Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RCS0603F3002CS is determined by strict equivalence across the following parameters:

Primary Electrical Parameters:

• Resistance value: 30 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 0.05W / 1/20W (exact match required)
• Temperature coefficient: ±250ppm/°C (exact match required)
• Operating temperature range: -55°C ~ 125°C (exact match required)

Mechanical Parameters:

• Package / Case: 0201 (0603 Metric) (exact match required)
• Composition: Thick Film (exact match required)

Compliance Parameters:

• RoHS Status: ROHS3 Compliant (minimum requirement)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match required)

Substitute parts must satisfy all electrical, mechanical, and compliance criteria. Packaging format (Cut Tape, Tape & Reel, or Digi-Reel) does not affect electrical or mechanical substitutability but may impact procurement and assembly workflows.

Parameter Comparison

Engineering Selection Recommendations

RC0603F303CS (Samsung Electro-Mechanics)

This substitute is the primary recommended alternative. It maintains identical electrical specifications, mechanical dimensions, and compliance certifications as the RCS0603F3002CS. The component differs only in packaging format (Tape & Reel versus Cut Tape) and product status (Active versus Discontinued). The active product status ensures ongoing availability and supply chain continuity. Both Samsung Electro-Mechanics parts share the same series lineage and manufacturing process, providing highest confidence in functional equivalence.

MCR006YRTF3002 (Rohm Semiconductor)

This substitute meets all electrical and mechanical substitution criteria with identical resistance, tolerance, power rating, temperature coefficient, and operating temperature range. The component is manufactured by Rohm Semiconductor, a different supplier, and carries discontinued status at DiGi Electronics. While electrically and mechanically equivalent, this part should be considered a secondary alternative when RC0603F303CS availability is constrained. Cross-manufacturer substitution requires verification of procurement lead times and supply reliability.

Both substitute parts satisfy ROHS3 compliance, REACH unaffected status, and MSL 1 (Unlimited) moisture sensitivity requirements, ensuring regulatory and environmental compatibility with the original specification.

Frequently Asked Questions (FAQ)

Q: Can RC0603F303CS directly replace RCS0603F3002CS in production?

A: Yes. RC0603F303CS is electrically and mechanically identical to RCS0603F3002CS. Both components share 30 kOhms resistance, ±1% tolerance, 0.05W power rating, ±250ppm/°C temperature coefficient, and 0201 (0603 Metric) package dimensions. The only difference is packaging format (Tape & Reel versus Cut Tape), which does not affect circuit performance or PCB assembly compatibility.

Q: What is the difference between Cut Tape and Tape & Reel packaging?

A: Cut Tape (CT) packaging provides resistors on individual tape segments suitable for manual or small-batch assembly. Tape & Reel (TR) packaging supplies components on continuous reels optimized for automated pick-and-place assembly equipment. Both formats contain identical components; packaging selection depends on assembly process requirements and production volume.

Q: Why is the RCS0603F3002CS discontinued?

A: Product discontinuation at DiGi Electronics reflects supplier lifecycle management and market demand patterns. The RC0603F303CS remains active and provides equivalent functionality, ensuring design continuity without performance impact.

Q: Are there differences in moisture resistance between RCS0603F3002CS and RC0603F303CS?

A: RCS0603F3002CS specifies anti-sulfur and moisture-resistant features, while RC0603F303CS specifies moisture-resistant features. Both components carry MSL 1 (Unlimited) rating, indicating equivalent moisture sensitivity performance. The anti-sulfur specification in RCS0603F3002CS represents an additional feature not required for substitution equivalence.

Q: Can MCR006YRTF3002 be used as a primary substitute?

A: MCR006YRTF3002 meets all electrical and mechanical substitution criteria. However, RC0603F303CS is preferred as the primary substitute due to active product status and Samsung Electro-Mechanics manufacturing continuity. MCR006YRTF3002 serves as a secondary alternative when RC0603F303CS supply is unavailable.

Q: Do all three parts have identical thermal performance?

A: Yes. All three components share ±250ppm/°C temperature coefficient and -55°C ~ 125°C operating temperature range, ensuring identical thermal stability and performance across the specified operating envelope.

Q: What compliance certifications apply to substitute parts?

A: Both RC0603F303CS and MCR006YRTF3002 are ROHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) moisture sensitivity rating. These certifications match the original RCS0603F3002CS specification, ensuring regulatory and environmental compliance.
