Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC0603F3322CS is determined by strict equivalence across the following parameters:

Critical Matching Parameters:

• Resistance value: 33.2 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 0.05W / 1/20W (exact match required)
• Package: 0201 (0603 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• RoHS compliance: ROHS3 Compliant (exact match required)

Allowable Variation Parameters:

• Temperature coefficient: ±100ppm/°C to ±250ppm/°C (lower values acceptable)
• Operating temperature range: -55°C ~ 125°C minimum; extended ranges acceptable
• Packaging format: Tape & Reel (TR) or Cut Tape (CT) formats interchangeable
• Moisture sensitivity level: MSL 1 acceptable

Two substitute parts meet these criteria and are classified as follows:

Direct Manufacturer Substitute: CRCW020133K2FKED (Vishay Dale) - identical electrical specifications with improved temperature coefficient and extended operating range.

Similar Manufacturer Substitute: MCR006YRTF3322 (Rohm Semiconductor) - equivalent electrical specifications with matching temperature coefficient; currently discontinued at DiGi Electronics but available in inventory.

Engineering Selection Recommendations

Primary Substitute Selection: CRCW020133K2FKED (Vishay Dale)

The CRCW020133K2FKED is the preferred direct substitute for the RC0603F3322CS. This part maintains identical electrical specifications across all critical parameters while offering superior performance characteristics. The temperature coefficient of ±100ppm/°C is superior to the original part's ±250ppm/°C, resulting in improved resistance stability across temperature variations. The extended operating temperature range of -55°C ~ 155°C provides additional thermal margin compared to the -55°C ~ 125°C specification of the original part. Both parts carry ROHS3 compliance and MSL 1 ratings. The CRCW020133K2FKED is currently in active production status with significantly higher inventory availability (9387 units), ensuring supply chain continuity.

Secondary Substitute Selection: MCR006YRTF3322 (Rohm Semiconductor)

The MCR006YRTF3322 is classified as a similar manufacturer substitute and provides electrical equivalence to the RC0603F3322CS. All critical parameters match exactly: 33.2 kOhms resistance, ±1% tolerance, 0.05W power rating, 0201 package, and thick film composition. The temperature coefficient and operating temperature range are identical to the original part. However, this part is currently discontinued at DiGi Electronics, limiting its suitability for new designs or long-term production commitments. The MCR006YRTF3322 remains available in inventory (3792 units) and is suitable for applications where existing stock must be consumed or where compatibility with legacy designs is required. The Cut Tape (CT) packaging format differs from the original Tape & Reel (TR) format, requiring adjustment to assembly processes.

Compliance and Regulatory Status

All three parts—RC0603F3322CS, CRCW020133K2FKED, and MCR006YRTF3322—are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component manufacturing and distribution. All parts carry ECCN classification EAR99 and HTSUS code 8533.21.0030, indicating no export restrictions or special handling requirements.

Frequently Asked Questions (FAQ)

Q: Can the CRCW020133K2FKED be used as a direct replacement for the RC0603F3322CS without circuit redesign?

A: Yes. The CRCW020133K2FKED meets all critical electrical specifications: 33.2 kOhms ±1%, 0.05W power rating, 0201 package, and thick film composition. The superior temperature coefficient (±100ppm/°C vs. ±250ppm/°C) and extended operating range (-55°C ~ 155°C vs. -55°C ~ 125°C) provide performance benefits without requiring circuit modifications. PCB footprints are identical.

Q: What is the difference between Tape & Reel (TR) and Cut Tape (CT) packaging?

A: Tape & Reel (TR) packaging supplies components on continuous carrier tape wound on reels, suitable for automated pick-and-place assembly equipment. Cut Tape (CT) packaging supplies components on cut segments of carrier tape, typically used for manual assembly or lower-volume production. Both formats contain identical components; the difference is in handling and assembly process compatibility.

Q: Why is the MCR006YRTF3322 marked as discontinued if inventory is available?

A: Discontinued status indicates that Rohm Semiconductor has ceased production of this part number. Existing inventory from distributors remains available for purchase, but no new production runs will occur. This part is suitable for current projects but not recommended for designs requiring long-term component availability or future production scaling.

Q: Are there any performance differences between the three parts that would affect circuit operation?

A: The primary performance difference is the temperature coefficient. The CRCW020133K2FKED exhibits ±100ppm/°C drift, while both the RC0603F3322CS and MCR006YRTF3322 exhibit ±250ppm/°C drift. In applications where resistance value stability across temperature variations is critical, the CRCW020133K2FKED provides superior performance. For most general-purpose applications, all three parts are functionally equivalent.

Q: Can these parts be used interchangeably in existing production lines?

A: The RC0603F3322CS and CRCW020133K2FKED are fully interchangeable in production lines configured for Tape & Reel (TR) packaging. The MCR006YRTF3322 requires process adjustment due to Cut Tape (CT) packaging format. All three parts are compatible with standard 0201 (0603 Metric) PCB footprints and reflow soldering processes.

Q: What is the significance of MSL 1 (Unlimited) rating?

A: MSL 1 (Moisture Sensitivity Level 1) indicates that the component has unlimited shelf life and requires no special moisture control during storage or handling. These parts do not require dry-pack storage, desiccant bags, or baking procedures prior to assembly, simplifying inventory management and reducing component preparation time.

Q: Are all three parts suitable for RoHS3 compliant applications?

A: Yes. All three parts—RC0603F3322CS, CRCW020133K2FKED, and MCR006YRTF3322—carry ROHS3 compliance certification, meeting all current regulatory requirements for restricted substance elimination in electronic components.
