|---|---|---|---|---|
| FFF Compatibility | Exactly identical pinout, pin assignments, exposed pad connection (OUTPUT), and package package footprint (TO-263-3 / DDPAK).Identical package dimensions, mechanical envelope, and mounting type.Direct functional equivalent with identical electrical characteristics. | Pinout is functionally equivalent, but minor pin naming differences exist (ADJ/GND, OUTPUT, INPUT vs GND, VOUT, VIN) and package is designated as D2PAK/A.Standard TO-263-3 (D2PAK) package aligns perfectly with the original land pattern footprint.Meets or exceeds all original electrical requirements, providing 3.3V fixed output at 3A. | ||
 AI Summary | LT1085CM-3.3 by Analog Devices: Linear Voltage Regulator IC 1 Output 3A DDPAK-3. | This is the direct lead-free (Pb-free) successor of the queried part from the original manufacturer. It offers identical electrical specifications, pinout, and physical package, making it an absolute drop-in replacement with no design changes required. Use this part to directly transition from the obsolete lead-containing version to a RoHS-compliant active component.
| This is an active, highly reliable second-source alternative from STMicroelectronics in the same TO-263 physical package. It maintains the identical 3A output capability and 3.3V fixed output, but expands the operating input voltage limit to 30V and offers an industrial temperature range. It is an excellent cross-reference for high-reliability applications.

You searched one part. Parter watches your whole BOM.
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.
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.
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 LT1085CM-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.
The closest qualified second sources for the Analog Devices LT1085CM-3.3 are the LT1085CM-3.3#PBF (Analog Devices Inc.) and the LD1085D2M33R (STMicroelectronics), out of 4 matched alternatives in total. Each is compared against the original on fit, form and function in the table above.
Not always. The alternatives to the LT1085CM-3.3 are matched on function but can differ in package, pinout or a key parameter, so review the fit/form/function notes in the table and the datasheet before designing one in.
The LT1085CM-3.3 (Analog Devices) is a part in the Power Management (PMIC) category. This page lists qualified, cross-referenced replacements for it with a side-by-side comparison.
