MAX810MTR Equivalent & Substitute Parts

Part Overview

The MAX810MTR is a single-channel power management supervisor IC manufactured by onsemi, designed for reset and power-on reset applications in embedded systems. This device operates as a push-pull, totem pole output supervisor with a 4.38V voltage threshold and 140ms minimum reset timeout. The MAX810MTR is classified as obsolete, making equivalent and substitute parts necessary for ongoing production and maintenance applications. Active alternatives from multiple manufacturers provide functionally equivalent supervision capabilities with improved product status and compliance certifications.

Output configuration: Push-Pull, Totem Pole
Reset logic: Active High
Reset timeout: 140ms Minimum
Number of voltages monitored: 1 channel
Mounting type: Surface Mount

Package Compatibility Groups:

Substitutes are organized into two package families based on the allowed electrical and mechanical parameters:

Group 1: SOT-23-3 Package (TO-236-3, SC-59) Parts maintaining the original SOT-23-3 package footprint: ADM810MARTZ-REEL7, MAX810MEUR+T, MAX810MEUR+T10, MIC810MUY-TR, STM810MWX6F, TCM810MVNB713

Group 2: SC-70-3 Package (SOT-323) Parts with alternative SC-70-3 package: ADM810MAKSZ-REEL7, TCM810MVLB713

All substitute parts maintain identical electrical specifications (4.38V threshold, push-pull output, active high reset, 140ms timeout) and surface mount technology. Package selection depends on PCB layout requirements and available footprint space.

Engineering Selection Recommendations

All substitute parts listed maintain functional equivalence to the MAX810MTR across electrical specifications. Selection should prioritize the following factors:

Product Status: All substitute parts carry Active product status, eliminating obsolescence risk associated with the MAX810MTR. This ensures long-term availability and manufacturing support.

Compliance Certifications: All substitute parts are ROHS3 compliant, addressing regulatory requirements that the original MAX810MTR does not meet. All parts maintain REACH Unaffected status and EAR99 export classification.

Operating Temperature Range: Substitute parts from Analog Devices Inc. (ADM810MARTZ-REEL7, ADM810MAKSZ-REEL7, TCM810MVNB713, TCM810MVLB713) and Microchip Technology (TCM810MVNB713, TCM810MVLB713) support extended temperature operation to 125°C, compared to the MAX810MTR's 105°C maximum. Parts from Microchip Technology (MIC810MUY-TR) and STMicroelectronics (STM810MWX6F) operate to 85°C.

Package Selection: For PCB designs using SOT-23-3 footprints, select from ADM810MARTZ-REEL7, MAX810MEUR+T, MAX810MEUR+T10, MIC810MUY-TR, STM810MWX6F, or TCM810MVNB713. For SC-70-3 footprints, select ADM810MAKSZ-REEL7 or TCM810MVLB713.

Inventory Availability: MAX810MEUR+T offers the highest inventory level (15,237 pcs), followed by STM810MWX6F (4,200 pcs) and TCM810MVLB713 (3,605 pcs).

Frequently Asked Questions (FAQ)

Q: Can I use any substitute part as a direct replacement for MAX810MTR?

A: Yes, all listed substitute parts are electrically equivalent. However, package compatibility must be verified. SOT-23-3 package parts are pin-compatible with the original MAX810MTR footprint. SC-70-3 package parts require PCB redesign to accommodate the different package geometry.

Q: What is the difference between SOT-23-3 and SC-70-3 packages?

A: Both packages are three-pin surface mount devices with identical electrical functionality. SOT-23-3 (TO-236-3, SC-59) is larger and more commonly used in legacy designs. SC-70-3 (SOT-323) is a smaller package option. Pin assignments and electrical behavior are identical; only physical footprint differs.

Q: Why do some substitutes have different maximum operating temperatures?

A: Operating temperature ratings reflect manufacturer specifications and thermal design margins. Parts rated to 125°C (Analog Devices Inc., Microchip Technology) provide extended thermal headroom compared to 85°C-rated parts (Microchip Technology MIC810MUY-TR, STMicroelectronics STM810MWX6F). Selection depends on application thermal requirements.

Q: Are all substitute parts RoHS compliant?

A: Yes, all substitute parts are ROHS3 compliant. The original MAX810MTR is RoHS non-compliant. Substitution addresses regulatory compliance requirements for new production.

Q: What packaging options are available for high-volume procurement?

A: Substitute parts are available in Cut Tape (CT), Tape & Reel (TR), and Digi-Reel® packaging. Tape & Reel and Digi-Reel® options are preferred for automated assembly processes. Specific packaging availability varies by part number and supplier.

Q: Can I mix different substitute parts in the same production run?

A: Yes, all substitute parts maintain identical electrical specifications (4.38V threshold, push-pull output, active high reset, 140ms timeout). However, package consistency should be maintained within a single PCB design to avoid assembly complications.

Q: What is the reset timeout specification, and why is it important?

A: The 140ms minimum reset timeout defines the minimum duration the reset output remains asserted after power supply stabilization. This parameter is identical across all substitute parts and ensures consistent system initialization timing.
