Is there a pin-compatible replacement for KNP2W-22Ω±5% T?

No pin-for-pin compatible replacement has been verified. Candidates like MFR03SF220JA10 have a different technology (metal film), and KNP5WS-20Ω±5% T has a different size and resistance.

What risks should I check before replacing KNP2W-22Ω±5% T?

Key risks include: 1) Technology: Metal film substitutes have different inductance and pulse handling than wirewound. 2) Resistance: Ensure the new value is within your circuit's tolerance. 3) Physical Size: Higher power resistors are often larger.

AI replacement insight

Package riskhigh

Some alternatives are physically larger or have different mounting types.

Electrical riskmedium

Technology and resistance differences require circuit analysis.

Can it be replaced directly?

No direct drop-in replacement was found. All candidates require review for parametric, technological, or physical differences.

Best replacement path

Consider parts from the same KNP series with higher power ratings if space allows, but verify resistance. For different technologies, electrical validation is critical.

Main risk

The primary risks are technology mismatch (affecting inductance and pulse response) and physical size differences.

Recommended alternatives

A 22Ω axial resistor with higher power (3W) and tighter tolerance (1%), but uses Metal Film technology.
