MOLEX 39288020是一款专为中载流、高压场景设计的直插式线对板针座,凭借紧凑结构、高可靠性与宽环境适配性,成为工业控制、电源模块等领域的常用连接组件。以下从核心特性、结构设计、电气性能等维度展开概述:
该产品属于MOLEX线对板连接系列,型号为39288020,明确为2P直插针座,插针布局采用2×1P结构(2排,每排1针),针距(相邻插针中心距)与行距(两排插针中心距)均为4.2mm,是一款小规格但高载流的插件式连接组件。
采用2排1针的简化布局,总PIN数2P,避免多余针脚占用PCB板空间,适合空间受限的小型设备;白色PA塑料外壳清晰易辨,便于装配定位与后期维护识别。
支持通孔焊接安装,适配常规PCB板生产工艺,无需特殊工装即可完成装配,降低生产复杂度;插件式结构确保插针与PCB板的机械连接牢固,减少虚焊、脱焊风险。
该针座的电气性能针对中载流、高压场景优化,核心参数如下:
采用PA(聚酰胺) 塑料,具备良好的耐温性、机械韧性与耐化学性,可承受焊接高温(260℃左右回流焊)与长期环境应力;
外壳阻燃等级达到UL94V-0(最高阻燃等级之一),在意外短路、过载等场景下可有效抑制火焰蔓延,符合工业安全标准;
黄铜触头+锡镀层的组合平衡了导电、焊接与耐腐需求,PA外壳的机械保护确保插针在插拔或振动场景下不易变形,经测试可满足数千次插拔循环。
基于其高载流、高压、宽温与阻燃特性,MOLEX 39288020适用于以下场景:
MOLEX作为全球领先的连接器制造商,拥有超过80年的行业经验,其产品严格遵循UL、VDE等国际安全标准,39288020继承了MOLEX的可靠性设计理念,批量生产中保持参数一致性,为客户提供稳定的连接解决方案。
以上概述覆盖了MOLEX 39288020的核心特性与应用价值,可帮助用户快速判断该产品是否适配其设计需求。

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.
