Key Parameters

Substitute Part Grouping Explanation

Substitution is strictly determined using the following allowed electrical and mechanical parameters: input voltage range, output voltage, maximum output current, application suitability, mounting type, package/case, efficiency, regulatory approvals, RoHS compliance, line and load regulation, operating temperature range, and moisture sensitivity level (MSL). The substitute part TUHS10F24 is included on the basis that its specified parameters match those required for function and regulatory compliance.

Parameter Comparison

Engineering Selection Recommendations

Selection of TUHS10F24 as a substitute for VAF1024 is supported by matched application category, equivalent output voltage and current, universal input capability, identical line and load regulation, matching mounting type, and ROHS3 compliance. TUHS10F24 is currently in Active status, whereas VAF1024 is Obsolete. Both parts are certified by CE and cURus, and share ECCN and HTSUS codes. Users must verify regulatory agency approvals based on the required standards; TUV is only listed for VAF1024.

Frequently Asked Questions (FAQ)

Q1: What input and output parameters must match for a substitute power supply?
A1: The input voltage range, output voltage, and maximum output current must match strictly. Both VAF1024 and TUHS10F24 provide 24V output at 450mA with universal input voltage ranges.

Q2: Are the mounting types equivalent for direct replacement?
A2: Both models utilize through-hole mounting, but the package/case format differs (5-DIP Module versus 6-DIP Module). Dimensional compatibility must be reviewed according to PCB design requirements.

Q3: Does regulatory approval differ between these parts?
A3: VAF1024 is approved by CE, cURus, and TUV. TUHS10F24 is approved by CE and cURus. TUV approval is not listed for TUHS10F24.

Q4: Is RoHS compliance consistent between the original and substitute model?
A4: Both VAF1024 and TUHS10F24 are ROHS3 Compliant.

Q5: Is there any difference in operational temperature and efficiency?
A5: TUHS10F24 features a wider operating temperature range and higher efficiency (87% vs. 81%). Specific requirements should be evaluated as per these provided values.

Q6: Will dimensional differences affect physical compatibility?
A6: Size and package variations can affect fitting. VAF1024 is larger in all dimensions compared to TUHS10F24, which uses a 6-DIP Module format. Direct replacement requires checking mechanical constraints in the design.

Q7: Are ECCN and HTSUS codes for compliance management identical?
A7: Both models list ECCN as EAR99 and HTSUS as 8504.40.9510, ensuring matched export and customs classification.
