MOLEX线对板针座(1x4P 1.5mm卧贴SMD)产品概述

一、产品核心定位与基础参数

本产品为MOLEX品牌旗下标准化线对板连接组件,针对小间距、高密度电子设备的信号/低功率电流传输需求设计,采用单排4PIN卧贴式SMD封装,是小型化电子系统中常用的高可靠性连接方案。

核心基础参数汇总:

  • 插针结构:1排×4PIN(1x4P紧凑布局)
  • 间距规格:1.5mm(引脚中心距,比常规2.54mm缩小40%)
  • 安装方式:卧贴式表面贴装(SMD,无通孔占用空间)
  • 电气参数:额定电流2.5A/额定电压250V
  • 环境适配:工作温度-55℃~+105℃(宽温覆盖)
  • 材质工艺:触头黄铜+锡镀层,外壳UL94V-0阻燃,外观米色

二、关键性能指标解析

1. 电气性能适配中低功率场景

2.5A/250V的电气参数,可稳定支持信号传输+低功率供电需求——例如小型传感器模块、微型电机控制、LED驱动电路等场景,无需额外降额即可长期工作。锡镀层触头兼具良好焊接性与防氧化能力,降低接触电阻波动风险。

2. 宽温与阻燃的安全设计

  • 温度范围覆盖-55℃至+105℃,适配工业级/汽车级低温/高温场景(如车载辅助系统、户外监测设备);
  • 外壳UL94V-0阻燃,遇明火快速自熄,避免电路起火扩散,符合电子设备安全规范。

3. 小间距高密度布局优势

1.5mm间距结合卧贴SMD封装(引脚平行于PCB表面),可显著降低PCB占用面积,适合便携式设备、小型化模块(如智能手环配件、微型PLC)的紧凑布局需求。

三、设计与工艺特点

1. 卧贴SMD适配自动化生产

无需钻孔,可通过SMT贴片机直接贴装焊接,提升生产效率;避免通孔焊接的“立碑”“桥连”缺陷,降低返工成本。

2. 黄铜触头的可靠性设计

触头采用黄铜材质(导电率高、机械强度适中),表面锡镀层厚度符合行业标准——既提升焊接牢固度,又防止触头氧化,支持数百次插拔循环(常规场景下寿命≥5年)。

3. 米色外观的兼容性与识别性

米色外壳为行业通用识别色,便于生产中快速区分规格;产品尺寸符合MOLEX标准化接口,可与同系列1.5mm间距线端连接器完美匹配,无需额外适配。

四、典型应用场景

1. 消费电子领域

  • 便携式设备:智能手环/手表充电接口、蓝牙耳机充电盒内部连接;
  • 小型家电:智能插座、迷你加湿器控制模块连接。

2. 工业控制领域

  • 小型传感器:温度/湿度传感器与PLC的信号连接;
  • 微型执行器:小型电磁阀、微型电机的供电/控制连接。

3. 汽车电子领域

  • 车载辅助系统:倒车雷达传感器、胎压监测模块内部连接(适配车载温区);
  • 低功率设备:车载充电器、行车记录仪内部组件连接。

4. 医疗设备领域

  • 小型监护仪:便携式血氧仪、体温计的内部信号连接(符合阻燃安全要求)。

五、选型与安装注意事项

  1. PCB布局适配:确认焊盘尺寸与1.5mm间距、卧贴引脚规格匹配,避免焊接偏移;
  2. 焊接工艺:回流焊温度控制在220℃以内(锡镀层熔点上限),防止触头变形;
  3. 插拔规范:轴向受力插拔,避免过度弯折线端,延长针座寿命;
  4. 环境验证:极端温区(如-55℃)应用前,需通过温循测试确认可靠性。

六、合规与可靠性认证

本产品符合多项行业标准:

  • 阻燃认证:UL94V-0(北美安全标准);
  • 环保认证:RoHS 2.0(无铅、无有害物质);
  • 电气安全:IEC 60950-1(信息技术设备安全)。

通过MOLEX内部可靠性测试(温循、插拔、振动),可确保典型场景下稳定工作5年以上。

本产品以紧凑设计、宽温适配、高可靠性为核心优势,是小型化电子系统中替代传统大间距针座的优选方案。

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
