Jiggle / rattle on new thermostat housing

[Birth25130]

I received a new RCZ thermostat today. When I took it out of the box I noticed there’s a rattle sound when I tilt the thermostat housing from side to side.
Is it normal for that to happen?
Thanks!

I’ve fitted many Of these thermostat housings on various prince engines and never noticed any rattling, would assume its coming from the thermostat itself, I wouldn’t fit it, can you exchange for another one, I wouldn’t fit it, personally I would only fit a branded one and not a cheap one

It’s supposed to be genuine (but bought it from an eBay seller not Peugeot though).

Genuine Peugeot Citroen Engine Thermostat Housing with Wiring Cable 9808647080 | eBay Australia

The seller has confirmed that it’s supposed to be that way and sent me a video of another one in their store making the same sound.

Doesn’t make it right though - just some additional information.
