6497-024 Power Transformer Laminated 130VA Quick Connect

Part Overview

The 6497-024 is a laminated core power transformer rated at 130VA with dual primary and secondary windings, manufactured by API Delevan Inc. This component is classified as obsolete and no longer in active production. The transformer features dual voltage primary inputs (115V, 230V) and configurable secondary outputs (parallel 12V at 10.8A or series 24V at 5.4A), with chassis mount installation and solder/quick connect termination options.

Due to its obsolete status, locating replacement inventory from original sources becomes increasingly difficult. Identifying equivalent active production alternatives ensures design continuity and supply chain reliability for applications requiring this transformer specification.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 6497-024 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 dual configuration)
• Matching secondary voltage outputs (parallel 12V, series 24V)
• Equivalent maximum output current specifications (parallel 10.8A, series 5.4A)
• Identical isolation voltage rating (4000Vrms)
• Matching core type (laminated)
• Identical winding configuration (dual primary, dual secondary)

Mechanical Parameters:

• Compatible mounting type (chassis mount)
• Compatible termination style (solder, quick connect)
• Physical dimensions within acceptable tolerance for board layout

The 6497R-024 meets all specified electrical and mechanical parameters while offering active production status and improved compliance certifications.

Engineering Selection Recommendations

The 6497R-024 serves as the direct active production equivalent to the obsolete 6497-024. Selection of the 6497R-024 is supported by the following engineering factors:

Product Status: The 6497R-024 maintains active production status with confirmed inventory availability (1100 pieces), whereas the 6497-024 is classified as obsolete. Active production status ensures continued supply chain access and manufacturing support.

Regulatory Compliance: The 6497R-024 is ROHS3 compliant, meeting current environmental and material restriction standards. The original 6497-024 is non-compliant with modern regulatory requirements. For applications subject to RoHS directives or customer compliance mandates, the 6497R-024 is the appropriate selection.

Export Classification: The 6497R-024 carries EAR99 classification with HTSUS code 8504.31.4065, providing clear export and tariff documentation. The obsolete classification of the 6497-024 creates uncertainty in regulatory documentation.

Electrical and Mechanical Equivalence: All specified electrical parameters (power rating, voltage inputs/outputs, current ratings, isolation voltage, winding configuration) are identical between the two parts. Physical dimensions are compatible with minor orientation differences (length and width dimensions are transposed by 1.59mm, within typical PCB layout tolerance). Mounting type and termination style are identical.

For new designs or replacement applications, the 6497R-024 is the appropriate selection. For legacy systems requiring exact physical orientation matching, dimensional verification against specific board layouts is necessary.

Frequently Asked Questions (FAQ)

Q: Can the 6497R-024 directly replace the 6497-024 in existing designs?

A: The 6497R-024 is electrically and functionally equivalent to the 6497-024. All voltage inputs, outputs, current ratings, and isolation specifications are identical. Physical dimensions are compatible; however, length and width dimensions are transposed by 1.59mm. Board layouts with tight dimensional constraints should be verified for clearance compatibility.

Q: What is the significance of the "R" designation in the 6497R-024 part number?

A: The "R" designation indicates the active production revision of the original 6497-024 design. The 6497R-024 incorporates ROHS3 compliance and updated export classifications while maintaining electrical and mechanical compatibility with the original specification.

Q: Are there differences in termination compatibility between these parts?

A: Both the 6497-024 and 6497R-024 feature identical termination options: solder and quick connect. Existing wiring harnesses and connection methods are compatible between the two parts.

Q: What is the impact of RoHS3 compliance on system integration?

A: ROHS3 compliance affects material composition and manufacturing processes but does not alter electrical performance or functional characteristics. Systems designed for RoHS-compliant components benefit from the 6497R-024 selection. Systems with no RoHS requirements experience no functional difference.

Q: Are there inventory considerations for selecting between these parts?

A: The 6497-024 is obsolete with limited remaining inventory (1072 pieces reported). The 6497R-024 is in active production with confirmed inventory (1100 pieces). For applications requiring long-term supply continuity, the 6497R-024 is the appropriate selection.

Q: How do the physical dimensions affect PCB layout decisions?

A: The 6497-024 measures 73.03mm length by 71.44mm width. The 6497R-024 measures 71.44mm length by 73.03mm width. The dimensions are transposed but the overall footprint area and height (85.73mm) remain identical. PCB layouts with directional constraints should account for this 1.59mm orientation difference.

Q: What certifications and classifications apply to the 6497R-024?

A: The 6497R-024 carries ROHS3 compliance certification, EAR99 export classification, and HTSUS tariff code 8504.31.4065. These designations support regulatory compliance documentation and international trade requirements.
