Varistor Identification Help

[Showa25]

Hi All,

Looking to confirm the specs/code on a leaded disc varistor. I’ve been able to figure the following:

S = leaded
10 = size (10mm)
K = Tolerance +/- 10%
275 = Max VAC (275v)

Not sure what the last line of digits represent, best I can tell it’s a date code?

This what I need to replace:

Here is the replacement I ordered:

Are they the same rating? Can’t find any reference to the last line anywhere or on the TDK spec sheets. (Again, assuming it’s a date/batch code..?)

Appreciate any help!!

Thanks,

They might be the similar.

Think I was able to finally find the appropriate tech sheet from TDK confirming the last line is the date code (YY/WW)

I saw 230V on the board, S10K275 may be undersized in this case, but correct for 115V line...

Yeah, it’s a 120v line and the 275 is what was originally on the board.

I was also able to confirm the rating with the distributor as well.
