Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC0603F510CS is determined by strict alignment with the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 51 Ohms
• Tolerance: ±1%
• Power rating: 0.05W (1/20W)
• Package / Case: 0201 (0603 Metric)
• Composition: Thick Film
• RoHS3 Compliance
• MSL 1 (Unlimited)

Allowable Variations:

• Manufacturer identity (different suppliers)
• Packaging format (Cut Tape vs. Tape & Reel)
• Temperature coefficient (within operational envelope)
• Operating temperature range (substitute may exceed minimum requirements)
• Inventory source and availability

The substitute part CRCW020151R0FKED from Vishay Dale meets all mandatory matching parameters and is therefore classified as a direct equivalent for the RC0603F510CS.

Parameter Comparison

Engineering Selection Recommendations

RC0603F510CS (Samsung Electro-Mechanics):

• Primary selection for applications requiring Cut Tape packaging format
• Active product status with established supply chain
• ROHS3 compliant and MSL 1 rated
• Temperature coefficient of ±250ppm/°C suitable for standard industrial applications within -55°C to 125°C range

CRCW020151R0FKED (Vishay Dale):

• Direct electrical and mechanical equivalent with superior temperature coefficient (±100ppm/°C)
• Extended operating temperature range (-55°C to 155°C) provides margin for high-temperature applications
• Tape & Reel packaging format suitable for automated assembly and high-volume production
• Active product status with ROHS3 compliance and MSL 1 rating
• Selection recommended when Tape & Reel format is required or when extended temperature performance is beneficial

Both parts are functionally interchangeable at the PCB level. Selection between them is determined by packaging requirements and thermal performance margins specific to the application.

Frequently Asked Questions (FAQ)

Q: Can CRCW020151R0FKED replace RC0603F510CS in existing designs?

A: Yes. Both parts are electrically and mechanically identical in resistance value (51 Ohms), tolerance (±1%), power rating (0.05W), package (0201), and physical dimensions. PCB footprints are identical. The primary difference is packaging format (Cut Tape vs. Tape & Reel) and the Vishay part offers superior temperature coefficient and extended operating range.

Q: What is the difference between Cut Tape and Tape & Reel packaging?

A: Cut Tape (CT) packaging supplies components on continuous tape that is cut into segments for manual or semi-automated handling. Tape & Reel (TR) packaging supplies components on continuous tape wound on reels, optimized for automated pick-and-place assembly equipment. Both formats contain identical components; packaging format selection depends on assembly process requirements.

Q: Are there any compliance or regulatory differences between these parts?

A: No. Both RC0603F510CS and CRCW020151R0FKED are ROHS3 compliant, REACH unaffected, and classified as MSL 1 (Unlimited moisture sensitivity level). Both carry identical ECCN (EAR99) and HTSUS (8533.21.0030) classifications.

Q: Why does the Vishay part have a lower temperature coefficient?

A: Temperature coefficient (±100ppm/°C for Vishay vs. ±250ppm/°C for Samsung) reflects manufacturing process differences. Lower temperature coefficient indicates better resistance stability across temperature variations. This is a performance advantage of the Vishay part, not a compatibility issue.

Q: Can I use these parts interchangeably in high-temperature applications?

A: The Vishay CRCW020151R0FKED is rated to 155°C, while the Samsung RC0603F510CS is rated to 125°C. For applications approaching or exceeding 125°C, the Vishay part provides additional thermal margin. Both parts maintain their specified tolerance and performance within their respective operating ranges.

Q: What inventory considerations apply to these parts?

A: RC0603F510CS has 9,244 pieces in stock (Cut Tape format). CRCW020151R0FKED has 21,485 pieces in stock (Tape & Reel format). Inventory levels may vary by supplier and time. Verify current availability with your component distributor.
