For the QRV07 parts I've spent $127.43 from Digikey and Newark in the USA, including shipping.
It's taken an awful lot of time to find everything, trying to match parts with specs. I hope there's been no mistake in part selection. If I did this again I would order everything possible from Elfa, despite paying more for shipping and maybe customs duty, since most of the part numbers are already on the BOM.
There's one last little part I can't find that no distributor in the US has in stock (and some want to sell me over 1000 pieces to back-order it). It's the two Kemet/Evox Rifa foil capacitors (Elfa part 65-557-59) for C1 and C8. Would anybody have a couple of these lying around? I can pay via Paypal or wire transfer in EUR, or US$$.
Alternatively, how closely do the specs have to match that particular capacitor? Newark has a similar one in stock, Kemet part #LDEEC3100KA5N00, but it's rated at higher voltage and tolerance: 0.1 microfarad, 100V, +/-10%, 2220, polyethylene naphthalate. Another is rated 1.0uF, 10%, 50V. Would those ruin the QRV07 board or its performance? Mouser has a closer one in stock in a smaller size -- 0.1uF, 10%, 50V, 0.8 DF, but size 1210 (3225 metric), only half as big. Mouser has another at 0.1uF, 10%, 63V. 0.8DF, size 1812 (4532 metric).
I'm no electronics expert at all so all this is confusing.
