RN1403,LF(T) 为东芝(TOSHIBA)生产的一款小功率 NPN 晶体管,封装为 TO-236-MOD(常见的 SOT-23 小型贴片封装)。器件设计用于低电流、低/中电压的小信号放大与开关场合,具有50V 的集-射极击穿电压(Vceo)、100mA 的最大集电极电流(Ic)以及 200mW 的额定耗散功率(Pd),适合在空间受限且需表面贴装的消费电子与工业控制电路中使用。
在选型时,若需替代器件,应对比 Vceo、Ic、Pd、封装与直流放大系数等关键参数。常见小信号 NPN 器件(SOT-23 封装)可作为参考,但需核对击穿电压与功耗是否匹配。若电流或功耗要求较高,应选用更大功率或更高电流等级的封装型号。
如需进一步的电气特性(直流增益 hFE、饱和压降、频率响应等)或热特性(结到环境热阻及降额曲线),建议查阅东芝 RN1403 的原厂数据手册或联系供应商以获取完整规格与应用说明。

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.
