TE Connectivity 640456-4 产品概述

一、产品概况

TE Connectivity 型号 640456-4 为 MTA 100 系列垂直直插 PCB 接针座(PCB Mount Header),4 位(1x4P),节距 2.54 mm(0.1 in),部分护套设计,适用于信号线连接的插针端子。该件为通孔(Through Hole)焊接安装,触头为铜合金并镀锡,额定电流 5A、额定电压 250V,工作温度范围 -55℃ 至 +105℃,塑壳阻燃等级达到 UL94V-0。

二、主要参数与材料

  • 引脚排列:1x4(每排 4 针),总针数 4P
  • 节距:2.54 mm(0.1 in)
  • 安装方式:直插(Through Hole)- 焊接(Solder)
  • 额定电流:5 A;额定电压:250 V
  • 触头材质:铜合金;表面处理:镀锡(Tin)
  • 塑壳阻燃等级:UL94V-0
  • 工作温度:-55℃ ~ +105℃

三、结构特点

该款 PCB 直插座为垂直式线对板(Wire-to-Board)接口,采用部分护套(Partially Shrouded)设计,能够在一定程度上引导配合端子插拔并提供有限的防错位功能。通孔插件结构提升了机械强度与焊点可靠性,适合经受插拔力或振动工况。

四、典型应用场景

适用于工业电子、控制板、通信设备、仪表仪器、消费电子样机和测试治具等需要可靠信号连接的场合。其 2.54 mm 标准节距使其与常见 IDC 排线、单排插座及面板线缆系统兼容,便于快速原型设计与生产装配。

五、性能与优势

  • 电气性能可靠:5A 的额定电流与 250V 的额定电压满足多数信号与低功率电源传输需求。
  • 良好接触与焊接性:铜合金触头镀锡,既保证导电性又利于波峰/回流焊接工艺。
  • 机械稳固:通孔直插结构与部分护套设计提高插拔耐久性与防错位能力。
  • 可靠的环境适应性:宽温范围与 UL94V-0 阻燃等级适合工业级应用。

六、选型与配置建议

  • 若需更高电流或更强耐腐蚀性能,可考虑无铅镀金或更大截面引脚的替代件。
  • 与 TE MTA 100 系列的配套线束/插头配合使用,可获得更快的线束装配效率。
  • 设计 PCB 时建议参考通孔焊盘与孔径规范,确保焊接强度与定位精度。

七、装配与使用注意

  • 波峰焊或手工焊接时控制温度曲线,避免长时间高温导致塑壳变形或性能退化。
  • 插拔时尽量沿导向方向施力,避免侧向扭曲引脚导致焊点损伤。
  • 储存与使用环境避免长期潮湿,以减少表面氧化和焊接不良风险。

此产品适合需要标准节距、可靠通孔安装和工业级耐受性的线对板连接场合,兼顾装配效率与电气机械性能,是常见的通用信号连接解决方案。若需完整尺寸图、力学参数或可焊性报告,建议参考 TE Connectivity 官方数据手册或联系供应商获取相关资料。

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
