Purchasing DS1921G

------Question for DS1921G-F5

Hi we would like to place order for DS1921G, however it shows DS1921G-F5 on your website, I would like to know what’s the difference between these two, can it be replace by DS1921G-F5?

Further more, to activate DS1921G, do we also need to purchase some sort of device before using it? If so, can you advise as well? Thanks.

Hi,

Thank you for choosing Digikey! The F5 suffix indicates the 16.3mm Diameter stainless steel can enclosure that the Ibutton is packaged in. In order to get started you will need an Ibutton starter kit.

I would recommend DS1921K#-ND or DS9092K#-ND
