Key Parameters

Substitute Part Grouping Explanation

Substitution is determined exclusively by matching or exceeding the critical electrical and mechanical parameters: input voltage range, output voltage, output current, output power, application, mounting type, compliance (RoHS), and applicable safety approvals. Only parts with identical or stricter specifications for these categories are considered viable substitutes.

Key substitution parameters:

• Input voltage range
• Output voltage and current
• Output power
• Application type
• Mounting type
• Regulatory approvals
• RoHS compliance
• Package / form factor (noting any differences)

Parameter Comparison

Engineering Selection Recommendations

VAF505 is discontinued (Obsolete), making component substitution essential for design continuity. The listed substitute TUHS5F05 is available (Active). Both VAF505 and TUHS5F05 are RoHS3 Compliant and share essential regulatory certifications (CE, cURus). Parameter parity includes input/output voltage, current, power, mounting type, and line/load regulation. The substitute achieves a higher efficiency and wider operating temperature, reflecting stricter or equivalent compliance as indicated by provided approvals. The package and enclosure type differ; mechanical fit and enclosure requirements must be evaluated using provided dimensions and package type.

Frequently Asked Questions (FAQ)

Q1: What are the critical parameters for substituting VAF505 with TUHS5F05?
A1: Input voltage range, output voltage, output current, output power, application, mounting type, regulatory approvals (CE, cURus), and RoHS compliance.

Q2: Are there differences in mechanical size or package that could impact compatibility?
A2: Yes. VAF505 uses a 5-DIP module; TUHS5F05 uses a 6-DIP module with different dimensions. Review mechanical layouts for form factor compatibility.

Q3: Are the safety and environmental compliance standards maintained?
A3: Both models are RoHS3 Compliant, and both have CE and cURus approvals. VAF505 adds TUV approval, which is not listed for the TUHS5F05.

Q4: Will thermal performance or efficiency differ in a like-for-like replacement?
A4: TUHS5F05 offers higher efficiency (79% vs. 77%) and a wider operating temperature range. Review application requirements for these capability increases.

Q5: Does mounting method require changes?
A5: Both products use through-hole mounting; check pin compatibility and PCB layout against provided package data.
