【选型】4G通讯基站线对板牛角连接器国产化替代，PCB LAYOUT无需改动

时间： 2021-03-21 来源：世强

技术问答

某客户的4G通讯基站项目为了实现电子零部件国产化的目标，需要将原使用进口品牌SAMTEC料号为EHF-120-01-L-D-RA的牛角连接器改成国产厂家的替代品。考虑到尽可能的减少替换物料差异点带来的项目改动成本，要求替代物料的针脚尺寸必须一致（以避免修改PCB LAYOUT）,外形尺寸差异不能太大，否则可能会与其它元器件存在结构干涉。

如下图图一与图二对比可见,，美系厂家SAMTEC料号为EHF-120-01-L-D-RA的牛角连接器,与国产维峰厂家料号为3231-20RS3BST1牛角连接器的针脚尺寸是一致的，所以在不改动PCB LAYOUT的情况下即可顺利下板。在结构外形上两家是有细微区别，但是重点的长宽高尺寸是一致的，所以不会与板上的其它物料存在结构干涉。综上维峰厂家料号为3231-20RS3BST1牛角连接器可以完美替代进口品牌SAMTEC料号为EHF-120-01-L-D-RA的牛角连接器。
