I don't know, how about a jaycar rr2502? :-p
OK, newark = farnell, but I'm still not a fan of this method of description. Wouldn't "how does hole spacing at 15.06mm sound?" be better?
From the data sheet I'm guessing that we would have the pads 15.06mm apart?
Second question, why are we at 2.5W with a maximum load ever on a bad day when a second CPU snuck in and sat on top of the other one with a bunch of accessories of 1 Watt and a normal usage of around 0.1125 Watts and probably maximum of 0.25 Watts. A 1 Watt part makes more sense to me and a 1/4W would do, but you would never use that for this application...
Even though newark is farnell, the part numbers are different. Your newark number corresponds to this farnell (most countries) number 1155286
