BNstar
A potential alternative in the same 1206 package with a higher voltage rating, but requires review of its higher hold current.
Finding a substitute for the TECHFUSE nSMD035-16V PTC fuse requires matching its 16V, 0.35A hold current, and 1206 package. Alternatives may require careful review of their hold current.
Mismatched hold current is the primary concern.
All candidates use the same 1206 package.
Qualifying alternatives improves supply chain resilience.
No direct, fully equivalent replacement was found in this batch. All viable candidates have a higher hold current, requiring design review.
Seek a PTC fuse with Ihold as close to 0.35A as possible. The BNstar SMD1206-050C series is a starting point for review.
Circuit damage due to inadequate overcurrent protection from a substitute with a higher hold current.

| Feature / factor | nSMD035-16V | SMD1206-050C-24V | SMD1206-050C-30V | SMD1206-075C-30V | Compatibility / risk |
|---|---|---|---|---|---|
| Package | 1206 | 1206 | 1206 | 1206 | 1206 — Same package and pin count.; SMD1206-050C-30V: Same package and pin count.; SMD1206-075C-30V: Same package and pin count. |
| Voltage | 16V | 24V | 30V | 30V | 24V / 30V — Higher voltage rating is a safe upgrade.; SMD1206-050C-30V: Higher voltage rating is a safe upgrade.; SMD1206-075C-30V: Higher voltage rating is a safe upgrade. |
| Current | 0.35A | 0.5A | 0.5A | 0.75A | 0.5A / 0.75A — Higher hold current reduces protection level.; SMD1206-050C-30V: Higher hold current reduces protection level.; SMD1206-075C-30V: Hold current is >2x target, poses high risk. |
| Resistance | 0.25Ω / 1.30Ω | - | 0.15Ω / 0.70Ω | - | 0.15Ω / 0.70Ω — Lower initial resistance (Rmin/R1max). |
Parts like BNstar's SMD1206-050C-24V are potential alternatives. They share the 1206 package and have a higher voltage rating, but their hold current is higher (0.5A vs 0.35A), which requires engineering validation.
