| FFF Compatibility | Shares the exact same SOIC-8 footprint and pinout assignments.Identical physical package size and surface mount style.Maximum supply voltage span is narrower (36 V / ±18 V vs 48 V / ±24 V), making it incompatible if the application utilizes rails above ±18 V. | Matches the industry-standard dual op-amp pinout in SOIC-8.Identical 8-pin SOIC surface mount package dimensions.Maximum supply voltage is limited to ±18 V (36 V total span) and bandwidth is lower at 11 MHz compared to the original's 20 MHz. | ||
 AI Summary | OPA2604AUG4 by Texas Instruments: Standard (General Purpose) Amplifier 2 Circuit Differential 8-SOIC. | The OPA1656IDR is an ultra-low-noise, high-performance audio operational amplifier that serves as an excellent upgrade if the power supply rails do not exceed ±18V. It offers superior AC specifications, including a massive 53 MHz bandwidth and high current output capability.
| The OPA1642AIDR utilizes JFET inputs with exceptionally low bias currents, making it ideal for high-impedance audio applications. While it has lower bandwidth and voltage limits, it provides exceptional sound quality and lower noise performance.

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 OPA2604AUG4 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 OPA2604AUG4 are the OPA1656IDR (Texas Instruments) and the OPA1642AIDR (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 OPA2604AUG4 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 OPA2604AUG4 (Texas Instruments) is a part in the Linear category. This page lists qualified, cross-referenced replacements for it with a side-by-side comparison.
