Parameter Comparison

Engineering Selection Recommendations

Primary Selection (RC0603F4531CS - Samsung Electro-Mechanics): Select this part when Samsung supply chain preference, existing inventory, or design documentation specifies the RC series. Current inventory of 887 pieces supports immediate procurement. Full RoHS3 compliance and MSL 1 rating confirm suitability for standard manufacturing environments.

Substitute Selection (CRCW02014K53FKED - Vishay Dale): Select this part when supply continuity requires alternative sourcing or when higher operating temperature range (-55°C to +155°C versus -55°C to +125°C) provides design margin. The CRCW series demonstrates superior temperature coefficient performance (±100ppm/°C versus ±250ppm/°C), beneficial for precision applications. Significantly higher inventory availability (10,974 pieces) supports large-volume procurement. Full RoHS3 compliance and MSL 1 rating confirm equivalent environmental suitability.

Substitution Validity: Both parts satisfy all mandatory electrical, mechanical, and compliance requirements. Direct substitution is valid without circuit redesign or board layout modification. Physical footprint, electrical performance, and regulatory compliance are identical or superior in the substitute part.

Frequently Asked Questions (FAQ)

Q: Can CRCW02014K53FKED replace RC0603F4531CS in existing designs?

A: Yes. Both parts share identical resistance value (4.53 kOhms), tolerance (±1%), power rating (0.05W), package type (0201), physical dimensions (0.024" x 0.012"), and compliance certifications (RoHS3, MSL 1). No circuit redesign or PCB layout modification is required.

Q: What are the key differences between these two parts?

A: Operating temperature range differs: RC0603F4531CS operates -55°C to +125°C; CRCW02014K53FKED operates -55°C to +155°C. Temperature coefficient differs: RC0603F4531CS is ±250ppm/°C; CRCW02014K53FKED is ±100ppm/°C. These differences favor the Vishay part in high-temperature or precision applications but do not prevent substitution in standard operating conditions.

Q: Are packaging and tape specifications identical?

A: Yes. Both parts are supplied in Tape & Reel (TR) format with identical 0201 (0603 Metric) package designation, dimensions of 0.024" L x 0.012" W (0.60mm x 0.30mm), and maximum seated height of 0.010" (0.26mm). Reel compatibility and pick-and-place machine settings remain unchanged.

Q: Do both parts meet RoHS and environmental compliance requirements?

A: Yes. Both RC0603F4531CS and CRCW02014K53FKED are RoHS3 compliant with MSL 1 (unlimited moisture sensitivity rating). Both are REACH unaffected and classified under ECCN EAR99. Compliance documentation is equivalent for both parts.

Q: Which part should be selected for new designs?

A: Selection depends on supply chain strategy and application requirements. For standard applications within -55°C to +125°C range, either part is acceptable. For applications requiring extended temperature range or superior temperature stability, CRCW02014K53FKED is preferred. For designs with existing Samsung component qualification, RC0603F4531CS maintains consistency.

Q: Is there any performance difference in circuit operation?

A: No functional performance difference exists within the specified operating temperature range of -55°C to +125°C. The superior temperature coefficient of CRCW02014K53FKED (±100ppm/°C) provides better resistance stability across temperature variations, but this difference is negligible in most standard applications. Both parts deliver identical electrical performance at rated specifications.
