Available part compatible with MP86941

[Green Probe]

Hi all! I'm looking for a MP86941 "Intelli-Phase Solution", and there is only one guy on ebay that has them in the U.S. Is there a cross-compatibility search-engine for these, or does anyone know of a more available compatible part?

For reference, this is a part for an Alienware LA-761P Rev1.0 motherboard, supplying the CPU.

Thanks for any input you have!
