APX812-26UG-7 Equivalent & Substitute Parts

Part Overview

The APX812-26UG-7 is a single-channel power supply supervisor IC manufactured by Diodes Incorporated, designed for reset and power-on reset applications in power management circuits. This Surface Mount device operates across the industrial temperature range of -40°C to 85°C and features push-pull, totem pole output configuration with active high reset logic. The part is currently in active production status with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Substitute parts are identified when equivalent electrical parameters and mechanical compatibility are maintained across the same functional category.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the APX812-26UG-7 are qualified based on strict equivalence of the following electrical and mechanical parameters:

• Single-channel voltage monitoring functionality
• Voltage threshold of 2.63V
• Push-pull, totem pole output configuration
• Active high reset logic
• 140ms minimum reset timeout
• Operating temperature range of -40°C to 85°C
• Surface mount technology with TO-253-4 / TO-253AA package compatibility
• SOT-143 or SOT-143-4 supplier device package designation
• Active product status with ROHS3 compliance and MSL 1 rating

The identified substitute parts maintain full functional and mechanical compatibility within these defined parameters.

Parameter Comparison

Engineering Selection Recommendations

All three parts—APX812-26UG-7, ADM812RARTZ-REEL7, and MAX812REUS+T—are functionally equivalent for single-channel voltage monitoring and reset applications. Selection between these parts is based on availability, supply chain considerations, and manufacturer preference:

• APX812-26UG-7 (Diodes Incorporated): 3,300 units in stock
• ADM812RARTZ-REEL7 (Analog Devices): 1,700 units in stock
• MAX812REUS+T (Analog Devices/Maxim): 6,900 units in stock

All parts maintain active product status, ROHS3 compliance, and identical electrical specifications. The supplier device package designation differs slightly (SOT-143 versus SOT-143-4), but both are compatible with the TO-253-4 and TO-253AA mechanical footprints. No additional testing or verification is required for direct substitution when electrical and mechanical parameters are matched as specified.

Frequently Asked Questions (FAQ)

Q: Can ADM812RARTZ-REEL7 directly replace APX812-26UG-7 in existing designs?

A: Yes. Both parts share identical electrical parameters including 2.63V threshold, push-pull totem pole output, active high reset logic, and 140ms minimum reset timeout. The mechanical package compatibility (TO-253-4, TO-253AA) and surface mount technology are equivalent. The SOT-143-4 designation for the ADM812RARTZ-REEL7 is compatible with the SOT-143 footprint of the APX812-26UG-7.

Q: What is the difference between SOT-143 and SOT-143-4 package designations?

A: Both designations refer to the same physical package form factor with four leads. The "-4" suffix in SOT-143-4 explicitly indicates the four-lead configuration. Both are compatible with TO-253-4 and TO-253AA mechanical specifications and PCB footprints.

Q: Are all three parts suitable for industrial temperature applications?

A: Yes. All three parts operate across the -40°C to 85°C temperature range, meeting industrial application requirements.

Q: Do these parts require different handling or storage procedures?

A: No. All three parts share identical Moisture Sensitivity Level (MSL 1) ratings, indicating unlimited shelf life under standard storage conditions. No differentiated handling procedures are required.

Q: Which substitute part offers the best availability?

A: MAX812REUS+T currently has the highest inventory level at 6,900 units in stock, followed by APX812-26UG-7 at 3,300 units, and ADM812RARTZ-REEL7 at 1,700 units.

Q: Are all parts ROHS3 compliant?

A: Yes. APX812-26UG-7, ADM812RARTZ-REEL7, and MAX812REUS+T are all ROHS3 compliant with REACH Unaffected status and EAR99 ECCN classification.
