Part Overview

The RC0603J333CS is a 33 kOhms ±5% thick film chip resistor manufactured by Samsung Electro-Mechanics, rated at 0.05W (1/20W) in a 0201 (0603 Metric) surface mount package. This component is classified as Active product status with full RoHS3 compliance and unlimited moisture sensitivity level (MSL 1). The part is supplied in Tape & Reel packaging format.

Equivalent and substitute parts are identified based on matching or exceeding the core electrical specifications: 33 kOhms nominal resistance value, 0.05W power rating, 0201 package form factor, and thick film composition. Substitute parts may vary in tolerance grade, temperature coefficient, and maximum operating temperature while maintaining functional compatibility within the specified parameter envelope.

Substitute Part Grouping Explanation

Substitute parts for the RC0603J333CS are classified into two categories based on electrical parameter alignment:

Upgrade Substitutes: Parts that maintain the 33 kOhms resistance and 0.05W power rating while improving tolerance specification. The CRCW020133K0FKED (Vishay Dale) represents an upgrade path with ±1% tolerance versus the original ±5%, providing superior accuracy. This part maintains identical package form factor (0201), composition (thick film), and RoHS3 compliance. The operating temperature range extends to 155°C (versus 125°C), and temperature coefficient improves to ±100ppm/°C (versus ±250ppm/°C).

Equivalent Substitutes: Parts that match all critical electrical parameters of the original specification. The MCR006YRTJ333 (Rohm Semiconductor) maintains 33 kOhms ±5% resistance, 0.05W power rating, 0201 package, thick film composition, ±250ppm/°C temperature coefficient, and -55°C to 125°C operating range. This part is functionally equivalent with identical MSL 1 rating and RoHS3 compliance. Product status is listed as Discontinued at DiGi Electronics.

All substitute parts share the following critical parameters with the main part:

• Resistance value: 33 kOhms
• Power rating: 0.05W (1/20W)
• Package: 0201 (0603 Metric)
• Composition: Thick Film
• Number of terminations: 2
• RoHS3 compliance
• MSL 1 (Unlimited)
• REACH Unaffected status
• ECCN: EAR99
• HTSUS: 8533.21.0030

Engineering Selection Recommendations

For Active Production and New Designs:

The CRCW020133K0FKED (Vishay Dale) is the recommended upgrade substitute for new designs and active production environments. This part maintains full compatibility with the RC0603J333CS footprint and electrical function while providing superior tolerance specification (±1% versus ±5%). The extended operating temperature range to 155°C and improved temperature coefficient (±100ppm/°C) provide enhanced performance margins. Both parts carry Active product status and full RoHS3 compliance. Tape & Reel packaging is available for both components, supporting automated assembly processes.

For Direct Replacement and Legacy Support:

The MCR006YRTJ333 (Rohm Semiconductor) provides functional equivalence with identical electrical specifications (33 kOhms ±5%, ±250ppm/°C, -55°C to 125°C). This part is suitable for direct replacement applications where tolerance and temperature performance match the original design requirements. However, product status is listed as Discontinued at DiGi Electronics, which may impact long-term availability. Packaging is available in Cut Tape (CT) and Digi-Reel® formats. RoHS3 compliance and MSL 1 rating are maintained.

Compliance and Regulatory Considerations:

All three parts (RC0603J333CS, CRCW020133K0FKED, and MCR006YRTJ333) meet RoHS3 compliance requirements and are REACH Unaffected. All parts carry ECCN classification EAR99 and HTSUS code 8533.21.0030. MSL 1 (Unlimited) rating applies to all parts, eliminating moisture sensitivity constraints during storage and handling.

Frequently Asked Questions (FAQ)

Q: Can the CRCW020133K0FKED replace the RC0603J333CS in existing designs?

A: Yes. The CRCW020133K0FKED maintains identical package form factor (0201), resistance value (33 kOhms), and power rating (0.05W). The ±1% tolerance is tighter than the original ±5%, which is compatible with designs specified for ±5% tolerance. Footprint and electrical function are fully compatible.

Q: What is the difference between the RC0603J333CS and MCR006YRTJ333?

A: Both parts are functionally equivalent with matching 33 kOhms ±5% resistance, 0.05W power rating, 0201 package, and operating temperature range (-55°C to 125°C). The primary difference is manufacturer (Samsung versus Rohm) and product status (Active versus Discontinued at DiGi Electronics). Electrical performance and package dimensions are identical.

Q: Why does the CRCW020133K0FKED have a higher operating temperature limit?

A: The CRCW020133K0FKED is rated to 155°C maximum operating temperature, compared to 125°C for the RC0603J333CS. This reflects the design specifications of the Vishay Dale CRCW series. Applications limited to 125°C operation will function within specification with either part.

Q: Are all three parts RoHS3 compliant?

A: Yes. The RC0603J333CS, CRCW020133K0FKED, and MCR006YRTJ333 all carry RoHS3 Compliant status. All parts are REACH Unaffected and carry ECCN classification EAR99.

Q: What does MSL 1 (Unlimited) mean for these resistors?

A: MSL 1 (Unlimited) indicates that these parts have no moisture sensitivity constraints. They do not require special dry-pack storage or baking procedures prior to soldering. Standard storage conditions are acceptable for all three parts.

Q: Can I use these parts interchangeably in automated assembly?

A: The RC0603J333CS and CRCW020133K0FKED are both supplied in Tape & Reel (TR) format, supporting standard automated pick-and-place assembly. The MCR006YRTJ333 is supplied in Cut Tape (CT) and Digi-Reel® format, which may require different feeder configurations. Verify packaging compatibility with your assembly equipment before substitution.

Q: What is the tolerance difference between ±5% and ±1%?

A: For a 33 kOhms resistor, ±5% tolerance allows values between 31.35 kOhms and 34.65 kOhms. The ±1% tolerance of the CRCW020133K0FKED restricts values to 32.67 kOhms and 33.33 kOhms. The tighter tolerance provides superior accuracy for precision circuit applications.

Q: Is the MCR006YRTJ333 still available for purchase?

A: The MCR006YRTJ333 is listed as Discontinued at DiGi Electronics. Availability through other distributors should be verified before design selection. For new designs, the CRCW020133K0FKED (Active status) or RC0603J333CS (Active status) are recommended for assured long-term supply.
