Frequently Asked Questions (FAQ)

Q: Can RC0603JR-0791KL directly replace RC1608J913CS without PCB modification?

A: Yes. Both parts share identical 0603 (1608 Metric) package dimensions, electrical specifications (91 kOhms ±5%, 0.1W), and operating temperature range (-55°C ~ 155°C). Direct substitution on existing PCB layouts is supported.

Q: What is the difference between ±5% and ±1% tolerance parts?

A: Tolerance defines the maximum deviation from the nominal 91 kOhm resistance value. ±5% tolerance allows deviation up to ±4.55 kOhms; ±1% tolerance restricts deviation to ±0.91 kOhms. ±1% parts provide superior accuracy for precision circuits but are electrically compatible with ±5% designs.

Q: Are AEC-Q200 rated parts suitable for non-automotive applications?

A: Yes. AEC-Q200 certification indicates enhanced reliability testing and qualification. These parts exceed standard industrial requirements and are fully compatible with general-purpose applications.

Q: What is the significance of temperature coefficient (ppm/°C)?

A: Temperature coefficient indicates resistance value change per degree Celsius. ±100ppm/°C means 0.01% change per °C; ±200ppm/°C means 0.02% change per °C. Lower values provide better stability across temperature extremes.

Q: Does packaging format (Tape & Reel vs. Cut Tape) affect electrical performance?

A: No. Packaging format affects only supply and handling logistics. Tape & Reel (TR) and Cut Tape (CT) & Digi-Reel® formats contain identical components with identical electrical characteristics.

Q: Can I use RMCF0603FT91K0 in place of RC1608J913CS?

A: Yes. RMCF0603FT91K0 is electrically compatible with superior ±1% tolerance and AEC-Q200 automotive qualification. It maintains identical package dimensions and operating temperature range.

Q: What does Moisture Sensitivity Level (MSL) 1 mean?

A: MSL 1 indicates unlimited shelf life without moisture baking requirements. The component is not sensitive to moisture absorption during storage and handling.

Q: Are all listed substitute parts ROHS3 compliant?

A: Yes. All substitute parts listed maintain ROHS3 compliance, matching the environmental certification of the original RC1608J913CS.
