Is calculation of SINAD from ENOB given in datasheet accurate for RT comparison?

When looking for a replacement in case of an ADC the AD product list doesn't have the SNR or SINAD values for most of the listed products especially 24 bit sigma delta. So will it be accurate to compute the SINAD value from the Effective Number Of Bits given in the datasheet and compare it with the original one to be replaced  to  make a fair decision? (ad7796 is an example)
