Substitute Part Grouping Explanation

Substitute DC-DC converter modules are grouped based on strict matching of parameter sets: input voltage range, total output power, output voltage, mounting type, package/case, application category, module type, and RoHS compliance. Only those parts sharing these core electrical and mechanical parameters are considered substitutable. Approval agency and product status further restrict the groupings.

Engineering Selection Recommendations

Both THL 15-4815WI and URA4824YMD-15WR3 have active product status and meet RoHS compliance requirements. They are compliant with respective approval agencies (CB or CE). Engineers should confirm that approval agency requirements align with application needs. Selection can be based on product status, compliance certification, and mechanical compatibility as specified.

Frequently Asked Questions (FAQ)

Q: What are the main criteria for substituting DC-DC converter modules in this category?
A: Electrical input range, output power, output voltage, mechanical package, mounting style, application category, and compliance certifications.

Q: Can modules with differing approval agencies (CB vs CE) be substituted?
A: Approval agency should match the compliance needs of the end product or region. Verify agency certification as required by application standards.

Q: How important is matching physical dimensions and package type?
A: Physical dimensions and package/case must match for direct PCB placement and mechanical compatibility. Differences may affect fit and integration.

Q: Are the output current ratings interchangeable for these modules?
A: For substitution, ensure the required output voltage and output current do not exceed the substitute module’s ratings as specified.

Q: Does RoHS compliance affect substitution capability?
A: RoHS status should be matched for environmental and regulatory conformity in manufacturing.

Q: What mounting types are allowed for direct substitution?
A: Only modules with identical mounting types (through hole) and package formats (6-DIP Module) are considered suitable substitutes in this context.
