That must be a tricky search. Here is the RM12 engine from SAAB Gripen engine (per Wiki):
Length: 4.04 m (13 ft 3 in)
Diameter: 0.87 m (2 ft 10 in)
Dry weight: 1,054 kg (2,324 lb)
Maximum thrust: 18,100 lbf with afterburner
The Eurojet EJ200 (Used in Eurofighter Typhoon) seems like a good match, being lighter, narrower and more powerful.
Length: 4.0 m (13.1 ft)
Diameter: 0.74 m (2.4 ft)
Dry Weight: 989 kg (2,180 lb)
Thrust: 20,200 lbf with afterburner
There's also the Safran M88-2 (Used in Dassault Rafale), which is smaller, but less powerful. And France/Dassault may not want to power its competitor.
Length: 3.53 m (11.6 ft)
Diameter: 0.69 m (2.3 ft)
Dry Weight: 897 kg (1,977 lb)
Thrust: 16,800-17,500 lbf with afterburner
The EJ200 option was off the table in the last decade, but it's different times now.
