on one’s behalf和in one’s behalf有区别吗?

on one's behalf和in one's behalf有区别吗?
例如：
Don't trouble to do it on my behalf.不要为了我去麻烦了.
He interceded in my behalf.他替我说情.
这两句的on one's behalf和in one's behalf可以互换吗?

on one's behalf 和 in one's behalf 很接近,但是有些细微差别.
in one's behalf 用在 in the interest of ...;
on one's behalf 用在 on the part of ...;
Don't trouble to do it on my behalf. (不要为了我去麻烦了.)
He interceded in my behalf. (他替我说情.)
这两句的on one's behalf 和 in one's behalf 互换以后,意思有差别.
Don't trouble to do it on my behalf.
准确的翻译是：不要(代)替我去做这件麻烦事.
如果换成: in
Don't trouble to do it in my behalf.
不要为了我的利益去做这件麻烦事了.
He interceded in my behalf.(他替我说情.)
准确的翻译是：他为我的利益去说情.
如果换成: on
He interceded on my behalf.
他代表我去调解.
