YAS1012 Equivalent & Substitute Parts Reference

Part Overview

The YAS1012 from Cosel USA, Inc. is an enclosed AC/DC converter with a single 12V output rated at 900mA, delivering up to 11W. Designed for ITE (Commercial) applications, it features universal input (85–264 VAC or 110–370 VDC), through-hole mounting, and approvals from CE, CSA, cURus, TUV, and UL. This model is classified as obsolete, necessitating the identification of substitute models to ensure continued design support and repair compatibility in existing systems where the YAS1012 is used.

Key Parameters

Substitute Part Grouping Explanation

Substitution is based strictly on matching key parameters: identical output voltage (12V), output current (900mA), number of outputs (1), enclosed type, through-hole mounting, universal input range supporting industrial AC and DC voltages, equivalent or smaller package, and appropriate regulatory approvals and RoHS compliance. Substitute models must adhere precisely to these requirements for form, fit, and function in existing designs.

Key parameters for substitution:

• Voltage - Output 1
• Current - Output (Max)
• Number of Outputs
• Voltage - Input
• Type
• Mounting Type
• Package / Case
• Size / Dimension
• Approval Agency
• RoHS Status

Parameter Comparison

Engineering Selection Recommendations

Selection of TUHS10F12 as an equivalent substitute for YAS1012 is supported by identical output voltage, output current, mounting method, and RoHS compliance. Both parts have CE and cURus regulatory approvals. Note differences in case size, package, and additional agency certifications; substitute selection is permissible only where the substitution parameters align with system requirements and regulatory acceptance criteria for the original application.

Frequently Asked Questions (FAQ)

Q1: What criteria determine whether TUHS10F12 is an appropriate substitute for YAS1012?
A1: Substitution is determined by equivalent key parameters: output voltage (12V), output current (900mA), number of outputs (1), mounting type (through hole), and enclosure type. Compliance status and primary regulatory approvals are also primary considerations.

Q2: Are there any mechanical differences between YAS1012 and TUHS10F12 that affect compatibility?
A2: TUHS10F12 features a 6-DIP module with smaller dimensions (33.0mm x 21.8mm x 15.0mm) compared to YAS1012’s 5-DIP module (65.0mm x 45.0mm x 21.0mm). System layout must accommodate the substitute's package footprint.

Q3: Are all safety and compliance certifications identical between the two models?
A3: Both YAS1012 and TUHS10F12 are CE and cURus certified. YAS1012 also includes CSA, TUV, and UL certifications not listed for TUHS10F12.

Q4: Does the output power difference (11W vs 10W) affect substitution eligibility?
A4: The substitute TUHS10F12 is rated at 10W while YAS1012 is rated at 11W. Output voltage and current specifications are identical, ensuring functional equivalence within specified loads.

Q5: What RoHS status is associated with each part?
A5: YAS1012 is RoHS Compliant and TUHS10F12 is ROHS3 Compliant. Both meet the requirements for lead-free and restricted substances.
