Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC0603F1871CS is determined by strict alignment of the following critical parameters:

Electrical Specifications: Resistance value (1.87 kOhms), tolerance (±1%), and power rating (0.05W) must be identical. Thick film composition is required for this product category.

Mechanical Compatibility: Package designation (0201 / 0603 Metric), physical dimensions (0.024" L x 0.012" W), and maximum seated height (0.010") must match exactly to ensure PCB footprint compatibility and assembly process compatibility.

Compliance & Environmental: RoHS3 compliance and MSL 1 rating are mandatory. Operating temperature range may extend beyond the original specification without affecting substitution validity, provided the minimum range (-55°C) is maintained.

Packaging Format: Tape & Reel (TR) packaging is standard for this category and does not restrict substitution.

Parameter Comparison

Engineering Selection Recommendations

The CRCW02011K87FKED (Vishay Dale) is a direct electrical and mechanical equivalent to the RC0603F1871CS (Samsung Electro-Mechanics). Both components meet identical core specifications for resistance, tolerance, power rating, package dimensions, and compliance requirements.

Selection between these parts is based on availability, supply chain considerations, and design margin requirements. The Vishay Dale substitute offers an extended operating temperature range (-55°C ~ 155°C versus -55°C ~ 125°C) and superior temperature coefficient performance (±100ppm/°C versus ±250ppm/°C), which may provide additional design margin in temperature-sensitive applications. Both components maintain RoHS3 compliance and MSL 1 rating, ensuring equivalent environmental and moisture handling characteristics.

Frequently Asked Questions (FAQ)

Q: Can CRCW02011K87FKED replace RC0603F1871CS in existing designs?

A: Yes. Both components share identical electrical specifications (1.87 kOhms ±1%, 0.05W), mechanical dimensions (0201 package, 0.024" x 0.012"), and compliance certifications (RoHS3, MSL 1). Direct substitution is valid for PCB assembly and circuit operation.

Q: Are there differences in temperature performance between these parts?

A: The Vishay Dale CRCW02011K87FKED operates across -55°C ~ 155°C, extending 30°C above the Samsung RC0603F1871CS range (-55°C ~ 125°C). The Vishay part also exhibits lower temperature coefficient (±100ppm/°C versus ±250ppm/°C), resulting in improved stability across temperature variations.

Q: Do these components have identical moisture sensitivity ratings?

A: Yes. Both the RC0603F1871CS and CRCW02011K87FKED carry MSL 1 (Unlimited) ratings, indicating no moisture sensitivity restrictions for storage, handling, or assembly processes.

Q: Is the 0201 package the same as 0603 Metric?

A: Yes. The designations 0201 and 0603 Metric refer to the same physical package format. Dimensions are 0.024" L x 0.012" W (0.60mm x 0.30mm) with maximum seated height of 0.010" (0.26mm).

Q: What is the significance of the ±1% tolerance specification?

A: The ±1% tolerance indicates that the actual resistance value will fall within 1.8513 kOhms to 1.8887 kOhms. Both substitute parts maintain this tolerance specification, ensuring equivalent circuit performance and precision requirements.

Q: Are both components available in Tape & Reel packaging?

A: Yes. Both the RC0603F1871CS and CRCW02011K87FKED are supplied in Tape & Reel (TR) format, standard for high-volume surface mount assembly operations.
