Alternatives to Texas Instruments OPA655U
Texas Instruments OPA655U and its qualified second sources, compared on form, fit and function, stock, lifecycle and price — the same checks Parter runs inside a BOM.
Equivalent and substitute parts for Texas Instruments OPA655U

|---|---|---|
| FFF Compatibility | The pinouts are not fully identical; the source part utilizes Pins 5 and 8 as secondary power supply pins (+VS2 and -VS2) for noise/distortion optimization, whereas the alternative leaves these pins as No Connection (NC).Both parts are housed in standard 8-pin SOIC (SO-8) packages with equivalent physical dimensions and mounting styles.The Gain Bandwidth Product (GBW) is slightly lower (230 MHz vs 240 MHz). Additionally, the alternative lacks the secondary power supply pins of the original, which are designed to reduce package lead inductance and optimize high-frequency distortion. | |
OPA655U by Texas Instruments: Voltage Feedback Amplifier 1 Circuit 8-SOIC. | The OPA656U is a highly compatible alternative to the OPA655U, offering improvements in input bias current, offset voltage, slew rate, and unity-gain bandwidth. However, it features a slightly lower Gain Bandwidth Product (230 MHz vs 240 MHz) and lacks the secondary power supply pins (Pins 5 and 8 are NC on the alternative vs ±VS2 on the source) used for distortion reduction.

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.
