MF254V-11-04-0743是兴飞电子(XFCN)推出的单排直插圆孔排母,专为中小功率电路的信号/电源连接设计,核心参数清晰匹配主流应用需求:
该型号参数与同针距的插针/端子完全适配,可直接替代同类通用排母。
采用1x4P直线排列,4个插孔间距2.54mm,既保证连接密度,又避免多排结构的空间占用,适合小型化设备(如便携音箱、小型传感器模组)的内部紧凑布局。
相较于方孔/扁孔,圆孔插孔为圆柱状,与匹配的圆柱插针接触时接触面积更均匀,能有效降低接触电阻波动(减少信号衰减),同时插针插入/拔出时磨损更小,延长连接器寿命。
塑壳底部带插脚,可直接焊接于PCB焊盘,适配波峰焊、手工焊等成熟工艺;插脚长度适配常规1.6mm厚PCB,无需额外加工,焊接可靠性高。
塑壳高度仅3mm,在保证插孔深度(满足端子插入需求)的前提下,大幅降低连接器在PCB上的高度占用,适合对设备厚度有严格要求的场景(如智能手环、车载小型模组)。
该排母的电气性能满足中小功率电路的安全连接需求,核心指标经出厂测试符合行业标准:
工作温度覆盖**-40℃~+105℃**,可适应寒冷地区(如北方户外设备)、高温工业环境(如烤箱、高温车间)等极端温度,不会因温度变化导致塑壳变形、接触不良。
塑壳采用UL94V-0级阻燃工程塑料,遇明火快速自熄,降低电路起火蔓延风险;同时具备耐湿热性能,可在湿度≤90%RH的环境下长期稳定工作(符合GB/T 2423.3湿热试验要求)。
插件式结构与插脚焊接强度可靠,可承受10Hz~2000Hz振动频率、2g加速度冲击(符合GB/T 2423.10振动试验要求),适合工业控制、汽车电子等振动场景。
MF254V-11-04-0743凭借紧凑尺寸、宽温性能与稳定连接,广泛应用于以下领域:
MF254V-11-04-0743作为XFCN的高性价比排母,以紧凑尺寸、宽温性能、稳定连接为核心优势,适配多领域中小功率电路的连接需求,是小型化设备内部接口的优选方案。

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.
