AZ810NSTR-G1 Equivalent & Substitute Parts

Part Overview

The AZ810NSTR-G1 is a single-channel power management supervisor IC manufactured by Diodes Incorporated, designed for reset and power-on reset applications. This component operates as a push-pull, totem pole output supervisor with active high reset functionality. The part is currently classified as obsolete, which necessitates identification of equivalent and substitute components for ongoing design requirements and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the AZ810NSTR-G1 is determined by strict equivalence across the following critical parameters:

• Voltage Threshold: 2.93V (single-channel monitoring requirement)
• Output Configuration: Push-Pull, Totem Pole topology
• Reset Logic: Active High operation
• Reset Timeout: 140ms Minimum
• Package: SOT-23-3 (TO-236-3, SC-59)
• Mounting Type: Surface Mount
• Functional Type: Simple Reset/Power-On Reset supervisor

Two substitute parts meet these criteria:

APX810S-29SAG7 (Diodes Incorporated) - MFR Recommended substitute with active product status and improved moisture sensitivity rating.

MAX810SEUR+T (Analog Devices Inc./Maxim Integrated) - Parametric equivalent with active product status and superior moisture sensitivity performance.

Parameter Comparison

Engineering Selection Recommendations

APX810S-29SAG7 is the manufacturer-recommended substitute from Diodes Incorporated. This part maintains active product status and provides improved moisture sensitivity performance (MSL 1 vs. MSL 3), supporting extended storage and handling flexibility. The extended operating temperature range (-40°C ~ 125°C) provides additional thermal margin for demanding applications.

MAX810SEUR+T is a parametric equivalent from Analog Devices Inc./Maxim Integrated. This part delivers identical functional and electrical characteristics with active product status and superior moisture sensitivity (MSL 1). The part is available in Cut Tape and Digi-Reel packaging formats, supporting both prototype and production volume requirements.

Both substitutes are ROHS3 compliant and REACH unaffected, maintaining regulatory alignment with the original component.

Frequently Asked Questions (FAQ)

Q: Can APX810S-29SAG7 and MAX810SEUR+T be used interchangeably with AZ810NSTR-G1?

A: Both parts meet the electrical and mechanical substitution criteria. They share identical voltage threshold (2.93V), output configuration (push-pull, totem pole), reset logic (active high), reset timeout (140ms minimum), and package format (SOT-23-3). Direct PCB-level substitution is supported without circuit modification.

Q: What is the significance of the MSL rating difference?

A: The AZ810NSTR-G1 carries MSL 3 (168 hours maximum floor life), while both substitutes carry MSL 1 (unlimited floor life). MSL 1 components tolerate extended storage and handling without moisture absorption concerns, reducing production risk and enabling greater supply chain flexibility.

Q: Does the extended temperature range of APX810S-29SAG7 affect compatibility?

A: The APX810S-29SAG7 operating range (-40°C ~ 125°C) exceeds the original specification (-40°C ~ 105°C). This extended range provides additional thermal margin and does not create compatibility issues. Applications operating within the original temperature window remain fully supported.

Q: Are there package or pinout differences between these parts?

A: All three parts use identical SOT-23-3 packaging (TO-236-3, SC-59). Pinout and mechanical dimensions are equivalent, supporting direct PCB substitution without layout modification.

Q: Which substitute should be selected for new designs?

A: Both APX810S-29SAG7 and MAX810SEUR+T are suitable for new designs. Selection depends on supply chain preference, packaging format requirements (APX810S-29SAG7 for standard reels; MAX810SEUR+T for cut tape or Digi-Reel options), and manufacturer relationship considerations.
