DIP socket, 6 pins, 0.3" row spacing
The 1-2199298-1: That 0.3" row spacing is the standard for narrow DIP ICs — think 6-pin op-amps, voltage regulators, or optocouplers in a DIP-6 package. The open-frame PBT housing lets air flow under the IC, which helps with convection cooling in through-hole assemblies.
