I’m pretty sure they not the same. The replacment assembly I bought came with:
- Left hotend heating assembly (pre-installed with cable sheet) × 1
- Wind blocker × 1
- M1.6×4 screws (for securing the cable sheet and wind blocker) × 2
- M2.5×7 screws (for securing the left hotend heating assembly) × 4
Bambu Lab has outstanding documentation. The Wiki is fantastic. It falls down on this point though, My guess is you install the wind blocker on top of the cable sheet but thats a challenge given the location you need to mount in on. I woiuld also be a poor design, which would be unusual for Bambu.
But like I mentioned, the Wiki make no mention of the “wind blocker” when it talks about reinstalling the assembly. Unfortunately I didn’t pay close attention when I removed the old unit. It was my first encounter with “the blob of death” and things were quite a mess.
