Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC0402F203CS is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Resistance Value: 20 kOhms
• Tolerance: ±1%
• Power Rating: 0.03W (1/32W)
• Package / Case: 01005 (0402 Metric)
• Composition: Thick Film
• Temperature Coefficient: ±250ppm/°C
• Operating Temperature Range: -55°C to 125°C
• Moisture Sensitivity Level: MSL 1 (Unlimited)
• RoHS Compliance: ROHS3 Compliant

The CRCW010020K0FREL manufactured by Vishay Dale meets all mandatory parameters and is classified as a direct equivalent substitute. Both components share identical electrical specifications, mechanical dimensions, environmental ratings, and regulatory compliance certifications.
