Substitute Part Grouping Explanation
Substitution of the APX810-46SAG-7 is determined by strict equivalence across the following critical parameters:
Mandatory Matching Parameters:
- Voltage threshold: 4.63V (±tolerance)
- Output configuration: Push-Pull, Totem Pole
- Reset logic: Active High
- Number of voltages monitored: 1
- Package / Case: TO-236-3, SC-59, SOT-23-3 (mechanical compatibility)
- Mounting type: Surface Mount
- Reset timeout: 140ms minimum or equivalent
Allowable Variations:
- Operating temperature range: Extended ranges (-40°C ~ 125°C) are acceptable as they encompass the original -40°C ~ 85°C specification
- Manufacturer: Different manufacturers acceptable if electrical parameters match
- Product status: Active product status preferred over "Not For New Designs"
- Packaging format: Tape & Reel (TR) or Cut Tape (CT) & Digi-Reel® acceptable for same electrical device
Non-Substitutable Parameters:
- Voltage threshold deviation beyond tolerance
- Different output configuration or reset logic
- Different package type (e.g., SC-70 vs SOT-23-3 requires PCB redesign)
Substitute parts are grouped into three categories: Direct Diodes Incorporated equivalents with extended temperature capability, manufacturer-recommended alternatives from Analog Devices Inc./Maxim Integrated, and cross-manufacturer equivalents from Microchip Technology.

Engineering Selection Recommendations
Primary Recommendation: APX810S-46SA-7
The APX810S-46SA-7 from Diodes Incorporated is the direct successor to the APX810-46SAG-7. It maintains identical electrical specifications (4.63V threshold, 140ms reset timeout, push-pull totem pole output) while offering extended operating temperature range (-40°C ~ 125°C) and active product status. This part requires no design changes and provides the highest compatibility with existing PCB layouts and schematics. ROHS3 compliance and REACH unaffected status are maintained.
Secondary Recommendation: ADM810LARTZ-REEL or ADM810LARTZ-REEL7
Analog Devices Inc. ADM810 series parts provide full electrical equivalence with extended temperature range (-40°C ~ 125°C). Both variants maintain 4.63V threshold, 140ms reset timeout, and SOT-23-3 packaging. The ADM810LARTZ-REEL7 variant offers significantly higher inventory availability (24,821 pcs vs 1,779 pcs). Both are ROHS3 compliant and REACH unaffected.
Alternative Recommendation: MAX810LEUR+T or MAX810LEUR+T10
Maxim Integrated MAX810 series maintains the 140ms reset timeout specification and 4.63V threshold with SOT-23-3 packaging. Operating temperature range extends to -40°C ~ 105°C. Both variants are ROHS3 compliant and REACH unaffected. These parts are suitable where the extended temperature capability of ADM810 or APX810S-46SA-7 is not required.
Package Consideration: TCM810LVLB713
The TCM810LVLB713 from Microchip Technology provides electrical equivalence but uses SC-70-3 packaging instead of SOT-23-3. This part requires PCB redesign and is not recommended as a direct substitute without layout modification. Selection of this part is appropriate only when SC-70-3 footprint is already present in the design.
Not Recommended: MAX6347UR46+T and MAX6800UR46D3+T
These Maxim Integrated parts feature reduced reset timeout (100ms minimum vs 140ms minimum), which may not satisfy timing-critical applications. Selection requires verification that the shorter timeout meets system requirements.
Frequently Asked Questions (FAQ)
Q: Can I use APX810-46SRG-7 as a direct replacement for APX810-46SAG-7?
A: APX810-46SRG-7 uses SOT23R packaging instead of standard SOT-23-3. While electrically equivalent, the different package footprint requires PCB modification. Use only if your design already incorporates SOT23R footprint.
Q: What is the difference between ADM810LARTZ-REEL and ADM810LARTZ-REEL7?
A: Both parts are electrically identical with 4.63V threshold, 140ms reset timeout, and -40°C ~ 125°C operating range in SOT-23-3 packaging. The primary difference is inventory availability, with REEL7 offering significantly higher stock levels (24,821 pcs vs 1,779 pcs).
Q: Why do MAX6347UR46+T and MAX6800UR46D3+T show 100ms reset timeout instead of 140ms?
A: These Maxim Integrated variants feature different internal timing circuits resulting in 100ms minimum reset timeout. They are electrically compatible but may not satisfy applications requiring the full 140ms timeout specification. Verify system timing requirements before selection.
Q: Is TCM810LVLB713 a suitable substitute?
A: TCM810LVLB713 maintains all electrical parameters (4.63V threshold, 140ms timeout, active high reset) but uses SC-70-3 packaging instead of SOT-23-3. Direct substitution requires PCB redesign. Use only if SC-70-3 footprint is already present in your design.
Q: Are all substitute parts ROHS3 compliant and REACH unaffected?
A: Yes. All listed substitute parts maintain ROHS3 compliance and REACH unaffected status, matching the original APX810-46SAG-7 regulatory classification.
Q: What is the temperature range difference between APX810-46SAG-7 and APX810S-46SA-7?
A: APX810-46SAG-7 operates -40°C ~ 85°C, while APX810S-46SA-7 extends to -40°C ~ 125°C. The extended range of APX810S-46SA-7 encompasses the original specification, making it suitable for applications requiring higher temperature operation without design modification.
Q: Can I substitute based on voltage threshold alone?
A: No. Voltage threshold is one of several critical parameters. Output configuration (push-pull totem pole), reset logic (active high), reset timeout (140ms minimum), and package type (SOT-23-3) must all match or be compatible. Mismatches in any parameter may cause circuit malfunction.
Q: What does "Not For New Designs" mean for APX810-46SAG-7?
A: This designation indicates the part is in mature/end-of-life status and Diodes Incorporated does not recommend it for new product development. Existing designs may continue using available inventory, but new designs should select from active product alternatives such as APX810S-46SA-7 or cross-manufacturer equivalents.
