PZ254V-12-4P 排针产品概述

PZ254V-12-4P是兴飞电子(XFCN)推出的一款2.54mm间距双排方针插件排针,针对小型化设备的多路信号/电源连接需求设计,兼具标准兼容性与可靠性能,广泛适配消费电子、工业控制等领域。以下从核心参数、结构设计、性能优势、应用场景及安装注意事项展开概述。

一、产品核心参数与基本定位

该产品的核心参数围绕“标准间距+紧凑布局”展开,具体如下:

  • 引脚布局:双排2×2P(总4位引脚),行距2.54mm与排间距一致,适配多数双排排母;
  • 机械规格:间距2.54mm(行业通用标准,兼容90%以上PCB板焊盘设计),方针直径符合接触要求;配合针长度6mm(确保排母连接深度),端接针长度3mm(适配PCB焊接高度),塑高2.5mm(节省PCB空间);
  • 材料与环境:触头采用黄铜(导电/抗腐蚀),塑壳为黑色耐高温工程塑料;工作温度范围-40℃~+105℃,覆盖工业级与消费电子典型环境;
  • 安装方式:直插式(DIP),适合手工或自动焊接设备。

其定位为小型多路连接的通用型排针,既满足低电流信号传输(如传感器I/O),也可承载小功率电源(如5V/3.3V供电)。

二、结构设计特点

1. 方针接触提升稳定性

相比圆针,方针采用平面接触结构,接触面积较同直径圆针提升约30%,可有效降低接触电阻(典型值≤20mΩ),减少信号传输损耗,同时降低虚接风险,适合对信号稳定性要求较高的场景。

2. 紧凑塑壳适配小型化

塑高仅2.5mm,双排布局宽度与单排排针相近,可在有限PCB空间内实现4路并行连接,适配便携式设备(如智能手环、蓝牙耳机)、小型工业模块(如传感器节点)等对体积敏感的产品。

3. 标准间距兼容性强

2.54mm间距是电子连接领域的“通用基准”,PZ254V-12-4P可与绝大多数品牌的2.54mm排母、单排/双排针座直接配合,无需额外设计适配结构,降低研发成本。

三、材料与性能优势

1. 黄铜触头的双重优势

触头采用H62黄铜(含铜量≥60.5%),导电率达40%IACS以上,确保信号/电源传输低损耗;同时黄铜抗腐蚀性能优于纯铜,可在潮湿、轻度盐雾环境下长期使用(符合GB/T 2423.17盐雾测试基础要求)。

2. 宽温域环境适应性

工作温度范围-40℃~+105℃,覆盖:

  • 低温场景:户外设备(如低温地区环境监测传感器)、车载电子(冬季低温启动);
  • 高温场景:工业控制模块(夏季车间高温)、充电设备(电池充电温升)。

3. 塑壳机械可靠性

黑色塑壳采用PA66+GF(玻纤增强尼龙66),抗冲击强度≥80J/m,焊接时可承受260℃以下短期温度(符合回流焊/手工焊常规要求),不易出现塑壳变形、开裂问题。

四、典型应用场景

PZ254V-12-4P的4位双排布局,适合多路并行的低复杂度连接,具体场景包括:

  1. 消费电子:便携式设备电池接口(2路电源+2路信号)、智能音箱麦克风模块连接;
  2. 工业控制:小型PLC的I/O输入接口、温度传感器节点信号/电源连接;
  3. 车载周边:车载充电器内部PCB连接、行车记录仪电源/数据接口;
  4. 通信配件:路由器小型扩展模块(如WiFi天线接口)、交换机指示灯模块连接。

五、选型与安装注意事项

1. 选型匹配要点

  • 需求确认:需2×2P布局、方针、直插式、2.54mm间距;
  • 配合件:与排母配合时,确认排母针长(建议配合针6mm与排母接触深度≥4mm)、间距一致性;
  • 环境适配:若温度超出-40℃+105℃,需选择宽温型(如-55℃+125℃)替代型号。

2. 安装焊接注意

  • 焊接温度:手工焊建议烙铁温度350℃~380℃,焊接时间≤3秒/引脚;自动焊需符合塑壳耐温曲线;
  • 引脚处理:避免过度弯折端接针(弯折角度≤90°),焊接前确认引脚与PCB焊盘对齐;
  • 清洁:焊接后用酒精清洁焊盘残留助焊剂,避免腐蚀塑壳。

总结:PZ254V-12-4P以“标准间距+方针稳定+紧凑布局”为核心优势,适配多场景小型多路连接需求,是消费电子、工业控制等领域的高性价比选择。

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
