| FFF Compatibility | The pinout is identical (Pin 1: ADJ, Pin 2: OUT/Tab, Pin 3: IN) and mounts directly to the original land pattern.Standard TO-252 (DPAK) surface-mount package matching the original dimensions.Exceeds the original specifications in current and input voltage. Operating temperature (0°C to 125°C) is narrower than original (-40°C to 125°C), but serves standard commercial and industrial environments. | Standard TO-252 adjustable regulator pinout (Pin 1: ADJ, Pin 2: OUT, Pin 3: IN).Identical TO-252 outline matching the original physical package dimensions.Maximum input voltage is 15V (lower than the original 18V). Operating temperature range (-20°C to 125°C) is slightly narrower than the original (-40°C to 125°C). | ||
 AI Summary | FAN1616ADX by onsemi: Linear Voltage Regulator IC Positive Adjustable 1 Output 500mA TO-252 (DPAK). | The NCP1117DTARKG is a highly robust replacement that exceeds the original part's input voltage rating (20V vs 18V) and output current limit (1A vs 500mA). It uses the identical standard TO-252 pin layout.
| The AZ1117CD-ADJTRG1 is an active, widely available 1A LDO regulator. It serves as an excellent drop-in replacement provided that the actual application's operating input voltage does not exceed 15V.

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 FAN1616ADX 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 FAN1616ADX are the NCP1117DTARKG (onsemi) and the AZ1117CD-ADJTRG1 (Diodes Incorporated), out of 5 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 FAN1616ADX 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 FAN1616ADX (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.
