MAX809SEUR Overview
What changes between part numbers, and what to check before you lock the BOM — Supervisors.
MAX809SEUR is a Analog Devices order-code family — not a single orderable MPN. This page lists 2 variants that share the same core device but differ in suffix fields (package, grade, reel/tube, electrical bin, etc.). Pick the exact full part number; substituting within the family without checking the datasheet often causes assembly or spec mismatches.
IC MPU SPRVSR CIRC 2.93V SOT23-3 Other listed variants describe: Package: TO-236-3, SC-59, SOT-23-3 | Mounting Type: Surface Mount | Operating Temperature: -40°C ~ 105°C (TA) | Type: Simple Reset/Power-On Reset | Supplier Device Package: SOT-23-3 | Output: Push-Pull, Totem Pole.
Across listed variants, watch these parameters: packages: TO-236-3, SC-59, SOT-23-3.
Example MPNs: MAX809SEUR, MAX809SEUR+T.
Key Features
- Footprint / package: TO-236-3, SC-59, SOT-23-3Single package option across listed variants; still confirm reel vs tube suffix if you auto-insert.
- Lifecycle mix: ActiveConfirm lifecycle on the exact MPN, not just the base number prefix.
Target Applications
- Supervisors — design-in and field replacement
- BOM scrub where only the base prefix is known but suffix is TBD
- Second-source checks when the original MPN is constrained
Ordering Variants
Compare 2 MAX809SEUR part numbers by package, electrical parameters, lifecycle, and availability. Use RFQ for stock and lead-time confirmation.

Ordering Code Differences
How suffixes on MAX809SEUR map to package, grade, and reel options.
MAX809SEUR uses a shared prefix; characters after the prefix encode orderable options. Two lines with the same prefix are not drop-in replacements unless the differing columns match your need.
Suffixes seen here: +T.
Full MPN examples: MAX809SEUR+T.
Tip: photograph or copy the reel label — reel diameter, QTY per reel, and moisture sensitivity level (MSL) are often suffix-driven and won't show in the schematic.
How to Choose the Right MAX809SEUR Supervisors
Match the footprint first
Packages here: TO-236-3, SC-59, SOT-23-3. Open the land-pattern drawing before you substitute a different suffix.
Electrical headroom
Compare voltage and current columns in the variant table. For MAX809SEUR, a suffix with lower voltage or current rating will not survive the same circuit without recalculation.
Temp grade letter matters
Commercial (0–70 °C) and industrial (−40–85 °C+) suffixes look similar in the prefix — confirm ambient + self-heating, not just the first page of the datasheet.
Copy the full MPN
Do not BOM only "MAX809SEUR" — include the full suffix (e.g. +T). RFQ with reel/tube preference and required date code.
