PSK-S25B-5 Equivalent & Substitute Parts Reference

Part Overview

The CUI Inc. PSK-S25B-5 is an enclosed AC/DC converter designed for use in household appliances and ITE (commercial) applications. It provides a single 5V output at up to 4A, with a universal input range of 90 to 264 VAC or 120 to 370 VDC. This product is RoHS3 compliant, certified to numerous international safety and EMC standards, and features through-hole mounting in a 4-DIP module package. The PSK-S25B-5 is classified as obsolete, making it necessary to identify alternative models with compatible electrical, mechanical, and compliance characteristics to ensure continuous support for existing designs or new integrations.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts listed for the PSK-S25B-5 are selected strictly based on matching core parameters: output voltage, number of outputs, mounting type, package/case, input voltage range, and regulatory compliance. The substitute must provide comparable or superior performance within the same category (AC/DC converters, 5V output, through hole, enclosed type), and at least match the critical safety, EMC, and RoHS/REACH certifications.

Key substitution parameters:

• Output voltage: 5V
• Number of outputs: 1
• Input voltage range: Broad AC/DC universal input capability
• Mounting type: Through Hole
• Package / Case: 4-DIP Module
• Regulatory certifications: As listed
• RoHS status: ROHS3 compliant

Parameter Comparison

Engineering Selection Recommendations

Selection of PSK-30D-5 as a substitute for the PSK-S25B-5 is supported by the matching output voltage, mounting style, package type, and compliance with RoHS3 and relevant safety/EMC standards. Verify all necessary approval agency and standard requirements as shown. Both models utilize a 4-DIP module through-hole configuration. PSK-30D-5 is active and suitable for replacement in roles requiring a single 5V output enclosed AC/DC converter.

Frequently Asked Questions (FAQ)

Q: What are the most crucial parameters for replacing PSK-S25B-5 with an alternative?
A: The most crucial parameters are output voltage, number of outputs, input voltage range, mounting type, package dimensions, and regulatory compliance.

Q: Is the package/case important for compatibility?
A: Yes, both main and substitute parts utilize the 4-DIP module for through-hole mounting. Package compatibility is essential to avoid PCB layout changes.

Q: Are there differences in power/output ratings between PSK-S25B-5 and PSK-30D-5?
A: Yes, PSK-30D-5 has a higher maximum output current (6A vs 4A) and power rating (30W vs 20W), but both share a single 5V output.

Q: Does RoHS3 status differ between PSK-S25B-5 and substitute options?
A: No, both are ROHS3 Compliant.

Q: What agency approvals or standards should be compared before selecting a substitute?
A: Compare the "Approval Agency" and "Standard Number" entries in the datasheets for exact matches. Only use information provided for each model.
