MAX812LEUS-T Equivalent & Substitute Parts

Part Overview

The MAX812LEUS-T is a single-channel power supply supervisor IC manufactured by Analog Devices Inc./Maxim Integrated, designed for power-on reset and supervisory functions in embedded systems. This component operates as a push-pull, totem pole output supervisor with a 4.63V threshold voltage and 140ms minimum reset timeout. The MAX812LEUS-T is classified as obsolete, making equivalent and substitute parts necessary for new designs and ongoing production support. Substitute parts maintain identical electrical and mechanical specifications while offering active product status and improved compliance certifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MAX812LEUS-T are qualified based on strict electrical and mechanical parameter matching. All substitute parts maintain the following critical specifications:

• Single-channel voltage monitoring at 4.63V threshold
• Push-pull, totem pole output configuration
• Active high reset logic with 140ms minimum timeout
• Surface mount SOT-143-4 package (TO-253-4, TO-253AA case)
• Operating temperature range of -40°C to 85°C
• Moisture sensitivity level 1 (unlimited shelf life)
• REACH unaffected status
• EAR99 export classification

Substitute parts are categorized as direct manufacturer equivalents (same base product line with different packaging) and parametric equivalents (different manufacturers with identical electrical performance). All substitute parts listed maintain active product status and ROHS3 compliance, addressing the obsolescence and compliance limitations of the original MAX812LEUS-T.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed maintain electrical and mechanical compatibility with the MAX812LEUS-T based on identical threshold voltage, output configuration, reset timing, and package specifications. Selection among substitute parts should be based on the following criteria:

MAX812LEUS+T is the direct equivalent from Analog Devices Inc./Maxim Integrated, offering the same manufacturer lineage with improved ROHS3 compliance and active product status. This part is suitable for designs requiring continuity with the original Maxim Integrated product line.

STM812LW16F from STMicroelectronics provides the highest inventory availability (36,300 units) and active product status with ROHS3 compliance. This part is suitable for high-volume production requirements.

ADM812LARTZ-REEL7 from Analog Devices Inc. offers parametric equivalence with ROHS3 compliance and active product status. This part is suitable for designs requiring Analog Devices sourcing with tape and reel packaging.

APX812-46UG-7 from Diodes Incorporated and MIC812LUY-TR from Microchip Technology are parametric equivalents with active product status and ROHS3 compliance. These parts are suitable for designs with multi-source qualification requirements.

All substitute parts comply with REACH regulations and carry EAR99 export classification. Selection should account for supply chain availability, preferred supplier agreements, and packaging format requirements for production processes.

Frequently Asked Questions (FAQ)

Q: Can MAX812LEUS+T be used as a direct replacement for MAX812LEUS-T?

A: Yes. MAX812LEUS+T is a direct equivalent from the same manufacturer with identical electrical specifications, threshold voltage (4.63V), output configuration (push-pull, totem pole), reset timing (140ms minimum), and package (SOT-143-4). The primary differences are improved ROHS3 compliance and active product status.

Q: What are the key parameters that determine substitutability?

A: Substitutability is determined by: single-channel voltage monitoring, 4.63V threshold voltage, push-pull totem pole output, active high reset logic, 140ms minimum reset timeout, -40°C to 85°C operating temperature range, SOT-143-4 package, and MSL 1 moisture sensitivity level. All listed substitute parts maintain these specifications.

Q: Are there differences in packaging formats among the substitute parts?

A: Yes. MAX812LEUS+T is available in Cut Tape (CT) and Digi-Reel® formats. STM812LW16F, ADM812LARTZ-REEL7, APX812-46UG-7, and MIC812LUY-TR are supplied in Tape & Reel (TR) format. Packaging selection should align with production assembly requirements and handling procedures.

Q: Do all substitute parts meet current compliance standards?

A: All substitute parts are ROHS3 compliant and REACH unaffected, addressing the RoHS non-compliance of the original MAX812LEUS-T. All parts carry EAR99 export classification and MSL 1 moisture sensitivity level.

Q: Which substitute part has the best inventory availability?

A: STM812LW16F from STMicroelectronics has the highest inventory availability at 36,300 units in stock, followed by MAX812LEUS+T at 5,645 units. Inventory levels should be verified with suppliers for current availability.

Q: Are there any functional differences between the Analog Devices and third-party substitute parts?

A: No functional differences exist among the listed substitute parts. All maintain identical electrical specifications for voltage threshold, output configuration, reset timing, and operating temperature range. Differences are limited to manufacturer, packaging format, and product status.
