Substitute Part Grouping Explanation

Substitution of the RC0603F821CS is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 820 Ohms
• Tolerance: ±1%
• Power rating: 0.05W (1/20W)
• Package / Case: 0201 (0603 Metric)
• Physical dimensions: 0.024" L x 0.012" W (0.60mm x 0.30mm)
• Number of terminations: 2
• Composition: Thick Film
• RoHS compliance: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

The identified substitute part CRCW0201820RFKED (Vishay Dale) meets all mandatory matching parameters. Both parts are Active status products with identical electrical specifications, package geometry, and regulatory compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

Both RC0603F821CS and CRCW0201820RFKED are Active status products with full ROHS3 compliance and REACH unaffected status, making them suitable for regulated applications. The parts are electrically and mechanically equivalent for standard circuit applications requiring 820 Ohms ±1% at 0.05W in the 0201 package.

The CRCW0201820RFKED offers an extended operating temperature range (-55°C ~ 155°C versus -55°C ~ 125°C) and superior temperature coefficient (±100ppm/°C versus ±250ppm/°C). Selection between these parts should be based on application-specific temperature requirements and performance specifications rather than substitution necessity, as both meet the core functional requirements.

Frequently Asked Questions (FAQ)

Q: Can CRCW0201820RFKED be used as a direct replacement for RC0603F821CS?

A: Yes. Both parts share identical resistance (820 Ohms), tolerance (±1%), power rating (0.05W), package geometry (0201/0603 Metric), and physical dimensions (0.024" L x 0.012" W). All regulatory certifications (ROHS3, REACH, ECCN) are equivalent.

Q: What are the differences between these two parts?

A: The primary differences are operating temperature range (CRCW0201820RFKED: -55°C ~ 155°C versus RC0603F821CS: -55°C ~ 125°C) and temperature coefficient (CRCW0201820RFKED: ±100ppm/°C versus RC0603F821CS: ±250ppm/°C). The CRCW0201820RFKED provides superior thermal stability and extended high-temperature operation.

Q: Are the packaging formats compatible?

A: The RC0603F821CS is supplied in Cut Tape (CT) format, while CRCW0201820RFKED is supplied in Tape & Reel (TR) format. Both use the same 0201 (0603 Metric) package. Packaging format differences do not affect component compatibility in circuit applications.

Q: Do both parts meet RoHS and REACH requirements?

A: Yes. Both RC0603F821CS and CRCW0201820RFKED are ROHS3 Compliant and REACH Unaffected, meeting current regulatory standards for electronic components.

Q: Which part should be selected for high-temperature applications?

A: For applications requiring operation above 125°C, the CRCW0201820RFKED is suitable up to 155°C. The RC0603F821CS is limited to 125°C maximum operating temperature.
