Note: Can fix to shimano r7150 rear derailleur?

Yes — the Shimano RD‑R7000 bracket axle unit (Y3F398020) that you mentioned is indeed compatible with the RD‑R7150 rear derailleur (as well as RD‑R7000‑SS, RD‑R7000‑GS, and RD‑RX400), but you’ll need the R7150‑specific version to ensure proper fit and function.

✔️ Compatibility Details:
Y3F398020 is the bracket axle unit originally for RD‑R7000 (normal type).

Shimano’s parts catalog now lists a Y3HY98020 variant for RD‑R7150 (12‑speed Di2), which has been confirmed to fit RD‑R7000, RD‑R7100, RX400, and R7150 derailleurs.

So technically, if you have the Y3HY98020 unit (branded for R7150), it will fit on an RD‑R7000 derailleur. And conversely, the same bracket will work on an RD‑R7150.

⚠️ What Matters:
Shimano updated its part numbering from Y3F398020 (an 11‑speed bracket) to Y3HY98020 (the 12‑speed Di2-compatible version). While they share much hardware design, the newer part ensures proper alignment and spacing for Di2 electronics and 12‑speed chain wrap.

✅ Conclusion:

If your Y3F398020 is genuine R7000‑series (11‑speed) part, it's compatible with R7150 (Di2 12-speed), but Shimano recommends using the Y3HY98020 which is certified for R7150 and its Di2 setup.

They’re effectively interchangeable across these models — R7000‑SS/GS, R7100, RX400, and R7150 (Di2) — provided you use the normal‑type bracket axle unit.
