6497-028 Laminated Power Transformer Equivalent & Substitute Parts

Part Overview

The 6497-028 is a 130VA laminated core power transformer manufactured by API Delevan Inc., designed for chassis mount applications with dual primary and secondary windings. The unit supports configurable output voltage in parallel (14V) or series (28V) modes with corresponding current ratings of 9.2A and 4.6A respectively. The part is classified as obsolete, necessitating identification of active equivalent components for new designs and ongoing production requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 6497-028 is based on electrical and mechanical parameter equivalence. The primary substitution criterion is functional compatibility across all specified electrical parameters: power rating (130VA), primary voltage configuration (115V/230V dual), secondary voltage modes (14V parallel, 28V series), output current capacity (9.2A parallel, 4.6A series), winding configuration (dual primary and secondary), isolation voltage (4000Vrms), and mounting type (chassis mount).

Mechanical compatibility is verified through termination style consistency (Solder and Quick Connect options) and physical envelope compatibility. The substitute part 6497R-028 maintains identical electrical specifications and mounting characteristics while incorporating dimensional variation within the same physical envelope class.

The key differentiating factor between the main part and substitute is product status and regulatory compliance. The 6497-028 is obsolete and RoHS non-compliant, while the 6497R-028 is active production and ROHS3 compliant.

Parameter Comparison

Engineering Selection Recommendations

The 6497R-028 is the direct active production equivalent of the 6497-028. All electrical parameters, winding configurations, and functional specifications are identical. The substitute part is manufactured by the same original equipment manufacturer (API Delevan Inc.) and maintains full compatibility with applications designed for the 6497-028.

Selection of the 6497R-028 is supported by two primary engineering factors: (1) the 6497-028 is classified as obsolete, making long-term supply unavailable; and (2) the 6497R-028 achieves ROHS3 compliance, meeting current regulatory requirements for electronic component manufacturing and distribution in restricted substance directives.

The dimensional variation between the two parts (length and width transposed by 1.59mm) remains within the same physical envelope classification and does not affect mounting compatibility or circuit board layout for chassis mount applications.

Frequently Asked Questions (FAQ)

Q: Are the 6497-028 and 6497R-028 electrically interchangeable?

A: Yes. Both parts are rated at 130VA with identical primary voltage options (115V, 230V), secondary voltage configurations (14V parallel, 28V series), output current ratings (9.2A parallel, 4.6A series), isolation voltage (4000Vrms), and winding configurations (dual primary and secondary). Electrical performance is equivalent.

Q: What is the difference between these two transformer models?

A: The primary differences are product status and regulatory compliance. The 6497-028 is obsolete and RoHS non-compliant. The 6497R-028 is active production and ROHS3 compliant. Electrical and functional specifications are identical.

Q: Will the 6497R-028 fit in the same physical space as the 6497-028?

A: Yes. Both parts are chassis mount with identical height (85.73mm maximum seated). The length and width dimensions are transposed (73.03mm x 71.44mm versus 71.44mm x 73.03mm), but both fit within the same physical envelope classification for chassis mount applications.

Q: Are the termination options the same on both parts?

A: Yes. Both the 6497-028 and 6497R-028 support identical termination styles: Solder and Quick Connect options.

Q: Why should I use the 6497R-028 instead of the 6497-028?

A: The 6497-028 is obsolete, which restricts availability for new production and long-term supply. The 6497R-028 is the active equivalent from the same manufacturer with identical electrical specifications and improved ROHS3 compliance status.

Q: Can I use the 6497R-028 as a replacement in existing equipment using the 6497-028?

A: Yes. The 6497R-028 is functionally equivalent with identical electrical ratings, winding configurations, and mounting type. The part is suitable for replacement applications.
