What risks should I check before replacing 1206W4F110LT5E?

First, verify the Temperature Coefficient (TCR) of the replacement matches the ±100 PPM/°C of the original. Second, check if your circuit can tolerate small resistance variations (e.g., 0.1Ω instead of 0.11Ω). Finally, ensure the power rating is equal or greater.

1206W4F110LT5E Alternatives, Datasheet & Cross Reference | UNI-ROYAL

The 1206W4F110LT5E is a 0.11Ω, 1% tolerance, 0.25W thick film chip resistor in a 1206 package. This review identifies several potential alternatives for current sensing and power management, with considerations for resistance, power, and temperature coefficient (TCR).

AI replacement insight

Electrical riskmedium

TCR mismatch is a key concern for precision circuits. Resistance values differ in some candidates.

Package risklow

All suggested alternatives use the same 1206 package.

Sourcing risklow

Multiple alternatives from different manufacturers are available.

Can it be replaced directly?

FRL1206FR110TS is the closest match, sharing the same resistance, power, tolerance, and package. However, its Temperature Coefficient of Resistance (TCR) is not specified and must be verified.

Best replacement path

FRL1206FR110TS offers identical resistance but requires TCR verification. For an upgrade, PE1206FRF470R1L provides higher power and matched TCR, with a minor resistance difference.

Main risk

The primary risk is a mismatched Temperature Coefficient (TCR), which can affect circuit stability. A secondary risk is the slight resistance mismatch in some alternatives.

Recommended alternatives

Potential pin-compatible part with identical resistance and power; requires TCR verification.
