| FFF Compatibility | Exactly matches the standard dual op-amp SOIC-8 pinout.Housed in an identical 8-SOIC (150 mil) package.Maximum supply voltage is limited to ±18 V (36 V span) compared to the ±24 V (48 V span) of the OPA2604. | Matches the standard dual op-amp SOIC-8 pinout.Uses the same 8-SOIC package footprint.Supply voltage span is limited to 36 V (±18 V) and Gain Bandwidth Product is lower (8 MHz vs 20 MHz). | ||
 AI Summary | OPA2604AU/2K5 by Texas Instruments: Standard (General Purpose) Amplifier 2 Circuit Differential 8-SOIC. | The OPA1656IDR is an exceptional modern audio-optimized operational amplifier offering far lower noise and distortion than the original. It serves as an excellent upgrade provided the power supply rails are configured at or below ±18 V.
| The OPA2134UA is a classic, highly popular JFET-input audio operational amplifier. It provides very low distortion and a similar signature sound, though it trades off supply voltage capability and bandwidth compared to the OPA2604.

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 OPA2604AU/2K5 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 OPA2604AU/2K5 are the OPA1656IDR (Texas Instruments) and the OPA2134UA (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 OPA2604AU/2K5 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.
