5300ce 68uf cap

Hey, just checking, any reason why the 5300ce LCD cap is so huge? Wondering if it’s safe to replace with a tiny tantalum.

Here a pic for reference (tant on the left, original on the right).

That’s just how small they could make an electrolytic at that time. You’re fine to swap it for a tantalum.

Thanks. I went ahead and it didn't cause any issues. It's a super nice display. Now I need to decide whether I want a 190ce and a 5300cs with a ce board, or 190cs and 5300ce. Decisions, decisions...

What's the voltage rating on that tantalum? I interpret "686A" as a 6V-rated 68uF cap, but I hope I'm wrong. The original cap appears to be 68uF 10V.

It's 68uF @ 10v.

First two digits are the capacitance, third digit is multiplier, and A is code for 10v.
