AI replacement insight
Electrical riskhigh
Technology mismatch (Wirewound vs. Film/Oxide) affects pulse handling and failure modes.
Package riskmedium
One candidate has a non-matching Radial package, preventing drop-in use.
Sourcing risklow
Multiple alternatives exist from various manufacturers.
Can it be replaced directly?
No direct drop-in replacement has been verified. All candidates have significant differences in technology, package, or operating parameters that require engineering review.
Best replacement path
MOF3WS-47Ω±5% T offers an upgraded power rating with identical resistance, but requires verifying if Metal Oxide technology is suitable for the application.
Main risk
The primary risk is the change in resistor technology from Wirewound to Metal Oxide or Metal Film, which can impact performance in high-pulse or high-reliability applications.
