Key Parameters

Substitute Part Grouping Explanation

Substitution of the PSS6-5-5/S is determined by electrical and mechanical compatibility across the following critical parameters:

Electrical Compatibility Criteria:

• Input voltage range: 4.5V to 9V minimum and maximum
• Output voltage: 5V nominal
• Output current capacity: 1A minimum
• Power rating: 5W minimum
• Operating temperature range: -40°C to 85°C minimum
• Isolation type: Isolated module configuration

Mechanical Compatibility Criteria:

• Mounting type: Surface mount
• Package classification: SMD module format
• Moisture sensitivity level: MSL 1 or equivalent

Regulatory Compliance:

• ECCN classification: EAR99
• HTSUS code: 8504.40.9580

The CC6-0505SR-E qualifies as a direct substitute based on matching all electrical parameters and maintaining surface mount compatibility, despite minor physical dimension variations and package format differences.

Parameter Comparison

Engineering Selection Recommendations

The CC6-0505SR-E is the direct substitute for the obsolete PSS6-5-5/S based on the following engineering criteria:

Electrical Equivalence: All critical electrical parameters match exactly: input voltage range (4.5V to 9V), output voltage (5V), output current (1A), power rating (5W), and operating temperature range (-40°C to 85°C). Both devices are isolated modules with identical functional specifications.

Product Status Advantage: The CC6-0505SR-E is classified as active, ensuring continued availability and manufacturer support. The PSS6-5-5/S is obsolete, making the CC6-0505SR-E the appropriate selection for new designs and ongoing procurement.

Regulatory Compliance: The CC6-0505SR-E provides explicit RoHS compliance and REACH unaffected status, meeting modern regulatory requirements. Both parts share the same ECCN (EAR99) and HTSUS (8504.40.9580) classifications.

Package Compatibility: While the CC6-0505SR-E uses a 7-SMD module package compared to the PSS6-5-5/S 6-SMD module, both are surface mount formats with compatible MSL ratings (1, Unlimited). Physical dimensions are similar with minor variations that do not preclude direct substitution in most applications.

Isolation Specification: The CC6-0505SR-E specifies 500V isolation voltage, providing documented isolation performance for the substitute part.

Frequently Asked Questions (FAQ)

Q: Can the CC6-0505SR-E directly replace the PSS6-5-5/S in existing designs?

A: Yes. The CC6-0505SR-E meets all electrical specifications of the PSS6-5-5/S: identical input voltage range (4.5V to 9V), output voltage (5V), output current (1A), power rating (5W), and operating temperature range (-40°C to 85°C). Both are isolated modules with surface mount configurations. Physical dimensions differ slightly, but the similar footprint accommodates direct substitution in most PCB layouts.

Q: What is the primary reason for substituting the PSS6-5-5/S?

A: The PSS6-5-5/S is classified as obsolete. The CC6-0505SR-E is an active product from the same manufacturer, ensuring continued availability, technical support, and compliance with current regulatory standards.

Q: Are there differences in the package format between these parts?

A: The PSS6-5-5/S uses a 6-SMD module package, while the CC6-0505SR-E uses a 7-SMD module package. Both are surface mount formats with MSL 1 ratings. The physical dimensions are similar (PSS6-5-5/S: 28.4mm x 20.3mm x 8.0mm; CC6-0505SR-E: 22.9mm x 21.1mm x 8.8mm), allowing substitution in most applications with minor PCB layout adjustments if necessary.

Q: Does the CC6-0505SR-E provide isolation voltage specification?

A: Yes. The CC6-0505SR-E specifies 500V isolation voltage. The PSS6-5-5/S does not provide this specification in available documentation.

Q: What regulatory compliance advantages does the CC6-0505SR-E offer?

A: The CC6-0505SR-E is explicitly RoHS compliant and REACH unaffected. Both parts share identical ECCN (EAR99) and HTSUS (8504.40.9580) classifications, maintaining export and trade compliance.

Q: Are the control features identical between these parts?

A: The PSS6-5-5/S features remote on/off and output current protection (OCP). The CC6-0505SR-E specifies enable control with active low logic. Both provide functional control mechanisms suitable for commercial ITE applications, though the specific control implementation differs.

Q: What is the efficiency rating of the CC6-0505SR-E?

A: The CC6-0505SR-E does not specify efficiency in available documentation. The PSS6-5-5/S specifies 84% efficiency. Both devices operate within the same power rating (5W) and thermal range, indicating comparable performance characteristics.

Q: Is the CC6-0505SR-E suitable for the same temperature range applications?

A: Yes. Both the PSS6-5-5/S and CC6-0505SR-E operate across the identical temperature range of -40°C to 85°C, making them suitable for equivalent thermal environments.
