FFF CompatibilityRequires external resistor dividers to set the specific 4.63V and 2.93V thresholds on the adjustable inputs. Pin assignments differ from the original.Shares the identical SOT-23-6 footprint.Can monitor both VCC1 and VCC2 rails simultaneously and provides dual independent active-low push-pull outputs.Pin 5 is WDI (watchdog input) instead of RST2, and Pin 1 is RST (referenced to VCC2) instead of RST1.Identical SOT-23-6 package size and layout.Provides only a single reset output (referenced to VCC2) and adds a watchdog timer instead of providing dual independent reset outputs.
AI Summary

MAX6351LSUT+T by Analog Devices: Supervisor Push-Pull, Totem Pole 2 Channel SOT-23-6.

An active, high-reliability dual-channel supervisor from Texas Instruments. It features dual independent push-pull active-low outputs that can serve as equivalents to RST1 and RST2, but uses adjustable threshold inputs that require external resistor dividers.

  • Active product lifecycle from a highly reliable manufacturer
  • Wider operating temperature range (-40°C to +125°C TJ vs -40°C to +85°C TA)
  • Maintains identical SOT-23-6 package footprint
  • Requires 4 external resistors to program the 4.63V and 2.93V thresholds
  • Lacks a dedicated manual-reset (MR) input

Recommended by the manufacturer as a close alternative in the same series with identical factory-trimmed thresholds. It has a single push-pull reset output referenced to VCC2 (equivalent to RST2 on the original) and replaces RST1 with a watchdog timer.

  • Official parametric substitute recommended by the manufacturer
  • Maintains identical SOT-23-6 footprint
  • Monitors identical factory-trimmed 4.63V and 2.93V thresholds
  • Lacks the first independent reset output (RST1) referenced to VCC1
  • Adds watchdog timer functionality on Pin 5 which must be handled in design

You searched one part. Parter watches your whole BOM.

  1. All your BOM, at once

    Parter maps every line to live stock, lead time, lifecycle and compliance data across the entire market — not part by part.

  2. Hear about problems before they hit production

    Allocation, EOL and last-time-buy notices surface the moment they appear, not when your buyer's PO bounces.

  3. Qualified replacements in minutes, not days

    Every at-risk line gets form-fit-function matches like the ones above — deltas flagged, evidence attached. Review, push to your BOM, and Parter starts watching the new part too.
