A2543WV-5P 产品概述

一、产品简介

A2543WV-5P 是 CJT(长江连接器)推出的一款标准 2.54mm 间距的线对板插针座,单排 1x5P 直插结构,适用于常见的通用电子连接需求。该器件以可靠的电气性能与工业级耐温、阻燃材料为基础,适合消费电子、通信设备、仪器仪表及工业控制板级连接使用。

二、主要参数

  • 插针结构:1x5P(单排,5 针)
  • 间距(Pitch):2.54 mm
  • 安装方式:直插(插件 / Through-hole)
  • 额定电流:4 A(单针额定)
  • 额定电压:250 V
  • 工作温度:-40 ℃ ~ +105 ℃
  • 总 PIN 数:5P;排数:1;每排 PIN 数:5

三、结构与材质

  • 触头材料:黄铜(Brass)
  • 触头镀层:镀锡(Tin plating),提高焊接性与抗氧化性能
  • 塑料材质:PA66,符合 UL94V-0 阻燃等级,保证高温下的机械稳定性与安全性
    该结构为直插式针脚,便于通过波峰/手工焊接固定于 PCB,外形紧凑,便于批量装配。

四、电气与环境性能

A2543WV-5P 单针额定 4A、250V,满足常见信号与低功率电源连接需求。触头采用黄铜+镀锡组合,既保证良好的导电性,又兼顾成本与焊接可靠性。工作温度范围 -40℃ 至 +105℃,适应多种室温和轻工业环境;PA66(UL94V-0)外壳提高了耐热与阻燃等级,提升长期使用可靠性。

五、安装与使用建议

  • 安装方式为直插通孔,建议按厂方提供的 PCB 封装图纸设计焊盘与过孔尺寸,以获得最佳可靠性与装配效率。
  • 适用于普通波峰焊、选择性焊或手工焊接工艺;焊接温度和时间应控制在 PA66 与镀锡触点允许范围内,避免长时间高温暴露。
  • 建议在装配与使用中注意防止强机械冲击和过度弯曲,以延长连接寿命。

六、典型应用场景

适用于主板与线缆、模块与主板之间的信号与电源连接场景,包括但不限于:工业控制器、消费类电子、通信设备、测试仪器、嵌入式开发板及各种模块化系统的板对线连接。

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
