| FFF Compatibility | Standard SOIC-8 pinout and package dimensions match the OPA2604AUE4 exactly.Identical SOIC-8 package width (3.90mm) and mounting requirements.Maximum supply voltage is 44V (±22V) compared to OPA2604's 48V (±24V); input bias current is higher (100nA vs 100pA) due to its bipolar-JFET input stage. | Pinout configuration matches the standard dual op-amp configuration of the OPA2604AUE4 perfectly.Identical SOIC-8 surface mount package with 3.90mm width.Maximum supply voltage is limited to 36V (±18V) compared to the original 48V (±24V), and gain bandwidth is lower (8 MHz vs 20 MHz). | ||
 AI Summary | OPA2604AUE4 by Texas Instruments: Standard (General Purpose) Amplifier 2 Circuit Differential 8-SOIC. | The OP275GSZ is a premium dual audio op-amp designed with a Butler front-end that combines JFET and bipolar technologies to match the warm audio performance of the OPA2604. Crucially, it supports a high supply voltage up to 44V (±22V), which is closest to the original's 48V rating. However, verify that your supply rails do not exceed ±22V before drop-in replacement.
| The OPA2134UA is the direct standard Burr-Brown successor designed to replace the OPA2604 in applications with supply rails up to ±18V. It offers exceptional JFET-input audio performance and very low distortion, making it a highly reliable replacement for standard ±15V or ±18V systems. Ensure that your actual circuit rails do not exceed ±18V before placing this part.

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 OPA2604AUE4 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 OPA2604AUE4 are the OP275GSZ (Analog Devices Inc.) 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 OPA2604AUE4 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 OPA2604AUE4 (Texas Instruments) is a part in the Linear category. This page lists qualified, cross-referenced replacements for it with a side-by-side comparison.
