STM32F103C8T6 with MSL 2 and 3? Please advise.

[ENeoh.1]

We bought STM32F103C8T6, COO is Malaysia, but MSL on the label is MSL 2, is it correct ? Because we found official datasheet for this P/N is MSL 3. Could you please help explain why one p/n with two MSL ? Thank you.

Hello @ENeoh.1​ 

I seems the MSL level depends on the package used, for example MSL level as per JEDEC J-STD-020 is considered to be 1 for all MCD WLCSPs.

For the package UFQFPN32 is qualified for MSL3.

I will check with the team about MSL 2 for STM32F103C8T6 and I will be back to you soon with update.
