Watch out for the contact material and switching speed.
The original is 12msec max operate and 8msec max
release. The first (and cheapest) one in the list is
8msec and 6msec respectively, which should be faster
than the original. However, the contacts are AgSnO2
which is better than AgCdO contacts of the original.

Well, that one is silver/nickel per the data sheet. The
AgSnO2 version would be RT423012, which DigiKey doesn't
stock.

But this one:

74

is silver/nickel with gold plating - per the datasheet.
Would that be worth a couple extra bucks?
