Is there a pin-compatible replacement for FRC0805F1651TS?

Yes, several 0805 package resistors are pin-compatible. FRC0805F1601TS and RC0805FR-071K6L are strong candidates, but you must verify if the 3% lower resistance (1.6kΩ vs 1.65kΩ) is acceptable for your application.

What risks should I check before replacing FRC0805F1651TS?

The main risk is the resistance value. The target is 1.65kΩ; most common substitutes are 1.6kΩ. Verify your circuit's sensitivity to this -3% change. Also, ensure the replacement has the same or better power, tolerance, and TCR ratings.

FRC0805F1651TS Alternatives, Datasheet & Cross Reference | FOJAN

FRC0805F1651TS is a general-purpose 1.65kΩ 1% 0.125W resistor in an 0805 package. Alternatives with the more common 1.6kΩ resistance value are readily available and suitable for most applications.

AI replacement insight

Electrical risklow

Resistance differs by only -3%, which is acceptable in most general-purpose circuits.

Package risklow

All recommended alternatives are in the same 0805 package.

Can it be replaced directly?

No exact direct replacement is commonly stocked. The closest options are 1.6kΩ resistors like FRC0805F1601TS, which require verifying the resistance change is acceptable.

Best replacement path

Use FRC0805F1601TS for a same-manufacturer alternative or RC0805FR-071K6L for a cross-vendor option, accepting a -3% resistance change.

Main risk

The primary risk is the resistance deviation from the target's 1.65kΩ value.

Recommended alternatives

Same manufacturer and series with a 3% lower resistance value; all other parameters match.
