Key Parameters

Substitute Part Grouping Explanation

Substitution of the RC0603F49R9CS is determined by strict equivalence across the following critical parameters:

Electrical Specifications: Resistance value (49.9 Ohms), tolerance (±1%), and power rating (0.05W) must be identical. Composition type (thick film) must match.

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

Regulatory & Environmental Compliance: RoHS3 compliance and MSL 1 rating are mandatory. REACH status and ECCN classification must align.

Packaging Format: Tape & Reel (TR) packaging is specified for both main and substitute parts.

The CRCW020149R9FKED from Vishay Dale meets all substitution criteria within these defined parameters.

Parameter Comparison

Engineering Selection Recommendations

Both the RC0603F49R9CS and CRCW020149R9FKED are Active product status components with full RoHS3 compliance and REACH Unaffected designation. Both carry EAR99 ECCN classification and identical HTSUS codes, confirming regulatory alignment.

The CRCW020149R9FKED operates across an extended temperature range (-55°C ~ 155°C) compared to the RC0603F49R9CS (-55°C ~ 125°C). This extended range does not restrict substitution; it provides additional operational margin in applications requiring higher temperature performance.

Both components maintain identical electrical specifications (49.9 Ohms ±1%, 0.05W), mechanical dimensions (0201 package), and environmental ratings (MSL 1). Direct substitution is supported for applications requiring the RC0603F49R9CS specification.

Frequently Asked Questions (FAQ)

Q: Can CRCW020149R9FKED replace RC0603F49R9CS in existing designs?

A: Yes. Both components share identical resistance (49.9 Ohms), tolerance (±1%), power rating (0.05W), package (0201), physical dimensions, and regulatory compliance. PCB footprint and assembly process compatibility are maintained.

Q: What is the significance of the extended operating temperature range in the Vishay part?

A: The CRCW020149R9FKED operates to 155°C versus 125°C for the Samsung part. This extended range provides additional thermal margin but does not affect substitution eligibility. Applications operating within the Samsung specification range (-55°C ~ 125°C) are fully supported by the Vishay component.

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

A: Yes. Both RC0603F49R9CS and CRCW020149R9FKED are supplied in Tape & Reel (TR) format, maintaining consistency with standard SMD assembly processes.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both components are RoHS3 compliant, REACH Unaffected, and classified as EAR99 for export control purposes. HTSUS tariff codes are identical (8533.21.0030).

Q: What is the moisture sensitivity rating for both parts?

A: Both components carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions for storage, handling, or assembly processes.
