Frequently Asked Questions (FAQ)

Q: What parameters are critical when substituting the PSS3-48-5/S with another part?
A: Substitution requires exact matches for input voltage range, output voltage, maximum output current, power rating, operating temperature, number of outputs, mounting type, and application category.

Q: How do I ensure package compatibility between the PSS3-48-5/S and the substitute CC3-4805SR-E?
A: Both modules are designed for surface mount applications, but confirm the package/case outline and solder pad footprint using the provided size and dimension data.

Q: Is regulatory compliance matched between these parts?
A: Both parts are categorized as ECCN EAR99 and HTSUS 8504.40.9580. The CC3-4805SR-E is RoHS compliant and REACH unaffected as specified.

Q: Are operational temperature ratings equivalent for safe operation?
A: Both parts are rated for -40°C to 85°C operation according to specified criteria.

Q: Can the CC3-4805SR-E be used in all commercial ITE applications previously served by the PSS3-48-5/S?
A: CC3-4805SR-E is specified for ITE (commercial) applications in alignment with the PSS3-48-5/S.

Q: Are there differences in mechanical dimensions or pin count that need consideration?
A: Review the specified size and module configuration. PSS3-48-5/S is in a 6-SMD module (1.02" x 0.63" x 0.31"), while CC3-4805SR-E is in a 7-SMD module (0.90" x 0.65" x 0.35"). Dimensional and pad compatibility should be verified per project constraints.
