If you can find a sprinkler with the same k factor and spray characteristics then you can just replace it. There is also a provision in the code book that says if the exact sprinkler is not available you can replace it with a sprinkler that is similar in k factor and spray pattern. NFPA 25
5.4.1.3* Special and quick-response sprinklers as defined by NFPA 13, Standard for the Installation of Sprinkler Systems, shall be replaced with sprinklers of the same orifice, size, temperature range and thermal response characteristics, and K-factor. A.5.4.1.3 It is imperative that any replacement sprinkler have the same characteristics as the sprinkler being replaced. If the same temperature range, response characteristics, spacing requirements, flow rates, and K-factors cannot be obtained, a sprinkler with similar characteristics should be used, and the system should be evaluated to verify the sprinkler is appropriate for the intended use. With regard to response characteristics, matching identical Response Time Index (RTI) and conductivity factors is not necessary unless special design considerations are given for those specific values.
