What risks should I check before replacing SCR0603F68K?

The main risks are electrical. Check if the substitute's resistance tolerance (e.g., ±5% vs ±1%) is acceptable for your circuit. Also, verify if minor differences in resistance value (e.g., 68.1kΩ vs 68kΩ) are within your design's limits.

SCR0603F68K Alternatives, Datasheet & Cross Reference | EVVO

SCR0603F68K is a general-purpose 0603 thick film chip resistor with 68kΩ resistance and ±1% tolerance. Several pin-compatible and parametric alternatives are available from various manufacturers.

AI replacement insight

Electrical riskmedium

Risk is medium if selecting a part with wider tolerance (5%) or different resistance. Risk is low for 1% exact matches.

Package risklow

All reviewed candidates use the same standard 0603 package, ensuring physical compatibility.

Sourcing risklow

This is a common resistor value with many alternatives available from multiple manufacturers.

Can it be replaced directly?

Direct replacement for SCR0603F68K should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.

Best replacement path

Use an AEC-Q200 qualified part like Yageo's AC0603FR-0768KL for an exact parametric match with higher reliability.

Main risk

The main risk is using a substitute with a wider tolerance (e.g., 5% vs 1%), which can impact the performance of precision circuits.

Recommended alternatives

Automotive-grade (AEC-Q200) substitute with identical key parameters and package.
