|---|---|---|---|---|
| FFF Compatibility | SOP-8 (DUB) package with identical pin assignments (TXD, RXD, VCC, and GND pins align perfectly).Same physical footprint and mounting dimensions, requiring zero PCB layout modifications.Meets or exceeds all electrical parameters of the ISO1050, supporting 1 Mbps data rates. | Pins 2 (TXD) and 3 (RXD) are swapped compared to the ISO1050, and the DWV footprint is slightly wider than the DUB package.SOP-8 (DUB) and SOIC-8 (DWV) are both 8-pin surface-mount devices but have minor package width differences.Meets and significantly exceeds the isolation, voltage, and data rate performance parameters of the ISO1050. | ||
 AI Summary | ISO1050DUB by Texas Instruments: 1/1 Transceiver, Isolated Half CANbus 8-SOP. | The NSI1050-DDBR is a direct second-source drop-in replacement that retains the identical SOP-8 (DUB) package and pinout, eliminating any need for PCB modification. It provides an active-lifecycle alternative with improved CMTI of 80 kV/µs and an extended industrial temperature range up to 125°C.
| The ISO1042BDWVR is Texas Instruments' modern 8-pin isolated CAN transceiver replacement. While it offers vastly superior bus fault protection (70V) and CAN FD capability, it requires a minor PCB trace change due to swapped TXD and RXD pins.

You searched one part. Parter watches your whole BOM.
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.
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.
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 Texas Instruments ISO1050DUB 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.
The closest qualified second sources for the Texas Instruments ISO1050DUB are the NSI1050-DDBR (NOVOSENSE) and the ISO1042BDWVR (Texas Instruments), out of 5 matched alternatives in total. Each is compared against the original on fit, form and function in the table above.
Not always. The alternatives to the ISO1050DUB are matched on function but can differ in package, pinout or a key parameter, so review the fit/form/function notes in the table and the datasheet before designing one in.
The ISO1050DUB (Texas Instruments) is a part in the Interface category. This page lists qualified, cross-referenced replacements for it with a side-by-side comparison.
