A pin-compatible PTC fuse with a slightly higher hold current (1.85A); requires engineering review.
JK60-160 is a 60V, 1.6A PTC resettable fuse in a radial leaded package. When seeking a replacement, focus on matching the hold current, trip current, and voltage rating to ensure proper circuit protection.
Substitutes have higher hold currents, which may not provide adequate protection.
All viable candidates share the same radial leaded package, ensuring form-fit compatibility.
Direct replacement for JK60-160 should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
The best replacement path is selecting another PTC from the JK60 series with a hold current as close as possible to 1.6A, such as the JK60-185.
The main risk is selecting a substitute with a higher hold current, which can compromise circuit protection by allowing excessive current before tripping.

| Feature / factor | JK60-160 | JK60-185 | JK60-200 | Alt 3 | Compatibility / risk |
|---|---|---|---|---|---|
| Package | Radial Leaded | Radial Leaded | Radial Leaded | Radial Leaded — Same form factor.; JK60-200: Same form factor. | |
| Voltage | 60.0V | 60.0V | 60.0V | 60.0V — Voltage rating is identical.; JK60-200: Voltage rating is identical. | |
| Current | 3.2A | 3.7A | 2.0A | 3.7A / 2.0A — Trip current is higher.; JK60-200: Hold current is 25% higher. |
Verified drop-in options for JK60-160 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.
