Key Parameters

Substitute Part Grouping Explanation

Substitution is based strictly on matching the following key parameters: output voltage, maximum output current, power rating, input voltage range, universal input feature, number of outputs, mounting style, and relevant compliance (RoHS, approval agencies). Substitute parts included meet or exceed these criteria within the specific product category.

Key parameters for grouping:

• Voltage - Output 1 (24V)
• Current - Output (Max) (220mA)
• Power (Watts) (5W)
• Voltage - Input (universal range)
• Number of Outputs (1)
• Mounting Type (Through Hole)
• Application (ITE Commercial)
• RoHS Status
• Approval Agency alignment

Parameter Comparison

Engineering Selection Recommendations

VAF524 is classified as obsolete. Replacement selection should be based on matching output voltage, output current, input voltage range, power rating, mounting type, RoHS compliance, and approval agency coverage. TUHS5F24 is an active Cosel USA, Inc. alternative that meets all matching criteria, including product compliance and certifications (CE, cURus). RoHS3 compliance is maintained in both models.

Frequently Asked Questions (FAQ)

Q: What makes TUHS5F24 a suitable substitute for VAF524?
A: TUHS5F24 matches the output voltage (24V), maximum output current (220mA), power rating (5W), input voltage range, number of outputs, and mounting type of VAF524, supporting direct substitution in compatible applications within the same product category.

Q: Are there differences in packaging or mechanical footprint between VAF524 and TUHS5F24?
A: VAF524 uses a 5-DIP module (2.85" x 1.26" x 0.79") while TUHS5F24 uses a 6-DIP module (1.13" x 0.69" x 0.50"). Mounting method remains through-hole.

Q: Do substitute parts maintain environmental and regulatory compliance?
A: Both VAF524 and TUHS5F24 are ROHS3 Compliant and carry CE and cURus certifications.

Q: Is approval agency coverage consistent between the two models?
A: VAF524 is approved by CE, cURus, and TUV. TUHS5F24 is approved by CE and cURus.

Q: How does operating temperature range affect substitution?
A: TUHS5F24 supports a wider operating temperature range (-40°C ~ 85°C with derating) compared to VAF524, which operates in -10°C ~ 71°C with derating.

Q: Is pinout and footprint compatibility guaranteed?
A: Package / case type and mechanical dimensions differ. Review the mechanical compatibility against application requirements.

Q: Is there a difference in efficiency between VAF524 and TUHS5F24?
A: TUHS5F24 offers 83% efficiency, compared to 81% for VAF524.
