RUILON
Strong alternative with matching package, voltage, and hold/trip current ratings.
Find and compare replacements for the Bourns MF-PSMF035X-2, a 6V, 0.35A PTC resettable fuse in an 0805 package. This guide helps identify alternatives based on key electrical and mechanical parameters.
Key ratings match, but secondary parameters like trip time and resistance profile need verification.
Standard 0805 package ensures physical compatibility.
Direct replacement for MF-PSMF035X-2 should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
SMD0805P035TF is the most promising alternative as it matches all key electrical and physical specifications of the MF-PSMF035X-2.
The primary risk when substituting PTC fuses is a mismatch in the time-to-trip characteristics, which could alter circuit protection behavior under fault conditions.

| Feature / factor | MF-PSMF035X-2 | SMD0805P035TF | SMD0805P050TF | Alt 3 | Compatibility / risk |
|---|---|---|---|---|---|
| Package | 0805 (2012 metric) | 0805 | 0805 | 0805 — Package size matches.; SMD0805P050TF: Package size matches. | |
| Voltage | 6.0V | 6.0V | 6.0V | 6.0V — Maximum voltage rating matches.; SMD0805P050TF: Maximum voltage rating matches. | |
| Current | 0.75A | 0.75A | 1.0A | 0.75A / 1.0A — Trip current matches.; SMD0805P050TF: Higher trip current reduces protection. | |
| Temperature | -40°C to +85°C | -40°C to +85°C | - | -40°C to +85°C — Operating temperature range matches. | |
| Resistance | 1.20Ω | - | 0.85Ω | 0.85Ω — Lower max resistance is an improvement. |
Verified drop-in options for MF-PSMF035X-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.
