Is there a pin-compatible replacement for 1206W4F110KT5E?

No exact pin-to-pin replacement with identical key parameters was identified. Candidates like HP06W2F120KT5E and CRCW12061R00FKEAHP share the 1206 package but have slightly different resistance values that require engineering review.

What risks should I check before replacing 1206W4F110KT5E?

The main risk is the resistance difference; available substitutes are 1.0Ω or 1.2Ω, not 1.1Ω. Verify if your circuit can tolerate this ~9% deviation. Also check for functional differences, as some alternatives are specialized (e.g., current-sense).

1206W4F110KT5E Alternatives, Datasheet & Cross Reference | UNI-ROYAL

Finding a substitute for the 1206W4F110KT5E resistor involves balancing resistance value with power rating. Several alternatives exist with higher power ratings, but require checking circuit tolerance for a ~9% resistance difference.

AI replacement insight

Electrical riskmedium

Resistance differs by ~9%, requiring circuit tolerance analysis.

Package risklow

All recommended alternatives use the same 1206 package.

Can it be replaced directly?

No direct, drop-in replacement was found. All viable options require review due to resistance mismatch.

Best replacement path

Use CRCW12061R00FKEAHP for an upgrade in power and reliability, provided the 9% lower resistance is acceptable.

Main risk

Resistance mismatch. All strong candidates have a resistance of 1.0Ω or 1.2Ω, differing from the target's 1.1Ω.

Recommended alternatives

AEC-Q200 qualified 1206 resistor with much higher power (0.75W) but slightly lower resistance (1.0Ω).
