Questions about LT8304-1 reference circuit in Design Note


My customer are designing a 500Vdc output curcuit with LT8304-1.

And for this , they refered below curcuit of Figure 4 "A complete 800 V/10 mA isolated flyback converter from a 4 V to 18 V input"  in Design Note "1000 V Output, No-Opto, Isolated Flyback Converter".

Q1) In this referece design, would you provide a datasheet of "SUMIDA 10380-T030" at T1?

Q2) When they want to get a 500Vdc output,could they use same devices (with same values) in a circuit of Figure 4. except 374kohm (Rfb)?

Please advise me.
