Parameter Comparison

Engineering Selection Recommendations

RC1608F3R0CS (Samsung Electro-Mechanics) is suitable for general-purpose applications requiring 3 Ohm ±1% 0.1W 0603 resistors with moisture resistant characteristics. The component carries ROHS3 compliance and unlimited MSL rating, supporting standard industrial and consumer electronics applications.

KTR03EZPF3R00 (Rohm Semiconductor) provides an equivalent substitute with automotive AEC-Q200 qualification. This variant features a lower temperature coefficient (±200ppm/°C versus ±300ppm/°C), offering improved temperature stability. Selection is appropriate for automotive applications or designs requiring enhanced reliability certification.

RMCF0603FT3R00 (Stackpole Electronics Inc) provides an equivalent substitute with automotive AEC-Q200 qualification and ±200ppm/°C temperature coefficient. Physical dimensions show a minor length variation (0.061" versus 0.063"), which remains within standard 0603 package tolerances. Selection is appropriate for automotive applications or designs requiring enhanced reliability certification.

All three parts maintain identical electrical specifications (3 Ohms ±1%, 0.1W), operating temperature range (-55°C ~ 155°C), package classification (0603), and regulatory compliance (ROHS3, REACH Unaffected). Selection between these parts depends on application requirements for automotive qualification and temperature coefficient performance.

Frequently Asked Questions (FAQ)

Q: Can KTR03EZPF3R00 or RMCF0603FT3R00 be used as direct replacements for RC1608F3R0CS?

A: Yes. Both substitute parts meet all primary electrical and mechanical specifications: 3 Ohms ±1%, 0.1W power rating, 0603 package, thick film composition, -55°C ~ 155°C operating range, and ROHS3 compliance. Physical dimensions and termination count are identical or within standard package tolerances.

Q: What is the difference in temperature coefficient between the main part and substitutes?

A: The RC1608F3R0CS has a temperature coefficient of ±300ppm/°C. Both KTR03EZPF3R00 and RMCF0603FT3R00 have ±200ppm/°C temperature coefficients, indicating superior temperature stability. This difference is significant only in applications with strict temperature-dependent resistance requirements.

Q: Are the substitute parts suitable for automotive applications?

A: KTR03EZPF3R00 and RMCF0603FT3R00 carry AEC-Q200 automotive qualification. The RC1608F3R0CS does not specify automotive qualification. For automotive applications, KTR03EZPF3R00 or RMCF0603FT3R00 are the appropriate selections.

Q: Is there a physical dimension difference between RMCF0603FT3R00 and the other parts?

A: RMCF0603FT3R00 has a length of 0.061" (1.55mm) compared to 0.063" (1.60mm) for RC1608F3R0CS and KTR03EZPF3R00. This 0.05mm difference is within standard 0603 package tolerances and does not affect PCB layout or assembly compatibility.

Q: Do all three parts have the same moisture sensitivity level?

A: Yes. All three parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions for storage, handling, or reflow processes.

Q: What is the inventory availability for each part?

A: RC1608F3R0CS: 980 Pcs. KTR03EZPF3R00: 56,387 Pcs. RMCF0603FT3R00: 48,030 Pcs. Substitute parts offer significantly higher inventory availability.

Q: Are all parts ROHS3 compliant?

A: Yes. RC1608F3R0CS, KTR03EZPF3R00, and RMCF0603FT3R00 are all ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.
