Substitute Part Grouping Explanation
Substitute components are selected strictly according to electrical ratings (input voltage range, output voltage, output current, isolation, type, number of outputs), mechanical format (package/case, size/dimensions, mounting type), performance (operating temperature, efficiency), regulatory compliance (RoHS, ECCN), and application. Each substitute listed is a verified match based on these parameters explicitly presented.

Engineering Selection Recommendations
The ISL2403A is marked obsolete and RoHS compliant, requiring a replacement meeting the same regulatory and compliance standards. ATA00F18S-L is active and RoHS compliant per input, with equivalent ECCN and HTSUS. Both parts are suitable for ITE (Commercial) applications. Selection may be made strictly through these compliance and certification criteria provided.
Frequently Asked Questions (FAQ)
Q: What criteria are required for substituting ISL2403A DC DC Converter modules?
A: Selection is determined exclusively by electrical (input range, output voltage/current, isolation), mechanical (package/case, size, mounting), application, compliance (RoHS, ECCN, HTSUS), and operational temperature parameters.
Q: Is the package/case compatible between ISL2403A and ATA00F18S-L?
A: Both utilize 16-SMD modules with nearly identical dimensions; the substitute features 7 leads versus the original’s 6 leads as provided. Compatibility should be evaluated based solely on pinout and package specifications disclosed in this documentation.
Q: Do both parts meet the required RoHS and moisture sensitivity levels for the application?
A: ISL2403A is RoHS3 compliant and rated MSL 1 (unlimited); ATA00F18S-L is RoHS compliant and rated MSL 2 (1 year). Selection must consider these specific compliance levels and storage conditions.
Q: Are both converters suitable for the same temperature range and application type?
A: Both models support -40°C to 85°C operating temperatures and are specified for ITE (Commercial) usage according to the input data.
Q: What differences exist in the feature sets of the main and substitute part?
A: The ISL2403A is specified with SCP (short circuit protection). ATA00F18S-L includes Remote On/Off, OCP (overcurrent protection), and SCP. Only the features listed here may be used for compatibility considerations.
