AI Summary

MTB10103F3950F00 by STE: 10kΩ 3950K ±1% Through Hole,P=1.8mm NTC Thermistors RoHS.

NTCLE100E3103JB0 is a widely available radial epoxy-coated NTC thermistor from Vishay with a 10 kΩ base resistance and 3977 K B-value. It is suitable for applications where strict enamel wire dimensions are not mandatory.

  • Established industry-standard NTC thermistor series with high dissipation capability (500 mW max)
  • Matching 10 kΩ R25 nominal resistance with near-identical B25/85 value (3977 K vs 3950 K)
  • Identical operating temperature range (-40°C to +125°C)
  • Wider resistance tolerance (±5% vs ±1%)
  • Slightly different B-value (3977 K vs 3950 K)

B57861S0103F040 is a high-reliability automotive-qualified NTC thermistor from TDK featuring a 10 kΩ R25 value with ±1% accuracy. While its B-value (3988 K vs 3950 K) and rigid lead wire construction differ slightly from enameled wire, it is a robust alternative for temperature measurement applications.

  • High reliability AEC-Q200 qualified automotive-grade NTC thermistor from TDK
  • Matching 10 kΩ R25 base resistance with ±1% tolerance
  • Extended upper operating temperature range up to +155°C (vs +125°C target)
  • Different lead wire material (standard tinned leads vs enameled thin wire)
  • Slightly higher B-value (3988 K vs 3950 K) requiring ADC lookup table adjustment for high-accuracy systems

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.
