Engineering Selection Recommendations

Substitute parts PSK-30D-24 and PSK-S25B-24 are designated as suitable alternatives based on matching core operating parameters, compliance requirements, and certification standards as provided. Both substitutes are active products and meet RoHS compliance. Where certification agencies differ, selection must match system or regulatory requirements as listed.

Frequently Asked Questions (FAQ)

Q1: What determines if PSK-30D-24 or PSK-S25B-24 is a suitable substitute for PSK-S25D-24?
A1: Suitability is based on matching input/output voltage, output current, power rating, package type, mounting type, operating temperature range, regulation performance, and regulatory compliance.

Q2: Are the package/case types for substitutes identical to the PSK-S25D-24?
A2: Substitute parts use 4-DIP Module packages compared to the 9-DIP Module, 6 Leads of PSK-S25D-24. Dimensional and footprint compatibility must be verified within the application based on the parameter table.

Q3: Do substitutes have the same certifications and RoHS compliance status?
A3: All options are RoHS compliant. Certification agencies and standards differ; refer to the detailed approval and standard number fields for system compliance needs.

Q4: How does product status affect substitute selection?
A4: The main part PSK-S25D-24 is obsolete. Only active status parts, PSK-30D-24 and PSK-S25B-24, are appropriate for use as substitutes per inventory and availability.

Q5: Is the output voltage and number of outputs identical?
A5: Yes, all compared models provide a single 24V output as required.
