Is there a pin-compatible replacement for MF-NSMF110-2?

Yes, parts from the Bourns MF-NSMF series like MF-NSMF150-2 are in the same 1206 package and are pin-compatible. However, their electrical parameters, especially hold current, differ and must be verified.

What risks should I check before replacing MF-NSMF110-2?

The primary risk is a mismatch in hold current. Using a replacement with a higher hold current will allow more current to pass before tripping, potentially exposing downstream components to damage. Always verify the new protection level is acceptable for your design.

MF-NSMF110-2 Alternatives, Datasheet & Cross Reference | BOURNS

MF-NSMF110-2 is a 1.1A, 6V resettable PPTC fuse in a 1206 package. Key alternatives exist within the same Bourns MF-NSMF series, but require careful review of hold current ratings.

AI replacement insight

Electrical riskmedium

Hold current mismatch requires design review.

Package risklow

Candidates share the same 1206 package.

Can it be replaced directly?

No direct drop-in replacement with identical specs is listed. MF-NSMF150-2 is the closest option but requires engineering review due to a different hold current.

Best replacement path

Use MF-NSMF150-2 as a close functional alternative, verifying the impact of the increased 1.5A hold current.

Main risk

The main risk is reduced overcurrent protection sensitivity from using a substitute with a higher hold current.

Recommended alternatives

A functional alternative in the same 1206 package and 6V rating, but with a higher 1.5A hold current.
