640456-3 产品概述
一、产品简介
640456-3 为 TE Connectivity（泰科电子）MTA 100 系列的垂直式 PCB 插针连接器，1×3P 布局，间距 2.54 mm（0.1 in），部分护套设计，直插（Through Hole - Solder）安装方式。该产品用于 wire-to-board 信号互连，兼顾可靠的电气性能与良好的机械强度，适合批量压接线束或手工焊接的常见电子设备应用。
二、主要特性
- 引脚数：3P，单排单排设计，间距 2.54 mm；
- 额定电流：5 A（单引脚额定），可满足一般低中功率信号/电源传输需求；
- 额定电压：250 V，适用于常见低压电路隔离；
- 触头材质：铜合金，确保电导率与机械弹性；
- 触头镀层：锡镀，改善焊接性与接触耐腐蚀性；
- 工作温度：-55 ℃ 至 +105 ℃，适应宽温度环境；
- 阻燃等级：塑料外壳符合 UL94V-0，提升安全性；
- 结构：部分护套（partial shroud），可提供引导与防误插功能；
- 安装方式：直插通孔，适合波峰或手工焊接工艺。
三、典型应用场景
- 工业控制与自动化设备的信号与低功率电源连接；
- 通信与网络设备内部线束连接；
- 仪器仪表、消费电子与测试治具的板对线连接；
- 原型开发与生产线中常见的 MTA 系列线对板互连场景。
四、设计与安装建议
- PCB 布局时预留 2.54 mm 间距的标准焊盘与通孔，具体孔径与焊盘尺寸建议参照 TE 官方数据手册以保证插针配合与焊接可靠性；
- 采用通孔焊接（波峰或手工）时，应控制焊接温度与时间，避免超温影响塑料件与镀层；
- 对于长时间承载靠近额定值的电流，建议在板上考虑散热与走线宽度，必要时增加铜箔面积或使用散热路径；
- 机械应力（插拔次数、振动）较大时，应在结构上做加固设计或选用更高可靠度的对接方案。
五、材料与可靠性
- 触头为高导电性铜合金并经锡镀处理，保证良好电接触和可焊性；
- 塑料外壳采用阻燃材料，耐高温，工作温度范围宽；
- 部分护套设计有助于插拔定位与防止误插，提高使用安全性与可靠性。
六、采购与技术资料
如需最终尺寸图、PCB 推荐封装、机械强度/插拔寿命等详细参数，请参阅 TE Connectivity 官方数据手册或联系授权分销商索取 640456-3 的详细资料与最新库存信息。选型时建议核对实物样品并进行目标环境的电气与环境测试验证。

Use the form for single models, category sourcing, and multi-line BOM requirements.
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.
