AI Summary

LM5025AMTC/NOPB by Texas Instruments: Forward Converter Regulator Positive, Isolation Capable Output Step-Up/Step-Down DC-DC Controller IC 16-TSSOP.

This is the direct tape-and-reel variant of the obsolete tube-packaged LM5025AMTC/NOPB. It is 100% identical in silicon and packaging, and is currently active in production, making it the perfect immediate drop-in replacement.

  • 100% electrically and physically identical to the original part
  • Zero layout, schematic, or BOM modifications required
  • Active production status under the tape-and-reel ordering code

An active family variant featuring pin-compatibility. The soft-start capacitor must be resized to account for the increased charging current, and the higher maximum duty cycle (91% vs 80%) should be validated in the target application.

  • Pin-compatible drop-in footprint with zero PCB changes required
  • Increased VCC regulator current limit of 55 mA (vs 25 mA) provides additional gate drive headroom
  • Active, long-lived variant from the same manufacturer
  • Requires resizing the soft-start capacitor upward to maintain the same soft-start ramp time
  • Higher maximum duty cycle (91% vs 80%) may require circuit validation to prevent transformer saturation under transient conditions

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.
