它们的类型相同都是NPN管，主要参数（耐压、电流、增益、带宽）相同，封装外形也相同，从数据手册中看，好象只有允许耗散功率方面有点差异，MPSW42略大于MPSA42，所以用MPSW42替换MPSA42肯定是可以的，如果想用MPSA42替换MPSW42就要看看实际功耗够不够。
三极管，全称应为半导体三极管，也称双极型晶体管、晶体三极管，是一种控制电流的半导体器件·其作用是把微弱信号放大成幅度值较大的电信号， 也用作无触点开关。晶体三极管，是半导体基本元器件之一，具有电流放大作用，是电子电路的核心元件。三极管是在一块半导体基片上制作两个相距很近的PN结，两个PN结把整块半导体分成三部分，中间部分是基区，两侧部分是发射区和集电区，排列方式有PNP和NPN两种。
