FFF CompatibilityFeatures the exact same 8-pin SOIC layout, including identical pin functions (OUT, SENSE, GND, SHDN, IN).Housed in the identical 8-SOIC package size (3.90mm width).Meets or exceeds all electrical parameters of the target, including 1.5A output current and 20V maximum input voltage, while upgrading capacitor compatibility.Shares the exact pin assignment of the original lead-based non-A LT1963ES8-3.3.Maintains the same 8-SOIC package shape and dimensions.Functions identically with the same 1.5A output, 20V input limit, and transient response.
AI Summary

LT1963ES8-3.3 by Analog Devices: Linear Voltage Regulator IC 1 Output 1.5A 8-SO.

This is the direct modern upgrade of the obsolete LT1963ES8-3.3 in the same footprint. The 'A' version introduces improved stability, allowing the regulator to be used with low-ESR ceramic output capacitors.

  • Direct modern upgrade of the obsolete target regulator
  • Fully pin-compatible drop-in replacement with identical 8-SOIC footprint
  • Upgraded stability allows the use of very low-ESR ceramic output capacitors (10µF min)
  • Requires minimum 10µF ceramic capacitor for stable operation if transitioning from older tantalum or electrolytic setups.

This is the direct lead-free (RoHS compliant) transition variant of the original obsolete part. It is completely identical in performance, including the restriction on using ceramic capacitors without a series resistor.

  • Direct lead-free RoHS-compliant equivalent to the obsolete part
  • Identical silicon performance and same capacitor limitations as the original target
  • No PCB modification or redesign required
  • Shares the original non-A design limitations, meaning it is not stable with very low-ESR ceramic capacitors without series resistance.

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 Analog Devices LT1963ES8-3.3 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.
