Replacement Taptic Engine part for Magic Trackpad 2

My Magic Trackpad 2 recently stopped “clicking.” It still tracks and recognises clicks/taps, but the entire haptic feedback is gone. I’ve tried various software remedies that I found online (deleting plists, resetting PRAM, etc.) but no luck, even on another device. Seems to be a hardware problem, presumably inside the Taptic Engine.

I see it is not impossible to open up the Magic Trackpad 2 and to get at the Taptic Engine. Does anybody know if I can get a replacement part for it anywhere?
