Tsar Bomba was a modification of an earlier project, RN202, which used a ballistic case of the same size but a very different internal mechanism. Many published books, even some authored by those involved in product development of 602, contain inaccuracies that are replicated elsewhere, including wrongly identifying Tsar Bomba as RDS-202 or RN202.
