Strong alternative from TECHFUSE with matching package, voltage, and current ratings.
SMD1812-200C-16V is a 16V, 2.0A PTC resettable fuse in an 1812 package. This page provides verified alternatives, including pin-compatible options and upgrades with higher voltage ratings.
High if hold current is not matched. Low for matched candidates.
All reviewed candidates use the same 1812 package.
Multiple vendors offer parts with similar specifications.
Direct replacement for SMD1812-200C-16V should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
mSMD200-16V from TECHFUSE offers a near-identical parametric match. For enhanced voltage tolerance, consider ASMD1812-200-30V.
The main risk is using a part with a higher hold current (e.g., 2.6A), which may not provide adequate overcurrent protection for the original design.

| Feature / factor | SMD1812-200C-16V | ASMD1812-200-30V | mSMD200-16V | SMD1812-260C-24V | Compatibility / risk |
|---|---|---|---|---|---|
| Package | 1812 | 1812 | 1812 | 1812 | 1812 — Same package size ensures form-fit compatibility.; mSMD200-16V: Same package size ensures form-fit compatibility.; SMD1812-260C-24V: Same package size. |
| Voltage | 16.0V | 30.0V | 16.0V | 24.0V | 30.0V / 16.0V / 24.0V — Higher voltage rating provides increased design margin.; mSMD200-16V: Maximum voltage rating is identical.; SMD1812-260C-24V: Higher voltage rating provides more margin. |
| Current | 4.0A | 4.0A | 4.0A | 2.6A | 4.0A / 2.6A — Trip current (It) is identical.; mSMD200-16V: Trip current (It) is identical.; SMD1812-260C-24V: Hold current is 30% higher, may not provide sufficient protection. |
| Power | 0.8W | - | 0.8W | - | 0.8W — Typical power dissipation is identical. |
Verified drop-in options for SMD1812-200C-16V 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.
