Hi, I'm Mike and I'll be assisting you. Please stand by while I review your question.
The use able service life of detectors is 8 yrs. If that old, I suggest replacing all of them. It having a yellow interconnect wire is not what can be identified. If you look at the other detectors, you should see a make and model number. You can find an exact replacement with that information.
To be comparable they all need to be the same. To verify they interconnect touch the white and yellow wires together. As I told you, detectors are recommended to be replace every 8 yrs. If my answer didn't help, I'll opt out.
