API Delevan Inc. 6497-020 Power Transformer Equivalent & Substitute Parts

Part Overview

The API Delevan Inc. 6497-020 is a laminated core power transformer rated at 130VA with dual primary and secondary windings. This component is designed for chassis mount applications with solder and quick connect termination options. The part is classified as obsolete, making identification of active equivalent components essential for ongoing system support and new design implementations.

The 6497-020 provides flexible voltage configurations with primary inputs of 115V or 230V and secondary outputs in parallel (10V at 13A) or series (20V at 6.5A) configurations. Due to its obsolete status, sourcing active alternatives ensures design continuity and supply chain reliability.

Substitute Part Grouping Explanation

Substitution of the 6497-020 is based on electrical and mechanical parameter equivalence. The primary criteria for substitution include:

Electrical Parameters:

• Identical power rating (130VA)
• Matching primary voltage inputs (115V, 230V)
• Matching secondary voltage outputs in both parallel (10V) and series (20V) configurations
• Equivalent maximum output current specifications (Parallel 13A, Series 6.5A)
• Identical isolation voltage rating (4000Vrms)
• Matching winding configuration (dual primary, dual secondary, no center tap)

Mechanical Parameters:

• Identical core type (laminated)
• Equivalent mounting type (chassis mount)
• Compatible termination style (solder and quick connect)
• Physical dimensions within tolerance (length, width, and height)

The 6497R-020 meets all electrical and mechanical substitution criteria while offering the advantage of active product status and improved regulatory compliance.

Engineering Selection Recommendations

The 6497R-020 serves as the direct active equivalent to the obsolete 6497-020 power transformer. Selection of the 6497R-020 is supported by the following engineering factors:

Product Status: The 6497R-020 maintains active product status, ensuring continued availability and manufacturer support. The 6497-020 is classified as obsolete, presenting supply chain risk for new procurements and long-term system maintenance.

Regulatory Compliance: The 6497R-020 is ROHS3 compliant, meeting current environmental and hazardous substance restrictions. The 6497-020 is non-compliant with RoHS standards, which may restrict use in applications subject to regulatory requirements.

Electrical Equivalence: All electrical parameters are identical between the two components, including power rating, voltage configurations, current ratings, isolation voltage, and winding configuration. This ensures functional interchangeability in existing circuit designs.

Mechanical Compatibility: Physical dimensions and mounting characteristics are equivalent, with length and width dimensions transposed (73.03mm x 71.44mm versus 71.44mm x 73.03mm). Height and mounting type remain identical, supporting direct mechanical substitution in chassis mount applications.

Export Classification: The 6497R-020 carries HTSUS classification 8504.31.4065 and ECCN EAR99 designation, providing clear regulatory classification for procurement and export purposes.

Frequently Asked Questions (FAQ)

Q: Can the 6497R-020 be used as a direct replacement for the 6497-020 in existing designs?

A: Yes. The 6497R-020 provides electrical and mechanical equivalence to the 6497-020. All voltage ratings, current specifications, winding configurations, isolation voltage, and mounting characteristics are identical. The components are functionally interchangeable.

Q: What is the significance of the dimension difference between the two parts?

A: The length and width dimensions are transposed between the two parts (73.03mm x 71.44mm for the 6497-020 versus 71.44mm x 73.03mm for the 6497R-020). The height dimension remains identical at 85.73mm. This transposition does not affect functional performance or standard chassis mount applications, as both dimensions fall within the same physical envelope.

Q: Why is the 6497-020 classified as obsolete?

A: The 6497-020 is no longer in active production. The 6497R-020 represents the current active equivalent in the API Delevan Inc. product line. For new designs and ongoing system support, the 6497R-020 is the recommended selection.

Q: Does the RoHS3 compliance of the 6497R-020 affect electrical performance?

A: No. RoHS3 compliance relates to material composition and hazardous substance restrictions, not electrical performance. The 6497R-020 maintains identical electrical specifications to the 6497-020 while meeting current environmental standards.

Q: Are the termination styles compatible between the two parts?

A: Yes. Both the 6497-020 and 6497R-020 support identical termination styles: solder and quick connect. Existing wiring and connection methods are compatible with the substitute part.

Q: What is the inventory status of these components?

A: The 6497-020 has 899 pieces available as new original stock. The 6497R-020 has 796 pieces available as new original stock. For new procurements, the 6497R-020 is the recommended selection due to its active product status.

Q: Can the 6497R-020 be used in applications requiring RoHS compliance?

A: Yes. The 6497R-020 is ROHS3 compliant, making it suitable for applications subject to RoHS regulatory requirements. The 6497-020 is non-compliant and may not be acceptable in such applications.
