Substitute Part Grouping Explanation

Substitution of the RC0603F304CS is determined by the following critical parameters:

Electrical Equivalence Requirements:

• Resistance value: 300 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 0.05W / 1/20W (exact match required)
• Composition: Thick Film (exact match required)

Mechanical Equivalence Requirements:

• Package / Case: 0201 (0603 Metric) (exact match required)
• Physical dimensions: 0.024" L x 0.012" W / 0.60mm x 0.30mm (exact match required)
• Height - Seated (Max): 0.010" / 0.26mm (exact match required)
• Number of Terminations: 2 (exact match required)

Environmental & Compliance Requirements:

• Operating temperature range must encompass or equal the specified range
• RoHS3 compliance required
• MSL rating of 1 (Unlimited) required
• REACH Unaffected status required

The substitute part CRCW0201300KFKED (Vishay Dale) meets all electrical, mechanical, and compliance criteria for direct substitution.

Engineering Selection Recommendations

Primary Selection: RC0603F304CS (Samsung Electro-Mechanics)

Use the original RC0603F304CS when Samsung supply chain availability is confirmed and project specifications do not require extended temperature performance beyond 125°C. This component carries Active product status with full RoHS3 compliance and unlimited moisture sensitivity rating.

Substitute Selection: CRCW0201300KFKED (Vishay Dale)

The CRCW0201300KFKED is a direct functional equivalent suitable for applications requiring:

• Extended operating temperature range up to 155°C (versus 125°C maximum for Samsung part)
• Superior temperature coefficient performance (±100ppm/°C versus ±250ppm/°C)
• Equivalent electrical and mechanical specifications across all critical parameters
• Identical RoHS3 compliance and MSL 1 rating

Both parts maintain identical resistance value, tolerance, power rating, package dimensions, and environmental compliance certifications. Selection between these two parts should be based on supply availability, lead time requirements, and whether the extended temperature range of the Vishay part provides operational advantage for the specific application.

Frequently Asked Questions (FAQ)

Q: Can CRCW0201300KFKED be used as a direct replacement for RC0603F304CS?

A: Yes. The CRCW0201300KFKED meets all electrical specifications (300 kOhms ±1%, 0.05W), mechanical dimensions (0201 package, 0.60mm x 0.30mm), and compliance requirements (RoHS3, MSL 1) required for direct substitution. Both components are thick film chip resistors with identical termination count and packaging format.

Q: What are the key differences between these two parts?

A: The primary differences are: (1) Temperature coefficient: Vishay CRCW0201300KFKED operates at ±100ppm/°C versus Samsung RC0603F304CS at ±250ppm/°C; (2) Maximum operating temperature: Vishay extends to 155°C versus Samsung at 125°C. All other electrical and mechanical parameters are identical.

Q: Are the physical dimensions identical?

A: Yes. Both parts use the 0201 (0603 Metric) package with dimensions of 0.024" L x 0.012" W (0.60mm x 0.30mm) and maximum seated height of 0.010" (0.26mm). They are mechanically interchangeable on PCB layouts.

Q: Do both parts have the same RoHS and REACH compliance?

A: Yes. Both RC0603F304CS and CRCW0201300KFKED are ROHS3 Compliant and REACH Unaffected, with identical MSL 1 (Unlimited) moisture sensitivity ratings.

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

A: The CRCW0201300KFKED (Vishay Dale) is suitable for applications operating up to 155°C. The RC0603F304CS (Samsung) is rated to 125°C maximum. Selection depends on the specific operating temperature requirements of the circuit.

Q: Are these parts available in the same packaging format?

A: Yes. Both parts are supplied in Tape & Reel (TR) packaging, enabling compatibility with automated assembly processes.
