Molex 0039281023 Mini-Fit Jr 系列连接器产品概述

Molex 0039281023是Mini-Fit Jr 5566系列下的板至电缆/导线连接器,作为Molex成熟的通用型连接方案,其设计兼顾可靠性与适配性,广泛应用于工业、电信及通用电子设备领域。

一、产品定位与系列背景

Mini-Fit Jr系列是Molex针对中小功率连接需求开发的经典产品线,以紧凑结构、稳定性能为核心特点。0039281023属于该系列的公形引脚接头,采用散装包装(适合小批量原型或灵活采购),零件状态为有源(可正常供应),基本产品编号关联003928,是该系列下2位规格的标准型号。

二、核心参数与结构设计

2.1 针脚与排距

该连接器为2位(2排)设计,配接排距为0.165英寸(4.20mm),满足小空间内的连接需求;所有针位均加载,无需额外配置空针,降低装配复杂度。

2.2 护罩与遮蔽

配备4墙遮蔽护罩,可有效减少电磁干扰(EMI),提升信号传输稳定性,尤其适配电信等对EMI敏感的场景;护罩结构同时增强针脚保护,降低碰撞损坏风险。

三、端接与安装特性

3.1 安装方式

采用通孔(Through-Hole)安装,适配标准PCB板的通孔焊接工艺,连接可靠性高,适合工业设备的长期稳定运行;绝缘高度为0.504英寸(12.80mm),可兼容多数PCB板的厚度与布局空间。

3.2 端接与紧固

端接方式为焊接,触头柱长0.138英寸(3.50mm),保证焊接时的接触面积与强度;紧固类型为锁销滑道,可与配接的母形连接器实现可靠锁合,防止振动环境下的松脱(如工业自动化设备)。

四、材料与可靠性

4.1 触头材料与镀层

触头采用黄铜材质,兼具良好的导电性与机械强度;配接端与柱端均镀锡,镀层厚度约35µin(0.90µm),锡镀层优势在于焊接性优异、抗氧化性强,可降低长期使用中的接触电阻变化。

4.2 绝缘材料

绝缘部分采用聚酰胺(PA66,尼龙6/6),天然颜色,材料可燃性等级为UL94 V-2,满足基本阻燃安全要求;PA66耐温范围广(-40℃至100℃左右),耐化学腐蚀性能良好,适合工业环境的复杂工况。

五、应用场景适配

0039281023的设计特性使其适配多类场景:

  • 工业领域:工业控制设备(如PLC模块、传感器连接)、小型自动化设备的板至线连接;
  • 电信领域:基站辅助模块、通信终端的小功率信号/电源连接;
  • 通用电子:消费电子原型开发、小型仪器仪表的内部连接。

其2位规格适合小功率传输需求(如低电压直流电源、数字信号),紧凑结构可节省设备内部空间。

六、选型与兼容性

作为Mini-Fit Jr 5566系列的子型号,0039281023可与同系列同排距(4.20mm)的母形连接器配接(需参考Mini-Fit Jr系列选型手册确认对应母头型号);散装包装支持灵活采购,适合小批量生产或原型验证,有源状态确保供应稳定性。

整体而言,Molex 0039281023以紧凑设计、可靠连接与广泛适配性,成为中小功率板线连接的实用选择,兼顾性能与成本平衡,适合多行业的标准连接需求。

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
