What risks should I check before replacing FRC1206J821 TS?

When replacing FRC1206J821 TS, verify that the substitute's power rating (0.25W), voltage rating (200V), and temperature coefficient (±100 ppm/°C) are sufficient for your application. If considering a part with different resistance, confirm the impact on circuit performance.

FRC1206J821 TS Alternatives, Datasheet & Cross Reference | FOJAN

FRC1206J821 TS is a general-purpose 820Ω, 5% tolerance, 0.25W resistor in a 1206 package. Several alternatives exist, including upgrades to 1% tolerance and options with different resistance values that may be suitable after engineering review.

AI replacement insight

Electrical risklow

Low if key parameters (Resistance, Power, TCR) are matched or improved. Medium if resistance is changed.

Package risklow

All suggested candidates are in the same 1206 package.

Sourcing risklow

This is a common resistor value available from multiple manufacturers.

Can it be replaced directly?

Direct replacement for FRC1206J821 TS should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.

Best replacement path

The safest replacement path is choosing a part with identical or better specifications, such as Yageo's RC1206FR-07820RL, which offers a tighter tolerance.

Main risk

The main risk is using a substitute with unverified or mismatched parameters, such as a different resistance value or temperature coefficient (TCR), which could alter circuit behavior.

Recommended alternatives

An excellent alternative from the same manufacturer with an improved tolerance of ±1%.
