I'll leave the actual question to other posters.

I'll add one of my own instead, to the OP: Are the pads in a state so that you could replace it, and how will you avoid heating away the other components around that area?

They're £9 - bin it and buy another.
It will probably cost more than £9 to fix it/get the part then it's your time wasted trying to fix it.

My Zero W died, no idea why. it was stored on my desk because I had no use for it since I got my 4B. no leds or anything - tried different PSU's/SDCARDS and nope. it's in the bin because it would cost way more than £9 to fix it.

It's probably still usable as if a Zero without WiFi or Bluetooth so I wouldn't bin it, but buying another Zero W probably is easier than fixing it.

I'd be tempted to see if I could replace the lost component with a bit of wire but that would make it non-compliant so best not to.

The only "white part" on a zero I know of is the camera connector which is non essential (unless you use the camera)

It's a bandpass filter for the wireless antenna.

The wireless interface will probably work without it, but with degraded reception and may have out-of-band emissions when transmitting.

I'd recommend not using it as a Zero W and instead using it as a Zero.
