1-3/4" is the longest standard coil roofing nail. Verify your roofing nailer accepts 1-3/4" — every Bostitch RN46, MAX CN445R3, and Metabo HPT NV45AB2 does, but a few short-magazine guns top out at 1-1/2".

When 1-3/4 inch is the right roofing nail length
Tear-overs need length
The most common reason to spec 1-3/4" is a tear-over: installing a new shingle layer directly over the old one. Code in most jurisdictions requires a minimum 3/4" deck penetration, and once you account for the existing shingle layer (~3/16") plus the new shingle (~1/4"), 1-1/4" doesn't get you there.
1-3/4" gives you the penetration you need without going to a framing nail. Verify your local code allows tear-overs before assuming this is your situation.
Florida HVHZ and designer shingles
Florida's high-velocity hurricane zone (HVHZ) code calls for 1-3/4" ring-shank coil nails on most asphalt shingle systems. Most heavyweight designer shingles (CertainTeed Grand Manor, GAF Camelot, Atlas Pinnacle) call for the same length and shank in their warranty docs.
For HVHZ work always pair with ring shank — Florida code requires it.
Verify your nailer accepts 1-3/4 inch
All major coil roofing nailers in current production accept 1-3/4" — Bostitch RN46, MAX CN445R3, Metabo HPT NV45AB2, DeWalt DCN45RN, and Senco RoofPro. A few older or short-magazine guns top out at 1-1/2"; check the spec sheet before loading.
