Nine "entities" will also be targeted by the sanctions, which were agreed at an emergency meeting of foreign ministers from the 28-nation European Union in Brussels last week, several sources told AFP.
The new additions must be formally approved when the foreign ministers meet again on Monday.
None of the 19 new figures targeted for travel bans and asset freezes is "top level", the sources said, while only one of the entities is Russian.
The crisis in Ukraine began in November 2013 when the then-president Viktor Yanukovych, under pressure from Moscow, refused to sign a deal deepening ties with the European Union, sparking protests which led to his overthrow.
The EU first imposed travel bans and asset freezes on a number of individuals after the Crimea annexation but dramatically strengthened sanctions to include economic sectors after the shooting down of Malaysia Airlines flight MH17 in July.
Deep divisions in the EU between hawkish eastern European states and others that fear the impact on their trade ties with Russia have been exacerbated with the recent election of a Greek government that stressed its determination to keep up relations with Moscow.
