Genuine Vaillant Pressure Sensor?

[Traveller]

Hi all.

I understand the official genuine Vaillant water pressure sensor has part no. 0020059717, however, reputable sites like Screwfix advertises it as 0020059717 but the image of the item shows 0020036671 (see link below).

Due to sites like Screwfix being reputable, is it correct to assume that the part with the alternative number is also a genuine Vaillant part?

Another number I have frequently seen on this part sold in various places is v19577448 (see link below).

Is the above number a genuine Vaillant part number also or is it just a 'compatible'?

Thanks for any clarification.
