Engineering Selection Recommendations

CF1/4CT52R472J: This substitute provides full electrical and mechanical compatibility with identical resistance, tolerance, power rating, and thermal characteristics. It differs only in the absence of flame-proof and safety features. Selection is appropriate for applications where flame-proof and safety certifications are not required. The part maintains Active product status and ROHS3 compliance. Higher inventory availability (39006 units) supports supply chain continuity.

CFP1/4CT52R472J: This substitute maintains complete parameter equivalence including flame-proof and safety features identical to the main part. It is suitable for direct replacement in applications requiring flame-proof and safety characteristics. The part maintains Active product status and ROHS3 compliance. Inventory availability (5678 units) supports standard procurement requirements.

Selection between substitutes depends on application-specific requirements for flame-proof and safety features. Both alternatives maintain full compliance with RoHS3 and REACH regulations.

Frequently Asked Questions (FAQ)

Q: Can CF1/4CT52R472J replace CF1/4CVTPR472J in all applications?

A: CF1/4CT52R472J is electrically and mechanically equivalent but lacks flame-proof and safety features. Substitution is valid only for applications where these features are not required by design specifications or regulatory standards.

Q: What is the difference between CF1/4CVTPR472J and CFP1/4CT52R472J?

A: Both parts are parametrically identical with matching resistance, tolerance, power rating, temperature coefficient, and operating range. Both include flame-proof and safety features. They differ only in part numbering and packaging designation.

Q: Are all three parts physically interchangeable?

A: Yes. All three parts share identical axial package dimensions (0.091" Dia x 0.240" L / 2.30mm x 6.10mm) and two-terminal configuration, enabling direct physical substitution on printed circuit boards.

Q: Do substitute parts maintain the same compliance certifications?

A: Yes. All three parts are ROHS3 compliant and REACH unaffected, maintaining identical regulatory compliance status.

Q: Which substitute should be selected for safety-critical applications?

A: CFP1/4CT52R472J maintains flame-proof and safety features identical to the main part and is appropriate for safety-critical applications. CF1/4CT52R472J lacks these features and is not suitable for such applications.
