Engineering Selection Recommendations

Both SPU03L-15 and MEV3S0515SC are listed as Active products and ROHS3 Compliant. The SPU03L-15 is REACH Unaffected, while the MEV3S0515SC is REACH Affected. Selection depends on the required REACH status for the application environment and workflow. No additional compliance or certification fields are provided.

Frequently Asked Questions (FAQ)

Q1: What parameters must match for a DC DC converter module to be considered a valid substitute?
A1: The isolated module type, number of outputs, input voltage range, output voltage, maximum output current, power rating, isolation voltage, application class, mounting type, package, physical dimensions, and RoHS compliance must match based on the provided data.

Q2: Can the MEV3S0515SC be used directly in place of the SPU03L-15?
A2: The MEV3S0515SC matches all key electrical, mechanical, and mounting parameters provided for the SPU03L-15.

Q3: Are there any differences in regulatory compliance between the main part and the substitute?
A3: The SPU03L-15 is REACH Unaffected, whereas the MEV3S0515SC is REACH Affected. RoHS status is the same for both.

Q4: Do the package and mounting type match for both parts?
A4: Both parts use a 7-SIP Module package with 4 leads and are designed for through-hole mounting.

Q5: Are there differences in operating temperature range or efficiency?
A5: SPU03L-15 has an operating temperature of -40°C ~ 90°C (with derating), and MEV3S0515SC has -40°C ~ 85°C. Efficiency values are 86% for SPU03L-15 and 87.5% for MEV3S0515SC, respectively.
