| FFF Compatibility | Exactly shares the same SOIC-8 footprint and pin assignments, including Pin 7 being No Connect (NC).Housed in the identical 8-SOIC package (3.90mm width) and mounting style.Meets or exceeds all performance specifications (225 MHz GBW, 52V/µs slew rate, and 4V to 33V supply range) over a wider industrial temperature range. | Pin 7 is designated as Power-Down (PD) instead of No Connect (NC). However, because PD is internally pulled high, leaving it unconnected on an NC pad naturally enables the device.Uses the exact same SOIC-8 package and mechanical envelope.Provides identical electrical performance, input/output structures, and voltage safety ceilings (33V max). | ||
 AI Summary | THS4131CD by Texas Instruments: Differential Amplifier 1 Circuit Differential 8-SOIC. | The THS4131IDR is the direct manufacturer-recommended replacement for the obsolete THS4131CD. It offers identical electrical parameters and pinout, with the only differences being a superior operating temperature range (-40°C to +85°C) and shipping carrier (tape and reel).
| The THS4130IDR belongs to the same family as the THS4131 but features an active-low Power-Down (PD) pin on Pin 7 instead of No Connect (NC). Since the PD pin has an internal pull-up resistor, it will naturally remain enabled if placed directly onto a PCB designed for the THS4131CD with Pin 7 left floating.

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 THS4131CD 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 THS4131CD are the THS4131IDR (Texas Instruments) and the THS4130IDR (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 THS4131CD 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 THS4131CD (Texas Instruments) is a part in the Linear category. This page lists qualified, cross-referenced replacements for it with a side-by-side comparison.
