Key Parameters

Substitute Part Grouping Explanation

Substitution suitability for isolated module DC DC converters is determined strictly by the following key parameters: input voltage range, output voltage and current ratings, number of outputs, power rating, package type and size, operating temperature range, mounting type, and compliance requirements. Only parts matching these attributes should be considered as equivalents.

Parameter Comparison

Engineering Selection Recommendations

Both DCWN03B-12 and REC3-2412DRW/H4/A are classified as active products, ROHS3 compliant, REACH unaffected, and share similar ECCN and HTSUS codes, ensuring compatibility within regulatory requirements. Inventory levels and product status support their consideration for direct substitution in systems requiring isolated 3W dual-output DC DC converters with through-hole mounting and industry-standard package dimensions.

Frequently Asked Questions (FAQ)

Q1: What parameters are used to determine whether REC3-2412DRW/H4/A is a suitable substitute for DCWN03B-12?
Selection is strictly based on matching input voltage range, output voltages, output current, power rating, number of outputs, package/case size, mounting type, regulatory compliance, and operational temperature range.

Q2: Can the difference in isolation voltage (3 kV vs. 4 kV) affect substitution?
Substitution is validated by matching the provided isolation voltage specification; field applications requiring exactly 3 kV or above must reference only the explicit listed values.

Q3: Are the package dimensions and pinout directly compatible?
Both converters are specified as 24-DIP Module, 8 Leads, with nearly identical mechanical size, supporting compatibility in PCB layouts where these form factors are required.

Q4: Does compliance status affect selection for regulated environments?
Both parts are ROHS3 compliant and REACH unaffected. These certifications support their use in regions and applications mandating such environmental standards.

Q5: Is there any difference in mounting or handling requirements?
Both items are through-hole modules with identical Moisture Sensitivity Level (MSL) ratings. Handling and assembly processes remain consistent across these substitute options.
