Equivalent & Substitute Parts for PSK-S5B-24

Part Overview

The CUI Inc. PSK-S5B-24 is an enclosed AC/DC converter with a single 24V output at 210mA, rated for 5W and supporting a universal input (85–264 VAC, 100–370 VDC). This model is classified as obsolete, which requires identification of alternative or substitute power modules with closely matched electrical and mechanical characteristics for continued design support and inventory fulfillment.

Key Parameters

Substitute Part Grouping Explanation

Substitution is conducted strictly by matching the following explicit product parameters: input voltage range, output voltage, output current rating, total power output, number of outputs, mounting type, package/case, efficiency, operating temperature, regulatory compliance, and mechanical dimensions. Only parts meeting these parameters or providing documented compliance with relevant standards are considered.

The main criteria, based on input data:

• Input Voltage Range
• Output Voltage (24V)
• Output Current (≥208mA)
• Power (5W)
• Enclosed Type, Through Hole Mount
• Relevant Regulatory Compliance and RoHS Status

Parameter Comparison

Engineering Selection Recommendations

The main part, PSK-S5B-24, is obsolete and RoHS compliant, with multiple agency approvals. Substitute parts PSK-5D-24 (CUI Inc.), RAC05-24SK, and RAC05-24SK/277 (Recom Power) maintain strict compliance with RoHS regulations, regulatory approvals (CE, cURus), and similar or extended input voltage ranges. All substitute models are active and available in through-hole, enclosed modules suited for ITE (Commercial) and household appliance applications, as per provided data.

Frequently Asked Questions (FAQ)

Q1: Which electrical parameters must match to ensure substitute compatibility for PSK-S5B-24?
A1: The essential parameters are input voltage range, output voltage (24V), output current rating (≥208mA), power output (5W), number of outputs (1), and electrical efficiency.

Q2: Do the substitute parts provide equivalent mounting and mechanical form factor?
A2: All substitutes specify through-hole mounting and enclosed module types. Differences in package/case and size/dimension should be reviewed for PCB compatibility.

Q3: Are substitute parts compliant with RoHS and similar regulatory standards?
A3: Yes. PSK-5D-24, RAC05-24SK, and RAC05-24SK/277 are all RoHS compliant and have agency certifications aligned with standard requirements.

Q4: What industry approvals must be considered when substituting power converters?
A4: Key approvals include CE, cURus, and CB Scheme, as indicated in the part descriptions. Substitute parts provide these agency certifications per provided data.

Q5: Is there any difference in output regulation among the substitutes?
A5: All models specify line regulation of ±0.5% and load regulation of ±1% (or 1%), supporting equivalent regulation performance within the data set.

Q6: How should package/case differences be addressed?
A6: Substitution should verify that the alternative's package/case and dimensions fit within the original PCB and system design constraints as specified in the data.
