Key Parameters

Substitute Part Grouping Explanation

Substitute selection for AC/DC converters relies strictly on matching or exceeding key electrical and mechanical parameters: input voltage range, output voltage, output current, wattage, number of outputs, mounting type, and form factor. Compliance with relevant certifications and RoHS status are also factored when direct replacement is needed for regulated environments. Only parts meeting these criteria are considered valid equivalents or substitutes.

Parameter Comparison

Engineering Selection Recommendations

Selection of the PSK-3D-24 as a substitute is based on the match of output voltage, compatible or broader input voltage range, greater output current, equal or higher power rating, identical mounting type, and compliance with relevant safety and environmental standards. The substitute part is listed as active with ROHS3 compliance and appropriate certifications, meeting the requirements for regulated applications and direct replacement of the obsolete PSK-S2C-24.

Frequently Asked Questions (FAQ)

Q1: What are the critical substitution parameters for AC/DC converters like PSK-S2C-24? A1: The critical parameters are input voltage range, output voltage, output current, power rating, mounting type, and relevant certifications.

Q2: Can PSK-3D-24 be used in place of PSK-S2C-24 without modification? A2: PSK-3D-24 provides the same output voltage and through-hole mounting, with higher output current and power rating. Certifications and RoHS compliance are suited for regulated environments. Package dimensions and pin-out should be checked for mechanical compatibility within the application.

Q3: Are there differences in regulatory approvals between the two models? A3: PSK-S2C-24 is approved under CB Scheme, EN, IEC, UL standards, while PSK-3D-24 holds CE and cURus certifications. Both conform to IEC 62368-1.

Q4: How does the operating temperature range affect substitution eligibility? A4: PSK-3D-24 offers a wider operating temperature range (-40°C ~ 85°C with derating) compared to PSK-S2C-24 (-40°C ~ 70°C with derating), allowing for equal or enhanced performance in temperature-sensitive environments.

Q5: Is the form factor identical between the PSK-S2C-24 and the PSK-3D-24? A5: The form factors differ: PSK-S2C-24 uses a 4-DIP module; PSK-3D-24 uses a 5-DIP module, 4 leads. Size and footprint should be confirmed for mechanical compatibility.
