Is there any difference in meaning and usage between the phrase on one's part and for one's part in the sense of something being done by someone or experienced? For example:

  1. There were a few mistakes on my part.
  2. There were a few mistakes for my part.
  3. If you cook a meal, I will do the dishes on my part.
  4. If you cook a meal, I will do the dishes for my part.

1 indicates that you are responsible for some mistakes.

2 Isn't using the phrase "for my part". It indicates that for your "part" (perhaps a script for a play) there were some mistakes made. Perhaps they got you the wrong costume.

3 Doesn't make sense.

4 Is fine, but cumbersome. A native English speaker would probably say "If you cook a meal, then I'll do my part by doing the dishes."

"on my part" is usually used to indicate something that proceeds from your actions [in a group of other actions possibly by other people], rather than to indicate you performed a specific action yourself. In your example you are saying that you are responsible for a few mistakes.

"for my part" is used to indicate that something forms your share of some set of actions. For my part I'll drive you over, if you do your part by paying for the fuel.
