Substitute Part Grouping Explanation

Equivalency and substitution for the VOF-6-24 AC/DC converter are strictly determined by matching the following key electrical and mechanical parameters: output voltage (24V), output current capability (≥250mA), input voltage range (encompassing original range), output power (≥6W), mounting type (through hole), number of outputs (1), and compliance with relevant regulatory approvals and RoHS standard. Packaging style and case dimensions are considered when mechanical compatibility is required.

Engineering Selection Recommendations

The original part, VOF-6-24, is obsolete. Replacement models PSK-10D-24 and VOF-6B-S24 are active and maintain compatibility with the required output voltage, current, power rating, through-hole mounting, and RoHS compliance. Substitute selections must also align with approval agencies as listed for each option to satisfy application-specific regulatory criteria.

Frequently Asked Questions (FAQ)

Q1: What are the most critical parameters when substituting VOF-6-24?
A1: The key parameters are output voltage (24V), maximum output current (≥250mA), input voltage range, mounting type (through hole), and regulatory approvals.

Q2: Are dimensional differences significant when selecting a substitute?
A2: Size and package/case differences impact mechanical fit; verify dimensions and package requirements for physical compatibility within the application assembly.

Q3: Will substitute models support equivalent power requirements?
A3: Both listed substitutes provide at least the original 6W power (PSK-10D-24: 9.8 W, VOF-6B-S24: 6 W).

Q4: Are all substitutes RoHS compliant?
A4: Yes. All compared parts specify RoHS or ROHS3 compliance.

Q5: Are there differences in regulatory approvals between the substitutes?
A5: Substitute models feature different regulatory approvals. Select as required for the target market and end-use compliance.

Q6: Will the change from open frame to enclosed type (PSK-10D-24) affect compatibility?
A6: Enclosure type impacts mounting and physical integration; consider mechanical constraints as provided in the parameter tables.
