AI Summary

LM45CIM3 by Texas Instruments: Temperature Sensor Analog, Local -20°C ~ 100°C 10mV/°C SOT-23-3.

The alternative matches the source's 10 mV/°C gain and offers a wider temperature range, but it introduces a 500 mV DC offset at 0°C (compared to 0V for the source) and has a lower maximum operating supply voltage of 5.5V.

  • Pin-compatible drop-in replacement
  • Same temperature sensor gain of 10 mV/°C
  • Wider operating temperature range: -40°C to +125°C vs -20°C to +100°C
  • Different output voltage offset: 500 mV at 0°C vs 0 mV
  • Lower maximum operating voltage: 5.5V vs 10V

This alternative has the same 10 mV/°C gain and a wider temperature range but operates with a 500 mV output offset at 0°C (whereas the source has a 0V offset at 0°C). It also has a lower maximum operating supply voltage of 5.5V.

  • Pin-compatible drop-in replacement
  • Same temperature sensor gain of 10 mV/°C
  • Wider operating temperature range: -40°C to +125°C vs -20°C to +100°C

You searched one part. Parter watches your whole BOM.

  1. 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.

  2. 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.

  3. 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.
