DF13A-2P-1.25H(21)线对板针座产品概述
一、产品基本参数与规格
DF13A-2P-1.25H(21)是HRS（广濑） 推出的紧凑型线对板针座，专为小型化设备的信号/低功率电源传输设计，核心参数如下：
- 结构规格：单排2针（1x2P），总PIN数2，间距1.25mm（小间距紧凑型）；
- 安装方式：卧贴式SMD（表面贴装），无插件引脚，适配自动化贴片工艺；
- 电气性能：额定电流1A（AC/DC通用），触头材质为黄铜（导电性优异），表面镀锡（防氧化）；
- 环境适应性：工作温度范围-35℃至+85℃，满足工业级及消费电子的高低温场景需求；
- 封装形式：SMD封装，匹配1.25mm间距的贴片生产标准。
二、核心设计与材质优势
- 小间距省空间：1.25mm间距是目前消费电子、便携式设备的主流小间距规格，可大幅压缩PCB占用面积，助力设备实现轻薄化（如智能手环、蓝牙耳机等对体积敏感的产品）；
- 卧贴适配自动化：采用表面贴装技术，无需在PCB上开插件孔，可通过贴片机快速安装，提升生产效率，同时避免插件工艺中PIN针弯曲的不良风险；
- 稳定的触头性能：黄铜触头导电性好，表面镀锡可有效防止氧化，长期使用仍能保持可靠接触；1A额定电流覆盖一般低压信号（如I2C、SPI）及小功率电源（如3.7V锂电池输出）的传输需求；
- 宽温环境兼容：-35℃至+85℃的温度范围，覆盖了冬季户外使用的智能手表、工业控制的小型传感器模块等场景，可靠性有保障。
三、典型应用场景
因小间距、卧贴、高可靠性的特点，该针座广泛应用于以下领域：
- 便携式消费电子：智能手机内部传感器模块连接、智能手表电池与主板对接、蓝牙耳机充电触点连接；
- 小型工业模块：工业温湿度传感器信号输出对接、PLC辅助控制模块的电源/信号连接；
- 汽车电子低功率部件：车内氛围灯控制模块、车载USB接口内部连接（非高压大功率场景）；
- 智能家居设备：智能门锁指纹模块与主板连接、智能灯泡驱动板与灯珠板对接。
四、安装与使用注意事项
为保证产品性能及使用寿命，使用时需注意：
- 贴片精度控制：卧贴SMD需确保贴片机定位精度（建议±0.05mm以内），避免针座偏移导致焊接后接触不良；
- 焊接参数规范：焊接温度控制在260℃左右，单次焊接时间不超过3秒，防止高温损坏塑料壳体或镀层；
- 触头防护：安装前避免用手直接触碰触头（汗液易污染镀层导致氧化），对接时需对准针座与插头PIN针，防止插歪弯曲；
- 环境防护：虽具备宽温性能，但应避免长期暴露在高湿度（>90%RH）或腐蚀性气体中，必要时可配合密封胶防护。
总结
DF13A-2P-1.25H(21)作为HRS的紧凑型线对板针座，凭借小间距、卧贴安装、可靠触头及宽温适应性，成为小型化设备内部连接的优选方案，满足消费电子、工业、汽车等多领域的低功率信号/电源传输需求。

Use the form for single models, category sourcing, and multi-line BOM requirements.
Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
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.
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.
