Closest hold current match found (1.5A). A 2920 PTC fuse with same voltage but requires engineering review.
Best Alternatives to SMD2920P100TF
Finding a substitute for the RUILON SMD2920P100TF PTC fuse requires careful matching of its 1.1A hold current and 33V rating in a 2920 package. Alternatives exist but often have different current ratings that need review.
AI replacement insight
Electrical riskmedium
Higher hold current alters the protection characteristics of the circuit.
Package risklow
All candidates share the same 2920 package, ensuring form and fit compatibility.
Can it be replaced directly?
No direct, drop-in replacement was found. All candidates have a higher hold current than the original 1.1A, which changes the circuit's protection level.
Best replacement path
Select a candidate with the closest hold current, like SMD150L (1.5A), and verify if the increased current threshold is acceptable for the application.
Main risk
The primary risk is insufficient overcurrent protection due to candidates having a higher hold current (1.5A to 2.0A) than the target's 1.1A.
