A2508WV-2P是长江连接器(CJT)XA系列下的一款小型化线对板直插针座,专为紧凑空间内的可靠电气连接设计,核心规格为1×2P(单排2Pin)、间距2.5mm,广泛适配小家电、工控模块、消费电子等领域的低功率电路连接需求。
作为XA系列的基础型号,A2508WV-2P聚焦小体积、高可靠的线对板连接场景,基础参数清晰明确:
触头采用黄铜基材+锡镀层设计:黄铜具有优异的导电性能,可降低接触电阻;锡镀层则有效提升抗氧化能力,减少长期使用中的接触不良风险。额定3A电流与250V电压的组合,可稳定支撑小家电(如电饭煲、加湿器)的内部供电、工控模块(如小型PLC、传感器)的信号传输。
直插式结构便于PCB焊接,插针与塑料主体的配合稳固,可承受常规插拔操作(黄铜触头的耐磨特性可保障长期使用可靠性);2.5mm间距的紧凑设计,可节省PCB板空间,适配小型化设备的布局需求。
黄铜作为触头基材,导电率约为纯铜的78%,但机械强度更高,避免插针变形;表面锡镀层厚度符合行业标准,可有效防止氧化,确保接触电阻稳定(通常低于10mΩ)。
PA66(聚酰胺66)是工程塑料中的常用材质,具有高机械强度、耐冲击、耐油等特性,可承受焊接高温(短期260℃以下无变形);UL94V-0阻燃等级通过第三方认证,满足电子设备的安全规范要求。
直插式安装无需特殊工具,仅需常规波峰焊或手工焊接即可完成,生产效率高;1×2P的Pin数设计,可满足单路供电或简单信号传输的需求,避免冗余设计。
需确认对插端子为CJT XA系列同规格产品(如XA系列线端端子),确保Pin数、间距(2.5mm)完全一致,避免连接松动或接触不良。
手工焊接时,烙铁温度控制在260℃以下,焊接时间不超过3秒,避免塑料主体受热变形;波峰焊需设置合适的温度曲线,防止插针氧化。
产品需存储在常温(15℃~35℃)、干燥(相对湿度≤60%)的环境中,避免长期暴露在潮湿、腐蚀性气体(如硫化氢)中,防止触头镀层氧化。
A2508WV-2P以其紧凑体积、可靠性能与成本优势,成为小型电子设备线对板连接的常用选择,可满足多数低功率场景的连接需求。

Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
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.
