RC0603F1822CS Equivalent & Substitute Parts

Part Overview

The RC0603F1822CS is an 18.2 kOhms ±1% thick film chip resistor manufactured by Samsung Electro-Mechanics. This 0201 (0603 Metric) surface-mount device is rated for 0.05W (1/20W) power dissipation and operates across the temperature range of -55°C to 125°C. The component is classified as Active product status and is RoHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating. Substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when supply chain optimization is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the RC0603F1822CS is determined by strict equivalence across the following critical parameters:

Resistance value must be 18.2 kOhms with ±1% tolerance. Package configuration must be 0201 (0603 Metric) to ensure mechanical and electrical compatibility with printed circuit board layouts. Power rating must be 0.05W (1/20W) minimum. Composition must be thick film. Both RoHS3 compliance and MSL 1 rating are required for regulatory and manufacturing process compatibility. Operating temperature range must support the minimum specification of -55°C to 125°C.

The substitute part CRCW020118K2FKED from Vishay Dale meets all these criteria and is therefore classified as a direct equivalent.

Parameter Comparison

Engineering Selection Recommendations

Both the RC0603F1822CS and CRCW020118K2FKED are Active product status components with full RoHS3 compliance and REACH unaffected status. The Vishay Dale CRCW020118K2FKED substitute offers an extended operating temperature range of -55°C to 155°C compared to the Samsung part's -55°C to 125°C specification, providing additional thermal margin in applications requiring higher temperature operation. The Vishay part also features a lower temperature coefficient of ±100ppm/°C versus the Samsung part's ±250ppm/°C, resulting in improved frequency stability and reduced drift characteristics across temperature variations. Both components are mechanically and electrically interchangeable within the specified parameters and are suitable for direct substitution in 0201 package applications requiring 18.2 kOhms ±1% resistance at 0.05W power rating.

Frequently Asked Questions (FAQ)

Q: Can CRCW020118K2FKED be used as a direct replacement for RC0603F1822CS?

A: Yes. Both components share identical resistance value (18.2 kOhms), tolerance (±1%), power rating (0.05W), package configuration (0201), composition (thick film), and regulatory compliance (RoHS3, REACH unaffected). Mechanical dimensions and termination count are identical.

Q: What are the differences between these two parts?

A: The primary differences are temperature coefficient (Samsung ±250ppm/°C versus Vishay ±100ppm/°C) and maximum operating temperature (Samsung -55°C to 125°C versus Vishay -55°C to 155°C). The Vishay part provides superior temperature stability and extended thermal operating range.

Q: Are there any package compatibility concerns?

A: No. Both parts use the 0201 (0603 Metric) package with identical physical dimensions (0.024" L x 0.012" W, 0.60mm x 0.30mm) and maximum seated height (0.010", 0.26mm). PCB footprints and assembly processes are fully compatible.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both components are RoHS3 compliant, REACH unaffected, classified under ECCN EAR99, and share the same HTSUS code (8533.21.0030). Both have MSL 1 (Unlimited) moisture sensitivity rating.

Q: Which part should be selected for high-temperature applications?

A: The CRCW020118K2FKED from Vishay Dale is suitable for applications requiring operation up to 155°C, whereas the RC0603F1822CS is rated to 125°C maximum. Selection depends on the specific application temperature requirements.

Q: Are there any performance differences in frequency-dependent applications?

A: The lower temperature coefficient of the Vishay part (±100ppm/°C) provides better frequency stability and reduced drift compared to the Samsung part (±250ppm/°C) across temperature variations. Applications sensitive to resistance drift should consider this parameter.
