MOLEX 501258000 PicoBlade系列胶壳端子产品概述

MOLEX 501258000是PicoBlade(MX 1.25)系列中的线端胶壳端子,针对2628AWG线规及0.5mm1mm绝缘外径的导线设计,具备小型化、高可靠性等特点,广泛适配空间受限的电子设备应用场景。

一、产品核心定位与系列背景

PicoBlade系列是MOLEX推出的1.25mm间距小型化连接器,主打高密度布线需求——相比传统2.0mm间距连接器,可节省约40%的PCB空间。501258000作为该系列的线端端子,核心定位为“适配常用小线规的压接式连接组件”,需配合同系列胶壳(如50125系列胶壳)使用,实现导线与PCB的可靠连接。

二、关键参数详解

2.1 电气参数

  • 额定电压:125V(AC/DC通用),满足多数低压电子设备(如消费电子、小型医疗设备)的电压需求;
  • 触头材质:磷青铜(C5191/C5210),具备高弹性、耐磨损特性,长期使用不易因插拔产生塑性变形;
  • 触头镀层:锡镀层(厚度≥1μm),兼具良好导电性与抗氧化性,可有效避免触头氧化导致的接触电阻增大。

2.2 机械参数

  • 线规适配:2628AWG(对应导线裸线直径0.1290.163mm),覆盖消费电子中常见的小线径导线;
  • 绝缘外径范围:0.5mm~1mm,适配不同绝缘层厚度的导线(如PVC、PE绝缘线);
  • 间距规格:1.25mm(PicoBlade系列标准间距),支持单排/双排布局,满足不同通道数需求。

三、适用场景与应用优势

3.1 典型应用场景

  • 消费电子:智能穿戴(手环、手表)、小型音频设备(蓝牙耳机、TWS充电盒);
  • 医疗设备:便携式监护仪、小型诊断仪器(空间受限,需高密度连接);
  • 汽车电子:车载辅助系统(如倒车雷达模块、氛围灯控制器);
  • 工业控制:小型传感器模块、PLC扩展卡(低功耗、小体积场景)。

3.2 核心应用优势

  1. 小型化优势:1.25mm间距大幅减少PCB占用空间,适配超薄/超小型设备;
  2. 连接可靠性:磷青铜触头+锡镀层组合,插拔寿命可达数千次(典型值≥5000次),接触电阻稳定(≤20mΩ);
  3. 组装便利性:压接式设计,无需焊接,可通过自动化压接设备快速组装,提升生产效率;
  4. 线规适配性:26~28AWG为市场常用线规,绝缘OD范围覆盖多数小线径导线,无需额外定制导线。

四、设计与可靠性特点

4.1 结构设计亮点

  • 压接端子结构:采用“双线压接”(绝缘压接+裸线压接),确保导线与端子的机械连接强度,避免导线脱落;
  • 触头接触设计:触头带有弹性凸起,插拔时可产生稳定的接触力,减少振动导致的接触不良;
  • 胶壳兼容性:可与MOLEX PicoBlade系列胶壳(如单排220pin、双排216pin)完美配合,支持锁扣式或无锁扣式连接。

4.2 可靠性验证

  • 环境适应性:可在-40℃~+85℃的温度范围内稳定工作,满足工业级与消费级设备的环境需求;
  • 抗振性能:通过振动测试(10~2000Hz,加速度1g),接触电阻变化率≤10%,适合移动设备或车载场景。

五、选型与配套建议

5.1 选型注意事项

  • 需确认导线参数:线规是否为2628AWG,绝缘外径是否在0.5mm1mm范围内;
  • 需匹配胶壳:根据通道数需求选择对应pin数的PicoBlade胶壳(如50125-0200对应2pin胶壳);
  • 需考虑电流需求:PicoBlade系列额定电流通常为0.5A/contact(26AWG),需确认应用场景的电流负载不超过该值。

5.2 配套组件推荐

  • 压接工具:MOLEX专用压接钳(如工具编号063819000),适配26~28AWG导线的压接;
  • 胶壳配件:如需防脱,可选择带锁扣的胶壳(如50125-0201);
  • 导线选择:推荐使用PVC绝缘的2628AWG导线,绝缘OD控制在0.60.9mm之间(中间值适配性最佳)。

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
