0402 is a standard, widely available package.

Sourcing riskmedium

FOJAN is a smaller brand; alternatives from larger manufacturers like Yageo may be more available.

Can it be replaced directly?

Yageo's RT0402BRD079K1L is a strong upgrade. For a like-for-like thick film part, FH's RC-02K9101FT is very similar but has a lower max operating temp.

Best replacement path

Upgrade to a thin film resistor like Yageo RT0402BRD079K1L for better precision and stability.

Main risk

The primary risk is ensuring the substitute's operating temperature range meets or exceeds the original part's -55°C to +155°C specification.

Recommended alternatives

Yageo RT0402BRD079K1L is a high-precision upgrade with tighter tolerance and TCR in the same 0402 package.
