| FFF Compatibility | Pins match exactly (1: VIN-, 2: VOCM, 3: V+, 4: VOUT+, 5: VOUT-, 6: V-, 7: Enable, 8: VIN+).Standard SOIC-8 package with identical physical dimensions.Identical electrical characteristics, including 180 MHz bandwidth, 50 V/µs slew rate, and 32 V maximum supply voltage. | Pin assignments are identical, with Pin 7 acting as the active-low power-down (PD) which is logic-compatible with OPA1632's Enable.Packaged in the standard SOIC-8 footprint.Slightly lower bandwidth (150 MHz vs 180 MHz) and higher supply current (12.3 mA vs 14 mA). | ||
 AI Summary | OPA1632D by Texas Instruments: Audio Amplifier 1 Circuit Differential 8-SOIC. | The OPA1632DR is the active tape-and-reel version of the obsolete tube-packaged OPA1632D. Since it uses the exact same silicon design and SOIC-8 package, it is a 100% direct drop-in replacement with no redesign needed.
| The THS4130IDR is a high-voltage fully differential amplifier in the same SOIC-8 package. It supports a similar supply voltage range up to 33 V, and its active-low power-down pin functions with the same operating logic as the OPA1632's active-high enable pin.

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 OPA1632D 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 OPA1632D are the OPA1632DR (Texas Instruments) and the THS4130IDR (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 OPA1632D 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 OPA1632D (Texas Instruments) is a part in the Linear category. This page lists qualified, cross-referenced replacements for it with a side-by-side comparison.
