A2508WR-4P 产品概述
一 概述
A2508WR-4P 为长江连接器（CJT）XA系列的一款 2.5mm 间距插针端子，采用 1×4P 布局并以弯插（弯脚）形式封装，专为通孔 PCB 连接而设计。其外观为米色塑料，结构紧凑，适合对空间和可靠性有较高要求的电子设备与工业控制场景。
二 主要性能参数
- 引脚结构：1×4P（单排，4 针）
- 间距：2.5mm（P=2.5mm）
- 安装方式：弯插（弯脚、通孔安装）
- 额定电流：3A（峰值和长期载流需按实际温升评估）
- 额定电压：250V
- 触头材质：黄铜（铜基体）
- 触头镀层：镀锡（提高焊接性与抗氧化性）
- 塑料材质：PA66，阻燃等级 UL94V-0
- 工作温度：-40℃ ~ +105℃
- 颜色：米色
三 结构与材料优势
- 黄铜触头保证了良好的导电性能和机械强度，适合频繁插拔或震动环境下稳定接触。
- 镀锡处理对焊接工艺友好，能降低氧化带来的接触不良风险。
- PA66 阻燃外壳在高温及火焰暴露下能提供更高的安全性，符合一般工业级要求。
- 弯插封装在通孔焊接后能提供更好的机械支撑，适合承受外力和插拔应力的场合。
四 典型应用场景
- 工业控制板、继电器模块、接口扩展板
- 家用电器控制主板、照明控制驱动板
- 通讯设备、仪器仪表的电源与信号连接
- 小型电源模块与外设接口连线
五 安装与使用建议
- PCB 设计时按 2.5mm 间距布线并预留合适通孔与焊盘，保证焊接可靠性与机械卡位配合。
- 推荐使用波峰或手工焊接，焊接温度与时间应控制在 PA66 和镀锡层允许范围内，避免过度加热导致塑料变形或触头退镀。
- 在 3A 载流长时间运行时，请评估系统整体温升并预留散热空间；高温环境下应考虑降载或加强散热。
- 存储时避免潮湿、高温与长期阳光直射；出货前建议进行焊接性与接触电阻抽样检验。
六 质量与选型提示
- 产品符合常见工业级规格，触头材质与阻燃等级适合绝大多数控制与接口应用。
- 选型时确认实际电流、电压、环境温度及机械应力要求，必要时可咨询供应商获取样品进行可靠性验证。
- 若需要更高电流或防腐蚀性能，可考虑更高镀层工艺或替代材质的产品型号。
A2508WR-4P 以其紧凑的 2.5mm 布局、可靠的材料与弯插结构，适用于多种通用与工业控制场合，是常见的 PCB 端子连接方案之一。

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.
