In case anyone is interested i have sourced equivalent parts for most of the components from Newark. a couple i had to get from tayda because mouser didn't stock some of them.
These are not the newark part numbers, but the what Newark uses as the manufacturer part #. from what i can tell they should be the equivalent to what is used in the mouser BOM.
The Tayda #'s are the Tayda sku #'s.
Hope someone finds this useful and can save themselves the time i spent.
Cheers
