Substitute Part Grouping Explanation

Substitute part identification for the VOF-15-48 utilizes only those models meeting the following definitive electrical, mechanical, and regulatory criteria:

• Input voltage range: 85 ~ 264 VAC
• Output characteristics: Single output, 48V, minimum 310mA, power rating 15W
• Mounting type and package: Through Hole, 4-DIP Module
• Application and features: ITE (Commercial), Universal Input
• Regulatory approvals and standards: Must match or exceed CB Scheme, EN, IEC, UL equivalents and relevant standard numbers
• Environmental compliance: RoHS status and Moisture Sensitivity Level (MSL)

Only products fully matching these parameters qualify as direct substitutes.

Parameter Comparison

Engineering Selection Recommendations

The recommended substitute VOF-15B-S48 is active and fully RoHS compliant, with matching regulatory approvals and identical mounting type, package, and core electrical specifications as VOF-15-48. The operating temperature range and relevant certification standards meet or exceed those of the obsolete part, ensuring regulatory and compliance continuity.

Frequently Asked Questions (FAQ)

Q1: What are the critical parameters for selecting an equivalent part for VOF-15-48?
A1: Only input voltage range, output voltage/current, wattage, mounting type, package, regulatory approvals, application, operating temperature, and environmental compliance are considered.

Q2: Does VOF-15B-S48 have the same mounting format as VOF-15-48?
A2: Both parts use Through Hole mounting and a 4-DIP Module package, ensuring mechanical compatibility.

Q3: Are there differences in output capabilities between these models?
A3: Both provide a 48V single output. VOF-15B-S48 offers a slightly higher maximum output current (320mA vs. 310mA) while maintaining a 15W power rating.

Q4: What regulatory certifications must substitutes match?
A4: Substitutes must maintain matching or updated CB Scheme, EN, IEC, UL certifications and listed standards numbers.

Q5: Is the operating temperature range compatible for direct replacement?
A5: VOF-15B-S48 provides an extended range (-25°C ~ 70°C) compared to the original (0°C ~ 60°C), covering all applications supported by VOF-15-48.

Q6: Is the substitute VOF-15B-S48 RoHS compliant and suitable for existing inventory processes?
A6: Both VOF-15-48 and VOF-15B-S48 are RoHS compliant and have identical Moisture Sensitivity Level (MSL) ratings.
