Key Parameters

Substitute Part Grouping Explanation

Substitution logic for the VOFM-5-5 open frame AC/DC converter is strictly based on the following parameters:

• Electrical: Input voltage range, output voltage, output current, output power, line regulation, load regulation, efficiency
• Mechanical: Mounting type, package/case, size/dimension
• Environmental: Operating temperature range
• Compliance/Standards: Applications (medical), approvals, RoHS status, MSL

Only substitutes meeting or exceeding these criteria are included.

Parameter Comparison

Engineering Selection Recommendations

VOFM-5-5 is an obsolete product. Substitute part VMS-20-5 is active, RoHS3 Compliant, and has equivalent or enhanced certifications, including CB Scheme, EN, IEC, UL, and additional SIQ and TUV. The mechanical form factor (through hole, 4-DIP module) and application compatibility (medical) are maintained. MSL levels are identical. All selections are based strictly on available certification, compliance, and status details.

Frequently Asked Questions (FAQ)
