Im trying to understand how to choose the right capacitor in order to do a full recap on a motherboard i have. The motherboard has many unkown brand bulged leaked fake caps from that era..
So instead of trying to find out if there are datasheets of such original crap i just I went to digikey.com and did a search for any good brand Replacement using the UF and voltage and then applied some filters.
1) a search was done for "1000uf 6.3v" then selected "Aluminum Electrolytic Capacitors"
2) to narrow things down, i selected
a) a known brand like Panasonic.
b) checkbox in stock
c) Operating temperature -40°C - 105°C
d) mouting hole: through Hole
e) Lead spacing: 0.138" (because the original has that spacing)
RESULT: that leaves me only part# EEU-FR0J102 , as a good candidate
Then followed with another search :
3) search done for "4700uf 6.3v"
a) same filters as before
b) lead spacing 0.197"
RESULT: gave me only 1 result part# EEU-FM0J472L
Probably someone at vogons has more experience and can guide me if what i did is ok
In my city i can buy some caps but the small shops all sell crappy unknown branded ones. And also when i buy them the only thing they understand is "Uf" and "voltage", nothing else (they don´t even sell SMD ones).
And that is all they got in stock.
1) I want to know if what i did is correct and if i should be adding any other filter.
2) I want to know what other brands should be good to choose besides panasonic.
3) And i want to know if a motherboard capacitor can be replaced with: the same UF and Voltage replacement capacitor but the replacement capacitor is labeled with "LOW ESR".
