Engineering Selection Recommendations

Primary Selection: RC0603F2941CS (Samsung Electro-Mechanics)

The RC0603F2941CS remains the preferred selection when available. Active product status ensures long-term supply chain stability and manufacturer support. Current inventory of 803 units supports immediate procurement requirements. ROHS3 compliance and MSL 1 rating confirm suitability for standard manufacturing and storage environments without special handling protocols.

Substitute Selection: MCR006YRTF2941 (Rohm Semiconductor)

The MCR006YRTF2941 is electrically and mechanically equivalent to the RC0603F2941CS and qualifies as a direct substitute. All critical parameters—resistance value, tolerance, power rating, temperature coefficient, operating range, package dimensions, and compliance certifications—are identical. The part maintains ROHS3 compliance and MSL 1 rating, ensuring compatibility with existing assembly processes and environmental requirements.

Consideration: The MCR006YRTF2941 is listed as Discontinued at DiGi Electronics. While 10,628 units are currently in stock, this status indicates reduced long-term availability. Selection of this substitute should account for potential future supply constraints. Packaging format differs (Cut Tape & Digi-Reel® versus Tape & Reel), which may require adjustment to automated pick-and-place equipment settings but does not affect electrical performance or PCB compatibility.

Frequently Asked Questions (FAQ)

Q: Can MCR006YRTF2941 be used as a direct replacement for RC0603F2941CS on existing PCBs?

A: Yes. Both parts are 0201 (0603 Metric) package with identical dimensions (0.024" L x 0.012" W, 0.60mm x 0.30mm) and maximum seated height (0.010", 0.26mm). Electrical specifications are identical: 2.94 kOhms ±1%, 0.05W power rating, ±250ppm/°C temperature coefficient, and -55°C to 125°C operating range. PCB footprints and assembly processes require no modification.

Q: What is the difference between Tape & Reel (TR) and Cut Tape & Digi-Reel® packaging?

A: Both are surface mount packaging formats suitable for automated assembly. Tape & Reel (TR) provides continuous reel format optimized for high-volume pick-and-place operations. Cut Tape & Digi-Reel® offers flexibility for lower-volume or mixed-component assembly. The electrical and mechanical properties of the component are unaffected by packaging format. Equipment compatibility should be verified with your assembly partner.

Q: Are there compliance or regulatory differences between these parts?

A: No. Both RC0603F2941CS and MCR006YRTF2941 are ROHS3 compliant, REACH unaffected, and classified as MSL 1 (Unlimited moisture sensitivity level). Both carry EAR99 ECCN classification and 8533.21.0030 HTSUS code. No additional certifications, testing, or documentation is required for substitution.

Q: Why is MCR006YRTF2941 marked as Discontinued at DiGi Electronics?

A: Discontinued status indicates that the manufacturer or primary distributor has ceased active promotion or restocking of this part number. However, 10,628 units remain in current inventory. Discontinued status does not affect electrical performance or compatibility. Long-term availability should be confirmed with your component supplier before committing to high-volume designs.

Q: What parameters must remain identical for substitution to be valid?

A: Resistance value (2.94 kOhms), tolerance (±1%), power rating (0.05W), package type (0201), composition (thick film), temperature coefficient (±250ppm/°C), operating temperature range (-55°C to 125°C), and compliance certifications (ROHS3, MSL 1, REACH unaffected) must all match exactly. Any deviation in these parameters disqualifies a part from substitution.

Q: Can parts with different temperature coefficients or operating ranges be substituted?

A: No. Temperature coefficient (±250ppm/°C) and operating temperature range (-55°C to 125°C) are critical stability parameters. Substitutes must match these specifications exactly. Deviations will affect circuit performance across temperature variations and may cause circuit malfunction or reliability issues.

Q: Is moisture-resistant composition a requirement for substitution?

A: The RC0603F2941CS specifies moisture-resistant thick film composition. The MCR006YRTF2941 specifies thick film composition without explicit moisture-resistant designation. Both parts carry MSL 1 (Unlimited) rating, indicating equivalent moisture handling capability. Composition differences do not affect substitution eligibility when MSL ratings are identical.
