| FFF Compatibility | The 16-pin SOIC package has an identical pin-out layout, matching all signal, power, feedback/sense, and NC pins exactly.Both parts utilize the standard wide-body 16-SOIC (0.295 inch, 7.50mm width) physical package footprint.Offers equivalent precision amplification with 40 µV input offset voltage and supports up to ±18V dual supplies. | Matches the 16-pin SOIC pinout assignment exactly, including gain setting, inputs, supplies, output, and feedback.Both devices are packaged in the 16-SOIC (0.295 inch, 7.50mm width) surface-mount package.Features a JFET input stage, which dramatically reduces bias current but results in a higher input offset voltage (200 µV vs 25 µV) and a higher minimum supply voltage (±6V vs ±2.25V). | ||
 AI Summary | INA114AU by Texas Instruments: Instrumentation Amplifier 1 Circuit 16-SOIC. | The AMP02FSZ is an excellent second-source, pin-compatible alternative in the same 16-SOIC package, offering higher slew rate and bandwidth.
| The INA111AU provides a direct pin-compatible JFET-input alternative from the same manufacturer, ideal for applications requiring ultra-low input bias current.

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 INA114AU 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 INA114AU are the AMP02FSZ (Analog Devices Inc.) and the INA111AU (Texas Instruments), 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 INA114AU 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 INA114AU (Texas Instruments) is a part in the Linear category. This page lists qualified, cross-referenced replacements for it with a side-by-side comparison.
