Русско-англо-русский юридический словарь

A suspended sentence is a sentence on conviction for a criminal offence, the serving of which the court orders to be deferred in order to allow the defendant to perform a period of probation. If the defendant does not break the law during that period and fulfills the particular conditions of the probation, the sentence is usually considered fulfilled. (Wikipedia)

While both related to the judicial process, a suspended sentence and probation aren’t synonymous. The former refers to a judicial penalty where jail time is put on hold, while the latter offers an alternative to jail, letting the defendant serve their time within the community, monitored by a judge or probation officer.
