A2547WR-4P 产品概述

一、概述

A2547WR-4P 为 CJT(长江连接器)系列标准 2.54mm 间距弯插排针,1×4P 结构,专为紧凑型电路板连接设计。该件适用于多种电子设备的信号与低功率供电连接,结合优良的材料与可靠的电气性能,应用广泛且可靠性高。标准化尺寸便于与通用 2.54mm 插座、线束及测试夹具互换。

二、主要技术参数

  • 插针结构:1×4P(单排 4 针)
  • 间距:2.54mm(P=2.54mm)
  • 安装方式:弯插(右角/弯脚式通孔安装)
  • 总 PIN 数:4P;排数:1;每排 PIN 数:4
  • 额定电流:3A(单针额定)
  • 额定电压:250V
  • 触头材质:黄铜;触头镀层:金(接触面金镀,提高耐磨和接触可靠性)
  • 塑料材质:PBT,阻燃等级 UL94V-0
  • 工作温度:-40℃ ~ +105℃
  • Z 轴(板上高度):3.51mm

三、产品特点

  • 高可靠接触:金镀触点控制接触阻抗,适合频繁插拔场景。
  • 良好机械强度:黄铜基体搭配 PBT 塑料座,耐振动、耐冲击。
  • 阻燃与耐温:PBT(UL94V-0)材料及宽工作温度范围,适应工业级环境。
  • 标准化接口:2.54mm 间距便于与常见公/母端子、线束及面板配合,设计与维护成本低。

四、典型应用场景

  • 工业控制板、嵌入式单板连接
  • 通信设备与测试治具接口
  • 消费电子、家电内部信号/电源互连
  • 小型电源模块、扩展卡互连

五、安装与使用建议

  • PCB 开孔:建议根据 PCB 加工工艺选择合适孔径(通常 0.9–1.1mm 区间),具体以样品测量或厂方数据为准。
  • 焊接工艺:支持波峰焊与手工焊接;焊接参数应控制在塑料与镀层耐温范围内,避免长时间高温浸泡以保护 PBT 塑料及电镀层。
  • 焊接清洗:尽量选用对金镀触点无腐蚀的清洗剂,避免影响接触可靠性。
  • 插拔与机械应力:设计时预留足够的机械支撑及应力分散结构,防止频繁插拔时对焊点或塑料座产生应力集中。

六、品质与采购

  • 品牌:CJT(长江连接器)
  • 型号:A2547WR-4P
  • 环保:常规为无铅/符合 RoHS 要求(如需检测报告,请向供应商确认)。
  • 包装与交期:可按需求提供散装或托盘包装,具体交期与最小订购量请联系供应商或代理商确认。

如需完整机械尺寸图、推荐 PCB 尺寸、3D 模型或样品验证(包括耐久性与接触阻抗测试数据),建议索取厂方数据手册或样品进行评估。

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
