Replacement for Jamicon LP 200V 680uF capacitor

[rn170]

Hi All,

I have a broken subwoofer and it has a bulging capacitor which I think is the cause of the problem.
It's a Jamicon [LP] 85C 200V 680uF 905K0(M) snap-in

How critical is it that I replace with an LP one? I can't find LP ones on their own datasheet now.

Mine is 30mm D by 37mm H. Is it critical that I find one the same dimension?

I found these : https://uk.farnell.com/w/c/passive-...00v&range=inc-in-stock|exc-delivery-surcharge
but would any of them be unsuitable?

Thanks in advance

LP means low profile? Sorry I don't have the datasheet.

Electro caps, specially the larger ones, are usually the tallest components on any board. As such, for space constrained applications, manufacturers will offer shorter versions.

In my limited experience, because these shorter caps have a smaller surface area to dissipate heat, they usually carry a lower ripple current rating than its standard sized counterparts.

In any case, as long as the space allows, you can usually replace identically rated caps (85C 200V 680uF ) with bulkier devices.

But to be 100% sure, you would have to compare the ripple current ratings of both.

Thanks. I think this might be the datasheet https://www.distrelec.de/Web/Downloads/_t/ds/lp-series_eng_tds.pdf?pid=16754667
Seems to have a ripple current of 2.14. I'm struggling to find one so high. Shipping is expensive to the UK from that site.

is it in the power supply of the sub amp?.. if so it might have a height restriction to fit on the circuit board without coming in contact with the speaker frame or magnet.
