BHFUSE
Form-fit compatible PTC fuse with a lower hold current (300mA) and higher voltage rating (30V).
BSMD0805-035-24V is a 24V, 350mA PTC resettable fuse in an 0805 package. Finding a suitable replacement requires careful matching of hold current, voltage, and power ratings to ensure proper circuit protection.
Hold current mismatch is a critical design parameter for fuses.
All viable candidates match the 0805 package.
No direct, drop-in replacement was found. All viable alternatives have different hold currents and require engineering review.
Review ASMD0805-050-24V for circuits tolerant of higher current, or BSMD0805-030-30V if a lower trip point is acceptable.
The primary risk is a mismatch in hold current, which can lead to failed protection (too high) or nuisance tripping (too low).

| Feature / factor | BSMD0805-035-24V | ASMD0805-050-24V | BSMD0805-030-30V | Alt 3 | Compatibility / risk |
|---|---|---|---|---|---|
| Package | 0805 | 0805 | 0805 | 0805 — Package size matches.; BSMD0805-030-30V: Package size matches. | |
| Voltage | 24V | 24V | 30V | 24V / 30V — Maximum voltage rating matches.; BSMD0805-030-30V: Higher voltage rating provides more margin. | |
| Current | 350mA | 500mA | 300mA | 500mA / 300mA — Higher hold current may not protect the circuit as intended.; BSMD0805-030-30V: Lower hold current may cause nuisance tripping. | |
| Power | 0.6W | 0.5W | 0.5W | 0.5W — Lower power dissipation rating.; BSMD0805-030-30V: Lower power dissipation rating. |
No single 'best' alternative was found. ASMD0805-050-24V has a higher hold current (500mA), while BSMD0805-030-30V has a lower one (300mA). The choice depends on whether your circuit can tolerate a higher protection threshold or risks nuisance trips.
