------Question for MAX903CSA Please Put your question below------

Hi,
Accoridng to your website, the MAX903CSA is obsolete, but you offer a part MAX903CSA+ as a direct replacement. When I go via the data-sheet link for MAX903CSA+what actually opens is the old MAX903CSA data-sheet. Does this mean these two parts are identical?

Thanks

For Maxim (Analog Devices) a + means it is RoHS Compliant (Lead Free)

If that is the only difference between the part numbers then the only difference will be the metal plating on the leads.

Hi Kristof_2649,

Thanks for reply. Your web-page covering the MAX903CSA list it’s production status as “Obsolete” but does not say this for the MAX903CSA+ implying that it is in current production. However if I ask google AI, it says that the MAX903CSA+ is obsolete. Please will youi confirm definatively if the MAX903CSA+ is or is not obsolete.

While you are doing this please will you also check the staus of the MAX9203ESA+T as there is a similar issue around this.

Best Regards

Robert Phillips
