PSS3-24-5 Equivalent & Substitute Parts

Part Overview

The PSS3-24-5 is an isolated module DC-DC converter manufactured by TDK-Lambda Americas Inc, designed to convert input voltages between 18V and 36V to a regulated 5V output at 600mA maximum current. This 3W converter is rated for commercial ITE applications and features remote on/off control with output current protection.

The PSS3-24-5 is classified as obsolete. Identification of equivalent substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production requirements for systems utilizing this converter topology.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the PSS3-24-5 is based on electrical and mechanical compatibility across the following critical parameters:

Electrical Compatibility Criteria:

• Input voltage range: 18V to 36V minimum and maximum
• Output voltage: 5V regulated output
• Output current capacity: 600mA minimum
• Power rating: 3W
• Isolation: Isolated module topology
• Operating temperature: -40°C to 85°C

Mechanical Compatibility Criteria:

• Mounting type: Through hole
• Package category: DIP module format
• Physical dimensions: Compatible with 6-DIP or 7-DIP module footprints

The CC3-2405SF-E satisfies all electrical parameters and operates within the same temperature range. While the package format differs slightly (7-DIP versus 6-DIP), both are through-hole DIP modules with compatible pin configurations for the primary signal functions.

Parameter Comparison

Engineering Selection Recommendations

The CC3-2405SF-E is the direct substitute for the obsolete PSS3-24-5. Both converters are manufactured by TDK-Lambda Americas Inc and provide identical electrical performance across all specified parameters.

Product Status Consideration: The PSS3-24-5 is obsolete, while the CC3-2405SF-E is active production. Selection of the CC3-2405SF-E ensures access to current inventory and ongoing manufacturer support.

Compliance Status: The CC3-2405SF-E carries RoHS Compliant certification and REACH Unaffected status, meeting modern regulatory requirements. The PSS3-24-5 compliance status is not specified in available documentation.

Package Consideration: The CC3-2405SF-E uses a 7-DIP module package compared to the 6-DIP module of the PSS3-24-5. Physical dimensions differ slightly (22.9mm × 16.6mm × 8.5mm versus 25.9mm × 16.0mm × 8.0mm). PCB layout and mechanical mounting must accommodate the 7-DIP footprint.

Control Features: The CC3-2405SF-E includes Enable control with Active Low logic. The PSS3-24-5 features remote on/off capability. Functional equivalence requires verification of control signal integration in the target application.

Frequently Asked Questions (FAQ)

Q: Can the CC3-2405SF-E directly replace the PSS3-24-5 without circuit modification?

A: Electrical substitution is direct. Both converters accept 18V to 36V input and deliver 5V at 600mA output. However, the 7-DIP package footprint differs from the 6-DIP package. PCB layout modification is required to accommodate the different pin configuration and physical dimensions.

Q: What is the difference between the 6-DIP and 7-DIP package formats?

A: Both are through-hole DIP modules with similar signal pin functions. The 7-DIP format includes an additional pin for enhanced control functionality. Pin-to-pin mapping must be verified against the respective datasheets before PCB redesign.

Q: Are the input and output voltage specifications identical between these converters?

A: Yes. Both converters operate with 18V to 36V input range and deliver regulated 5V output at 600mA maximum current. Operating temperature range is identical at -40°C to 85°C.

Q: What is the significance of the RoHS Compliant status on the CC3-2405SF-E?

A: RoHS Compliance indicates the CC3-2405SF-E meets Restriction of Hazardous Substances regulations, restricting lead and other hazardous materials. This is required for many commercial and industrial applications. The PSS3-24-5 RoHS status is not documented.

Q: Is the CC3-2405SF-E available in higher inventory quantities?

A: Yes. The CC3-2405SF-E has 1900 pieces in current stock, compared to 964 pieces of the obsolete PSS3-24-5. The active production status of the CC3-2405SF-E ensures continued availability.

Q: How do the control features differ between these two converters?

A: The PSS3-24-5 provides remote on/off control with output current protection. The CC3-2405SF-E provides Enable control with Active Low logic. Application-specific control requirements must be evaluated against these feature sets.
