Key Parameters

Substitute Part Grouping Explanation

Substitution relationships for RC1608J335CS are established based on the following criteria:

Direct Electrical Equivalence: Parts maintaining 3.3 MOhms resistance, ±5% tolerance, 0.1W power rating, and 0603 package format qualify as direct substitutes.

Tolerance Upgrade Substitutes: Parts with improved tolerance (±1% instead of ±5%) while maintaining all other core parameters are classified as upgrades. These provide enhanced precision for applications requiring tighter resistance values.

Feature Enhancement Substitutes: Parts incorporating Automotive AEC-Q200 certification or improved temperature coefficient specifications are classified as upgrades when electrical parameters remain compatible.

Packaging Variant Consideration: Tape & Reel (TR) and Cut Tape (CT) & Digi-Reel® packaging variants are interchangeable for component selection purposes; packaging choice depends on assembly process requirements.

Discontinued Status: Parts marked as discontinued at supplier level remain functionally equivalent but may have limited availability.

Parameter Comparison

Engineering Selection Recommendations

Direct Substitution (Equivalent Performance): RC0603JR-073M3L (YAGEO) and AC0603JR-073M3L (YAGEO) provide direct electrical equivalence to RC1608J335CS. Both maintain identical resistance, tolerance, power rating, and temperature coefficient specifications. RC0603JR-073M3L is available in higher inventory volume (707,319 pcs). AC0603JR-073M3L adds Automotive AEC-Q200 certification without electrical parameter changes, suitable for applications requiring automotive-grade components.

Tolerance Upgrade Substitutes: KTR03EZPF3304 (Rohm Semiconductor) and RMCF0603FT3M30 (Stackpole Electronics Inc) both provide ±1% tolerance improvement over the ±5% specification of RC1608J335CS. Both maintain 0.1W power rating and 0603 package compatibility. KTR03EZPF3304 includes High Voltage designation; RMCF0603FT3M30 includes Automotive AEC-Q200 certification. These upgrades are applicable when circuit design requires enhanced resistance precision.

Automotive-Grade Alternatives: RMCF0603JT3M30 (Stackpole Electronics Inc) maintains ±5% tolerance matching RC1608J335CS while adding Automotive AEC-Q200 certification. This part is suitable for automotive applications requiring equivalent electrical performance with automotive qualification.

Discontinued Component Consideration: MCR03ERTJ335 (Rohm Semiconductor) is marked as discontinued at DiGi Electronics. While electrically compatible with ±5% tolerance and 0.1W rating, limited availability restricts its use for new designs. Temperature coefficient specification is ±200ppm/°C, differing from the ±100ppm/°C of RC1608J335CS.

Compliance Status: All listed parts maintain ROHS3 compliance, Moisture Sensitivity Level 1 (Unlimited), and REACH Unaffected status, ensuring regulatory compatibility with RC1608J335CS.

Frequently Asked Questions (FAQ)

Q: Can RC0603JR-073M3L replace RC1608J335CS directly in production? A: Yes. RC0603JR-073M3L is electrically and mechanically equivalent, maintaining 3.3 MOhms ±5% resistance, 0.1W power rating, and 0603 package format. Packaging differs (Cut Tape & Digi-Reel® versus Tape & Reel), which affects assembly process compatibility but not component function.

Q: What is the difference between ±5% and ±1% tolerance substitutes? A: Tolerance specification defines the maximum deviation from nominal resistance value. ±5% tolerance permits resistance variation of ±165 kOhms from 3.3 MOhms nominal. ±1% tolerance restricts variation to ±33 kOhms. Applications requiring tighter resistance control benefit from ±1% parts (KTR03EZPF3304, RMCF0603FT3M30), while general-purpose circuits function identically with ±5% tolerance.

Q: Are Automotive AEC-Q200 parts suitable for non-automotive applications? A: Yes. Automotive AEC-Q200 certification indicates enhanced reliability testing and qualification standards. Parts meeting this specification (KTR03EZPF3304, RMCF0603JT3M30, RMCF0603FT3M30, AC0603JR-073M3L) function in non-automotive applications without restriction. AEC-Q200 certification provides additional assurance of component quality and reliability.

Q: What does Temperature Coefficient ±100ppm/°C versus ±200ppm/°C mean? A: Temperature coefficient specifies resistance change per degree Celsius within the operating temperature range. ±100ppm/°C indicates smaller resistance drift with temperature variation compared to ±200ppm/°C. RC1608J335CS and most YAGEO parts specify ±100ppm/°C. Stackpole and Rohm MCR series specify ±200ppm/°C. Applications with strict temperature stability requirements benefit from ±100ppm/°C specification.

Q: Is packaging format (Tape & Reel versus Cut Tape) electrically significant? A: No. Packaging format affects supply chain logistics and assembly equipment compatibility, not electrical performance. Tape & Reel (TR) packaging suits high-volume automated assembly. Cut Tape (CT) & Digi-Reel® packaging suits lower-volume or mixed-component assembly. Component selection should verify packaging compatibility with assembly process requirements.

Q: Why is MCR03ERTJ335 listed if it is discontinued? A: MCR03ERTJ335 remains functionally equivalent to RC1608J335CS for applications where existing inventory exists. Discontinued status indicates limited future availability. New designs should prioritize active-status alternatives (RC0603JR-073M3L, KTR03EZPF3304, RMCF series, AC0603JR-073M3L).

Q: Can I use a ±1% tolerance part in a circuit designed for ±5% tolerance? A: Yes. ±1% tolerance parts are more precise than ±5% specification and function identically in circuits designed for ±5% tolerance. No circuit modification is required. This substitution improves circuit performance without design changes.

Q: What does Moisture Sensitivity Level 1 (Unlimited) indicate? A: MSL 1 (Unlimited) indicates the component requires no special moisture protection during storage or handling. Standard warehouse conditions are acceptable. All listed parts maintain MSL 1 classification, ensuring equivalent moisture handling requirements.
