PM254V-12-08-H85排母产品概述

PM254V-12-08-H85是XFCN(兴飞)推出的一款双排直插式方孔排母,以2.54mm国际通用间距为核心设计,聚焦中小功率信号与电源的板间稳定连接,广泛适配工业控制、消费电子、通信设备等场景。以下从核心定位、性能参数、结构设计等维度展开详细概述:

一、产品核心定位与典型应用场景

该排母定位于高兼容性、宽温适应性的通用板间连接器,针对需要稳定传输中小功率信号/电源的场景优化:

  • 工业控制领域:PLC扩展模块、传感器接口板、机床控制柜的板间连接(满足-40℃~105℃宽温需求);
  • 消费电子领域:小家电控制板(咖啡机、加湿器)、智能家居设备的内部模块连接;
  • 通信设备领域:小型交换机、路由器的内部信号传输;
  • 汽车电子周边:车载音响、行车记录仪的辅助控制板连接(宽温适配车载环境变化)。

二、关键电气性能参数解析

核心参数直接决定产品适用范围,具体如下:

  1. 额定电流3A:可稳定传输5V/12V供电、传感器模拟信号等中小功率电流,满足多数民用与工业设备需求;
  2. 额定电压250V:符合我国低压电气安全标准,避免高压击穿风险,适配常规低压设备;
  3. 工作温度-40℃~+105℃:覆盖消费级(0~70℃)与部分工业级场景,可应对北方户外设备低温、工业控制柜高温的长期工作;
  4. 低接触电阻:方孔结构带来典型值≤20mΩ的接触电阻,减少信号衰减与发热。

三、机械结构设计特点

结构设计兼顾兼容性、可靠性与安装便利性:

  1. 孔位与间距:2x4P(双排4列)布局,间距2.54mm(国际通用标准),行距2.54mm(双排紧凑布局),兼容市场绝大多数2.54mm排针;
  2. 方孔插孔:区别于普通圆孔,接触面积更大,插拔时不易变形,长期使用后接触可靠性更高;
  3. 直插安装:插件式焊接到PCB板,机械强度高,抗振动性能优于贴片式,适合汽车、工业设备等振动场景;
  4. 塑高8.5mm:合理高度既避免增加设备厚度,又防止焊锡爬锡过高影响接触;
  5. 顶部插孔:垂直方向适配板对板连接,布局更简洁。

四、环境适应性与可靠性表现

XFCN品控确保产品在复杂环境下稳定工作:

  • 温度稳定性:-40℃无脆化、无应力裂纹;+105℃无软化变形、无加速氧化;
  • 耐湿性能:符合IEC 60068-2-60湿热试验(40℃/93%RH,96小时),避免潮湿接触不良;
  • 插拔寿命:额定插拔次数≥100次,满足常规设备维护需求;
  • 环保认证:通过RoHS、REACH认证,无有害物质,符合欧盟出口标准。

五、品牌与封装优势

  1. 品牌保障:XFCN是国内连接器知名厂商,专注研发生产10余年,质量稳定、交货周期短,适合批量采购;
  2. 标准封装:插件式2.54mm间距封装,PCB无需特殊定制,研发成本低;替代型号丰富,供应链风险低。

六、选型匹配与注意事项

  1. 排针匹配:需选2x4P、2.54mm间距、直插排针,确保完全兼容;
  2. 焊接规范:建议波峰焊(240~260℃,≤3秒),避免高温损坏塑料;
  3. 负载限制:禁止超3A额定电流,否则过热缩短寿命;
  4. 插拔操作:垂直插拔,避免倾斜变形,影响后续连接。

综上,PM254V-12-08-H85以标准间距、方孔可靠性、宽温适应性为核心优势,是中小功率板间连接的高性价比选择,适配多领域通用场景。

BOM matching & alternatives

BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.

Electronic component sourcing availability dashboard with ESD-protected samples

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.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
