Key Parameters

Substitute Part Grouping Explanation

Substitution is conducted strictly according to the following parameters, as explicitly provided: manufacturer, output voltage and current, input voltage range, isolation voltage, temperature range, efficiency, mounting type, number of outputs, and compliance certifications. Only models meeting or exceeding these values for the relevant fields are deemed substitutable within the isolated module DC-DC converter category.

Key parameters for substitution:

• Manufacturer (Cosel USA, Inc.)
• Type (Isolated Module)
• Input Voltage Range (36V - 76V)
• Output Voltage (2V)
• Output Current (≥3A)
• Isolation Voltage (1.5 kV)
• Operating Temperature (-40°C ~ 85°C with derating)
• Efficiency (85%)
• Mounting Type (Surface Mount)
• Compliance (ROHS3, MSL 2, EAR99, HTSUS 8504.40.9580)

Parameter Comparison

Engineering Selection Recommendations

The primary part, SFS104802B, is categorized as obsolete. Substitute selection is supported by matching or exceeding input voltage range, output voltage, output current, isolation rating, operating temperature, efficiency, mounting type, and verified compliance (ROHS3, MSL 2, EAR99, HTSUS classification). SFLS154802B is listed as active and holds equivalent compliance and certifications.
