Substitute Part Grouping Explanation

Substitution of the obsolete 6495-024 with the active 6495R-024 is based on electrical and mechanical parameter equivalence. Both units share identical specifications across the following critical parameters:

Electrical Equivalence Criteria:

• Identical power rating (43VA)
• Identical primary voltage options (115V, 230V dual input)
• Identical secondary voltage configurations (parallel 12V, series 24V)
• Identical dual primary and dual secondary winding architecture
• Identical isolation voltage rating (4000Vrms)
• Identical center tap configuration (none)

Mechanical Equivalence Criteria:

• Identical mounting type (chassis mount)
• Identical termination style (solder, quick connect)
• Identical physical dimensions (79.38mm L x 52.39mm W x 68.26mm H max)

Compliance Difference: The 6495R-024 achieves RoHS3 compliance and carries EAR99 export classification, whereas the 6495-024 is non-compliant and obsolete. This substitution enables compliance with current regulatory requirements while maintaining full functional compatibility.

Parameter Comparison

Engineering Selection Recommendations

The 6495R-024 serves as the direct active equivalent to the obsolete 6495-024. Selection of the 6495R-024 is supported by the following engineering factors:

Functional Compatibility: All electrical parameters required for circuit operation are identical between the two units. The transformer will function identically in existing circuit designs without modification to PCB layout, wiring, or control logic.

Regulatory Compliance: The 6495R-024 achieves RoHS3 compliance, meeting current environmental and material restriction requirements. The obsolete 6495-024 does not meet these standards. For new production, field service replacements, and systems subject to regulatory oversight, the 6495R-024 is the appropriate selection.

Physical Interchangeability: Identical mounting dimensions and termination styles ensure direct mechanical substitution without enclosure or assembly redesign.

Current Capacity Enhancement: The 6495R-024 provides increased parallel output current capacity (6.3A versus 3.6A), offering improved performance margin in parallel configuration applications while maintaining identical series output specifications.

Availability and Support: The 6495R-024 is classified as active product status with current manufacturing support, ensuring long-term component availability and supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can the 6495R-024 be used as a direct replacement for the 6495-024 in existing designs?

A: Yes. The 6495R-024 is electrically and mechanically equivalent to the 6495-024 across all critical parameters. No circuit modifications, PCB changes, or wiring alterations are required. The transformer will operate identically in existing applications.

Q: What is the difference in current output between these two models?

A: In parallel configuration, the 6495R-024 provides 6.3A maximum output current compared to 3.6A for the 6495-024. In series configuration, both units provide 1.8A maximum output current. The increased parallel current capacity of the 6495R-024 represents an enhancement that does not affect compatibility with existing designs.

Q: Why is the 6495-024 classified as obsolete?

A: The 6495-024 has been discontinued by the manufacturer. The 6495R-024 is the active replacement model. For new production and ongoing support, the 6495R-024 should be specified.

Q: Are the physical dimensions identical between these models?

A: Yes. Both units have identical dimensions: 79.38mm length, 52.39mm width, and 68.26mm maximum seated height. Both use chassis mount configuration with solder and quick connect termination options.

Q: What is the significance of RoHS3 compliance on the 6495R-024?

A: RoHS3 compliance indicates the 6495R-024 meets current environmental and material restriction standards. This is required for products sold in regulated markets and for systems subject to environmental compliance requirements. The obsolete 6495-024 does not meet these standards.

Q: Are the winding configurations identical?

A: Yes. Both units feature dual primary windings and dual secondary windings with no center tap. Both support identical voltage configurations: 115V or 230V primary input, with 12V parallel or 24V series secondary output.

Q: What is the isolation voltage rating?

A: Both the 6495-024 and 6495R-024 provide 4000Vrms isolation voltage, ensuring identical electrical isolation performance in both models.
