AI Summary

MC14538BDWR2 by onsemi: Monostable Multivibrator 3-18V Dual Precision.

This is the direct Pb-free/RoHS-compliant drop-in replacement from onsemi. It uses the exact same SOIC-16 Wide package and is fully backward-compatible with the obsolete MC14538BDWR2 in all electrical and physical parameters.

  • Direct active Pb-free/RoHS replacement from the original manufacturer
  • Exact same physical SOIC-16 Wide package dimensions and land pattern
  • Identical electrical parameters (3V to 18V supply range) and timing characteristics

This is the automotive-grade version of the direct Pb-free replacement. It offers identical pinout and physical dimensions but is manufactured to meet rigorous AEC-Q100 and PPAP standards, ensuring higher reliability.

  • AEC-Q100 qualified and PPAP capable for automotive reliability standards
  • Exact physical drop-in equivalent in SOIC-16 Wide package
  • Identical functional performance and timing ranges
  • Slightly higher unit cost due to automotive qualification testing

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.

Frequently asked questions

Yes. The onsemi MC14538BDWR2 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.
