Key Parameters

Substitute Part Grouping Explanation

Substitution for the VOFM-5-24 is possible when the alternative model matches the following critical parameters: open frame AC/DC converter type, single 24V output, universal input (spanning at least 85 ~ 264 VAC), through hole 4-DIP mounting, and comparable or higher current and power ratings. Additional necessary criteria are medical application suitability, RoHS compliance, relevant international safety approvals, standard numbers, and compatible form factor. Only parts meeting these explicit criteria presented in the input are listed below as substitutes.

Parameter Comparison

Engineering Selection Recommendations

The VOFM-5-24 is obsolete. Both CUI Inc. VMS-20-24 and XP Power EML15US24-P are active models. All listed substitutes offer single 24V output, through hole 4-DIP module mounting, and universal input compliance for medical applications. RoHS and Moisture Sensitivity Level (1, Unlimited) equivalence are maintained. Substitute products hold relevant international certifications and meet medical safety standards as specified.

Frequently Asked Questions (FAQ)

Q1: What are the minimum criteria for substituting VOFM-5-24 in critical medical equipment applications?
All substitutes must be open frame AC/DC converters, provide a single 24V output, accept a universal AC input in the specified range, and have necessary safety and medical approvals.

Q2: Are the listed substitute parts mechanically compatible with VOFM-5-24?
Substitute parts feature through hole mounting and the 4-DIP module case style, ensuring mechanical integration, with minor size variations as outlined.

Q3: How do approval agency and standard number differences affect substitution?
Approvals and standards must be checked against application requirements. Listed substitutes hold specified certifications such as CB Scheme, UL, TUV, and relevant medical safety standards as detailed in the parameter comparison.

Q4: Is RoHS compliance consistent among the substitutes?
All listed substitutes meet or exceed RoHS compliance requirements.

Q5: Can output power or current be higher than the original part when selecting a substitute?
Yes; substitutes provide equal or greater output power and current, given they meet all other mandatory parameters.

Q6: Do operating temperature ranges differ among substitutes?
Substitutes may have equal or wider operating temperature ranges, as listed in the parameter comparison table.

Q7: Are packaging and inventory details considered for electrical equivalency?
Packaging and inventory are not criteria for electrical or functional equivalency; they are provided for reference only.
