TECHFUSE
A strong alternative in the same 0805 package with identical hold/trip currents and a higher voltage rating.
Find replacements for the Littelfuse 0805L010YR PTC fuse. This 0.1A, 15V, 0805 device has several potential alternatives, with TECHFUSE SMD0805-010-33V being a strong candidate.
The best candidate (SMD0805-010-33V) matches key electricals. Other candidates pose a high electrical risk.
All reviewed candidates use the same 0805 package, ensuring form-fit compatibility.
Availability and lead time for alternatives should be verified with distributors.
Direct replacement for 0805L010YR should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
The most direct replacement path is TECHFUSE SMD0805-010-33V, which matches critical current and resistance ratings.
The primary risk is using a substitute with a higher hold current, which would leave the circuit unprotected at its designed limit.
