Close, but not necessarily identical. Besides the key items like wheel size and steerer diameter and lenght, there are other variations.
1- wheel/crown clearance. Often measured as axle to crown dimension, or sometimes as brake reach for a given wheel.
2- rake, or the distance forward of the steering axis of the front axle. On 700c forks this is usually 40-50mm.
3- braze-ons and other fittings including for canti or V-brakes, or fender eyes, rack mounts, etc.
Then there are the other items like whether the steerer is threaded or not, and for 1" forks the crown seat diameter which may be ISO, 26.4, or JIS, 27.0 or not machined and needing prep.
