Substitute Part Grouping Explanation

Substitution of the RC0603F4122CS is determined by strict equivalence across the following critical parameters:

Electrical Specifications:

• Resistance value: 41.2 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 0.05W / 1/20W (exact match required)
• Composition: Thick Film (exact match required)

Mechanical Specifications:

• Package type: 0201 (0603 Metric) (exact match required)
• Physical dimensions: 0.024" L x 0.012" W / 0.60mm x 0.30mm (exact match required)
• Height seated maximum: 0.010" / 0.26mm (exact match required)

Environmental & Compliance:

• RoHS3 compliance (required for equivalent substitution)
• Moisture Sensitivity Level 1 (required for equivalent substitution)
• Operating temperature range compatibility (minimum -55°C to 125°C required)

The substitute part CRCW020141K2FKED from Vishay Dale meets all critical electrical and mechanical parameters. Differences in temperature coefficient and maximum operating temperature do not disqualify substitution, as the RC0603F4122CS specifications remain fully satisfied within the substitute's operating envelope.

Parameter Comparison

Engineering Selection Recommendations

Both the RC0603F4122CS and CRCW020141K2FKED are Active products with full RoHS3 compliance and REACH unaffected status. Selection between these parts is based on availability and supply chain requirements rather than technical performance differences.

The CRCW020141K2FKED from Vishay Dale provides equivalent electrical and mechanical performance with the following considerations:

Inventory Availability: The CRCW020141K2FKED maintains higher stock levels (9815 Pcs) compared to the RC0603F4122CS (1111 Pcs), supporting procurement continuity.

Temperature Performance: The CRCW020141K2FKED operates to 155°C maximum, exceeding the RC0603F4122CS specification of 125°C. This provides additional thermal margin in applications approaching upper temperature limits.

Temperature Coefficient: The CRCW020141K2FKED exhibits ±100ppm/°C compared to ±250ppm/°C for the RC0603F4122CS, indicating superior frequency stability and reduced temperature-dependent resistance drift.

Compliance Equivalence: Both parts satisfy identical RoHS3, REACH, and MSL requirements, ensuring regulatory and environmental compliance parity.

Frequently Asked Questions (FAQ)

Q: Can CRCW020141K2FKED replace RC0603F4122CS in existing designs?

A: Yes. The CRCW020141K2FKED is a direct electrical and mechanical equivalent. Identical resistance (41.2 kOhms), tolerance (±1%), power rating (0.05W), package (0201), and physical dimensions ensure pin-for-pin and footprint compatibility without design modification.

Q: Are there differences in moisture sensitivity between these parts?

A: No. Both parts carry MSL 1 (Unlimited) rating, indicating identical moisture sensitivity classification and handling requirements.

Q: What is the significance of the temperature coefficient difference?

A: The CRCW020141K2FKED temperature coefficient of ±100ppm/°C is superior to the RC0603F4122CS at ±250ppm/°C. This means the substitute exhibits less resistance variation across temperature extremes, beneficial for precision analog circuits and frequency-dependent applications.

Q: Do both parts meet the same compliance standards?

A: Yes. Both RC0603F4122CS and CRCW020141K2FKED are ROHS3 compliant, REACH unaffected, and classified under identical ECCN (EAR99) and HTSUS (8533.21.0030) codes.

Q: Is the extended operating temperature range of CRCW020141K2FKED (-55°C to 155°C) a concern?

A: No. The extended range of the CRCW020141K2FKED is a superset of the RC0603F4122CS range (-55°C to 125°C). The substitute operates safely within all temperature conditions specified for the original part.

Q: Can these parts be used interchangeably in automated assembly?

A: Yes. Identical 0201 package specifications, physical dimensions, and termination count (2) ensure compatibility with standard SMD assembly equipment and processes.
