I'm probably wrong but as I don't know too many compressed thin sans like this one (and also because of this /S), I'd probably start with Chalet Comprimé Milan 60/80 mainly lowering crossbars of /A, /H and /E.
Some more: Cyclone Inline, Maxwell Sans UltraLight, Catorze27 Light, Title Gothic Light, Rama Gothic Expanded Thin, Cactus Light, Heroic Condensed Light
