PSS6-12-12 Equivalent & Substitute Parts

Part Overview

The PSS6-12-12 is an isolated module DC-DC converter manufactured by TDK-Lambda Americas Inc, designed to convert input voltages between 9V and 18V to a fixed 12V output at 500mA maximum current. This 6W converter is classified as obsolete, which necessitates identification of active equivalent parts for continued system support and new designs. The PSS6-12-12 features remote on/off control and over-current protection, making it suitable for commercial ITE applications requiring isolated power conversion in a compact through-hole package.

Key Parameters

Substitute Part Grouping Explanation

The CC6-1212SF-E qualifies as a direct substitute for the PSS6-12-12 based on the following critical parameters:

Matching Electrical Specifications:

• Input voltage range: 9V to 18V (identical)
• Output current capacity: 500mA (identical)
• Power rating: 6W (identical)
• Single isolated output configuration (identical)
• Operating temperature range: -40°C to 85°C (identical)
• Through-hole mounting technology (identical)

Output Voltage Compatibility: The CC6-1212SF-E provides a 12V to 15V adjustable output range, which encompasses the fixed 12V output of the PSS6-12-12. Applications requiring the fixed 12V output of the original part can operate the CC6-1212SF-E at its 12V setting.

Product Status Advantage: The CC6-1212SF-E is classified as active, ensuring ongoing availability and manufacturing support, whereas the PSS6-12-12 is obsolete.

Parameter Comparison

Engineering Selection Recommendations

The CC6-1212SF-E is the appropriate substitute for the obsolete PSS6-12-12 in applications requiring equivalent electrical performance and reliability. Selection of the CC6-1212SF-E is supported by the following factors:

Electrical Equivalence: All critical electrical parameters match or exceed the original specification. The adjustable output voltage range of the CC6-1212SF-E accommodates the fixed 12V requirement of the PSS6-12-12 without performance degradation.

Product Status: The CC6-1212SF-E maintains active manufacturing status with TDK-Lambda Americas Inc, ensuring long-term availability and supply chain continuity. The PSS6-12-12 obsolete status creates supply risk for new production and field replacements.

Regulatory Compliance: The CC6-1212SF-E carries RoHS Compliant certification and REACH Unaffected status, meeting current environmental and regulatory requirements. Both parts share identical ECCN (EAR99) and HTSUS (8504.40.9580) classifications.

Package Consideration: The CC6-1212SF-E uses a 7-DIP Module package compared to the 6-DIP Module of the PSS6-12-12. Physical dimensions differ slightly (0.90" L x 0.83" W x 0.34" H versus 1.12" L x 0.80" W x 0.31" H). PCB layout and mechanical mounting must be evaluated for the specific application.

Frequently Asked Questions (FAQ)

Q: Can the CC6-1212SF-E directly replace the PSS6-12-12 without circuit modifications?

A: The CC6-1212SF-E provides electrical compatibility with identical input/output current and power specifications. However, the package change from 6-DIP to 7-DIP requires PCB layout verification. The adjustable output voltage feature of the CC6-1212SF-E must be configured to 12V output to match the original fixed output specification.

Q: What is the significance of the adjustable output voltage range on the CC6-1212SF-E?

A: The CC6-1212SF-E output voltage range of 12V to 15V encompasses the fixed 12V output of the PSS6-12-12. Applications can set the output to 12V through the enable and active-low control features, providing functional equivalence to the original part.

Q: Are there physical mounting differences between these parts?

A: Yes. The PSS6-12-12 measures 1.12" L x 0.80" W x 0.31" H, while the CC6-1212SF-E measures 0.90" L x 0.83" W x 0.34" H. The package pin count differs (6-DIP versus 7-DIP). PCB footprint and mounting hole spacing must be verified before substitution.

Q: What control features differ between the PSS6-12-12 and CC6-1212SF-E?

A: The PSS6-12-12 provides remote on/off control with over-current protection. The CC6-1212SF-E provides enable control with active-low logic. Both parts support isolated operation; the CC6-1212SF-E specifies 500V isolation voltage.

Q: Is the CC6-1212SF-E suitable for the same temperature operating range?

A: Yes. Both parts operate across the identical temperature range of -40°C to 85°C with derating applied as necessary for the specific application environment.

Q: What is the moisture sensitivity level of the CC6-1212SF-E?

A: The CC6-1212SF-E is classified as Not Applicable for moisture sensitivity level, indicating it does not require special moisture control during storage or handling, unlike the PSS6-12-12 which carries MSL 1 (Unlimited).
