which polaroid 600 camera uses spectra platinum film?

i have a sun 600 polaroid but the spectra platinum is too big.

None of the 600 series cameras can use Spectra Platinum film (or any Spectra film) due to different film formats. The following cameras can load Spectra film:
Image, Image 2, Image Elite Pro, Spectra, Spectra 2, Spectra 1200 series (i, si, FF), Spectra Onyx, Spectra Pro, Pro Cam
For differences between those cameras please see my source:

This is certainly the completest listing of Polaroid cameras you find on the net.

So you can’t use the film in your camera you either have to get a suitable camera (they go cheap nowadays) or you sell the film over Ebay etc. and get 600 film e.g. from Amazon.
You might also find someone who is willing to swap films with you.
