2.0 x 1.7 x 0.85 mm. Datasheets disagree: both part names say BRG (FI) or RGB (FJ) but both sheets say the wire order is GRB; the FJ sheet’s wavelength table gives G 460-475 nm and B 520-535 nm (rows swapped); the FJ spec is 12 mA with a +/-0.15 us timing tolerance while the FI is 5 mA with +/-0.05 us. The ‘light type’ line reads ‘scintillation - quick scintillation’ on both. Package printed as ‘2.01.70.85 mm’; LCSC lists FJ as ‘2x1.7mm’. LCSC stock: FI 2,990, FJ 2,980.
