FOJAN
A 2W power upgrade from the same manufacturer with identical resistance, tolerance, and 2512 package.
Find and compare replacements for the FRC2512J181 TS, a 180Ω 1W 5% 2512 thick film resistor. Key parameters for substitutes include power rating, tolerance, and package size.
Key parameters match or are improved.
All viable candidates use the same 2512 package.
Direct replacement for FRC2512J181 TS should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
Upgrade to the higher-power FRP2512J181 TS from the same manufacturer for maximum compatibility and improved thermal margin.
The primary risk is ensuring the substitute's power derating curve meets or exceeds the original part's performance in the application's thermal environment.
