Equivalent & Substitute Parts for YAS505

Part Overview

The Cosel USA, Inc. YAS505 is an enclosed AC/DC converter in the power supply component category, featuring a single 5V DC output at 1A with a universal input range (85 ~ 264 VAC, 110 ~ 370 VDC). This power supply is designed for ITE (commercial) applications and is RoHS compliant. The YAS505 is currently listed as obsolete, making it necessary to identify alternative AC/DC converter models that fulfill identical or stricter requirements for electrical performance, mechanical compatibility, compliance, and certifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the YAS505 AC/DC converter is based strictly on key parameters that define electrical and mechanical compatibility:

• Output voltage: 5V
• Output current: 1A
• Power rating: 5W
• Input voltage range: universal AC input and specified DC range
• Number of outputs: 1
• Mounting type: Through Hole
• Enclosure: Enclosed style
• Electrical regulation: Line regulation 20mV, load regulation 40mV
• Environmental: RoHS Compliance, approval agency certifications
• Package/case compatibility
• Operating temperature and efficiency (as specified)

Only parts matching these parameters are considered valid substitutes.

Engineering Selection Recommendations

When selecting a replacement for the obsolete YAS505 AC/DC converter, the TUHS5F05 from Cosel USA, Inc. meets the essential electrical specifications, RoHS compliance, and maintains applicable approval agency certifications. The TUHS5F05 is in active production status and adheres to universal input requirements, with identical output voltage, current, and power ratings. Package/case form factor, approval agency certification coverage, and any relevant compliance distinctions should be evaluated according to the application’s constraints and provided certifications.

Frequently Asked Questions (FAQ)

Q1: What are the key criteria for substituting the YAS505 AC/DC converter?
A1: The key criteria are matching the output voltage (5V), output current (1A), power rating (5W), input voltage range (universal AC/DC), mounting type (Through Hole), number of outputs (1), enclosure type, regulation values, compliance (RoHS), and approvals.

Q2: Do the substitute parts have the same package dimensions as the YAS505?
A2: The TUHS5F05 has a different package and dimensions (6-DIP Module, 1.13" L x 0.69" W x 0.50" H) compared to the YAS505 (5-DIP Module, 2.28" L x 1.77" W x 0.77" H). Review mechanical compatibility with the target application.

Q3: How does the approval agency certification compare between parts?
A3: The YAS505 holds CE, CSA, cURus, TUV, and UL certifications. The TUHS5F05 holds CE and cURus certifications.

Q4: Are both parts RoHS compliant?
A4: Yes, both the YAS505 and TUHS5F05 are RoHS compliant as specified.

Q5: Are there differences in environmental or operational ratings relevant to substitution?
A5: The TUHS5F05 offers a wider specified operating temperature range (-40°C ~ 85°C) and higher efficiency (79%) compared to the YAS505 (-10°C ~ 70°C, 65%).

Q6: What should be considered regarding mounting and mechanical fit?
A6: Mounting type remains Through Hole for both parts; attention must be given to differences in package/case format and dimensions.
