Is there a pin-compatible replacement for FTR1206-150?

Yes, several PTC fuses in the same 1206 package exist, such as BSMD1206-150-16V. While the package is identical, critical parameters like max fault current differ, requiring engineering review before considering it a drop-in replacement.

What risks should I check before replacing FTR1206-150?

The primary risk is the maximum fault current (Imax). The target is rated for 100A, while many alternatives are rated lower (40A-50A). Ensure the replacement's Imax is sufficient for your circuit's worst-case fault conditions.

FTR1206-150 Alternatives, Datasheet & Cross Reference | FTR Qiaoguang

Finding a substitute for the FTR1206-150 PTC fuse involves matching its 1206 package, 1.5A hold current, and 3A trip current. Key alternatives offer higher voltage ratings but may have different max fault current capabilities.

AI replacement insight

Electrical riskmedium

Lower max fault current (Imax) on all candidates.

Package risklow

All candidates share the same 1206 package.

Can it be replaced directly?

No direct drop-in replacement is confirmed. While several parts match form and primary function, they have a lower maximum fault current rating that requires engineering validation.

Best replacement path

BSMD1206-150-16V or SMD1206-150C-16V, pending fault current analysis.

Main risk

The replacement part may fail if the circuit's potential fault current exceeds the candidate's lower Imax rating.

Recommended alternatives

A 1206 PTC fuse with matching hold current and higher voltage, but a much lower max fault current rating.
