RC0603F182CS Equivalent & Substitute Parts

Part Overview

The RC0603F182CS is a 1.8 kOhms ±1% thick film chip resistor manufactured by Samsung Electro-Mechanics in the 0201 (0603 Metric) package format. This 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 with ROHS3 compliance and unlimited moisture sensitivity level (MSL 1). Equivalent and substitute parts are necessary when the primary part experiences supply constraints, inventory limitations, or when design flexibility across multiple qualified suppliers is required for production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC0603F182CS is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 1.8 kOhms
• Tolerance: ±1%
• Power rating: 0.05W (1/20W)
• Package format: 0201 (0603 Metric)
• Composition: Thick Film
• Number of terminations: 2
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity level: 1 (Unlimited)

Allowable Variation Parameters:

• Temperature coefficient: Substitutes may vary (±100ppm/°C to ±250ppm/°C)
• Operating temperature range: Substitutes may extend the upper limit beyond 125°C
• Packaging format: Tape & Reel (TR) or Cut Tape (CT) & Digi-Reel® formats are interchangeable in manufacturing environments
• Product status: Active or Discontinued at distributor level

The RC0603F182CS qualifies two substitute parts: CRCW02011K80FKED (Vishay Dale) as a direct equivalent with extended temperature range, and MCR006YRTF1801 (Rohm Semiconductor) as a similar substitute with matching temperature coefficient but discontinued status.

Engineering Selection Recommendations

CRCW02011K80FKED (Vishay Dale) - Primary Substitute

The CRCW02011K80FKED is the preferred direct substitute for the RC0603F182CS. This part maintains all mandatory electrical and mechanical parameters while offering an improved temperature coefficient of ±100ppm/°C compared to the Samsung part's ±250ppm/°C. The extended operating temperature range to 155°C provides additional thermal margin for applications requiring higher temperature performance. The part is Active status with full ROHS3 compliance and unlimited MSL rating. Inventory availability is substantial at 28,791 pieces. Packaging is available in Tape & Reel format suitable for automated assembly processes.

MCR006YRTF1801 (Rohm Semiconductor) - Secondary Substitute

The MCR006YRTF1801 qualifies as a similar substitute with identical electrical specifications and matching temperature coefficient of ±250ppm/°C. Physical dimensions and package format are identical to the main part. However, this component is listed as Discontinued at DiGi Electronics, limiting its viability for new production designs or long-term supply assurance. Current inventory is 1,200 pieces. This part is suitable only for applications where existing stock is available and supply continuity is not a primary concern. Packaging is provided in Cut Tape (CT) & Digi-Reel® format.

Selection Criteria:

For applications requiring active product status and assured long-term supply, select CRCW02011K80FKED. For applications where the Samsung RC0603F182CS is currently in production and substitution is driven by temporary supply constraints, either CRCW02011K80FKED or MCR006YRTF1801 may be used interchangeably based on immediate inventory availability, provided that the discontinued status of the Rohm part does not conflict with design lifecycle requirements.

Frequently Asked Questions (FAQ)

Q: Can CRCW02011K80FKED be used as a direct replacement for RC0603F182CS in existing designs?

A: Yes. The CRCW02011K80FKED meets all mandatory electrical and mechanical parameters: 1.8 kOhms ±1%, 0.05W power rating, 0201 package, thick film composition, and ROHS3 compliance. The improved temperature coefficient (±100ppm/°C vs. ±250ppm/°C) and extended temperature range (-55°C to 155°C vs. -55°C to 125°C) provide enhanced performance characteristics without requiring design modification.

Q: What is the difference between the temperature coefficients of these parts?

A: Temperature coefficient defines the resistance change per degree Celsius. The RC0603F182CS and MCR006YRTF1801 both have ±250ppm/°C, meaning resistance can vary by up to 250 parts per million per degree of temperature change. The CRCW02011K80FKED has ±100ppm/°C, indicating tighter resistance stability across temperature variations. For precision analog circuits, the lower temperature coefficient of the Vishay part provides superior performance.

Q: Are there packaging differences between these substitutes?

A: The RC0603F182CS and CRCW02011K80FKED are supplied in Tape & Reel (TR) format. The MCR006YRTF1801 is supplied in Cut Tape (CT) & Digi-Reel® format. Both formats are compatible with standard pick-and-place assembly equipment. Tape & Reel format is preferred for high-volume production due to continuous reel feeding capability.

Q: Why is MCR006YRTF1801 listed as discontinued?

A: The MCR006YRTF1801 is discontinued at DiGi Electronics, the primary distributor. This status indicates that the part is no longer actively manufactured or distributed through standard channels. Existing inventory may be available from secondary sources, but long-term supply assurance cannot be guaranteed. This part should not be selected for new product designs requiring multi-year production support.

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

A: Yes, all three parts share identical 0201 package dimensions (0.024" L x 0.012" W, 0.60mm x 0.30mm) and 0.010" maximum seated height. They are compatible with standard SMD pick-and-place equipment and reflow soldering processes. Tape & Reel and Cut Tape formats both feed through standard component feeders without modification.

Q: What compliance certifications apply to all substitute parts?

A: All three parts are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with HTSUS code 8533.21.0030. All parts have Moisture Sensitivity Level 1 (Unlimited), requiring no special moisture control during storage or handling.
