MSP430G2955: MSL Humidity sensitive level

Susan Yang

Part Number: MSP430G2955

Dear team,

My customer bought two trays of MSP430G2955IRHA40R from Avnet. But they have different MSL level.

One of the two trays is made in China, the LOT number is 9023612CD9, the MSL rating is 2, the other is Malaysia, the LOT number is 8945174ML8, and the MSL rating is 3.

Is the MSL level different from the origin? Or is it related to production time? At what point did the material undergo a MSL level change?

Please help.

Hi Susan,

thank you for your question.

The different MSL level are correct. While the MSL for material from Malaysia is 3, the MSL for material from China is MSL 2.

The device was originally build in Malaysia only and later on also in China. During re-qualification for the A/T site in China, the device was passing MSL 2.

Hope this explains it.

Best regards Uwe
