PM254V-12-04-H85是XFCN(兴飞)品牌推出的一款双排直插式方孔排母,采用行业通用2.54mm间距设计,聚焦中小功率电路的稳定连接需求,兼具紧凑结构与高可靠性,适配多种电子设备的内部连接场景。
该排母的核心参数明确了应用边界:
其基本定位为小型化通用连接组件,避免大尺寸排母的空间浪费,适配对紧凑性、电流承载有要求的电路设计。
双排2×2P布局,既满足多信号/电源并行传输,又将PCB占用面积控制在约10mm×10mm;2.54mm中心距与行距完全对齐,可直接对接同规格排针,无需额外调整PCB布局,降低设计成本。
区别于常规圆孔,方孔结构具备三大优势:
直插式插件需焊接于PCB穿孔,相比贴片排母连接强度更高,适合振动、冲击场景;支持波峰焊/手工焊,适配不同生产工艺。
该排母满足中小功率电路核心需求:
工作温度覆盖**-40℃~+105℃**,适配:
塑壳采用耐高温工程塑料(PA66/PBT),耐冲击抗老化;导电部分为优质黄铜,表面处理符合RoHS标准,插拔寿命≥500次,满足设备全生命周期需求。
该排母适配多领域场景:
XFCN(兴飞)作为国内连接器专业制造商,该产品具备:
综上,PM254V-12-04-H85排母以紧凑结构、可靠性能与通用兼容性,成为中小功率电路连接的优选组件,覆盖消费电子到工业控制多领域。

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.
