3.类型相同但引脚功能不同IC的代换  
这种代换需要改变外围电路及引脚排列，因而需要一定的理论知识、完整的资料和丰富的实践经验与技巧。  
4。有些空脚不应擅自接地  
内部等效电路和应用电路中有的引出脚没有标明，遇到空的引出脚时，不应擅自接地，这些引出脚为更替或备用脚，有时也作为内部连接。  
5.用分立元件代换IC  
有时可用分立元件代换IC中被损坏的部分，使其恢复功能。代换前应了解该IC的内部功能原理、每个引出脚的正常电压、波形图及与外围元件组成电路的工作原理。同时还应考虑：  
⑴信号能否从IC中取出接至外围电路的输入端：  
⑵经外围电路处理后的信号，能否连接到集成电路内部的下一级去进行再处理（连接时的信号匹配应不影响其主要参数和性能）。如中放IC损坏，从典型应用电路和内部电路看，由伴音中放、鉴频以及音频放大级成，可用信号注入法找出损坏部分，若是音频放大部分损坏，则可用分立元件代替。
