| FFF Compatibility | Housed in the identical 8-PDIP package and standard pinout matches perfectly. Pin 8 is used for an optional speed boost, but leaving it floating matches the original's no-connection (NC) on pin 8.Identical physical 8-DIP footprint and mounting dimensions.An outstanding high-performance precision JFET-input op-amp. Slew rate, bandwidth, bias current, and offset voltage meet or exceed the original specifications. | Housed in a surface-mount SOIC-8 package. Requires a physical adapter board (e.g., SOIC-8 to DIP-8) to mount onto the same through-hole circuit board.Surface mount package (SOIC-8) compared to the original through-hole 8-DIP.Outstanding electrical specifications that easily exceed the performance of the OPA627 in noise, speed, and precision. | ||
 AI Summary | OPA627AP by Texas Instruments: Standard (General Purpose) Amplifier 1 Circuit 8-PDIP. | The LT1122CCN8#PBF is a premium, active JFET-input operational amplifier in the identical through-hole 8-DIP package. It offers a direct match in input offset voltage (130 µV) and exceeds the slew rate of the original (75 V/µs vs 55 V/µs), making it an outstanding drop-in replacement. Pin 8 can be left floating to match the OPA627's NC (no connection) behavior, or tied to V+ for a performance boost.
| The OPA828ID is the official, manufacturer-recommended modern successor to the OPA627 series. While its electrical characteristics represent a massive performance upgrade, it is only available in a surface-mount SOIC-8 package. This requires a small SOIC-8 to DIP-8 adapter board to physically mount onto a board originally designed for the OPA627AP.

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 OPA627AP 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 OPA627AP are the LT1122CCN8#PBF (Analog Devices Inc.) and the OPA828ID (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 OPA627AP 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 OPA627AP (Texas Instruments) is a part in the Linear category. This page lists qualified, cross-referenced replacements for it with a side-by-side comparison.
