 AI Summary | LMP8640MKE-H/NOPB by Texas Instruments: Current Sense Amplifier 1 Circuit SOT-23-THIN. | This is the direct active sibling part within the same product family, where the only difference is the packaging format. The queried 'MKE' suffix refers to a small tape and reel (250 units), whereas the 'MKX' suffix represents a large tape and reel (3000 units), making it a perfect electrical and physical replacement.
| This is the high-voltage (HV) version of the same family. It is fully pin-compatible and functionally identical, but extends the maximum input common-mode voltage rating from 42 V to 76 V, offering an upgraded safety ceiling for rugged environments.

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 LMP8640MKE-H/NOPB 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 LMP8640MKE-H/NOPB are the LMP8640MKX-H/NOPB (Texas Instruments) and the LMP8640HVMKX-H/NOPB (Texas Instruments), 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 LMP8640MKE-H/NOPB 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 LMP8640MKE-H/NOPB (Texas Instruments) is a part in the Linear category. This page lists qualified, cross-referenced replacements for it with a side-by-side comparison.
