|---|---|---|---|---|
| FFF Compatibility | The pinout and SOT-23-6 footprint are identical to the queried part, meaning no PCB modification is required.Housed in the identical 6-pin SOT-23-THIN physical package with the same mechanical dimensions.Provides the identical 100 V/V gain, 2.7 V to 12 V supply range, and -2 V to 42 V common-mode voltage range. | The SOT-23-6 package footprint matches, but Pin 5 is designated as VREF instead of NC. It must be connected to GND on the PCB for proper unidirectional operation.Fits the same SOT-23-6 footprint layout and physical dimensions.The supply voltage range is narrower (2.0 V to 5.5 V) compared to the original's 2.7 V to 12 V limit. | ||
 AI Summary | LMP8640MK-H/NOPB by Texas Instruments: Current Sense Amplifier 1 Circuit SOT-23-THIN. | This is the direct active equivalent from the same product series, differing only in the packaging delivery format (large tape & reel of 3000 units instead of the standard/small reel). It offers an immediate, risk-free drop-in replacement with identical electrical and physical characteristics.
| This is a high-precision, zero-drift alternative from Microchip featuring an exact gain of 100 V/V. It extends the input common-mode voltage capability up to 65 V, although it limits the maximum power supply voltage to 5.5 V. Pin 5 is used for VREF and must be tied to ground for matching unidirectional sensing.

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 LMP8640MK-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 LMP8640MK-H/NOPB are the LMP8640MKX-H/NOPB (Texas Instruments) and the MCP6C02T-100E/CHY (Microchip Technology), out of 3 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 LMP8640MK-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 LMP8640MK-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.
