Try using TLP627 from Toshiba, they are usually used by these designers but they are more expensive so some use the cheaper and inadequate PC817 and hope that it will work. However if the designer has switched the base and emitter that is a design error. You can look at this document that has been around for ages on driving Nixies: http://web.jfet.org/nixie-1/NixieTransistors.pdf
