FFF CompatibilityTXD and RXD pins (Pins 2 and 3) are swapped compared to the ISO1050.SOIC-8 (DWV) package width is slightly different from the wider SOP-8 (DUB) package.Provides fully compatible and upgraded isolated CAN transceiver functions.
AI Summary

ISO1050DUBR by Texas Instruments: 1/1 Transceiver, Isolated Half CANbus 8-SOP.

This is Texas Instruments' recommended modern upgrade. While it offers superior fault protection and CAN FD capability, it requires a minor PCB trace modification because the TXD and RXD pins are swapped, and the package footprint is slightly narrower.

  • Upgraded performance with support for CAN FD up to 5 Mbps.
  • Vastly superior bus fault protection of ±70V (vs -27V to 40V on original).
  • Significantly higher Common-Mode Transient Immunity (CMTI) of 100 kV/µs.
  • Pins 2 (TXD) and 3 (RXD) are reversed, requiring PCB redesign.
  • Footprint is slightly narrower, requiring land pattern adjustment.

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.
