MOLEX 5023800400是一款1x4P、1.25mm间距的线对板/线对线胶壳,凭借紧凑尺寸、可靠锁扣及宽温适应性,成为小型电子设备连接方案的优选组件。以下从核心参数、设计特性、应用场景等维度展开概述。
该胶壳的关键参数清晰明确,可直接匹配具体应用需求:
紧凑化插孔布局
1.25mm的引脚间距是当前小型化电子设备的主流间距之一,单排4孔设计进一步缩小了整体尺寸,可显著节省PCB板空间,适配空间受限的产品(如便携式设备、微型传感器)。
带锁扣连接可靠性
内置锁扣结构是该胶壳的核心优势:插入对应端子后,锁扣可自动卡合,有效防止振动、冲击或外力拉扯导致的连接松脱,提升了动态环境下的电气连接稳定性(如车载、工业现场)。
高阻燃安全性能
UL94V-0阻燃等级意味着材料在燃烧测试中,火焰熄灭时间短(≤10秒)且无滴落物,可降低产品在火灾场景下的蔓延风险,满足消费电子、汽车等领域的安全规范要求。
耐温材料适配
采用耐高温工程塑料(如改性PBT或PA),确保在-40℃低温下无脆化、+105℃高温下无变形,覆盖了大多数户外、车载及工业应用的温度需求。
MOLEX 5023800400的设计特性使其适用于多领域的小型连接需求:
宽温环境适应性
-40℃~+105℃的工作温度范围,可同时覆盖北方冬季户外(低温)、车载发动机舱(高温)等极端场景,无需额外防护即可稳定工作。
可靠连接保障
锁扣结构+1.25mm间距的紧密配合,可减少端子与胶壳之间的间隙,降低接触电阻波动,确保信号传输的稳定性(尤其适合模拟信号或低功耗数字信号)。
品牌级质量可靠性
MOLEX作为全球知名连接器厂商,其产品经过严格的质量测试(如插拔寿命、振动测试),5023800400的插拔寿命通常可达数百次,满足产品全生命周期的使用需求。
环保合规性
产品符合RoHS 2.0、REACH等国际环保指令,无铅、无镉等有害物质,适配全球市场的环保要求。
匹配端子
需与MOLEX 50238系列压接端子配合使用(如型号502380000、502380001等),确保端子的线径范围(通常0.05~0.15mm²)与应用线缆匹配。
安装流程
注意事项
避免过度拉扯线缆(尤其是锁扣未完全卡合时),焊接板端连接器时温度不超过350℃(控制在3秒内),防止胶壳变形。
MOLEX 5023800400以紧凑尺寸、可靠锁扣、宽温适应性为核心优势,精准匹配小型电子设备的连接需求,是消费电子、汽车电子、工业控制等领域的高性价比连接组件。其符合多项安全与环保认证,可直接用于全球市场的产品设计中。

Use the form for single models, category sourcing, and multi-line BOM requirements.
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.
