FFF CompatibilityThe 8-SOIC package has a completely different land pattern and pin count compared to the 9-DFN 3x3 package.The 8-SOIC package is physically larger and has leads, whereas the original is a leadless 9-DFN 3x3 package.It is the same internal gate driver design and matches all electrical specifications exactly.Uses the identical 9-DFN 3x3 package with the exact same 9-pin assignments and thermal pad.Matches the exact physical dimensions and package type.Configured for fixed CMOS logic thresholds (3.7V/7.4V) rather than the original TTL logic levels (1.4V/2.2V).
AI Summary

ISL89401AR3Z by Renesas Electronics Corporation: Half-Bridge Gate Driver IC Non-Inverting 9-DFN (3x3).

This is the 8-pin SOIC sibling of the original series, sharing the identical internal silicon and TTL-compatible logic thresholds. While it requires a package redesign, it is functionally a drop-in match.

  • Functionally identical die to the original obsolete part
  • Preserves the same 1.25A peak source/sink current and 100V high-side rating
  • Utilizes the exact same 3.3V/TTL logic input thresholds (1.4V/2.2V)
  • Requires PCB layout redesign due to package change from DFN-9 to SOIC-8
  • Takes up significantly more board space (approx. 4.9mm x 3.9mm vs 3mm x 3mm)

This is the CMOS logic threshold version from the same family in the identical 9-DFN package. While it fits the exact same board footprint, its high logic thresholds (3.7V VIL, 7.4V VIH) are different and it is also obsolete.

  • Drop-in footprint and pin compatibility with the original part
  • Same physical 9-DFN 3x3 footprint size and thermal pad layout
  • Identical 100V high-side capability and 1.25A drive current
  • Also obsolete, so it is only suitable as a short-term sourcing alternative
  • Higher logic thresholds may be incompatible with low-voltage logic/microcontrollers (e.g., 3.3V)

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.

Frequently asked questions

Yes. The Renesas Electronics Corporation ISL89401AR3Z is marked obsolete, so the manufacturer has discontinued it and any remaining supply is limited to distributor stock. The qualified second sources on this page are active parts you can design in today.
