Find and compare substitutes for the BNstar SMD0805-020C-33V, a 33V, 200mA PTC resettable fuse in an 0805 package, used for overcurrent protection in compact electronics.

AI replacement insight

Electrical riskmedium

Substitutes must match voltage, hold current, and trip current. A lower voltage or higher current rating is a high risk.

Package risklow

The 0805 package is standardized, making physical replacement straightforward.

Can it be replaced directly?

Direct replacement for SMD0805-020C-33V should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.

Best replacement path

The BHFUSE BSMD0805-020-33V is the most direct replacement, matching all key electrical parameters and package size.

Main risk

The primary risk is selecting a part with an incorrect function (e.g., a varistor instead of a fuse) or with lower voltage or current protection ratings.
