A functional alternative in the same 0805 package and 60V rating, but with a significantly higher 40mA hold current.
Finding a replacement for the BHFUSE BSMD0805-002-60V, a 60V 20mA PTC fuse in an 0805 package, requires careful matching of hold current, trip current, and voltage rating to ensure proper circuit protection.
Hold/trip current mismatch alters circuit protection.
Alternatives share the same 0805 package.
Finding an exact match for the low hold current may be difficult.
No direct pin-to-pin replacements have been identified. Alternatives exist but have different current ratings, requiring circuit protection analysis.
The best path is to find a PTC fuse with a 60V rating, 0805 package, and a hold current as close to 20mA as possible. Candidates with higher hold currents (40-50mA) are available but pose a risk of not protecting the circuit as intended.
The primary risk is using a replacement with a higher hold current, which may not trip under fault conditions expected by the original design, potentially leading to circuit damage.

| Feature / factor | BSMD0805-002-60V | SMD0805-004C-60V | SMD0805-005C-60V | Alt 3 | Compatibility / risk |
|---|---|---|---|---|---|
| Package | 0805 | 0805 | 0805 | 0805 — Form factor matches.; SMD0805-005C-60V: Form factor matches. | |
| Voltage | 60V | 60V | 60V | 60V — Maximum voltage rating matches.; SMD0805-005C-60V: Maximum voltage rating matches. | |
| Current | 20mA | 40mA | 50mA | 40mA / 50mA — Hold current is 2x higher, altering protection level.; SMD0805-005C-60V: Hold current is 2.5x higher, altering protection level. | |
| Resistance | 12 Ω | 5.0 Ω | 1.5 Ω | 5.0 Ω / 1.5 Ω — Lower initial resistance is generally favorable.; SMD0805-005C-60V: Lower initial resistance is generally favorable. |
Currently, no drop-in alternative is confirmed. Functional alternatives like BNSTAR's SMD0805-004C-60V exist but have a higher hold current (40mA vs 20mA), which requires careful engineering evaluation before use.
