TE Connectivity 640456-5 产品概述

一、概述与定位

TE Connectivity 型号 640456-5 是一款经典的直插式 PCB 排针(1×5P,间距 2.54 mm),属于 MTA‑100 家族的线对板连接器解决方案。该产品为通孔(through‑hole)插件结构,适用于需要可靠机械支撑与可拆接线端子的电路板连接场景,可选带护罩(部分带护罩)以改善插拔导向与防护性能。品牌为 TE Connectivity(泰科电子),适合通用电子设备、控制板与工业接口应用。

二、主要电气与环境参数

  • 排数/针数:1 排 × 5 针(总 PIN 数 5P)
  • 间距(Pitch):2.54 mm [.1 in]
  • 额定电流:5 A(单针额定)
  • 额定电压:250 V
  • 工作温度范围:-55 ℃ 至 +105 ℃
  • 触头材质:铜合金,触头镀层为锡(Sn)
    上述参数保证了在中等电流与中等电压场合的可靠传导与长时间工作稳定性。

三、结构与材料

  • 安装方式:直插(通孔焊接),插件型封装(P = 2.54 mm)
  • 塑料材质:PBT(聚对苯二甲酸丁二醇酯),阻燃等级 UL94 V‑0
  • 触点处理:锡镀层,便于波峰/手工焊接并减小接触电阻与氧化
  • 尺寸参考:X轴(板上底边长度/间距线)约 12.7 mm;Y轴(板上底边宽度)约 5.71 mm
    该结构为通用 PCB 排针常见形式,既满足机械强度,又便于批量化焊接工艺。

四、PCB 布局与安装建议

  • 布局:按 2.54 mm 间距布置 5 个通孔,外边距应兼顾 12.7 mm 的板边参考尺寸以方便对齐与固定。
  • 焊接:推荐使用波峰焊或选择合适的手工焊工艺,注意控制焊接温度与时间以保护 PBT 塑料件。
  • 机械加固:对于频繁插拔或承受力矩较大的场合,可在设计板上增加固定孔或采用带护罩型号以提高导向与牢固性。
  • 配套连接:兼容 MTA‑100 系列线端与相应插接端子,便于线束快速化连接与维护。

五、典型应用场景

  • 工业控制板与继电器模块的线对板接口
  • 消费电子与通信设备中的信号/电源分配
  • 电力与电池管理系统中低压电流连接(在额定范围内)
  • 原型设计与教研平台中常用的 2.54 mm 排针接口

六、选型与注意事项

  • 电流/电压裕度:额定为 5 A/250 V,在设计时应考虑最大工作电流与环境散热,必要时选用更高额定的连接器或并联触点分担电流。
  • 插拔寿命与接触可靠性:锡镀层对抗氧化能力有限,长时间多次插拔环境建议选择具有耐久性更高的镀层或定期维护。
  • 温度与焊接相容性:PBT UL94V‑0 有良好的阻燃与温度耐受性,但波峰焊与回流工艺参数需按 TE 的规范执行以避免塑料变形。
  • 兼容性确认:在使用前确认配套线端(若使用 MTA‑100 系列端子)与插针间的匹配性,避免尺寸或导向不一致导致接触不良。

总结:640456-5 是一款成熟、通用且施工方便的 1×5 直插式 2.54 mm 排针,适合需要稳固通孔焊接与常规电流承载能力的线对板连接场合。购买与应用时建议参考 TE Connectivity 的产品资料与 PCB 尺寸图以保证最佳匹配与可靠性。

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
