XL-DA2381SRBC 是成兴光(Xinglight)推出的一款高可靠性 3 位 7 段 LED 数码管,字符尺寸 0.28 英寸(约 7.1 mm),发光颜色为红色,采用共阴(共阴极)极性设计,封装为通孔 DIP,外形尺寸 22.5 × 10 mm。器件适用于多种显示场合,具有体积小、响应快、寿命长等优点,便于在多位数码显示、电表、仪器仪表及消费类电子中使用。
正向压降约为 2.0 V,发光强度 20 mcd 为规格件给出的典型值,实际亮度会随驱动电流、占空比与环境温度变化。器件额定耗散功率为 36 mW,系统设计时需注意单个段和整体的热平衡。常见驱动方式包括直接限流驱动与多路复用驱动;多位复用时应根据占空比调整驱动电流,以保证平均功耗和温升在安全范围内。
举例(计算限流电阻):若驱动电源为 5 V,目标单段电流取 10 mA,限流电阻 R ≈ (5 V − 2 V) / 10 mA = 300 Ω(仅作示例,实际请按数据手册及测试调整)。
XL-DA2381SRBC 采用标准 DIP 通孔封装,整体外形尺寸 22.5 × 10 mm,便于板上安装与替换。0.28 英寸的字符高度适合中小型面板和便携设备,在视距与功耗之间取得平衡。通孔引脚提供良好的机械固定和焊接可靠性。
产品由成兴光(Xinglight)品牌提供,适合需要标准通孔安装与稳定显示效果的项目。选购与大批量应用前建议向供应商索取数据手册、样品及可靠性测试报告,以便在具体应用中进行验证与参数确认。

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.
