XL-257UGC-L(品牌:Xinglight / 成兴光)是一款直插(插件)高亮绿光发光二极管,封装常见为5mm直径(L = 5 mm)长脚型,型号中常见描述“257m 白发翠绿长脚”用于区分外观与脚长样式。二极管为独立二极管配置,便于单点指示和逐个驱动控制。
选购时建议向供应商确认批次(binning)和出厂测试数据,尤其是电流-亮度一致性与波长分布,以满足对颜色或亮度一致性要求较高的用途。向品牌(Xinglight / 成兴光)或其授权经销商索取技术资料和样品进行实测验证,可降低项目风险。
总结:XL-257UGC-L 为一款面向指示与显示用途的高亮翠绿色 5mm 插件 LED,具有较窄发光角与稳定的光电参数,适合需要方向性强且颜色识别度高的指示应用。设计时按额定 If=20 mA 驱动并留有热、电裕度,可获得可靠的长期运行表现。

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.
