Is there a pin-compatible replacement for MF2WS-20Ω±1% T?

No replacement has been fully verified as pin-compatible. Candidates like CPF320R000FKE14 are claimed to be Axial and match key specs, but require a full datasheet review to confirm pin-to-pin compatibility.

What risks should I check before replacing MF2WS-20Ω±1% T?

Key risks include changes in resistance value (e.g., 22Ω vs 20Ω), wider tolerance (±5% vs ±1%), and different temperature coefficient (TCR). Also, verify the physical dimensions of the axial package to ensure it fits your PCB layout.

MF2WS-20Ω±1% T Alternatives, Datasheet & Cross Reference | CCO

Finding a substitute for the CCO MF2WS-20Ω±1% T resistor involves balancing power, tolerance, and resistance. Alternatives exist with higher power ratings, but may have different resistance values or tolerances requiring circuit review.

AI replacement insight

Electrical riskmedium

Candidates may have different resistance, tolerance, or TCR.

Package risklow

Most alternatives are Axial, but physical dimensions must always be verified.

Sourcing risklow

Multiple cross-vendor options appear to be available.

Can it be replaced directly?

No verified direct pin-to-pin replacement is currently cataloged. Candidates like Vishay's CPF320R000FKE14 appear to be strong functional matches but require datasheet verification before use.

Best replacement path

Use an external candidate like Vishay's PR03000202009FAC00, which offers upgraded power (3W) and AEC-Q200 qualification with matching resistance and tolerance, pending datasheet verification.

Main risk

The main risk is substituting with a part that has a different resistance value (e.g., 22Ω) or a wider tolerance (e.g., 5%), which can affect circuit performance.

Recommended alternatives

A functional alternative with higher power (3W) and same tolerance, but resistance is 10% higher at 22Ω.
