Key Parameters

Substitute Part Grouping Explanation

The substitute part selection is determined strictly by matching the following key parameters:

• Isolated module topology
• Single output configuration
• Input voltage range (36V – 76V)
• Output voltage (1.5V)
• Output current capability (must meet or exceed 3.5A)
• Isolation voltage (1.5kV)
• ITE (Commercial) application suitability
• Operating temperature range (-40°C ~ 85°C, with derating)
• Efficiency (82%)
• RoHS3 compliance

All substitute parts listed must meet or improve upon these criteria.

Parameter Comparison

Engineering Selection Recommendations

The SFS10481R5C is obsolete. Selection of substitute parts must prioritize active status and regulatory compliance to ensure supply chain continuity and adherence to standards. The SFLS15481R5B is active and ROHS3 compliant, aligning with current environmental and safety requirements.

Frequently Asked Questions (FAQ)

Q1: What electrical parameters must match for a DC-DC converter substitute?
A1: The substitute must match or exceed the input voltage range, output voltage, output current, isolation voltage, efficiency, and application suitability as indicated in the key parameters.

Q2: Are mounting type and package configuration considered in substitution?
A2: Yes. Mounting type (through hole versus surface mount) and package dimensions may impact mechanical compatibility, so selection should reflect the available footprint and assembly method.

Q3: Can substitute parts offer higher output current or power?
A3: Substitute parts with higher output current or greater wattage are allowed, provided all other key parameters match.

Q4: Is RoHS3 compliance required for substitution?
A4: ROHS3 compliance is a mandatory parameter based on the provided information and must be matched in any substitute part.

Q5: How do product status differences affect part selection?
A5: Only active parts are suitable substitutes for obsolete components to maintain availability for new designs or replacements.

Q6: Are differences in supplier device package or lead count relevant to functional substitution?
A6: Only explicitly listed mechanical and electrical parameters are considered; supplier device package details influence physical integration and must be evaluated within the limits of provided data.
