Depends on the part. Non-OEM laptop memory? Fine. The failure/error rate is usually negligbly higher than OEM if at all. Non-OEM laptop batteries? Not fine. These very reliably work less well and fail or lose capacity much sooner. I imagine similar differences exist for many other kinds of parts as well.
