PSS3-5-5/S Equivalent & Substitute Parts Reference

Part Overview

The TDK-Lambda Americas Inc PSS3-5-5/S is an isolated DC-DC converter module providing a single 5V output at up to 600mA from a 4.5V to 9V input, rated at 3W power. It features remote on/off and over-current protection (OCP) and is designed for ITE (commercial) applications. With an operating temperature of -40°C to 85°C (with derating) in a surface-mount 6-SMD module package, this product is classified as Obsolete, necessitating the identification of equivalent or substitute modules for ongoing designs or maintenance requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution candidates are selected strictly based on matching core electrical and mechanical parameters: number of outputs, input voltage range, output voltage, maximum output current, power rating, mounting type, and operating temperature range. Only parts that meet or are equivalent in these fields are grouped as substitutes.

Key parameters considered:

• Number of Outputs
• Voltage - Input (Min)
• Voltage - Input (Max)
• Voltage - Output 1
• Current - Output (Max)
• Power (Watts)
• Mounting Type
• Package / Case
• Operating Temperature

Parameter Comparison

Engineering Selection Recommendations

The PSS3-5-5/S is Obsolete. The substitute CC3-0505SR-E is Active and fully RoHS compliant, with an equivalent electrical specification and surface mount compatibility. Both modules provide the same number of outputs, input and output voltages, current, and operating temperature range. Moisture Sensitivity Level (MSL) and other compliance statutes (ECCN: EAR99, RoHS, REACH) for CC3-0505SR-E are verified in the provided parameters.

Frequently Asked Questions (FAQ)

Q1: What are the most important parameters when substituting a DC-DC converter in this category?
A1: Core substitution criteria include identical number of outputs, equivalent input voltage range, matching output voltage and current, power rating, mounting method, and operating temperature range.

Q2: Is the package difference between 6-SMD and 7-SMD modules significant?
A2: The substitute part uses a 7-SMD module instead of 6-SMD. Ensure that the PCB footprint and physical dimensions are compatible with the host system.

Q3: Do the features or compliance certifications affect interchangeability?
A3: Substitute component CC3-0505SR-E is RoHS compliant, REACH unaffected, and holds the same ECCN and MSL levels as PSS3-5-5/S, satisfying typical engineering compliance requirements.

Q4: Can the CC3-0505SR-E be used in place of the obsolete PSS3-5-5/S for ongoing production or repairs?
A4: Based on supplied parameters, CC3-0505SR-E meets all key performance and compliance criteria for direct substitution, provided that physical size and mounting footprint are confirmed compatible.
