FFF CompatibilityPinout assignment is identical to the target part across all 9 pins.The 9-VSON package matches the physical dimensions and land pattern of the original 9-DFN (3x3) package.The device features TTL-compatible inputs and meets or exceeds all voltage, current, and speed specifications of the original part.The pinout assignments are identical to the target part across all 9 pins (including the NC pin and the exposed thermal pad).Both parts share the exact same 9 Ld 3x3 DFN package and physical dimensions.The alternative meets or exceeds all electrical parameters, providing compatible 3.3V/TTL logic inputs, a wider operating voltage, and higher peak current capability.
AI Summary

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

This Texas Instruments part is an excellent cross-brand drop-in alternative. It features an identical 9-pin assignment, matching 3x3mm footprint, and TTL-compatible thresholds, while offering improved peak gate drive capability (3A) and an increased maximum bootstrap voltage (120V).

  • Highly reliable alternative from Texas Instruments
  • Higher peak output drive current (3A vs 1.25A) allowing for driving larger MOSFETs
  • Higher maximum bootstrap voltage (120V vs 100V)

This active part is a direct drop-in sibling within the Renesas high-frequency driver family. It provides identical physical footprints, pin assignments, and TTL-compatible thresholds while upgrading the peak drive current to 2A and boot voltage tolerance to 114V.

  • Direct drop-in sibling from the same manufacturer family
  • Higher peak output drive current (2A vs 1.25A) for faster switching
  • Higher maximum bootstrap voltage (114V vs 100V)

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.
