API Delevan 6495-020 Equivalent & Substitute Parts

Part Overview

The API Delevan 6495-020 is a laminated core power transformer rated at 43VA with dual primary and secondary windings. The unit features selectable output configurations (parallel 10V at 4.4A or series 20V at 2.2A) and dual primary inputs (115V or 230V). This transformer is designed for chassis mount applications with solder and quick connect termination options.

The 6495-020 carries an obsolete product status. Identification of equivalent substitute parts is necessary to maintain system continuity, ensure component availability, and support ongoing maintenance and repair operations for legacy equipment.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the API Delevan 6495-020 is based on electrical and mechanical parameter equivalence. The substitute part must satisfy the following criteria:

Electrical Parameters:

• Identical power rating (43VA)
• Matching primary voltage inputs (115V, 230V dual configuration)
• Matching secondary voltage outputs in both parallel (10V) and series (20V) configurations
• Equivalent maximum output current specifications (parallel 4.4A, series 2.2A)
• Identical isolation voltage rating (4000Vrms)
• Dual primary and dual secondary winding configuration

Mechanical Parameters:

• Identical core type (laminated)
• Matching physical dimensions (79.38mm L x 52.39mm W)
• Matching seated height (68.26mm maximum)
• Identical mounting type (chassis mount)
• Compatible termination style (solder and quick connect)

The API Delevan 6495R-020 meets all specified electrical and mechanical parameters and qualifies as a direct substitute.

Parameter Comparison

Engineering Selection Recommendations

The API Delevan 6495R-020 is the direct substitute for the obsolete 6495-020 model. All electrical and mechanical parameters are identical, ensuring functional equivalence in circuit applications.

Product Status Consideration: The 6495-020 is classified as obsolete, indicating discontinued manufacturing and limited availability. The 6495R-020 maintains active product status with current manufacturing support and documented inventory availability.

Regulatory Compliance: The 6495R-020 is ROHS3 compliant and carries ECCN classification EAR99 with HTSUS code 8504.31.4065. The original 6495-020 is non-compliant with RoHS standards. For applications subject to RoHS regulatory requirements or procurement policies mandating RoHS compliance, the 6495R-020 is the appropriate selection.

Availability and Support: The 6495R-020 is available in active inventory with documented stock levels. This ensures reliable procurement for new designs, repairs, and system upgrades.

Frequently Asked Questions (FAQ)

Q: Can the 6495R-020 be used as a direct replacement for the 6495-020 in existing equipment?

A: Yes. The 6495R-020 is electrically and mechanically equivalent to the 6495-020. All voltage ratings, current specifications, winding configurations, physical dimensions, and mounting characteristics are identical. Direct substitution is supported without circuit modification.

Q: What is the difference between the 6495-020 and 6495R-020 part numbers?

A: The 6495R-020 is the active production equivalent of the obsolete 6495-020. The "R" designation indicates a revised or replacement version. Both units are manufactured by API Delevan Inc. and share identical electrical and mechanical specifications.

Q: Does the RoHS compliance difference affect compatibility?

A: RoHS compliance affects regulatory and procurement requirements, not functional compatibility. The 6495R-020 is ROHS3 compliant, making it suitable for applications subject to RoHS directives or procurement policies. The 6495-020 is non-compliant. For new designs or systems requiring RoHS compliance, the 6495R-020 is the required selection.

Q: Are the physical dimensions identical between both models?

A: Yes. Both the 6495-020 and 6495R-020 share identical physical dimensions: 79.38mm length, 52.39mm width, and 68.26mm maximum seated height. Both are chassis mount configurations with identical footprints and mounting interfaces.

Q: Can both models be used interchangeably in parallel or series winding configurations?

A: Yes. Both models support identical dual primary (115V/230V) and dual secondary (10V parallel or 20V series) winding configurations. Output current ratings are identical in both configurations: 4.4A maximum in parallel mode and 2.2A maximum in series mode.

Q: What termination options are available for both models?

A: Both the 6495-020 and 6495R-020 provide identical termination options: solder and quick connect. Component selection depends on circuit board design and assembly requirements.

Q: Is the isolation voltage rating the same for both models?

A: Yes. Both models provide 4000Vrms isolation voltage rating, ensuring equivalent electrical safety and isolation performance in applications requiring high-voltage isolation.
