Default Source for quality stumpy 450v/150uF STGCON cap replacement

I am attempted to replace this capacitor to repair a power supply. I put in a random used NCC KXG 450v/100uF and it worked but it's too tall and skinny to reinstall the heatsink and even if I drill a big hole in the heatsink for the cap it would still be too tall and the power supply will no longer fit in the network switch.

The original cap seems to be 35mm in diameter and maybe 25mm in height. I could probably go up to 30mm in height and be OK.

Thanks for any help with a source for these, I only need one or two, and the cheaper the better. I found some on eBay that may work but they're either lousy/no-name brands or they might be fake.

Do you have any room to laying the down on it side or is space a big problem
If so could move the capacitor over to an area to miss the heat sink

Digikey has a number of them, enter the capacity and voltage, then sort by height small ~ large

Is this one OK? Dimensions are fine for what I need.

Basically anything will be fine, choose the higher temp rating and then higher ripple rating (in that order)
And of course something that fits, both diameter wise but also terminal wise (snap in with the correct spacing between the legs)
I was going to suggest you this in your other post when you had not specified the dimensions.
So I just searched for the smallest in stock and this Würth cap turned up:
