AI Summary

MC74ACT20D by onsemi: NAND Gate IC 2 Channel 14-SOIC.

The MC74ACT20DG is the direct, Pb-free (RoHS-compliant) equivalent to the obsolete MC74ACT20D. Since it is produced by the same manufacturer, it guarantees complete mechanical and electrical drop-in compatibility. This is the highest-confidence replacement option.

  • Direct manufacturer-recommended Pb-free replacement for the obsolete MC74ACT20D
  • Identical electrical characteristics and performance specs
  • Supplied in the same Tube/Rail packaging (55 units per rail)

The MC74ACT20DR2G is functionally and physically identical to the MC74ACT20DG but is supplied in Tape & Reel packaging (2500 units) rather than Tube packaging. It is an excellent drop-in option if Tape & Reel is preferred or acceptable for assembly.

  • Identical electrical and mechanical characteristics to the queried part
  • Active lifecycle status with high availability
  • Supplied in Tape & Reel packaging rather than the original Tube/Rail packaging

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 MC74ACT20D 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.
