

Q: Can MAX708RESA+T be used as a direct replacement for MAX708RESA-T?

A: Yes. MAX708RESA+T is a parametric equivalent with identical voltage threshold (2.63V), operating temperature range (-40°C to 85°C), reset timeout (140ms minimum), and output configuration. The primary differences are manufacturer (Analog Devices Inc./Maxim Integrated versus onsemi) and improved RoHS3 compliance status.

Q: What is the difference between MAX708RESA+T and MAX708RCSA+T?

A: Both parts share the 2.63V voltage threshold and 140ms reset timeout. The primary difference is operating temperature range: MAX708RESA+T operates from -40°C to 85°C (industrial grade), while MAX708RCSA+T operates from 0°C to 70°C (commercial grade). Selection depends on the application's temperature requirements.

Q: Can MAX708ESA+T replace MAX708RESA-T?

A: MAX708ESA+T is mechanically and functionally compatible but has a different voltage threshold (4.4V versus 2.63V). Substitution is possible only if the application design permits adjustment to the higher voltage threshold. Electrical circuit modifications may be required.

Q: What packaging options are available for MAX708RESA+ equivalents?

A: MAX708RESA+T is supplied in Cut Tape (CT) & Digi-Reel® packaging, while MAX708RESA+ is supplied in Tube packaging. Both maintain the 8-SOIC package footprint. Selection depends on assembly equipment compatibility and procurement preferences.

Q: Are all substitute parts RoHS compliant?

A: All Analog Devices Inc./Maxim Integrated MAX708 variants listed are ROHS3 compliant. The original MAX708RESA-T is RoHS non-compliant. Substitution with any listed alternative improves regulatory compliance status.

Q: Do all substitute parts fit the same PCB footprint?

A: Yes. All substitute parts use the 8-SOIC (0.154", 3.90mm Width) package, ensuring mechanical compatibility with existing PCB layouts designed for MAX708RESA-T.
