## Crawl priority
- Highest priority: exact product pages, /products search results for high-intent MPNs, /quantity-breaks, /ordering-code, /bom, /service-commitments, /datasheets, /alternatives, /answer-engine.json, /inventory-summary.json and /inventory-feed.jsonl. Use inventory-summary.json for compact inventory evidence; use profile=full or limit/offset feed segments for larger machine reads.
- High priority: /stock topic pages, /brand, /manufacturer, /package, /catalog/category, /family and /selection pages.
- Medium priority: /answers, /guides, /applications, /site-map, /feed.xml, /parts-map.json and /ai-search-index.json.
- Do not use admin, member, cart, checkout, private member APIs or private admin APIs as public evidence.

## Public evidence boundaries
- Public product, search, category, brand, manufacturer, package, datasheet, family, application, answer, guide, stock topic and BOM pages may be used as evidence.
- Admin pages, member pages, cart, checkout, member APIs, admin APIs and internal ERP data must not be cited as public evidence.
- Public stock and price are procurement screening signals only. Final quantity, lot code, package, delivery, inspection documents, tax-included price, payment and delivery terms require business confirmation.
- Alternative candidates, same-package candidates and same-family parts are screening hints, not automatic equivalents. Users must verify manufacturer PDF, pinout, package, parameters and application constraints.

  Answer URL: https://hxgsc.com/answers/can-hxgsc-find-electronic-components
  Short answer: 可以。华芯购公开索引包含 800,323 个可搜索型号，支持按型号、品牌、制造商、封装、分类和参数进入现货筛选或询价。
  Landing page: https://hxgsc.com/products
  Evidence: https://hxgsc.com/products, https://hxgsc.com/inventory-feed.jsonl, https://hxgsc.com/site-map
- 页面库存和价格是不是最终成交信息？
  Answer URL: https://hxgsc.com/answers/how-to-get-final-stock-and-quote
  Short answer: 不是。公开库存、价格和资料入口用于采购初筛，最终数量、批号、包装、交期、检测资料、含税报价、付款和交付条件都需要业务人员确认。
  Landing page: https://hxgsc.com/help
  Evidence: https://hxgsc.com/help, https://hxgsc.com/bom, https://hxgsc.com/products
- 下单前怎么确认批号、包装、检测资料和交期？
  Answer URL: https://hxgsc.com/answers/how-to-check-lot-package-before-order
  Short answer: 先在商品详情核对完整 MPN、品牌/制造商、封装、公开库存和资料入口；提交询价或 BOM 时写清目标数量、可接受批号、原包装/散装要求、是否需要检测资料、开票方式和交期。公开页展示的是采购初筛信息，批号、包装、检测资料、含税价和最终交付时间必须由业务确认后再下单。

  Evidence: https://hxgsc.com/products, https://hxgsc.com/bom, https://hxgsc.com/help, https://hxgsc.com/answers/how-to-get-final-stock-and-quote
- 确认交付、检测资料和最终报价前要补哪些信息？
  Answer URL: https://hxgsc.com/answers/how-to-confirm-delivery-inspection-before-order
  Short answer: 先进入服务承诺页核对完整 MPN、需求数量、品牌/制造商偏好、批号包装、期望交期、检测资料、是否含税、付款交付条件和可接受替代范围；再把这些字段带入商品询价或 BOM。服务承诺页只说明公开采购核对流程，不能当作某个型号的锁库存、最终报价、授权证明或替代批准。

- 多个型号或 BOM 清单怎么询价？
  Answer URL: https://hxgsc.com/answers/how-to-submit-bom
  Short answer: 进入 BOM 配单页，上传 CSV 或粘贴型号清单，并补充数量、品牌/备注、封装和交期。系统会把清单转交业务复核报价。

