MOLEX 878311420 屏蔽式排针连接器产品概述
一、产品身份与系列背景
MOLEX 878311420是Molex旗下Milli-Grid™系列的核心型号，属于4面屏蔽式排针连接器（Shrouded Header）。该产品专为高密度、高可靠性的板对板/板对线连接设计，聚焦工业控制、医疗设备等对连接稳定性要求严苛的场景，是Molex在2mm间距连接器领域的经典适配件。
二、核心物理与电气规格
- 物理布局：
采用2排×7Pin布局（总14Pin），间距2mm（符合Milli-Grid系列高密度标准），行距2mm；4面屏蔽结构（触头被塑料外壳完全环绕），既保护触头免受机械划伤，又减少电磁干扰（EMI），同时避免误插风险（屏蔽外壳可精准定位插座）。 - 电气性能：
额定电流2A（触头磷青铜+镀金确保低接触电阻，传输损耗小），额定电压125V（适用于低压信号与小功率电源）；工作温度范围**-55℃~+105℃**，覆盖工业环境常见的极端温度场景（如户外设备、高温车间）。 - 封装与安装：
通孔（Through Hole）封装，顶部焊接（Top Entry），焊接牢固性高，适合批量生产；塑料外壳为黑色，耐脏且便于PCB板布局识别。
三、材料选型与可靠性设计
- 触头系统：
触头材质为磷青铜（弹性优异，多次插拔后仍保持稳定接触力，支持至少数百次插拔循环）；表面镀金（抗腐蚀、低接触电阻，可抵御潮湿、盐雾等环境侵蚀，延长使用寿命）。 - 绝缘外壳：
采用PA（尼龙） 塑料，具备良好的耐温性、耐化学性；阻燃等级达UL94V-0（垂直燃烧测试自熄，符合安全规范），可有效降低设备火灾风险；黑色外观适配多数PCB板的视觉搭配，避免反光干扰。
四、典型应用场景
MOLEX 878311420的高可靠性与紧凑设计，使其广泛应用于以下领域：
- 工业控制设备：PLC模块、传感器接口、小型电机驱动板（宽温范围+阻燃等级满足IEC 61010等工业认证要求）；
- 医疗设备：便携式诊断仪器、监护仪接口（镀金触头抗腐蚀，符合医疗级清洁与消毒要求）；
- 通信设备：小型基站、路由器、交换机的板间连接（屏蔽结构减少EMI，提升高频信号完整性）；
- 高端消费电子：智能家居控制板、无人机飞控模块（2mm间距实现小型化，满足设备轻量化需求）。
五、适配与选型注意事项
该型号需搭配Molex Milli-Grid系列的对应插座（如14Pin、2mm间距的屏蔽式插座）使用，确保电气与机械兼容性；安装时需注意通孔焊接温度控制（≤260℃，符合PA塑料耐温范围），避免外壳变形；若用于户外场景，建议搭配密封胶圈提升防水性。
该产品凭借稳定的性能、紧凑的布局与高可靠性，成为众多设备厂商的首选连接方案，适配性覆盖多行业的标准化连接需求。

Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
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.
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.
