按 BOM 提交需求
多型号需求请补齐数量、品牌偏好、封装、目标到货日和不可放宽条件，方便统一核对。
提交 BOM核对资料与替代边界
资料用于工程和采购初筛；替代候选要继续核对脚位、封装、参数和应用条件。

SOURCING FAQ
Electronic components sourcing FAQ
How can I source an electronic component by manufacturer part number?
Search the complete MPN first, then check the public brand, package, category and datasheet fields. Submit the MPN, required quantity, package and delivery target for a business confirmation of stock, price and lead time.
What should I include in an electronic components BOM request?
Include the complete MPN, manufacturer preference, quantity, package, target delivery date and any non-negotiable parameters. Add alternate-part requirements separately so sourcing and engineering checks are not mixed.
Are public stock, pricing and lead-time details final?
No. Public information supports initial sourcing only. Final quantity, price, lot code, packaging, lead time, inspection documents and tax terms require business confirmation.
Can I request alternative electronic components?
Yes. Provide the original MPN, package, application and parameters that cannot change. An alternative is a sourcing candidate only and must be verified for pinout, package, parameters and application conditions before use.
Where can I find public product and procurement information on HXGSC?
Use the product search for MPN screening, the datasheet center for public documents, the alternatives center for candidate screening, and the BOM page for multi-line sourcing requests.
