Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC0603F183CS is determined by the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 18 kOhms
• Tolerance: ±1%
• Power rating: 0.05W (1/20W)
• Package / Case: 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 status
• Moisture Sensitivity Level: 1 (Unlimited)

Allowable Variations:

• Operating temperature range may extend beyond the main part specification
• Temperature coefficient may differ within acceptable limits for the application
• Packaging format (Cut Tape vs. Tape & Reel) does not affect electrical equivalence
• Inventory availability and supplier sourcing do not affect technical substitution

The identified substitute CRCW020118K0FKED from Vishay Dale meets all mandatory matching parameters and is therefore classified as a direct electrical and mechanical equivalent.

Engineering Selection Recommendations

RC0603F183CS (Samsung Electro-Mechanics):

• Primary choice when Samsung sourcing is specified or preferred
• Active product status with established supply chain
• ROHS3 compliant and REACH unaffected
• Moisture Sensitivity Level 1 (Unlimited) suitable for standard storage and handling
• Operating temperature range -55°C to 125°C covers standard industrial applications

CRCW020118K0FKED (Vishay Dale):

• Direct substitute when Samsung part is unavailable
• Active product status with higher inventory availability (50,408 pcs vs. 3,967 pcs)
• ROHS3 compliant and REACH unaffected
• Moisture Sensitivity Level 1 (Unlimited) equivalent to main part
• Extended operating temperature range (-55°C to 155°C) provides additional thermal margin
• Tighter temperature coefficient (±100ppm/°C vs. ±250ppm/°C) offers improved stability
• Tape & Reel packaging suitable for automated assembly processes

Both parts satisfy all regulatory and compliance requirements. Selection between them is based on availability, packaging format requirements, and thermal performance specifications of the application.

Frequently Asked Questions (FAQ)

Q: Can CRCW020118K0FKED be used as a direct replacement for RC0603F183CS?

A: Yes. Both parts are 18 kOhms ±1% thick film chip resistors in 0201 (0603 Metric) packages with identical power ratings (0.05W), physical dimensions, and compliance certifications. Electrical and mechanical compatibility is confirmed.

Q: What are the differences between these two parts?

A: The primary differences are: (1) Operating temperature range—CRCW020118K0FKED extends to 155°C versus 125°C for RC0603F183CS; (2) Temperature coefficient—CRCW020118K0FKED specifies ±100ppm/°C versus ±250ppm/°C for RC0603F183CS; (3) Packaging format—RC0603F183CS is supplied in Cut Tape while CRCW020118K0FKED is supplied in Tape & Reel; (4) Manufacturer—Samsung Electro-Mechanics versus Vishay Dale.

Q: Does packaging format (Cut Tape vs. Tape & Reel) affect electrical performance?

A: No. Packaging format is a logistics and assembly consideration only. Both Cut Tape and Tape & Reel formats contain electrically identical components. Selection depends on assembly equipment compatibility and handling requirements.

Q: Are both parts RoHS3 compliant?

A: Yes. Both RC0603F183CS and CRCW020118K0FKED are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards.

Q: What does Moisture Sensitivity Level 1 (Unlimited) mean?

A: MSL 1 (Unlimited) indicates the component has no moisture sensitivity restrictions. These parts can be stored and handled under standard conditions without special moisture control measures or time-limited shelf life constraints.

Q: Which part should I select for high-temperature applications?

A: CRCW020118K0FKED is suitable for applications requiring operation up to 155°C. RC0603F183CS is rated to 125°C. Selection depends on the specific thermal requirements of your application.

Q: Are there any other 18 kOhms ±1% 0201 resistors available as substitutes?

A: Based on the provided input parameters, only CRCW020118K0FKED is identified as an equivalent substitute. Other manufacturers may produce similar parts, but only CRCW020118K0FKED is confirmed as meeting all mandatory matching parameters for direct substitution.
