1.同一型號(hào)IC的代換
同一型號(hào)IC的代換一般是可靠的，安裝集成電路時(shí)，要注意方向不要搞錯(cuò)，否則，通電時(shí)集成電路很可能被燒毀。有的單列直插式功放IC，雖型號(hào)、功能、特性相同，但引腳排列順序的方向是有所不同的。例如，雙聲道功放IC LA4507，其引腳有“正”、“反”之分，其起始腳標(biāo)注（色點(diǎn)或凹坑）方向不同；沒有后綴與后綴為"R"的IC等,例如 M5115P與M5115RP.
2.不同型號(hào)IC的代換
⑴型號(hào)前綴字母相同、數(shù)字不同IC的代換。這種代換只要相互間的引腳功能完全相同，其內(nèi)部電路和電參數(shù)稍有差異，也可相互直接代換。如：伴音中放IC LA1363和LA1365，后者比前者在IC第⑤腳內(nèi)部增加了一個(gè)穩(wěn)壓二極管，其它完全一樣。
⑵型號(hào)前綴字母不同、數(shù)字相同IC的代換。一般情況下，前綴字母是表示生產(chǎn)廠家及電路的類別，前綴字母后面的數(shù)字相同，大多數(shù)可以直接代換。但也有少數(shù)，雖數(shù)字相同，但功能卻完全不同。例如，HA1364是伴音IC，而uPC1364是色解碼IC；4558，8腳的是運(yùn)算放大器NJM4558,14腳的是CD4558數(shù)字電路；故二者完全不能代換。
