Provided parameters confirm direct interchangeability under relevant compliance and certification requirements.
Frequently Asked Questions (FAQ)
Q: What parameters must match when selecting a substitute for SCWN03B-15?
A: Electrical specifications including input voltage range (18V-36V), output voltage (15V), output current (200mA), wattage (3W), isolation voltage, mounting type, form factor, and package dimensions must match.
Q: Is REC3-2415SRWZ/H4/A a direct substitute for SCWN03B-15?
A: Yes, REC3-2415SRWZ/H4/A matches all specified parameters, including voltage, current, power rating, isolation, package type, and compliance certifications.
Q: Are there any differences in package or mounting between these parts?
A: Both parts use 24-DIP Module, 8 Leads, and through hole mounting. The length dimension differs by 0.01" (31.8mm vs. 32.0mm), which is within standard tolerances for this category.
Q: Do both models meet RoHS and REACH compliance?
A: Both models are ROHS3 Compliant and REACH Unaffected, meeting environmental and regulatory standards.
Q: What should be considered regarding operating temperature ranges?
A: Verify the application requirements with respect to operating temperature. SCWN03B-15 supports -40°C ~ 90°C (with derating), while REC3-2415SRWZ/H4/A supports -40°C ~ 85°C. Select according to specified limits.
Q: Is the substitute suitable for both ITE (Commercial) and Medical applications?
A: REC3-2415SRWZ/H4/A is specified for ITE (Commercial) and Medical, while SCWN03B-15 is specified for ITE (Commercial) only. Select according to the application certifications provided.
