interchangeable?

Difference between 交替 and 交代
They're mostly interchangeable.

If you want to be nit-picky, 交替 is for regularly occurring changes, and 交代 is
for one-time changes, but this is not a hard-set rule.

I would like to give further information since Mr. Blavius asserts **交代 is for
one-time changes, but this is not a hard-set rule.** and per choco san's
advice.

From the site,

> 交代・・・役目などが一回限りでかわる時
>
> 交替・・・かわって行うことが繰り返されるとき

Translated

> 交代 --- one time change of roles or jobs or plays etc etc,
>
> 交替 --- repetitive change of roles or jobs or plays etc, etc.

And from the above

>
> つまり、スポーツの選手交代など、一度変わった後は、もう元に戻ることができない状況の事を「交代」と呼ぶのです。これに対し「交替」の「かわって行うことが繰り返されるとき」というのは、AからBに変わって、またAに戻ったり、またBに戻ったりする時を指します。例えば、警備の担当や仕事の当番など、何回も変わったりする時には「交替」を使うということですね！

Translated

Examples respectively from the source.

交代

> 会社が世代交代していく。

Translated

> Generational changes of company's important members ( such as bosses ).

**Would the previous bosses come back 50 years later? Quite unlikely**

交替

> 昼夜交替

Translated

> Day and night shift ( works ).

**A person A can not work day and night 5 days a week ( for example ). Please
think about the above mentioned guard men's case kindly**

Have a nice day.
