Input bias current is 150 nA typical, and input offset voltage is 500 µV.
The 8-VSSOP package has a 0.65 mm pitch and exposed pad underneath — will it survive the hot air? Yes, with a preheat around 150°C and a focused nozzle. The centre pad is not a thermal slug, so it reflows cleanly.
The RC4558P is the same dual op-amp in a DIP-8 package. The RC4558DGKR is the surface-mount VSSOP-8 variant — electrically identical, but the footprint is different. If your board layout accepts the 0.65 mm pitch VSSOP, it is a direct functional substitute.