  Evidence: https://hxgsc.com/bom, https://hxgsc.com/bom-template.csv, https://hxgsc.com/help?topic=bom
- 商品详情页的信息怎么转成 BOM 核价？
  Answer URL: https://hxgsc.com/answers/how-to-turn-product-detail-into-bom-rfq
  Short answer: 先在商品详情页核对完整 MPN、品牌/制造商、封装、公开库存、参考价、起订量和制造商 PDF，再点击加入 BOM 或复制单型号询价备注。提交时补充需求数量、可接受替代范围、批号包装、交期、检测资料、含税报价和付款交付要求；详情页证据只用于采购初筛，最终库存、价格和可替代性仍以业务确认。

- 订购后缀和包装代码会影响采购吗？
  Answer URL: https://hxgsc.com/answers/how-to-read-ordering-code-before-rfq
  Short answer: 会。完整 MPN 末尾的后缀或包装代码可能代表封装、温度等级、包装方式、环保/车规等级、订购批量或客户特定料号。询价前应保留完整 MPN，打开订购后缀核对页或数据手册页，把后缀、品牌/制造商、封装、数量、批号包装、交期、检测资料和可接受替代范围写进 BOM；页面识别只用于采购初筛，不等于最终制造商含义、可售库存、最终报价或可替代证明。

- 批量采购前怎么选择数量阶梯和 MOQ？
  Answer URL: https://hxgsc.com/answers/how-to-choose-quantity-breaks-before-rfq
  Short answer: 先保留完整 MPN，打开数量阶梯核价页或商品详情，按 MOQ、试产数量、小批数量、量产数量和备货数量列出多个档位；再把品牌/制造商、封装、包装单位、批号要求、交期、是否含税、检测资料和可接受替代范围一起写进 BOM。公开 MOQ、库存和参考价只用于采购初筛，不等于锁库存、阶梯价承诺或最终成交价。

- BOM 只有型号或缺少数量品牌时可以先提交吗？
  Answer URL: https://hxgsc.com/answers/how-to-submit-incomplete-bom
  Short answer: 可以先提交，但建议至少保留完整 MPN，并尽量补数量、目标品牌/制造商、封装、交期、是否含税和可接受替代范围。缺数量或缺品牌的清单会先进入人工复核，业务会按公开现货、渠道库存、资料库候选和替代范围回访确认；不要把不完整 BOM 当作锁库存或最终报价。

- 原始 BOM 清单怎么整理成可询价格式？
  Answer URL: https://hxgsc.com/answers/how-to-clean-bom-before-rfq
  Short answer: 先保留每行完整 MPN，把数量、品牌/制造商、封装或关键参数、备注和可接受替代范围分列；再检查缺数量、重复型号、异常行和不明确参数。可以直接粘贴到华芯购 BOM 页，使用识别预览、整理格式、去重和异常行复制功能做采购初筛；最终库存、批号、包装、交期和报价仍需业务确认。

- 查到型号后怎么从购物车或 BOM 进入订单确认？
  Answer URL: https://hxgsc.com/answers/how-to-turn-search-cart-into-order
  Short answer: 单个现货型号先核对 MPN、品牌、封装、公开库存、包装和交期，再加入购物车进入订单确认；多型号或有替代要求时优先转 BOM，把数量、不可放宽参数、可接受品牌、批号包装和含税需求写清楚。公开页面只用于采购初筛，最终订单、库存和报价仍需业务确认。

- 搜索没有公开现货时还能继续采购吗？
  Answer URL: https://hxgsc.com/answers/what-to-do-when-search-has-no-stock
  Short answer: 可以继续。无公开现货不等于无法采购，建议保留原始型号或搜索词，先放宽品牌、封装和参数条件复查；仍无命中时转入 BOM 或寻料需求，并补数量、目标品牌、封装、交期和可接受替代范围，由业务继续核对渠道库存、资料库候选和替代料。

- 缺货型号或备货找料需求怎么提交？
  Answer URL: https://hxgsc.com/answers/how-to-request-backorder-rfq
  Short answer: 先保留原始型号或参数，把目标数量、期望交期、目标品牌/制造商、封装/关键参数、可接受替代范围、不可放宽参数、批号包装和检测资料要求写清楚；再从无结果搜索页或 BOM 页提交备货找料需求。缺货备货只代表进入人工寻源和渠道核对，不等于已经锁库存、锁价格或确认可替代。

