AI replacement insight

Electrical risklow

Low if using a replacement with an equal or higher power rating. Verify TCR for sensitive applications.

Package risklow

The 0402 package is standardized, ensuring form and fit compatibility.

Can it be replaced directly?

Yes, several direct replacements exist. The Yageo RC0402FR-7W100KL is a strong candidate with a higher power rating, making it a safer choice.

Best replacement path

Upgrade to a higher power rated part like Yageo RC0402FR-7W100KL (1/8W) or the high-reliability Vishay CRCW0402100KFKEDHP (0.2W).

Main risk

The primary risk is using a part with an insufficient power rating. Ensure any substitute has a power rating of at least 0.1W (1/10W) for improved reliability.

Recommended alternatives

This UNI ROYAL resistor is a 100kΩ 1% 0402 part with an increased power rating of 1/10W, suitable as an upgrade.
