Hi, I need to replace CAP C7240 on a 820-3332 Macbook pro retina. the CAP is a 68uf 20% 16v poly-tant case-d2e-sm but cannot find them anywhere. I can only find the in a D2 size. Thanks!
Than you everyone for your help, I was able to replace it with mouser part number 80-T520D686M16ATE50 . Everything is back up and running.
https://beetstech.com/store carries a lot of the repair electronic components. Ask them.
If it fits and is rated at the minimum voltage and fardas then it may be compatible.
