MAX708SCUA-T Equivalent & Substitute Parts

Part Overview

The MAX708SCUA-T is a single-channel power supply supervisor IC manufactured by onsemi, designed for power-on reset and simple reset applications. This component operates as a push-pull output supervisor with a 2.93V voltage threshold and 140ms minimum reset timeout. The part is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the MAX708SCUA-T is determined by the following critical parameters: single-channel voltage monitoring, 2.93V threshold voltage, push-pull output configuration, active high/active low reset capability, 140ms minimum reset timeout, and 8-pin surface mount packaging (8-TSSOP or 8-MSOP).

Substitute parts are grouped into two categories:

Direct Functional Equivalents (Same Electrical Characteristics): Parts that maintain identical voltage threshold, reset timeout, output type, and reset polarity specifications. These parts differ primarily in product status (active vs. obsolete) and RoHS compliance.

Parametric Equivalents with Output Variation: Parts that match all electrical parameters except output stage configuration. The STM708SDS6F uses a totem pole output instead of push-pull, which may require circuit-level evaluation for compatibility in specific applications.

Parameter Comparison

Engineering Selection Recommendations

For RoHS3 Compliant Designs: MAX708SCUA+T and MAX708SEUA+T are preferred substitutes. Both are manufactured by Analog Devices Inc./Maxim Integrated and maintain full electrical equivalence to the MAX708SCUA-T. MAX708SCUA+T is available in Cut Tape & Digi-Reel packaging with 10,200 units in stock. MAX708SEUA+T is available in Tape & Reel packaging with 34,300 units in stock and supports the full operating temperature range (-40°C ~ 85°C).

For Extended Temperature Range Applications: MAX708SEUA+T and STM708SDS6F both support -40°C ~ 85°C operating temperature, matching the original MAX708SCUA-T specification. MAX708SEUA+T maintains identical push-pull output configuration. STM708SDS6F uses totem pole output and requires circuit compatibility verification.

For Restricted Temperature Range (0°C ~ 70°C): MAX708SCUA+ is suitable when operating temperature constraints permit. This part is available in tube packaging with 2,100 units in stock.

For Non-RoHS Applications: MAX708SCUA+ remains available as an active product with RoHS3 compliance, though the original MAX708SCUA-T is RoHS non-compliant.

Frequently Asked Questions (FAQ)

Q: Can MAX708SCUA+ directly replace MAX708SCUA-T?

A: MAX708SCUA+ is electrically equivalent with identical voltage threshold (2.93V), reset timeout (140ms), and output configuration. The primary difference is operating temperature range: MAX708SCUA+ operates 0°C ~ 70°C versus MAX708SCUA-T at -40°C ~ 85°C. Substitution is valid only if your application operates within 0°C ~ 70°C.

Q: What is the difference between MAX708SCUA+T and MAX708SEUA+T?

A: Both parts are manufactured by Analog Devices Inc./Maxim Integrated with identical electrical specifications and RoHS3 compliance. The primary differences are packaging format (Cut Tape & Digi-Reel versus Tape & Reel) and inventory availability. MAX708SEUA+T supports the full -40°C ~ 85°C temperature range and has higher stock availability (34,300 units).

Q: Is STM708SDS6F a suitable replacement?

A: STM708SDS6F matches all critical parameters including voltage threshold, reset timeout, and temperature range. However, the output stage differs: STM708SDS6F uses totem pole output versus push-pull in the original part. Circuit-level compatibility must be verified before substitution, particularly regarding output impedance and load characteristics.

Q: Are all substitute parts in the same package?

A: All substitute parts use 8-pin surface mount packaging (8-TSSOP or 8-MSOP with 0.118" width, 3.00mm). Physical footprint compatibility is maintained across all listed substitutes.

Q: What is the RoHS compliance status of substitute parts?

A: All active substitute parts (MAX708SCUA+, MAX708SCUA+T, STM708SDS6F, MAX708SEUA+T) are ROHS3 compliant. The original MAX708SCUA-T is RoHS non-compliant. For designs requiring RoHS compliance, any of the active substitutes are suitable.
