FAQ

Is GD32F103ZET6 currently available?

Availability is shown on this product page from live inventory and changes as lots move. Submit an RFQ with quantity and required date so SJ Chip can confirm remaining stock, date code, and lead time before you issue a PO.

Can GD32F103ZET6 be replaced by STM32F103ZET6?

STM32F103ZET6 may be a potential alternative / requires engineering validation (pinout, firmware, clocks, power, and errata). It is not a direct replacement. Do not change the AVL until the customer's engineering team approves the evaluation.

Is this a drop-in replacement?

No. SJ Chip does not list parts as drop-in or direct replacements. Any nearby MPN is a potential alternative / requires engineering validation before production use.

How can I request a quotation?

Open https://www.sj-chip.com/rfq, enter the full part number, quantity, and required date. The sourcing team replies within 24 working hours with availability, condition, and lead time on the quotation.

Can GD32F103ZET6 replace STM32F103ZET6?

Pinout is similar on many boards, but clocks, USB, and wait-states are not guaranteed identical. Plan a bring-up, not an AVL-only swap.
