Key Parameters

Substitute Part Grouping Explanation

Substitute components are identified strictly based on equivalence in core electrical and mechanical parameters. The essential substitution fields include:

• Manufacturer
• Type (Isolated Module, Isolated PoE Module)
• Number of Outputs
• Voltage - Input (Min/Max)
• Voltage - Output (1)
• Current - Output (Max)
• Power (Watts)
• Voltage Isolation
• Mounting Type
• Package / Case
• RoHS Compliance
• Operating Temperature Range
• Efficiency

The substitute part CBS504812 matches these criteria with variations directly specified in the input.

Parameter Comparison

Engineering Selection Recommendations

The DAS504812 is currently Obsolete, while CBS504812 is Active and meets the required RoHS compliance levels as specified (ROHS3 Compliant). Both parts have Not Applicable Moisture Sensitivity Level and share the essential electrical characteristics—including input voltage, output voltage, and current ratings—mandatory for direct substitution. Product certifications (ECCN EAR99) and HTSUS code are consistent, meeting regulatory and engineering standards as provided.

Frequently Asked Questions (FAQ)

Q1: What are the most critical parameters for substituting DAS504812?
A1: The most critical parameters are input voltage range (36V – 72V or higher), output voltage (12V), output current (4.2A), and power rating (50W). Mounting type, package/case dimensions, and safety compliance (RoHS) must also match the application requirements.

Q2: Is package compatibility between 12-DIP and 13-DIP modules relevant for substitution?
A2: Module package compatibility is determined by provided dimensions and board-level requirements. The substitute CBS504812 uses a 13-DIP module and has similar width and height with shorter length.

Q3: Are there differences in operating temperature and isolation voltage that affect substitution?
A3: The substitute part CBS504812 provides an expanded operating temperature range and higher isolation voltage as listed. Only parameters explicitly mentioned in the part descriptions are compared.

Q4: Does RoHS3 compliance correspond directly to RoHS compliance for engineering selection?
A4: CBS504812 is ROHS3 Compliant while DAS504812 is RoHS Compliant. Both meet current regulatory criteria as stated.

Q5: Can the efficiency and additional features affect the selection process based on provided input?
A5: Efficiency is outlined for both parts, with CBS504812 offering higher efficiency. Feature sets beyond those listed are not considered unless explicitly provided in the parameters.
