Fuel Shut Off Solenoid Question

[Haoleguy]

My Landini Mistral 50 has a bad fuel shut off solenoid. The engine is a Yanmar 4TNV88 and the shut off model number is a Woodward #1503ES-12S5SUC5S. Figuring my JD dealer might have this part as many Deere tractors have Yanmar engines I gave them a call and after a bit of detective work it turns out they carry M806808( #1503ES-12S5SUC12S). Not sure what the Woodward coding means but both Woodward numbers are close and have a similar flange attachment. So my question is are these interchangeable? Anyone know how to decode the Woodward numbers? I tried giving them a call earlier but ended up in the phone roulette wheel which finally said leave a message.

Turns out that Deere M806808 fuel shut off solenoid is Woodward #1503ES-12S5SUC5S in the Deere OEM box. Replace failed unit with new and the Landini Mistral fired right up.
