Is there a pin-compatible replacement for SL0805150?

While several alternatives share the same 0805 package and are physically pin-compatible, none are electrically equivalent. All reviewed candidates have a higher hold current, which is a critical safety parameter.

What risks should I check before replacing SL0805150?

The main risk is inadequate overcurrent protection. A replacement with a higher hold current (e.g., 2.0A instead of 1.5A) will not trip under the same fault conditions, potentially damaging the circuit it's meant to protect. Always verify the new trip characteristics against your design's safety requirements.

SL0805150 Alternatives, Datasheet & Cross Reference | TECHFUSE

TECHFUSE SL0805150 is a 1.5A hold current PTC resettable fuse in an 0805 package. While alternatives in the same package exist, they typically feature higher current ratings, requiring careful engineering review to ensure proper circuit protection.

AI replacement insight

Electrical riskhigh

All candidates have higher hold/trip currents, altering the circuit's protection characteristics.

Package risklow

All candidates share the same 0805 package, ensuring physical compatibility.

Can it be replaced directly?

There are no direct, drop-in replacements for SL0805150 among the candidates reviewed. All have different current ratings.

Best replacement path

No direct replacement was found. The closest options have a higher hold current (2.0A vs 1.5A), such as SMD0805-200-6V. This change requires careful circuit analysis.

Main risk

The primary risk is reduced circuit protection due to higher hold and trip currents, which could lead to downstream component damage under fault conditions.

Recommended alternatives

Functional alternative in an 0805 package, but with a higher hold current that requires engineering review.
