• Power rating: 0.05W (1/20W)
• Package type: 0201 (0603 Metric)
• Composition: Thick Film
• Physical dimensions: 0.024" L x 0.012" W (0.60mm x 0.30mm)
• Number of terminations: 2
• RoHS3 compliance
• MSL 1 rating

The CRCW02014K02FKED from Vishay Dale meets all critical electrical and mechanical specifications. Both components share identical resistance, tolerance, power rating, package configuration, and dimensional characteristics. Both are RoHS3 compliant with MSL 1 moisture sensitivity ratings, ensuring direct substitution capability in equivalent circuit applications.

Parameter Comparison

Engineering Selection Recommendations

Both the RC0603F4021CS and CRCW02014K02FKED are Active product status components with full RoHS3 compliance and MSL 1 ratings. The components are electrically and mechanically equivalent for standard circuit applications requiring 4.02 kOhms ±1% resistance at 0.05W power dissipation in 0201 package format.

The CRCW02014K02FKED offers an extended operating temperature range (-55°C to 155°C versus -55°C to 125°C) and superior temperature coefficient performance (±100ppm/°C versus ±250ppm/°C). These enhanced specifications provide additional design margin in temperature-sensitive applications, though both components satisfy the baseline operating temperature requirement of -55°C to 125°C.

Selection between these components should be based on application-specific temperature requirements, supply chain availability, and design margin considerations. Both components are suitable for direct substitution in equivalent circuit positions.

Frequently Asked Questions (FAQ)

Q: Can CRCW02014K02FKED replace RC0603F4021CS in any application?

A: Yes. Both components share identical electrical specifications (4.02 kOhms ±1%), power rating (0.05W), package type (0201), and physical dimensions. Both are RoHS3 compliant with MSL 1 ratings. Direct substitution is supported for equivalent circuit applications.

Q: What is the difference in temperature coefficient between these parts?

A: The RC0603F4021CS has a temperature coefficient of ±250ppm/°C, while the CRCW02014K02FKED has ±100ppm/°C. The Vishay Dale component exhibits superior temperature stability. For applications operating within the standard -55°C to 125°C range, both coefficients are acceptable. Applications requiring enhanced temperature stability should prioritize the CRCW02014K02FKED.

Q: Are the physical dimensions identical?

A: Yes. Both components are 0.024" L x 0.012" W (0.60mm x 0.30mm) with maximum seated height of 0.010" (0.26mm). PCB layout and assembly processes require no modification for substitution.

Q: Do both parts meet RoHS3 compliance requirements?

A: Yes. Both RC0603F4021CS and CRCW02014K02FKED are RoHS3 compliant with MSL 1 (Unlimited) moisture sensitivity ratings. Both are suitable for applications with RoHS3 compliance mandates.

Q: What is the operating temperature difference?

A: The RC0603F4021CS operates from -55°C to 125°C. The CRCW02014K02FKED operates from -55°C to 155°C. The Vishay Dale component provides 30°C additional upper temperature margin. For applications limited to -55°C to 125°C operation, both components are equivalent.
