A higher voltage version with identical current ratings and package from the same manufacturer.
BSMD0603-050-6V is a 6V, 0.5A PTC resettable fuse in a common 0603 package. Excellent alternatives exist, primarily offering higher voltage ratings for improved robustness, or functional alternatives with different current thresholds for specific needs.
Risk is high if an alternate with a different current rating is chosen without review.
All top candidates share the same 0603 package.
Multiple suitable alternatives are available from the same and other manufacturers.
Yes, BSMD0603-050-16V is an excellent replacement, offering a higher 16V rating with the same 0.5A hold current and 0603 package.
Use BSMD0603-050-16V or BSMD0603-050-12V for a direct upgrade with a higher voltage tolerance.
The main risk is choosing a part with a higher hold current, which will not protect the circuit at the intended level.

| Feature / factor | BSMD0603-050-6V | BSMD0603-050-16V | BSMD0603-050-12V | BSMD0603-075-6V | Compatibility / risk |
|---|---|---|---|---|---|
| Package | 0603 | 0603 | - | - | 0603 — Identical package. |
| Voltage | 6V | 16V | - | - | 6V — Identical voltage rating. |
| Current | 0.5A | 1A | - | - | 1.5A — Higher trip current. |
The best alternative is BSMD0603-050-16V. It has the same manufacturer, package, and current ratings, but offers a higher voltage rating (16V vs 6V) for increased design margin.
