Key Parameters

Substitute Part Grouping Explanation

Substitute DC-DC converter modules are grouped by matching the following key parameters: type (isolated module), output voltage (15V), output current (1A), power rating (15W), voltage isolation rating (1.5 kV), ITE commercial application suitability, protection and control features, and compliance statuses. Mechanical attributes such as mounting type and package/case size are also considered. Substitution is permitted when these parameters align with the original part SFS152415C.

Parameter Comparison

Engineering Selection Recommendations

The SFS152415C is obsolete while the PDQ15-Q24-S15-D remains active and RoHS compliant. Both have the same output voltage, current, power, isolation rating, mounting type, and application suitability, fulfilling substitute requirements. PDQ15-Q24-S15-D meets ECCN and HTSUS designations. All compliance parameters match, allowing substitution based on catalog status and regulatory compatibility.

Frequently Asked Questions (FAQ)

Q: What key parameters must match for a substitute part in DC-DC converter isolated modules?
A: Substitution requires alignment of output voltage, maximum output current, output power, isolation rating, input voltage range, mounting type, package/case, application suitability, protection/control features, and compliance statuses.

Q: Is package size always critical in DC-DC converter substitution?
A: Package size and type should align with board layout and mechanical constraints. Both parts offer through-hole mounting but differ in module dimensions and pin count.

Q: Are regulatory certifications standardized between substitute models?
A: Both SFS152415C and PDQ15-Q24-S15-D carry RoHS status and have the same ECCN and HTSUS codes, conforming to standard regulatory requirements.

Q: How do application and features affect substitution in this category?
A: Application category (ITE Commercial), control features (remote on/off, protection), and isolation voltage must all match for direct substitution without functional loss.

Q: Can substitute parts have different operating temperature ranges?
A: Substitution is permitted when the required operating temperature is met or exceeded. PDQ15-Q24-S15-D supports a wider temperature range than SFS152415C.
