AI Summary

MT52B103F3950F01000 by STE: 10kΩ 3950K ±1% Through Hole NTC Thermistors RoHS.

The Eaton NRL2104F3950B1F is a direct drop-in alternative with matching electrical parameters and package dimensions. It provides a nominal resistance of 10 kΩ at 25°C, a B25/50 value of 3950K, and ±1% tolerance across both resistance and B-value. Operating across -40°C to +125°C, it serves as an ideal replacement for the MT52B103F3950F01000.

  • Pin-compatible and direct drop-in replacement with identical 2-pin radial leaded epoxy bead package
  • Identical nominal resistance of 10 kΩ at 25°C and matching Beta value of 3950K (25/50°C)
  • Identical ±1% resistance tolerance and ±1% B-value tolerance

The TDK B57861S0103F040 is a high-reliability, AEC-Q200 qualified NTC thermistor in a leaded bead package with a 10 kΩ nominal resistance and ±1% tolerance. It offers an expanded operating temperature range up to +155°C. Due to its B25/100 value of 3988K, minor adjustment to temperature lookup tables or equations may be needed.

  • Identical nominal resistance of 10 kΩ at 25°C
  • Higher temperature capability (-55°C to +155°C vs -40°C to +125°C)
  • AEC-Q200 qualified for high-reliability automotive and industrial environments
  • Different Beta value parameter (B25/100=3988K vs B25/50=3950K), requiring software curve calibration

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.
