|---|---|---|---|---|
| FFF Compatibility | Identical TO-252-3 package and pinout (Pin 1: ADJ/GND, Pin 2: OUT, Pin 3: IN, Tab: OUT).Standard TO-252 (DPAK) physical package matching original dimensions.Output is adjustable instead of fixed 1.5V, which requires adding two external resistors to configure the output voltage. | Uses a 5-pin TO-252-5 package with different pin layout instead of a 3-pin package.Same overall TO-252 (DPAK) body height and width, but has 5 pins instead of 3.Provides exact fixed 1.5V output and meets the 3A current rating with improved dropout voltage performance. | ||
 AI Summary | FAN1587AD15X by onsemi: - Converter, Intel Pentium® GTL+ Voltage Regulator IC 1 Output TO-252 (DPAK). | The AZ2185D-ADJTRG1 is an active, high-quality 3A LDO that provides a drop-in physical footprint match. It is adjustable rather than fixed at 1.5V, meaning two external feedback resistors must be added to the board layout to set the output voltage.
| The RP108J151D-T1-FE offers the exact fixed 1.5V output and 3A current rating needed, along with much lower dropout voltage. However, it requires a PCB redesign as it uses a 5-pin TO-252-5 package instead of the original 3-pin package.

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 onsemi FAN1587AD15X 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 onsemi FAN1587AD15X are the AZ2185D-ADJTRG1 (Diodes Incorporated) and the RP108J151D-T1-FE (Nisshinbo Micro Devices Inc.), out of 6 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 FAN1587AD15X 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 FAN1587AD15X (onsemi) is a part in the Power Management (PMIC) category. This page lists qualified, cross-referenced replacements for it with a side-by-side comparison.
