TECHFUSE
Strong cross-vendor alternative from TECHFUSE with matching package, voltage, and current ratings.
Finding a substitute for the Jinrui JK-SMD1210-005-60V PTC fuse involves matching its 1210 package, 60V voltage rating, and 50mA hold current. Several alternatives exist with varying degrees of compatibility.
For SMD1210-005-60V, key specs match. For other parts, current/voltage mismatches are high risk.
All candidates share the same 1210 package, ensuring physical compatibility.
Direct replacement for JK-SMD1210-005-60V should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
The strongest alternative is TECHFUSE SMD1210-005-60V, which matches all key electrical and physical parameters.
The primary risk when substituting PTC fuses is a mismatch in hold/trip current or voltage rating, which can lead to inadequate circuit protection or device failure.

| Feature / factor | JK-SMD1210-005-60V | SMD1210-005-60V | SMD1210-010-60V | Alt 3 | Compatibility / risk |
|---|---|---|---|---|---|
| Package | 1210 | 1210 | 1210 | 1210 — Same SMD package size.; SMD1210-010-60V: Same SMD package size. | |
| Voltage | 60V | 60V | 60V | 60V — Maximum voltage rating matches.; SMD1210-010-60V: Maximum voltage rating matches. | |
| Current | 150mA | 150mA | 300mA | 150mA / 300mA — Trip current (Itrip) matches.; SMD1210-010-60V: Higher trip current allows more overcurrent before tripping. | |
