TE Connectivity 3-643814-4 产品概述
一 产品简介
3-643814-4 是 TE Connectivity（泰科电子）MTA 100 系列的 1x4 位插座连接器组件，间距 2.54 mm（0.1 in），采用绝缘位移（IDC）接线结构，适用于线对板连接（wire-to-board）。该件为镀锡触点（Sn）、铜合金触头，额定电流 5 A，额定电压 250 V，适合需要可靠快速布线的电子装配场景。
二 主要参数
- 排数/极数：1 排 × 4 针（1x4P）
- 中心距：2.54 mm（0.1 in）
- 额定电流：5 A
- 额定电压：250 V
- 工作温度范围：-55 ℃ ～ +105 ℃
- 触头材质：铜合金；触头镀层：锡（Sn）
- 绝缘体耐燃等级：符合 UL 94V-2 标准
- 安装方式：自由悬挂（线束端悬空或配合面板/PCB 插合）
三 结构与材料特点
该连接器采用 IDC（绝缘位移）技术，能够在不剥皮的情况下直接将导线压接到触点中，简化装配流程并降低人工错误。触头为铜合金基材，表面镀锡，兼顾导电性与耐腐蚀性；绝缘体材料满足 UL 94V-2 阻燃等级，适用于一般工业与消费类产品的安全需求。
四 电气与环境性能
凭借 5 A 的额定电流与 250 V 的额定电压，该组件适合中小功率信号与电源连接场景。设计的温度范围（-55 ℃ 至 +105 ℃）可满足多数室内及轻工业环境下的长期使用需求。镀锡触头在常见环境中具有良好接触稳定性与抗氧化能力。
五 安装与使用建议
- 使用与 MTA 100 系列匹配的压接/装配工具进行 IDC 压接，以确保接点完整且接触可靠。
- 在装配前确认所用导线类型与绝缘厚度符合 MTA IDC 规范，以免影响接触质量。
- 悬挂安装时注意线束支撑与应力释放，避免长期拉力或振动导致接触松动。
- 如需提高耐腐蚀或耐磨性，可在设计端考虑配合适当的封装或保护罩。
六 典型应用场景
适用于工业控制设备、通信设备、消费电子、家用电器、测试仪器以及任何需要标准 2.54 mm 间距快速线对板连接的场合，特别是在需要快速批量装配、现场维修或替换的应用中优势明显。
七 选型与兼容性提示
- 与同系列 MTA 100 的排母/插头配合使用以保证机械与电气性能。
- 若对耐温、阻燃或接触寿命有更高要求，可咨询原厂资料选择相应升级型号或不同镀层工艺。
- 订购时请确认完整料号与包装规格，以便满足生产节拍与库存管理需求。
八 小结
3-643814-4 为 TE Connectivity 提供的一款标准化、易装配的 4 位 IDC 线对板连接器，兼具可靠的电气性能与良好的装配效率，适合广泛的工业与民用电子连接需求。选用时注意与 MTA 100 系列配套的装配工具和线材规格，以确保长期稳定运行。

Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
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.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
