SVF Boards, 220P Xicon Film Styro Caps - alternative?

These:

are currently on back-order so was wondering if anyone has a suggestion for an alternative, basically what are the key characteristic required in the circuit there?

Could you substitute a different capacitance? 180p or 270p? Different type of capacitor?

220pF NP0/C0G ceramic with a tolerance < 2.5%

Thanks Olivier.

Unfortunately all my searching turns up non-stocked items at Mouser. Plenty available with 5% tolerance though.

What about these?

The original BOM part was 5% tolerance so would that be OK?

Looks good.

Thanks Olivier.

FYI, smallbear has all sorts of polystyrene caps in stock.
