AI Summary

LM2991S/NOPB by Texas Instruments: Linear Voltage Regulator IC Negative Adjustable 1 Output 1A TO-263 (DDPAK-5).

LM2991SX/NOPB is the tape-and-reel packaging variation of the source part (which is supplied in tubes). It offers completely identical electrical, mechanical, and thermal specifications, making it a perfect drop-in alternative.

  • Identical electrical specifications and performance to the source part
  • Same physical DDPAK/TO-263 package and footprint
  • Supplied in Tape and Reel packaging, which is highly suitable for high-volume automated assembly

LM2991S is the leaded version of the source part. While it is electrically and physically identical in form factor and fit, it lacks RoHS compliance because it does not feature the lead-free (/NOPB) finish of the source.

  • Identical electrical specifications and performance to the source part
  • Same physical DDPAK/TO-263 package and footprint
  • Not RoHS compliant due to leaded terminal finish (contains Pb)

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.
