Definition
代换 means 'to replace' or 'to substitute', but it is more formal and technical than everyday words like 代替 or 替换. You'll often see it in mathematics (variable substitution), chemistry (ion substitution), or formal writing. It can also refer to the rhetorical device 'hypallage', but that use is rare.
