AI replacement insight

Electrical riskmedium

Mismatches in trip current or time-to-trip can affect protection.

Package risklow

The 0805 package is a widely available standard.

Sourcing risklow

PTC fuses are a common component with many vendors.

Can it be replaced directly?

SMD0805-005C-60V is a potential direct replacement, matching the 0805 package and key 50mA hold / 150mA trip currents. Its higher 60V rating is an upgrade. Engineering validation is still required.

Best replacement path

The best path is to use SMD0805-005C-60V, which matches critical currents and offers a superior voltage rating.

Main risk

The main risk is using a part with a higher hold current, which would fail to protect the circuit at the intended threshold.
