FFF CompatibilityThe part is a lead-free version in the exact same 8-pin SOIC (208 mil) package with identical pin assignments.Identical physical package, dimensions, and mounting style.Identical electrical performance, registers, and timing specs.Shares the identical 8-pin SOIC (208 mil) footprint and pinout assignments.Uses the same physical 8-pin SOIC package envelope.Although it performs the same digital temperature sensing and thermostat functions, software register maps, resolution differences (11-bit vs 9-bit), and control commands differ and will require host firmware modifications.
AI Summary

DS1620S by Analog Devices: Temperature Sensor Digital, Local -55°C ~ 125°C 9 b 8-SOIC.

This is the direct lead-free (RoHS-compliant) replacement for the DS1620S, offering identical specifications, pin assignments, and package dimensions. It can be populated on the existing board with zero changes to the PCB layout or firmware.

  • Direct RoHS-compliant lead-free drop-in replacement
  • Exactly identical pinout, package, and dimensions
  • Zero software or firmware changes required

This is a higher-precision alternative within the same family, sharing the identical 8-pin SOIC footprint and pinout. While physically a direct fit, it requires firmware modifications to accommodate its 11-bit resolution and updated register command set.

  • Same 8-pin SOIC (208 mil) package and identical pinout
  • Higher temperature measurement resolution (11-bit vs 9-bit)
  • Lower price point compared to original DS1620 series
  • Requires firmware adjustments due to different registers and resolution (11-bit vs 9-bit)

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.
