Dear, We've got a question about the marking of IGBT STGWA40H120DF2.

[TOuya.1177]

Dear,

    We've got a question about the marking of IGBT STGWA40H120DF2. The datasheet shows the marking of STGWA40H120DF2 is G40H120DF2; However, we bought two datecode of the part: 

Part A: 19+  Marking: GWA40H120DF2

Part B: 20+  Marking: G40H120DF2

Could you please help check is there any difference between two datecode parts? Are they the same part?

Please see the details of two parts. Thanks!

Best Regards,

Tony
