take place of是代替,一般都是用來表示代替（.的位置）,比如說It would be difficult to find a man to take the place of the secretary.找一個(gè)代替秘書的人會(huì)很難的.再比如說一項(xiàng)新的技術(shù)代替了舊的技術(shù)等.放在這里不通順了.
instead of是（用…)代替…,(是…)而不是…,(用…)而不用…
take the place of是動(dòng)詞短語,表示：取代……的位置,如：
He took the place of mine as the manager.
Now computers have taken the place of many old things.
instead of是介詞短語,表示“而不是……”,如：
Instead of staying at home,he went out to play football.
He went to the lecture instead of me.
