TE Connectivity 3-6318490-6 产品概述

一、概述

TE Connectivity(泰科电子)型号 3-6318490-6 是一款面向板对板(Board-to-Board)连接的竖装可插拔受座(PCB Mount Receptacle),220 针,间距 0.5 mm,双排立贴(SMD)封装。该连接器用于高密度信号传输场合,黑色外壳、触头镀金,支持“Free Height”安装方式,可实现可靠的低电阻接触和重复插拔性能。

二、主要规格

  • 引脚数:220P(2 排,每排 110 针,0.5 mm 中心距)
  • 安装方式:表面贴装(SMD),立贴(Vertical)
  • 额定电流:500 mA / 针
  • 额定电压:50 V
  • 触头镀层:金(接触面)
  • 工作温度:-40 ℃ 至 +85 ℃
  • 颜色与材料:黑色绝缘体,金属触点镀金处理
  • 封装/脚距:P = 0.5 mm,适合高密度 PCB 布局

三、结构与材料

该受座采用双排紧凑布局,绝缘体材料耐高温并适配标准回流焊工艺,触点采用铜合金基材并经镀金处理以保证长期低接触电阻和抗氧化能力。外壳设计兼顾插入力与插拔寿命,通过结构锁扣或定位柱实现贴装稳定性。

四、关键特性

  • 高密度:0.5 mm 间距、220 针设计,节省 PCB 面积,适合紧凑系统
  • 良好信号完整性:短接触长度和金触点减少接触阻抗,适合高速/差分信号(需按具体频率和布局验证)
  • 可回流焊:SMD 封装兼容主流回流焊曲线,便于自动化贴装与生产
  • 工作环境宽:-40℃~+85℃ 满足工业级温度要求
  • 安全电气:500 mA/针与 50 V 额定确保一般信号与低功率供电需求

五、典型应用场景

  • 消费电子、平板和笔记本内部模块互联
  • 通信设备和网络设备的板对板信号连接
  • 工业控制、测量仪器内部子板连接
  • 汽车电子(非高温或高功率主电路)及其他嵌入式系统

六、PCB 设计与贴装建议

  • 严格按照制造商推荐的焊盘与孔位尺寸布局,保持 0.5 mm 间距的焊盘间距和阻焊开窗清晰。
  • 回流焊工艺需控制温度曲线,避免过热导致塑料基体变形或金属镀层损伤。
  • 若为板对板连接,注意母板与公板之间的对齐公差和配合高度(Free Height),并留出插拔空间。
  • 对高速信号,按差分对与参考平面布局,必要时做阻抗匹配和去耦处理。

七、选型与注意事项

  • 核实实际电流和电压需求,若存在更高功率或更严格的耐振要求,考虑更高额定的连接器或增加引脚数分担电流。
  • 评估插拔次数和机械寿命,频繁插拔场景需确认触点寿命和保持力。
  • 若在恶劣环境(高湿、高盐雾)使用,确认是否需要特殊镀层或密封设计以防腐蚀。
  • 与 TE 官方资料核对详细的机械图纸、焊盘推荐和环境测试报告以完成最终验证。

以上为 3-6318490-6 的产品概述与实用建议,可作为选型与 PCB 设计初步参考。若需更详细的机械图、焊盘尺寸或电气与可靠性测试数据,建议参考 TE Connectivity 官方数据手册或联系供应商获取完整资料。

Sourcing availability signal

Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.

Buyer sourcing scenarios

Examples of how common component sourcing requests are organized.

Typical RFQ scenarios based on the WMSIC form fields, catalog data, manual review steps, and shipment preparation workflow.

The buyer shares the full part number, package requirement, quantity, destination, and available product photos so the quotation can record the exact version under review.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
