How many times have you found a supplier who makes "almost" what you need? By the time you go through the hoops to make it "exactly" what you need, sometimes it's easier to build it.
Every time!
By the way, there are four ways to get 625 ohms using standard EIA-96 (1% or better) values in series:
475+150, 523+102, 324+301, and 316+309.
Also, 16.9K in parallel with 649 gets you pretty close.
(I got tired of doing this stuff by hand a long time ago, and wrote some utility programs to find the best series, parallel, and ratio values.)
