  • \$\begingroup\$ thank you for helping my question. other than SSI3439L (equation), because I find it hard to get it. \$\endgroup\$ – Adhe Pion Mar 15 at 22:39
  • \$\begingroup\$ @AdhePion - Welcome :-) Please read the tour and help center to learn more about the site and its rules. (a) You talk about "equation" in your comment. I fixed it in your question, and I think you mean "part number" here. You certainly don't mean "equation" - that's a mis-translation. (b) Your comment seems to be asking for alternative parts because you "find it hard to get" the original device. It is difficult to help with that type of (new) question, because we don't know which devices are easier for you to get! Note that, as explained in the tour, shopping questions are off-topic. \$\endgroup\$ – SamGibson Mar 15 at 23:54
