EVPAA202K 产品概述
EVPAA202K 为松下（PANASONIC）推出的一款低剖面表面贴装轻触开关，顶部操作、矩形按钮设计，面向消费电子和信号控制类产品的微动开关需求。该器件以紧凑尺寸、稳定手感和长寿命为主要卖点，适用于体积受限、要求可靠触发的场合。
一 主要特性
- 单刀单掷（SPST）结构，顶部矩形按键，便于按压定位与面板配合；
- 触发力约1.6N（约160 gf），提供明确的机械反馈；
- 表面安装（SMD）形式，适配自动贴装与回流焊工艺；
- 额定电压15V DC，触点允许电流20mA，适用于信号级开关应用。
二 电气与机械参数
- 接触电流：20 mA；
- 额定电压：15 VDC；
- 操作力：160 gf（约1.6 N）；
- 使用寿命：200,000 次（典型）；
- 工作温度范围：-40℃～+85℃。
上述指标表明本产品更适合低电压、低电流的信号切换，非用于大电流或高压负载。
三 尺寸与封装
- 开关体积：长3.5 mm × 宽2.9 mm × 高1.7 mm；
- 封装：SMD-4P（四引脚），引脚样式为 J 型引脚，利于焊点成形与可靠性；
- 矩形顶部按键便于与面板开孔或贴合按键帽集成，适合平面化设计需求。
四 典型应用场景
- 手持设备与遥控器的功能按键；
- 工业与医疗仪器的信号选择和菜单确认键；
- 家用电器与智能家居控制面板；
- 物联网终端及便携式测量设备中作为低功耗信号输入。
五 安装与可靠性建议
- 推荐采用标准回流焊工艺，遵循松下或行业通用的回流温度曲线以避免过热；
- PCB 焊盘布局应匹配 J 型引脚几何，保证焊锡侧向支撑与机械应力释放；
- 贴装与回流后建议做功能测试与寿命验证；在清洗时选择对有机覆盖与弹簧结构安全的清洗剂，避免强烈振动或机械冲击；
- 运输与存储期间注意防潮防静电（MSL 及 ESD 管控），以确保焊接可靠性与触点性能。
六 选型与替代建议
若应用仅为信号检测且要求低剖面、长寿命与稳定触感，EVPAA202K 为合适选择。若需要更高电流或更高耐压，应考虑更大规格或额定值更高的开关。同时在对触感力值有严格要求时，可与供应商确认力-行程曲线与操作行程参数以匹配最终产品的人机工程设计。
总结：EVPAA202K 以小体积、表贴兼容性与稳定机械手感为优势，适合各类需要可靠、低功耗信号开关的消费及工业电子产品。

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.
