Parameter Comparison

Engineering Selection Recommendations

RC1608F3484CS (Samsung Electro-Mechanics): Primary selection for applications without automotive qualification requirements. ROHS3 Compliant and REACH Unaffected. Moisture Sensitivity Level 1 provides unlimited shelf life. Temperature coefficient of ±100ppm/°C supports precision applications within the -55°C to 155°C operating range.

RMCF0603FT3M48 (Stackpole Electronics Inc): Qualified substitute with AEC-Q200 automotive certification. Suitable for automotive and industrial applications requiring automotive-grade component qualification. Temperature coefficient of ±200ppm/°C is within acceptable tolerance for this resistor category. Significantly higher inventory availability (27807 Pcs) supports high-volume production requirements.

CRCW06033M48FKEA (Vishay Dale): Qualified substitute with AEC-Q200 automotive certification. Equivalent temperature coefficient of ±100ppm/°C matches the primary part specification. Suitable for automotive and industrial applications. High inventory availability (24763 Pcs) supports production continuity. Physical dimensions (1.55mm x 0.85mm) remain within 0603 package specification tolerance.

All three parts are Active product status with ROHS3 compliance and REACH Unaffected designation, confirming regulatory compliance for current manufacturing standards.

Frequently Asked Questions (FAQ)

Q: Can RMCF0603FT3M48 replace RC1608F3484CS in non-automotive applications?

A: Yes. The RMCF0603FT3M48 meets all electrical and mechanical parameters of the RC1608F3484CS. The AEC-Q200 automotive qualification is an additional feature that does not restrict use in general-purpose applications. The ±200ppm/°C temperature coefficient remains within acceptable tolerance for 0603 thick film resistor applications.

Q: What is the difference between the temperature coefficients of these parts?

A: RC1608F3484CS and CRCW06033M48FKEA both specify ±100ppm/°C, while RMCF0603FT3M48 specifies ±200ppm/°C. For a 3.48 MOhms resistor across a 210°C temperature range (-55°C to 155°C), the maximum resistance variation is 0.73 MOhms (±100ppm/°C) or 1.46 MOhms (±200ppm/°C). Selection depends on circuit tolerance requirements.

Q: Are the physical dimensions interchangeable?

A: All three parts conform to the 0603 (1608 Metric) package specification. RC1608F3484CS dimensions are 1.60mm x 0.80mm with 0.55mm maximum height. RMCF0603FT3M48 dimensions are 1.55mm x 0.80mm with 0.55mm maximum height. CRCW06033M48FKEA dimensions are 1.55mm x 0.85mm with 0.50mm maximum height. These variations are within standard 0603 package tolerance and do not affect PCB layout compatibility.

Q: Which part should be selected for automotive applications?

A: RMCF0603FT3M48 or CRCW06033M48FKEA are both qualified with AEC-Q200 certification for automotive applications. RC1608F3484CS does not specify automotive qualification and should not be used in automotive designs without additional qualification documentation.

Q: What is Moisture Sensitivity Level 1?

A: MSL 1 (Unlimited) indicates the component has unlimited shelf life without moisture bake-out requirements. All three parts carry MSL 1 classification, confirming no special storage or handling procedures are required.

Q: Are all parts ROHS3 compliant?

A: Yes. RC1608F3484CS, RMCF0603FT3M48, and CRCW06033M48FKEA are all ROHS3 Compliant and REACH Unaffected, confirming compliance with current environmental and hazardous substance regulations.
