A 1206 slow-blow fuse from the same manufacturer with a lower 2.0A current rating; may cause nuisance trips.
Finding a substitute for the Littelfuse 046802.5NRHF, a 2.5A 63V 1206 slow-blow fuse, requires careful matching of current rating and time-current characteristics. Alternatives exist but may have different current ratings, requiring review.
Current rating mismatch is a critical electrical parameter for fuses.
1206 is a standard package, so form-fit is generally not an issue.
No direct, drop-in replacement was found in this batch. All viable candidates have different current ratings, which requires engineering validation.
Search for 1206 slow-blow fuses with exactly 2.5A current and >=63V voltage ratings from reputable manufacturers.
The primary risk is mismatching the current rating, which can lead to either circuit damage (if too high) or nuisance failures (if too low).
