Equivalent & Substitute Parts Reference for PSS6-5-3R3

Part Overview

The PSS6-5-3R3 (TDK-Lambda Americas Inc) is an isolated module DC-DC converter providing a single 3.3V output at up to 1.2A, designed for ITE (Commercial) applications. With input voltage range of 4.5V to 9V and 4W output power, this converter features remote on/off and over-current protection (OCP), supporting through-hole mounting in a 6-DIP module package. The product is obsolete, and identifying alternative compatible models is required for ongoing designs, service support, and procurement needs.

Key Parameters

Substitute Part Grouping Explanation

Substitution is based solely on matching critical electrical and mechanical parameters: input voltage range, output voltage, maximum output current, module type, number of outputs, application category, mounting method, and operational temperature range. Only those components that meet these requirements and provide equivalent or better performance are considered appropriate substitutes.

Key parameters for substitution:

• Number of Outputs
• Type (Isolated Module)
• Voltage - Input (Min)
• Voltage - Input (Max)
• Voltage - Output 1
• Current - Output (Max)
• Applications (ITE / Commercial)
• Operating Temperature Range
• Mounting Type

Parameter Comparison

Engineering Selection Recommendations

The PSS6-5-3R3 DC-DC converter is classified as obsolete. The CC6-0503SF-E is an active replacement from the same manufacturer, aligning with the application category, operational temperature range, electrical parameters, and mounting style. The CC6-0503SF-E is RoHS compliant and REACH unaffected, supporting regulatory requirements. Both parts fall under ECCN EAR99 and HTSUS 8504.40.9580 classifications.

Frequently Asked Questions (FAQ)

Q1: What key parameters must match for an isolated module DC-DC converter substitution?
A1: The substitution must ensure identical input voltage range, output voltage, maximum output current, application category, module type, mounting method, and operational temperature range.

Q2: Is package size a critical factor in selecting a substitute for PSS6-5-3R3?
A2: Package size and footprint must be considered for physical compatibility during board layout and assembly. The substitute (CC6-0503SF-E) has a different package (7-DIP module) and slightly different dimensions.

Q3: How do compliance and certifications impact selection?
A3: RoHS and REACH compliance, along with ECCN and HTSUS classification, may be required for procurement and regulatory adherence. The substitute CC6-0503SF-E meets these compliance standards.

Q4: Can application category affect substitute qualification?
A4: Yes. Both PSS6-5-3R3 and CC6-0503SF-E are suited for ITE (Commercial) applications, which supports direct replacement.

Q5: Are electrical features such as remote on/off and OCP mandatory for substitution?
A5: Only parameters explicitly listed in both main and substitute parts are used for substitution. The CC6-0503SF-E does not list remote on/off or OCP within the provided data.

Q6: Is mounting type interchangeable between these models?
A6: Both models support through-hole mounting, making them compatible in terms of assembly process.
