640445-7 产品概述

一、产品简介

640445-7 为 TE Connectivity(泰科电子)MTA‑156 系列的插针排组件,形式为单排 1×7 插针(7P),节距 3.96 mm,直插(通过孔)安装。该件通常以插件式接插件形式供应,用于将线束或 IDC 端子与电路板进行可靠连接。标注为 “MTA156 HDR ASSY FL/STR SN”,触点为锡镀,整件适用于需要稳定电气连接与良好机械强度的工业与电子设备场合。备注:样品不拆单销售。

二、主要性能参数

  • 排列/针数:单排 1×7,总针数 7P
  • 节距:3.96 mm(MTA‑156 标准节距)
  • 安装方式:直插(通过孔安装)
  • 额定电流:14.24 A(单针额定)
  • 额定电压:600 V
  • 触头材质:铜合金,保证良好导电性与机械强度
  • 触头镀层:锡(Sn),便于焊接且具有良好耐蚀性
  • 工作温度范围:-55 ℃ ~ +105 ℃
  • 塑壳阻燃等级:UL94 V‑0,提升安全性与耐火性

三、产品特点与优势

  • 高电流承载能力:单针可达 14.24 A,适合低压大电流的连接需求,适用于电源分配与动力传输场景。
  • 可靠的接触性能:铜合金触点配合锡镀层,综合了低接触电阻与优良的焊接性。
  • 宽温度适应性:-55 ℃ 到 +105 ℃ 的工作范围,满足工业级与恶劣环境需求。
  • 安全合规:塑料件通过 UL94 V‑0 阻燃等级认证,提高整机安全性。
  • 机械兼容性:标准 3.96 mm 节距,方便与 MTA‑156 系列 IDC 插座及常见线端配套使用,便于系统扩展与维护。

四、典型应用场景

  • 工业控制与自动化设备:电源与信号分配、模块间连接。
  • 通信与网络设备:配线架与线束接口。
  • 家用电器与电源设备:内部电源连接、分支点。
  • 仪器仪表与测试设备:可靠的可重复插拔连接需求场合。
  • 其它需要线对板快速可靠连接的场景。

五、安装与使用建议

  • 焊接兼容性:锡镀触点适合波峰焊和手工焊接,但建议遵循厂家推荐的焊接温度与时长以避免塑料件受热变形。
  • 机械固定:通过孔插装后应保证焊点饱满、焊料覆盖良好,避免因振动造成接触不良;在高电流应用中,注意 PCB 走线截面积与散热设计。
  • 布线建议:若单针电流接近额定值上限,建议在 PCB 上采用更宽更厚的铜箔或并联多针分担电流以降低发热。
  • 防护与清洁:使用适合的清洗剂进行清洁,避免使用强腐蚀性溶剂长期接触。

六、可靠性与选型注意事项

  • 电气耐受度:选型时核对实际工作电压、电流、环境温度,考虑一定的裕量与降额使用。
  • 配套件兼容性:与 MTA‑156 系列 IDC 插座、线束配件配合使用以保证可靠插拔与机械咬合。
  • 储存与运输:建议原包装保存,避免潮湿与腐蚀性气体环境,出厂前检查镀层与外观完整性。
  • 采购提示:确认所需为直插(through‑hole)式 1×7、锡镀版本,零件号 640445‑7 对应的具体包装与交期以供应商出具为准。

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
