Samtec TFM-105系列连接器选型及国产平替型号对照表

时间：2026-08-28 浏览量：26 分类：技术中心

TFM-105是Samtec Tiger Eye™家族的一款微型连接器，1.27mm间距，双排2×5P共10个引脚。这个间距在保证连接可靠的前提下，比传统2.54mm方案省了不少PCB面积，高密度板子用得多。

Tiger Eye™端子是这套系统的核心——多指铍铜触芯，插拔寿命和可靠性都做得不错。触头材质是磷青铜，表面镀金或镀锡可选。数据速率能跑到8 Gbps，单触头额定电流最高3.7A，耐压250VAC/354VDC。绝缘体是黑色LCP，UL94 V-0阻燃，工作温度-55°C到+125°C，常规工业环境够用。

型号怎么读？拿TFM-105-02-S-D-A拆开看：

TFM — 系列代号，Tiger Eye™微型端子条
105 — 10针，双排2×5P
02 — 引脚长度/高度代码，不同数字对应不同的配接长度和绝缘体高度
S — 镀层。S是10µin镀金，L也是10µin镀金但带锡，H是30µin镀金
D — 双排。S是单排
A — 附加选项，比如对齐销、锁紧夹

实际选型的时候，安装方式（SMT还是通孔）、组装方向（垂直、直角、水平）和镀层厚度这三个参数要先定下来。镀层厚了耐用但贵，薄了便宜但插拔次数少，按项目需求来。另外TFML系列带锁定功能，振动大的场景可以考虑。

搭配方面，TFM-105可以跟Samtec好几款插座和电缆组件配对：

板对板 — 配SFM、SFMC系列插座
线对板/电缆 — 配SFSD、SFSDT、TFSD、TFSDT等电缆组件
IDC电缆 — 配对应的IDC连接器

壳体带护罩，支持盲插，推挽式紧固。工业控制、通信基站、服务器、医疗设备这些场景用得比较多。振动环境严苛的场合，可以选螺丝紧固或锁紧夹的版本。
