Substitute Part Grouping Explanation

Substitution eligibility for the CFS1/4CVTR223J is determined by strict equivalence across the following parameters:

• Resistance value: 22 kOhms (exact match required)
• Tolerance: ±5% (exact match required)
• Power rating: 0.25W/1/4W (exact match required)
• Composition: Carbon Film (exact match required)
• Package: Axial through-hole (exact match required)
• Temperature coefficient: -450/+350 ppm/°C (exact match required)
• Operating temperature range: -55°C to +155°C (exact match required)
• Physical dimensions: 0.067" Dia × 0.126" L (exact match required)
• Compliance: ROHS3 Compliant, REACH Unaffected (exact match required)

The substitute part CFS1/4CT52R223J meets all electrical and mechanical criteria for direct substitution.

Frequently Asked Questions (FAQ)

Q: Can CFS1/4CT52R223J be used as a direct replacement for CFS1/4CVTR223J?

A: Yes. Both parts share identical resistance (22 kOhms), tolerance (±5%), power rating (0.25W), composition (carbon film), package type (axial), temperature coefficient (-450/+350 ppm/°C), operating temperature range (-55°C to +155°C), and physical dimensions (0.067" Dia × 0.126" L). Compliance certifications are equivalent.

Q: Are there differences in the flame-proof or safety features between these parts?

A: The main part CFS1/4CVTR223J lists flame-proof and safety features in its description. The substitute part CFS1/4CT52R223J does not explicitly list these features in the provided data. Verify specific safety requirements with the manufacturer if flame-proof certification is critical for your application.

Q: What is the significance of the different part number suffixes (CVTR vs. CT52R)?

A: The suffix variation reflects different manufacturing batches or packaging configurations within the same electrical and mechanical specification family. Both parts conform to the CF series standard from KOA Speer Electronics, Inc.

Q: Can these axial resistors be used in automated assembly processes?

A: Yes. Both parts are supplied in Cut Tape (CT) packaging format, which is compatible with standard tape-and-reel automated insertion equipment for through-hole component placement.

Q: What compliance certifications apply to both parts?

A: Both CFS1/4CVTR223J and CFS1/4CT52R223J are ROHS3 Compliant and REACH Unaffected. Both carry ECCN classification EAR99 and HTSUS code 8533.10.0065.
