• Output current (1.25A)
• Output wattage (15W)
• Universal AC input voltage range
• Number of outputs (1)
• Mechanical mounting (Through Hole)
• Package / case (4-DIP Module)
• Safety approvals and certifications
• RoHS compliance
• Operating temperature (with derating or improvement included)
• Regulation parameters (line and load)
• Application suitability (ITE Commercial)

Only substitute components that fully meet or exceed these specified parameters are included.

Parameter Comparison

Engineering Selection Recommendations

The VOF-15-12 is obsolete, sparking a requirement for direct substitutes. VOF-15B-S12 is classified as active and maintains equivalence in output voltage, output current, output wattage, mounting type, package, and application. Regulatory and compliance certifications are present for both models, with RoHS conformance explicitly stated. Physical dimensions and efficiency differ but remain within the required operational parameters. The VOF-15B-S12 features extended operating temperature and updated certification standards.

Frequently Asked Questions (FAQ)

Q1: What parameters must match for an equivalent substitute to be valid for the VOF-15-12?
A: Required matches include output voltage (12V), output current (1.25A), output wattage (15W), number of outputs (1), input voltage compatibility, mounting configuration, package/case type, and certifications.

Q2: Are there any differences in package or mounting between VOF-15-12 and VOF-15B-S12?
A: Both use 4-DIP module packaging with through hole mounting, ensuring footprint compatibility.

Q3: Does the substitute VOF-15B-S12 offer different efficiency or operating temperature characteristics?
A: VOF-15B-S12 offers increased efficiency (84.5% vs. 80%) and a wider operating temperature range (-25°C ~ 70°C vs. 0°C ~ 60°C).

Q4: Are certifications between the original and substitute models comparable?
A: Both models are certified for safety and electromagnetic compatibility under international standards with some updates; VOF-15B-S12 includes additional FCC and 62368-1 standards.

Q5: How does RoHS compliance influence substitute selection?
A: RoHS compliance is maintained across both models, ensuring continued adherence to environmental regulations in component selection.

Q6: Can VOF-15B-S12 be directly used in designs where VOF-15-12 was originally specified?
A: VOF-15B-S12 matches all critical electrical, mechanical, and regulatory requirements for direct substitution within the constraints provided.
