Connector rated voltage vs IPC-2221B and IEC 62368 and UL796
[Rosenberger 23C25D-40ML5](https://products.rosenberger.com/radio-frequency/connectors/274270/23c25d-40ml5-multiport-8-channels-angle#)
specifies 500V RMS rating:

Looking at the [recommended landing pattern](https://products.rosenberger.com/_ocassets/mb/MB_501B.pdf)
you can see that the distance between the signal landing pad and housing of the connector is 0.3025‬mm. IPC-2221B specifies minimum conductor spacing of 0.8mm for external component termination, uncoated for 151-170V, which is already considerably larger spacing than the footprint.

IEC 62368 specified minimum creepage distance for basic insulation, pollution degree 1 (Most favorable) and 500V RMS as 1.3mm, which is also considerably larger.

I have 2 questions:

1.) If I use this connector at its rated working voltage, does that automatically mean I am not complying to IEC 62368 safety standard?

2.) Would the only circumstance under which this connector could be used at its rated voltage be when the design does not have to comply with safety regulations?
