Is there a pin-compatible replacement for RC0603FR-07680KL?

Yes, there are pin-compatible 0603 resistors, but they may have slightly different resistance values (e.g., 620kΩ). Exact 680kΩ matches from other vendors should be verified for all key parameters.

What risks should I check before replacing RC0603FR-07680KL?

Key risks include package size mismatch requiring PCB changes, and resistance deviation affecting circuit performance. Always verify the candidate's power rating, tolerance, and temperature coefficient (TCR).

RC0603FR-07680KL Alternatives, Datasheet & Cross Reference | Yageo

Finding a substitute for the Yageo RC0603FR-07680KL, a 680kΩ 1% 0.1W 0603 resistor, involves checking package size, resistance, and power rating. Alternatives may require design adjustments.

AI replacement insight

Electrical riskmedium

Resistance may deviate, requiring circuit analysis.

Package riskhigh

Some candidates have a different package (0805 vs 0603), making them not drop-in.

Sourcing risklow

This is a common resistor value and package, with many potential vendors.

Can it be replaced directly?

No direct, one-to-one replacement was identified without caveats. The closest options have either a different package size or a slightly different resistance value.

Best replacement path

If the PCB layout is fixed, find a 0603 resistor with resistance as close to 680kΩ as possible. If the layout can be modified, a functional match in a different package like 0805 is an option.

Main risk

The main risks are physical incompatibility due to package size differences and functional deviation from resistance mismatch.

Recommended alternatives

Parametric alternative in the same 0603 package but with a lower resistance of 620kΩ.

Questions & answers

The best alternative depends on design flexibility. For the same 0603 footprint, parts with slightly different resistance like 620kΩ may work if the circuit allows. If layout can change, 0805 parts with identical electricals are available.
