AI replacement insight

Electrical riskmedium

Several candidates have different resistance values or technology (thin film).

Package risklow

All reviewed candidates use the same 0603 package.

Sourcing risklow

Alternatives are from different manufacturers, which may have varying supply chain stability.

Can it be replaced directly?

Yes, RS-03K2101FT by FH is a strong candidate for a direct replacement, matching all critical electrical and physical parameters.

Best replacement path

The most direct path is RS-03K2101FT, which matches all key specifications. For higher precision, consider the thin-film upgrade RT0603BRD072K1L, but verify application suitability.

Main risk

The main risk when substituting is using a part with a different resistance value, which can alter circuit behavior. A secondary risk is the technology mismatch (thin vs. thick film).
