直接代換是指用其他IC不經任何改動而直接取代原來的IC，代換后不影響機器的主要性能與指標。
其代換原則是：代換IC的功能、性能指標、封裝形式、引腳用途、引腳序號和間隔等幾方面均相同。其中IC的功能相同不僅指功能相同；還應注意邏輯極性相同，即輸出輸入電平極性、電壓、電流幅度必須相同。例如：圖像中放IC，TA7607與TA7611，前者為反向高放AGC，后者為正向高放AGC，故不能直接代換。除此之外還有輸出不同極性AFT電壓，輸出不同極性的同步脈沖等IC都不能直接代換，即使是同一公司或廠家的產品，都應注意區分。性能指標是指IC的主要電參數（或主要特性曲線）、耗散功率、工作電壓、頻率范圍及各信號輸入、輸出阻抗等參數要與原IC相近。功率小的代用件要加大散熱片。其中
