VAA1005 Equivalent & Substitute Parts Reference

Part Overview

The VAA1005 by Cosel USA, Inc. is an open frame AC/DC converter in the 10W VAA series, providing a single 5V 2A output with input compatibility for 85 ~ 132 VAC or 110 ~ 170 VDC. This obsolete product is RoHS3 compliant, with an operating temperature of -10°C to 70°C (with derating), 76% efficiency, and is designed for ITE (Commercial) applications using through hole mounting in a 5-DIP Module package. Since the VAA1005 is no longer in production, it is necessary to identify alternative models that meet the same functional and regulatory requirements for continued design or field support.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts are determined by direct equivalence in core electrical and mechanical parameters essential to operation and compliance. Substitution requires an exact match on: output voltage, output current, output power, input voltage range (must be equivalent or wider), application type (ITE Commercial), RoHS compliance, mounting type, operational temperature range that meets or exceeds the main part, and matching regulatory approvals (e.g., cURus). Only models with these explicitly defined characteristics are eligible as substitutes for VAA1005.

Parameter Comparison

Engineering Selection Recommendations

The primary selection rationale is the end-of-life, obsolete status of the VAA1005. The TUHS10F05 remains an active product and directly matches the required core parameters for voltage, current, power, compliance, and approvals. Both models are RoHS3 compliant and carry cURus certification for ITE (Commercial) applications.

Frequently Asked Questions (FAQ)

Q1: What are the most critical parameters when substituting VAA1005?
A1: The key parameters are output voltage (5V), output current (2A), overall power (10W), input voltage range, application type (ITE Commercial), mounting style (through hole), RoHS compliance, and certifications.

Q2: Is the TUHS10F05 mechanically and electrically compatible with VAA1005?
A2: Both support through hole mounting, a single 5V/2A output, and equivalent power levels. Dimensional and package case differences (5-DIP vs. 6-DIP) must be considered for fit within the target design.

Q3: Are there any differences in regulatory approvals?
A3: Both VAA1005 and TUHS10F05 have cURus approval. TUHS10F05 additionally holds CE certification.

Q4: Does the wider input voltage range or higher temperature range of TUHS10F05 impact substitution?
A4: The substitute’s input and temperature range fully encompass the requirements of the main part, meeting or exceeding all operational constraints.

Q5: Is there any difference in RoHS compliance or Moisture Sensitivity Level (MSL)?
A5: Both parts are ROHS3 compliant and have a Moisture Sensitivity Level of "Not Applicable".
