Strong functional match with identical hold/trip current and package, but lower power rating.
Finding a replacement for the BNstar SMD0805-200-6V PTC fuse requires matching the 0805 package, 6V rating, and critical 2.0A hold current. Several alternatives exist with varying parametric alignment.
Candidate current and power ratings must be carefully verified to ensure proper circuit protection.
The 0805 package is standardized, minimizing physical compatibility issues.
No verified drop-in replacement found. JK-SMD-0805-200L is a strong form-fit-function match, but its lower power rating requires engineering review.
JK-SMD-0805-200L is the strongest candidate, matching key electricals and package, but has lower power dissipation.
The primary risk is using a part with a higher hold current, which would fail to protect the downstream circuit as intended.

| Feature / factor | SMD0805-200-6V | JK-SMD-0805-200L | BSMD0805L-260 | Alt 3 | Compatibility / risk |
|---|---|---|---|---|---|
| Package | 0805 | 0805 | 0805 | 0805 — Form and fit match.; BSMD0805L-260: Form and fit match. | |
| Current | 4.0 A | 4.0 A | 5.2 A | 4.0 A / 5.2 A — Trip current matches.; BSMD0805L-260: Higher trip current reduces protection. | |
| Voltage | 6.0 V | 6.0 V | 6.0 V | 6.0 V — Max voltage matches.; BSMD0805L-260: Max voltage matches. | |
| Power | 1.0 W | 0.7 W | 1.2 W | 0.7 W / 1.2 W — Lower power dissipation requires review.; BSMD0805L-260: Higher power dissipation is acceptable. |
JK-SMD-0805-200L by Jinrui is the best functional alternative, matching the 2.0A hold current, 6V rating, and 0805 package. However, its lower power dissipation (0.7W vs 1.0W) must be verified for your application.
