MOLEX 39301080是一款专为中功率传输场景设计的工业级线对板针座,属于MOLEX标准连接器系列。其核心规格清晰明确:采用2排×4针(2x4P) 插针布局,针脚间距(Pitch)为4.2mm,安装方式为弯插式(针脚垂直于塑料基座平面),总针数8P,行距与针脚间距一致(4.2mm)。作为MOLEX的成熟产品,该针座以稳定的电气性能和可靠的机械结构,适配各类需要中高压、中电流传输的设备。
该针座的电气参数针对性满足中功率场景需求,无需额外降额即可稳定运行:
触头采用黄铜(铜合金) 材质,兼具优异导电率(约40% IACS)和机械强度;表面镀纯锡,作用是:
基座选用PA66(聚酰胺66) 工程塑料,核心优势:
39301080采用插件式(Through-Hole) 安装,需将针脚插入PCB通孔后通过波峰焊固定。弯插设计的优势:
除工作温度范围外,PA66基座的耐湿性能(吸水率≤2.5%)可适应湿度变化较大的场景(如户外充电桩、沿海工业设备);黄铜触头的耐腐蚀性(锡镀层)可抵抗轻微盐雾侵蚀,进一步拓展应用边界。
39301080的参数与结构使其适配多领域:
总结:MOLEX 39301080以中功率传输为核心设计,兼顾电气稳定性、机械可靠性与环境适应性,是工业、新能源等领域的高性价比线对板连接方案。

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.
