Key Parameters

Substitute Part Grouping Explanation

The substitute part is grouped based on direct equivalence of electrical and mechanical parameters, including: input voltage range, output voltage, output current, output power, number of outputs, converter type, mounting style, package type, regulatory compliance, operational temperature rating, and RoHS status. The substitute part must match on these key parameters to ensure compatibility and direct replacement capability.

Parameter Comparison

Engineering Selection Recommendations

The main part, VOF-15-9, is obsolete and thus not suitable for new designs where long-term availability is a requirement. EML15US09-P from XP Power is an active part and shares direct equivalence in electrical characteristics, mounting type, and packaging. Both parts are RoHS compliant and possess relevant regulatory approvals. Product status, compliance, and certifications are critical in selection, and EML15US09-P meets these criteria as a direct substitute.

Frequently Asked Questions (FAQ)

Q: What electrical parameters determine if EML15US09-P can substitute VOF-15-9?
A: Substitution is validated by identical input voltage range (85 ~ 264 VAC), output voltage (9V), output current (1.67A), and output power (15W).

Q: Are mounting methods and package types compatible?
A: Both parts use through hole mounting and a 4-DIP module package, ensuring mechanical compatibility.

Q: Are there differences in operating temperature range?
A: VOF-15-9 operates at 0°C ~ 60°C (with derating); EML15US09-P provides a wider -20°C ~ 70°C (with derating) range. Operational suitability is determined by system requirements.

Q: What certifications and agency approvals support substitution?
A: VOF-15-9 is approved by CB Scheme, EN, IEC, SIQ, TUV, UL. EML15US09-P carries CE, cULus, TUV approvals. Selection must reference specified system regulatory requirements.

Q: Is RoHS compliance maintained when substituting EML15US09-P for VOF-15-9?
A: Both parts are RoHS compliant as specified: VOF-15-9 (RoHS Compliant) and EML15US09-P (ROHS3 Compliant).

Q: Are there significant dimensional differences?
A: VOF-15-9: 2.76" x 1.91" x 0.91" (70.0mm x 48.6mm x 23.1mm); EML15US09-P: 2.44" x 1.21" x 0.96" (62.0mm x 30.7mm x 24.4mm). Mechanical compatibility depends strictly on physical constraints in the target application.

Q: What is the importance of matching inventory and product status?
A: Inventory and product status (active vs. obsolete) impact long-term sourcing and support but do not affect electrical or mechanical compatibility.
