Finding a replacement for the Yageo MFR2WSFTF73-1R, a 2W 1Ω axial resistor, involves matching power, resistance, tolerance, and package. Several options exist with varying degrees of compatibility.

AI replacement insight

Electrical risklow

Low for matched parts, medium for parts with wider tolerance.

Package risklow

Low for axial-to-axial, but always verify physical dimensions.

Sourcing risklow

These are common resistor values from multiple vendors.

Can it be replaced directly?

Direct replacement for MFR2WSFTF73-1R should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.

Best replacement path

The most direct path is CCO's MF2WS-1Ω±1% T, which is electrically identical. For higher power needs, MOF5WS-1Ω±5% T is an option if the wider tolerance is acceptable.

Main risk

The main risk is using a part with wider tolerance (e.g., ±5%), which can affect performance in precision circuits.
