Sorry, you're right - tant caps are irreplacable in some applications. I overcorrected on madaxe_again's assertation that tantalum used universally in electronics, when really the number of places that it's used, and couldn't be replaced if supply was cut off, isn't huge. That number certainly isn't zero though.
