漢字を間違えた。
I mistook the kanji (I used the wrong one).
漢字が間違っている。
The kanji is wrong.
Many kanji mistakes involve visually similar characters (e.g., 未 vs 末, 人 vs 入) or homophones (e.g., 会う vs 合う, 早い vs 速い). When explaining, you can say 「形が似ているから間違えた」(I mistook it because the shapes are similar) or 「読み方が同じだから間違えた」(I mistook it because the reading is the same).
