How can I identify varistor which have been blew up?

[chth96]

I mistakely pluged 100v japanese retro game console to 220v outlet.
So It seems that glass fuse and varistor have been blew up.
I can identify that voltage and ampere value of glass fuse(250V LF 1.6A),but It is impossible to identify varistor type in my sega saturn PSU(YAMAHA 35M07U XR258)
Is there any way to identify varistor type in my sega saturn PSU?
Any reply would be appreciated.


EDIT:
It seems that I finally found out what type this black varistor is. It is Panasonic ERZV05D221 “ZNR” Transient/Surge Absorbers (Type D) Varistor Voltage of 220V. 5mm diameter.
But It is very expensive varistor in my country.
Is there any alternative varistor which substitute for Panasonic ERZV05D221?

which country ? they are cheap here

In my country,any electronic component which came from japanese is very uncommon and rare,
So I regularly use aliexpress shop where has some electronic component I am looking for.
But it seems that I have to purchase ERZV05D221 more than 20 quantity in aliexpress shop and Its price is quite expensive.
there is no aliexpress shop where allow to purchase less than 10 quantity of ERZV05D221..

yes they are expensive in indonesia i just looked . dont know the exchange rate at the moment but looks 5 times what it is here . like 4 or 5 bottles of bintang ..expensive for 10 .

i checked exchange rate and was surprised 1 GBP = 19,566.8 IDR , it was only 1200 when i was there . so the price looks good to me from RS .

Its price is reasonable but Delivery (flat rate) price is ridiculously expensive.

Subtotal SGD4.65
Delivery (flat rate)* SGD 40
Total SGD44.65

I would prefer to purchase from aliexpress where the Delivery price is much cheaper than rs-online..

can a local shop get them for you ?

ERZV05D221 spec is 5mm 220V @ 0.1mA, max. 140VRMS or 180VDC. Substitute 05D221K or 07D221 a little bigger at 7mm from Ali.
It does not solve the problem of 100VAC PSU and you have 220V... The primary cap is only 200VDC in the pic.

Thank you very much for reply! I already have Down Trans Voltage Converter 220v to 100v,I mistakely pluged 100v japanese retro game console to 220v outlet.
Now,It is possible to purchase alternative varistor from aliexpress at a reasonable price.
By the way,I have another PSU for same game console, But this spare PSU can not be replace with problematic PSU, Because it has only 4 pin connector instead of 5 pin.
It seems that there is green varistor close to glass fuse and it is written "O5 220NA 53" on it.
I cannot even identify its brief spec, But Is it Okay to pull green varistor out from spare PSU and solder it to replace with blown up black varistor?
