MAX810STRG Equivalent & Substitute Parts

Part Overview

The MAX810STRG is a single-channel power management supervisor IC manufactured by onsemi, designed for reset and power-on reset applications. This device features push-pull totem pole output with a 2.93V voltage threshold and 140ms minimum reset timeout. The part is currently obsolete, making equivalent and substitute parts necessary for ongoing system support, maintenance, and new design implementations where the original component is no longer available through standard distribution channels.

Substitute Part Grouping Explanation

Substitution of the MAX810STRG is determined by strict equivalence across the following critical parameters:

Voltage threshold: 2.93V
Output configuration: Push-Pull, Totem Pole
Reset polarity: Active High
Reset timeout: 140ms Minimum
Number of monitored voltages: 1 Channel
Mounting type: Surface Mount
Package compatibility: SOT-23-3 (TO-236-3, SC-59)
Functional type: Simple Reset/Power-On Reset

Substitute parts are grouped into two categories: parametric equivalents (identical electrical and mechanical specifications) and similar parts (matching core functionality with package or temperature rating variations).

Engineering Selection Recommendations

For direct replacement of the obsolete MAX810STRG, select from active product status alternatives that maintain identical electrical specifications and SOT-23-3 package compatibility:

MAX810SEUR+T (Analog Devices Inc./Maxim Integrated) provides parametric equivalence with active product status and 1498 units in stock. Operating temperature range matches the original specification (-40°C ~ 105°C).

ADM810SARTZ-REEL7 (Analog Devices Inc.) offers the highest inventory availability (17170 units) with extended operating temperature range (-40°C ~ 125°C) and active product status. Tape & Reel packaging is suitable for production environments.

TCM810SVNB713 (Microchip Technology) provides 4936 units in stock with active product status, extended temperature range (-40°C ~ 125°C), and SOT-23-3 package compatibility.

MIC810SUY-TR (Microchip Technology) is available with 10310 units in stock and active product status. Operating temperature range is -40°C ~ 85°C, which is narrower than the original specification.

TCM810SVLB713 (Microchip Technology) uses SC-70-3 package instead of SOT-23-3. This part is suitable only for designs where package footprint can be modified to accommodate the smaller SC-70 form factor.

All substitute parts maintain ROHS3 compliance, MSL Level 1, and identical functional specifications for voltage threshold, output configuration, and reset characteristics.

Frequently Asked Questions (FAQ)

Q: Can MAX810SEUR+T directly replace MAX810STRG in existing designs?

A: Yes. MAX810SEUR+T maintains identical electrical specifications (2.93V threshold, push-pull totem pole output, active high reset, 140ms timeout) and SOT-23-3 package compatibility. Operating temperature range is equivalent (-40°C ~ 105°C).

Q: What is the difference between TCM810SVNB713 and TCM810SVLB713?

A: Both are Microchip Technology supervisor ICs with identical electrical specifications. TCM810SVNB713 uses SOT-23-3 package (direct replacement for MAX810STRG). TCM810SVLB713 uses SC-70-3 package, which is physically smaller and requires PCB layout modification.

Q: Why does ADM810SARTZ-REEL7 have a higher operating temperature range?

A: ADM810SARTZ-REEL7 is rated to -40°C ~ 125°C (TA), compared to MAX810STRG at -40°C ~ 105°C (TJ). This extended range does not affect compatibility; the part operates within the original specification range and provides additional margin for high-temperature applications.

Q: Is MIC810SUY-TR suitable for all MAX810STRG applications?

A: MIC810SUY-TR is electrically equivalent but has a narrower operating temperature range (-40°C ~ 85°C) compared to MAX810STRG (-40°C ~ 105°C). Use this part only in applications where the maximum operating temperature does not exceed 85°C.

Q: What packaging formats are available for substitutes?

A: MAX810SEUR+T is supplied in Cut Tape (CT) & Digi-Reel format. ADM810SARTZ-REEL7, MIC810SUY-TR, TCM810SVNB713, and TCM810SVLB713 are supplied in Tape & Reel (TR) format. All parts are surface mount with identical or compatible footprints except TCM810SVLB713 (SC-70-3 package).

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance and MSL Level 1 rating, matching the original MAX810STRG specifications.
