| FFF Compatibility | Both parts share the exact same 8-VSSOP (DGK) package and identical pin assignments.Both use the 8-VSSOP package (3.00mm x 3.00mm) with standard mounting specifications.Identical electrical specifications, including the 50 V/V gain version (A2). | The pin assignment is different: Pin 3 is CMPIN (comparator input) and Pin 6 is CMPOUT (comparator output) instead of LIMIT and ALERT.Housed in the identical 8-VSSOP package footprint.Features the same 50 V/V gain version (A2) and meets or exceeds all other electrical parameters. | ||
 AI Summary | INA301A2IDGKT by Texas Instruments: Current Monitor Regulator High/Low-Side 8-VSSOP. | This is the exact same silicon variant of the queried device, but supplied in a large tape and reel format (2500 units) instead of the small tape and reel format (250 units). It is a perfect, active, direct drop-in replacement.
| The INA310 is TI's newer-generation, high-performance upgrade. It operates up to 110 V and offers 1.3 MHz bandwidth, but requires a minor redesign to feed the comparator's input with a voltage divider rather than setting an external limit voltage.

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 INA301A2IDGKT 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 INA301A2IDGKT are the INA301A2IDGKR (Texas Instruments) and the INA310A2IDGKR (Texas Instruments), 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 INA301A2IDGKT 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 INA301A2IDGKT (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.
