| FFF Compatibility | The physical 8-DIP footprint and pinout assignments are identical to the original onsemi HCPL-2631 part.Standard 8-DIP (0.300", 7.62mm) physical package dimensions and mounting are identical.Maintains the 10 MBd data rate, 5V supply voltage, and 50 mA channel output current rating. | The pinout assignments and package dimensions match the original part exactly.Supplied in an identical 8-DIP through-hole package.While speed, supply voltage, and temperature range are equivalent or superior, the output current rating is lower at 25 mA per channel vs 50 mA. | ||
HCPL-2631 by onsemi: Logic Output Optoisolator 10Mbps Open Collector 2500Vrms 2 Channel 5kV/µs CMTI 8-DIP. | The Broadcom HCPL-2631-000E is the direct RoHS-compliant counterpart to the original obsolete onsemi part, offering identical package, pinout, and key electrical specs alongside improved isolation voltage.
| As the official direct replacement recommended by onsemi, the HCPL2631M is highly compatible and features superior isolation and temperature ratings, though it reduces maximum output current per channel from 50 mA to 25 mA.

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 onsemi HCPL-2631 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 onsemi HCPL-2631 are the HCPL-2631-000E (Broadcom Limited) and the HCPL2631M (onsemi), out of 4 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 HCPL-2631 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 HCPL-2631 (onsemi) is a part in the Optocouplers, Optoisolators category. This page lists qualified, cross-referenced replacements for it with a side-by-side comparison.
