| FFF Compatibility | Both parts share the identical SOT-23-3 (DBZ) package footprint and pin assignment: Pin 1 = IN, Pin 2 = OUT, Pin 3 = GND.The physical dimensions and package package body details of both parts are identical.Both are 2.5V series voltage references. The replacement operates over the same -40°C to 125°C temperature range with improved accuracy and lower drift, though it has a lower maximum output current capacity (5 mA vs 25 mA). | Both parts share the identical 3-pin SOT-23 package and pin assignment: Pin 1 = VIN, Pin 2 = VOUT, Pin 3 = GND.Both use standard 3-lead SOT-23 packages with identical physical layout and mounting profiles.Both operate as 2.5V series voltage references over a -40°C to 125°C temperature range with ±0.2% initial accuracy. The ISL21010 matches the original 25 mA current drive capability. | ||
 AI Summary | REF3025AIDBZR by Texas Instruments: Series Voltage Reference IC Fixed 2.5V V ±0.2% 25 mA SOT-23-3. | The REF3325AIDBZR is an active, modern series voltage reference from Texas Instruments that serves as an excellent upgrade to the obsolete REF3025. It is physically identical and offers substantial power savings and better thermal stability. It is highly recommended if your load current does not exceed 5 mA.
| The ISL21010CFH325Z-TK is an active 2.5V series reference from Renesas that matches both the ±0.2% initial accuracy and the full 25 mA output current capacity of the original REF3025. It represents the best second-source option if high current sourcing is required.

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 Texas Instruments REF3025AIDBZR 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 Texas Instruments REF3025AIDBZR are the REF3325AIDBZR (Texas Instruments) and the ISL21010CFH325Z-TK (Renesas Electronics Corporation), 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 REF3025AIDBZR 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 REF3025AIDBZR (Texas Instruments) is a part in the Power Management (PMIC) category. This page lists qualified, cross-referenced replacements for it with a side-by-side comparison.
