Key Parameters

Substitute Part Grouping Explanation

Substitution of the 6497-012 is determined by electrical and mechanical parameter equivalence across the following criteria:

Electrical Parameters:

• Identical power rating (130VA)
• Matching primary voltage selections (115V, 230V dual configuration)
• Identical secondary voltage outputs in both parallel (6.3V) and series (12.6V) configurations
• Matching output current specifications (Parallel 20.6A, Series 10.3A)
• Equivalent isolation voltage rating (4000Vrms)
• Identical winding configuration (dual primary, dual secondary)

Mechanical Parameters:

• Laminated core construction type
• Chassis mount form factor
• Compatible termination options (solder and quick connect)
• Physical dimensions within tolerance (height 85.73mm maximum)

Regulatory & Availability:

• Active product status with current manufacturing
• Compliance certifications applicable to the application environment

The 6497R-012 meets all electrical and mechanical substitution criteria while offering improved regulatory compliance and active production status.

Parameter Comparison

Engineering Selection Recommendations

The 6497R-012 is the direct functional equivalent of the 6497-012 with complete electrical and mechanical parameter alignment. Selection of the 6497R-012 is supported by the following engineering factors:

Product Status: The 6497R-012 maintains active manufacturing status, ensuring reliable supply chain availability and long-term component sourcing for production and field replacement applications.

Regulatory Compliance: The 6497R-012 is RoHS3 compliant, meeting current environmental and hazardous substance restrictions. The original 6497-012 is non-compliant with RoHS standards. For applications subject to RoHS requirements or future regulatory transitions, the 6497R-012 provides compliance assurance.

Electrical Equivalence: All electrical parameters are identical, including power rating, voltage configurations, current ratings, isolation voltage, and winding architecture. Direct functional substitution is supported without circuit modification.

Mechanical Compatibility: Physical dimensions, mounting type, and termination options are identical, enabling direct mechanical interchange in existing designs and installations.

Series Designation: The 6497R designation indicates the revised production series incorporating regulatory updates while maintaining backward compatibility with the original 6497 series specifications.

Frequently Asked Questions (FAQ)

Q: Can the 6497R-012 be used as a direct replacement for the 6497-012 in existing equipment?

A: Yes. The 6497R-012 provides complete electrical and mechanical equivalence. All voltage ratings, current capacities, winding configurations, mounting interfaces, and termination options are identical. Direct substitution is supported without circuit or mechanical modifications.

Q: What is the primary difference between the 6497-012 and 6497R-012?

A: The 6497R-012 is the active production equivalent with RoHS3 compliance and current manufacturing status. The 6497-012 is obsolete and non-compliant with RoHS standards. Electrical and mechanical specifications are identical.

Q: Are the physical dimensions identical between both models?

A: The height dimension is identical at 85.73mm maximum seated height. The length and width dimensions are transposed (6497-012: 73.03mm L x 71.44mm W; 6497R-012: 71.44mm L x 73.03mm W), representing a 90-degree rotational orientation. Both configurations fit the same mounting envelope for chassis mount applications.

Q: Does the 6497R-012 support the same voltage configurations as the 6497-012?

A: Yes. Both models support identical primary voltage selection (115V or 230V) and identical secondary voltage outputs through parallel (6.3V, 20.6A) and series (12.6V, 10.3A) winding configurations.

Q: What does RoHS3 compliance mean for the 6497R-012?

A: RoHS3 compliance indicates the 6497R-012 meets current Restriction of Hazardous Substances directives, limiting the use of specified hazardous materials in electrical and electronic equipment. This is required for products sold in regulated markets and for applications subject to environmental compliance standards.

Q: Is the 6497R-012 suitable for new design applications?

A: Yes. The 6497R-012 is an active product with current manufacturing support, making it appropriate for new designs requiring a 130VA laminated core transformer with dual primary and secondary windings, 4000Vrms isolation, and chassis mount construction.

Q: What is the inventory status for both models?

A: The 6497-012 (obsolete) has 955 pieces in stock. The 6497R-012 (active) has 889 pieces in stock. For long-term applications, the active 6497R-012 is recommended due to continued manufacturing availability.
