| FFF Compatibility | Pins 1 and 5 are NC (No Connect) on the OPA828, whereas they were used for Offset Null adjustment on the original ADA4627-1. If the system design leaves these trim pins floating, it is a direct drop-in.Both parts use the standard 8-pin SOIC surface-mount package (0.154" / 3.90mm width) with identical physical dimensions.Exceeds all key electrical performance parameters including supply voltage limit (36 V max vs 30 V max), noise, offset voltage, and speed. | Pins 1 and 5 are NC (No Connect) on the OPA627 SOIC package, whereas they were used for Offset Null on the ADA4627-1. Compatible if offset null pins are unused.Both parts use the standard 8-pin SOIC surface-mount package footprint.Matches the JFET input topology, precision DC offset (130 µV vs 120 µV), and excellent noise parameters. | ||
 AI Summary | ADA4627-1ARZ by Analog Devices: J-FET Amplifier 1 Circuit 8-SOIC. | The OPA828 represents the next-generation upgrade for high-performance JFET input amplifiers. It provides significantly improved AC speed and DC precision in an active, long-term supported component.
| The OPA627 is a highly-regarded, active industrial standard for precision JFET applications. It maintains the required high-voltage rails and low distortion profiles of the original.

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 Analog Devices ADA4627-1ARZ 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 Analog Devices ADA4627-1ARZ are the OPA828IDR (Texas Instruments) and the OPA627AU (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 ADA4627-1ARZ 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 ADA4627-1ARZ (Analog Devices) is a part in the Linear category. This page lists qualified, cross-referenced replacements for it with a side-by-side comparison.
