Matthew Brabham will race for the Andretti Formula E team in Malaysia while Charles Pic is on Lotus Formula 1 team reserve duty at the Abu Dhabi Grand Prix.
Pic and fellow Frenchman Franck Montagny are Andretti's main FE drivers, but Pic is required over the clashing Yas Marina F1 weekend and in the subsequent test.
Brabham has already tested the Andretti FE car during pre-season running at Donington Park.
He has driven for Andretti's junior arm for the past two seasons, winning the 2013 Pro Mazda title and then finishing fourth in Indy Lights this year.
The United States-born 20-year-old is the grandson of three-time F1 world champion Sir Jack Brabham and son of former CART Indycar and sportscar racer Geoff.
This weekend's race in Putrajaya ends a two-month gap in the FE calendar since its inaugural race in Beijing.
