It can be any of these:
* JST - VH
* Molex - 35313 + 35156
* Molex - L1NK 396
* TE - Economy Power 3.96
* TE - Economy Power II
VH: it
is this, or a clone thereof.
Molex 35313 + 35156: Nope, doesn’t match. Different latch and keying.
Molex L1NK 396: Nope, doesn’t match,
completely different latch design.
TE Economy Power and Economy Power II: while very likely mating-compatible, not a match. The latch has little barriers next to it that the JST VH doesn’t have.
As for the database,
here’s the link made clickable. (The forum software screws up with many special characters, like the pipe, if you don’t manually create the link and link text.)
That’s a neat site! I actually had recently had the thought (as a connector nerd) that making such a site might be useful. Cool to see you’ve undertaken that! I will give a bit of constructive feedback, though: the usability is terrible and it seems rather buggy. (For instance, there’s no obvious way to go back to the list of candidates, once you’ve selected one. The little back arrow next to the number in a circle goes back, but the component list then doesn’t contain all the same items. Browser back doesn’t work, either.)
