Older polystyrene capacitor replacements

------Question for 860020672005

These are 0.047uf J(1%) polystyrene capacitors that are used in an amplifier from 2001. The pictures of the exact part are below. My question is what can be used in its place now that they are no longer available?

Typically ceramic or polystyrene capacitors are used to replace this, as I recall.

Seems to me our most likely options would be part number 399-C331C473F5G5TA-ND (ceramic) or 2870-MKP1837347161G-ND (polypropylene). The polypropylene option I linked might be too large, so double check the measurements if you decide to get that one.
