| FFF Compatibility | The pinout (Pin 1: VDD/VS, Pin 2: VOUT/VO, Pin 3: GND) and package layout are identical to the LM50.Both parts are housed in a standard SOT-23-3 package with identical physical dimensions and footprint.The supply voltage range of the MCP9700A (2.3V to 5.5V) is narrower than the LM50 (4.5V to 10V). It cannot be used if the system supply exceeds 5.5V. | Maintains the exact same 3-pin assignment (Pin 1: VDD/VS, Pin 2: VOUT/VO, Pin 3: GND) on SOT-23-3.Both devices use a standard SOT-23-3 footprint, allowing assembly on the same PCB land pattern.The supply voltage is limited to 2.3V - 5.5V (vs 4.5V - 10V for the LM50), and accuracy is slightly lower (±4°C max at 25°C) than the A-grade variant. | ||
 AI Summary | LM50CIM3/NOPB by Texas Instruments: Temperature Sensor Analog, Local -40°C ~ 125°C 10mV/°C SOT-23-3. | This is the premier active replacement option, offering the same 10mV/°C scale factor and SOT-23-3 pinout. It provides improved typical accuracy but is restricted to a maximum supply voltage of 5.5V.
| This is the standard accuracy grade version of the MCP9700 series. It offers a fully pin-compatible SOT-23-3 footprint and the same 10mV/°C slope, but with a wider accuracy tolerance and 5.5V supply voltage limit.

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 LM50CIM3/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 LM50CIM3/NOPB are the MCP9700AT-E/TT (Microchip Technology) and the MCP9700T-E/TT (Microchip Technology), 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 LM50CIM3/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 LM50CIM3/NOPB (Texas Instruments) is a part in the Temperature Sensors category. This page lists qualified, cross-referenced replacements for it with a side-by-side comparison.
