TECHFUSE
A pin-compatible upgrade with identical hold/trip current and a higher 24V voltage rating for improved robustness.
Reviewing alternatives for the Bourns MF-PSMF010X-2, a 100mA/15V PTC resettable fuse in an 0805 package. Key considerations for replacements are matching the hold current and package, while ensuring adequate voltage and fault current ratings.
Low if hold/trip currents are matched. Pay attention to voltage rating for design margin.
0805 is a standard SMT package with a consistent footprint.
Check stock and lead times for the chosen alternative from authorized distributors.
Direct replacement for MF-PSMF010X-2 should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
The TECHFUSE SMD0805-010-24V offers an upgrade path with a higher voltage rating, providing better design margin.
The main risk is selecting a part with an incorrect hold current, which would compromise the circuit's overcurrent protection.

| Feature / factor | MF-PSMF010X-2 | SMD0805-010-24V | SMD0805B010TF | Alt 3 | Compatibility / risk |
|---|---|---|---|---|---|
| Package | 0805 (2012 metric) | 0805 | - | 0805 (2012 metric) — Form factor matches. | |
| Current | 0.1A | 100A | - | 0.3A — Trip current matches. | |
| Voltage | 15V | 24V | - | 15V — Identical voltage rating offers no additional safety margin. |
Verified drop-in options for MF-PSMF010X-2 are limited in the current batch. Review candidates marked Strong match or Datasheet verified, and validate package, pinout, and electrical limits before committing a BOM change.
