Is there a pin-compatible replacement for SST1200?

Yes, other fuses in the REOMAX SST series, such as SST1150 and SST1500, share the same 6125 (2410) package and are pin-compatible. However, their electrical parameters, specifically the current rating, are different and require engineering review.

What risks should I check before replacing SST1200?

The primary risk is the current rating. Using a higher-rated fuse (e.g., 5A) will not protect the circuit as intended. Using a lower-rated fuse (e.g., 1.5A) may cause it to blow during normal operation. Always verify the replacement's current rating, voltage rating (AC/DC), and time-current curve.

SST1200 Alternatives, Datasheet & Cross Reference | Dongguan Reomax Electronics Co., Ltd.

The REOMAX SST1200 is a 2A, 300VAC slow-blow fuse in a 6125 (2410) package. Alternatives exist within the same SST series, but require careful review of the current rating before substitution.

AI replacement insight

Electrical riskhigh

Current rating mismatch is a critical safety parameter for fuses.

Package risklow

Viable candidates share the same 6125 (2410) package.

Can it be replaced directly?

No direct 1-to-1 replacement has been identified. All candidates have different current ratings, posing either a safety or operational risk.

Best replacement path

Evaluate if the circuit's maximum steady current is below 1.5A, making SST1150 a viable, safer option. Otherwise, a redesign may be needed.

Main risk

Mismatched current rating. Using a higher value negates circuit protection, while a lower value may cause nuisance tripping.

Recommended alternatives

Form-fit compatible but has a higher 5A current rating, requiring careful engineering review before use.

Questions & answers

There is no direct drop-in replacement. The closest options are other fuses in the REOMAX SST series, like SST1150 (1.5A) or SST1500 (5A), but the current rating difference must be evaluated for your specific application to avoid safety issues or nuisance tripping.