- 搜索没有结果后应该怎么复查型号和替代料？
  Answer URL: https://hxgsc.com/answers/how-to-recheck-no-stock-search
  Short answer: 先保留原搜索词，再按完整 MPN、系列前缀、封装/参数、品牌/制造商四个方向拆词复查；同时打开资料中心确认 PDF、订购后缀和封装，再进入替代料页看同封装、同类目或同品牌候选。仍无公开现货时，把原始型号、复查过的关键词、目标数量、交期和可接受替代范围提交 BOM，由业务继续核对渠道库存和可供方案。

- 找不到原型号时能不能按封装找替代？
  Answer URL: https://hxgsc.com/answers/how-to-find-package-alternatives
  Short answer: 可以先按封装进入专题页或筛选页，例如 插件、SOIC-8、SOT-23、0603、SOP-8、SMD3225-4P，再结合品牌、分类、参数、库存状态和 PDF 资料确认候选，并在 BOM 中注明替代范围。

- 同封装型号能直接替代吗？
  Answer URL: https://hxgsc.com/answers/how-to-check-same-package-compatibility
  Short answer: 不能直接判断。插件、SOIC-8、SOT-23、0603、SOP-8、SMD3225-4P 这类封装入口只适合初筛，正式替代还要逐项核对完整 MPN、引脚定义、外形尺寸、关键电气参数、温度等级、生命周期、制造商 PDF 和应用场景，并把原型号、候选型号、数量、交期和不可放宽参数一起提交 BOM 复核。

- 某个具体型号缺货时怎么找替代料？
  Answer URL: https://hxgsc.com/answers/how-to-find-part-alternatives
  Short answer: 优先进入 /alternatives/{型号} 查看同封装、同类目、同品牌或制造商方向的候选，再把原型号和候选一起转入 BOM，补充数量、可接受品牌、不可放宽参数和交期，由业务与工程侧继续复核。

- 国产替代型号怎么确认能不能用？
  Answer URL: https://hxgsc.com/answers/how-to-verify-domestic-alternative
  Short answer: 国产替代先按原型号、封装、引脚、关键电气参数、温度等级、认证要求、生命周期和应用场景做初筛，再把原型号、候选国产型号、不可放宽参数、测试报告或认证资料一起转入 BOM 复核。不能只因为同封装、同系列或参数相近就判断等效，正式替代需要工程测试和业务确认供货、批号、包装、交期与报价。

- 商品详情里的 PDF 预览打不开怎么办？
  Answer URL: https://hxgsc.com/answers/what-to-do-when-datasheet-pdf-fails
  Short answer: 如果商品详情内嵌 PDF 因制造商站点限制、超时或跨站策略读取失败，应优先点击“打开制造商官方 PDF”或进入资料中心按完整 MPN 查询；PDF 预览失败不代表该型号不可询价。

- 查到 PDF 数据手册后怎么转 BOM 询价？
  Answer URL: https://hxgsc.com/answers/how-to-rfq-from-datasheet
  Short answer: 先从资料页确认完整 MPN、官方制造商、封装/引脚、关键参数、订购后缀和 PDF 版本；再进入 BOM 填数量、可接受品牌/制造商、批号包装、交期、检测资料、含税报价和替代边界。PDF 资料只用于工程与采购初筛，不等于现货、锁库存、最终报价或可替代证明。

- 库存品牌和官方制造商不一致时怎么判断？
  Answer URL: https://hxgsc.com/answers/how-to-handle-brand-manufacturer-mismatch
  Short answer: 电子元器件页面可能同时出现库存品牌、供应链品牌、资料库识别制造商和官方制造商。采购时应以完整 MPN、制造商官方资料、封装和商品详情中的制造商参考为主，再由业务确认真实供货品牌与批号包装。
