| FFF Compatibility | It uses the identical SOIC-28 (DVA) package where only 8 physical pins are populated, matching the exact footprint and pinout assignments.The physical dimensions, package outline, and SMD mounting style are completely identical.It has slightly higher maximum nonlinearity (0.020% FSR for ISO122U vs 0.010% FSR for ISO124U). | It is a through-hole PDIP-16 package (with 8 physical leads), which cannot mount on the SMD SOIC-28 land pattern.The mounting type is through-hole (THT) instead of surface-mount (SMD).It delivers identical electrical performance, input/output voltage range, and isolation ratings as the ISO124U. | ||
 AI Summary | ISO124U by Texas Instruments: Isolation Amplifier 1 Circuit 8-SOIC. | The ISO122U is a direct sibling from the same isolation amplifier family, sharing the exact same physical SOIC-28 package layout with 8 populated pins. It offers a near-identical electrical specification but features a slightly relaxed maximum nonlinearity spec. This makes it an ideal drop-in option if the target application can tolerate a minor reduction in precision.
| The ISO124P is the through-hole sibling of the ISO124U, featuring the identical internal silicon die. It provides the same high precision and 0.010% maximum nonlinearity in a PDIP-16 package (with 8 populated pins). It is a suitable alternative for designs that can accommodate a through-hole footprint or undergo a board redesign.

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 ISO124U is active and in production. The parts listed here are qualified equivalents if you need a second source or better availability.
The closest qualified second sources for the Texas Instruments ISO124U are the ISO122U (Texas Instruments) and the ISO124P (Texas Instruments), out of 3 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 ISO124U 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 ISO124U (Texas Instruments) is a part in the Linear category. This page lists qualified, cross-referenced replacements for it with a side-by-side comparison.
