I need a new EVAP Purge Control Valve

Does anyone know the differences between these two Nissan part numbers?
149303M201
1495635U10

They're bost listed as purge control valves, but one is way more expensive than the other.
Thanks for any help

It's been a year since the question was asked, but for what it's worth, the first is the EVAP canister purge control solenoid valve, it has two hoses coming off of it and an electrical connection - under the hood, find the VIN on the firewall, third number from the end on the VIN. From there go toward the radiator about three inches.

The second is the EVAP canister purge control valve - it has three hoses connected to it and is (if memory serves correct) about two or three inches in front (toward the radiator) of the solenoid above and a little toward the battery.
