A1251WV-5P 产品概述

一、产品简介

A1251WV-5P 为 CJT(长江连接器)系列 1x5P 线对板直插针座,间距 P = 1.25mm,单排 5PIN。该产品采用直插(Through-hole)安装方式,适用于小间距线对板连接场合,面向信号/低功率传输、排线连接及紧凑型电子模块内配线需求。

二、主要特性

  • 插针结构:1x5P,排数:1,每排 PIN 数:5
  • 间距(Pitch):1.25mm,适合高密度布线
  • 额定电流:1A(单针),适合信号与小功率电源输送
  • 额定电压:125V(绝缘等级下工作参考)
  • 工作温度:-40℃ ~ +105℃
  • 触头材质:磷铜(高弹性、良好导电性)
  • 触头镀层:锡(良好可焊性与成本效益)
  • 塑料材质:PA46,阻燃等级 UL94V-0

三、技术参数(要点)

  • 产品型号:A1251WV-5P
  • 封装形式:插件(直插)
  • 总 PIN 数:5P
  • 电气:1A / 125V
  • 温度范围:-40℃ 至 +105℃
  • 材料:触头—磷铜,镀层—锡;绝缘体—PA46(UL94V-0)

四、适用场景

  • 消费电子:小型显示模组、手持设备内部信号连接
  • 工控与仪表:低电流传感器接口、通信模块连接
  • 通信设备:模块间信号对接、转接板
  • 汽车电子(非动力关键):车载信息娱乐、传感器信号线对板连接(需按环境与可靠性评估)

五、安装与焊接建议

  • 焊接方式:推荐波峰焊或手工焊接;锡镀层提高焊接性
  • PCB 孔径:根据插针外径与板厚选择合适过孔,保证插入顺畅且焊点可靠(建议与 PCB 工程师确认具体孔径)
  • 焊接温度与时间:遵循锡膏与设备规范,避免长时间过热以保护 PA46 塑料件
  • 机械固定:直插件在波峰焊前可使用夹持装置以防位移

六、选型与注意事项

  • 电流与电压:A1251WV-5P 适合信号与小电流场合;若需要更高电流或耐压,应选更大间距或更高额定器件
  • 接触可靠性:锡镀层抗氧化性不及金镀,长期暴露在腐蚀性环境下可能影响接触,必要时考虑金镀或加防护措施
  • 环境适配:工作温度覆盖常见工业级要求,但在高温、高湿、强化学介质环境应进行额外评估
  • 互换性:1.25mm 间距为常见细间距规格,选型时确认配套插座(线端侧)与定位方式匹配

七、包装与储存

  • 建议干燥、防潮保存,避免长期阳光直射与强酸碱环境
  • 出厂包装以防静电、防冲击为宜;直插件避免受力变形
  • 存储温度与湿度遵循一般电子元器件规范,长期储存前建议进行外观与电性检查

总结:A1251WV-5P 提供紧凑的 1.25mm 间距直插解决方案,适合低功率信号连接与高密度布局场景。其磷铜触头与锡镀层带来良好可焊性,PA46 塑料满足 UL94V-0 阻燃要求。在选型与应用时,应结合实际电气/环境需求与装配工艺进行评估。若需详细的尺寸图纸、PCB 布局建议或可靠性数据,可进一步提供以便给出更具体的工程支持。

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
