API Delevan 6446-012 Equivalent & Substitute Parts

Part Overview

The API Delevan 6446-012 is a laminated core power transformer rated at 20VA with dual primary and secondary windings. This through-hole mounted component provides selectable output configurations via parallel (6.3V, 3.3A) or series (12.6V, 1.6A) winding connections, with 4000Vrms isolation rating.

The 6446-012 carries an obsolete product status. Identifying equivalent substitute parts is necessary to maintain design continuity and ensure component availability for new production builds, repairs, and legacy system support.

Substitute Part Grouping Explanation

Substitute parts for the 6446-012 are identified based on electrical and mechanical parameter equivalence. The critical substitution criteria are:

• Identical power rating (20VA)
• Matching primary voltage selection (115V, 230V dual configuration)
• Identical secondary voltage outputs in both parallel (6.3V) and series (12.6V) modes
• Equivalent current delivery capacity (3.3A parallel, 1.6A series)
• Matching core type (laminated)
• Identical winding configuration (dual primary, dual secondary)
• Compatible mounting and termination (through-hole PC pin)
• Equivalent isolation voltage (4000Vrms)
• Physical dimensions within tolerance for PCB layout compatibility

The API Delevan 6446R-012 meets all these criteria and qualifies as a direct substitute.

Parameter Comparison

Engineering Selection Recommendations

The API Delevan 6446R-012 is the direct substitute for the obsolete 6446-012. All electrical and mechanical parameters are identical, ensuring functional equivalence in circuit applications.

The 6446R-012 carries active product status, providing assured long-term availability and supply chain continuity. The part is ROHS3 compliant, meeting current environmental and regulatory requirements for new designs and manufacturing processes. The original 6446-012 is RoHS non-compliant, making the 6446R-012 the appropriate choice for applications requiring regulatory compliance.

Both parts share identical isolation voltage, winding configuration, and physical form factor, eliminating the need for PCB layout modifications or circuit redesign when transitioning from the obsolete to the active part number.

Frequently Asked Questions (FAQ)

Q: Can the 6446R-012 replace the 6446-012 in existing designs?

A: Yes. The 6446R-012 is electrically and mechanically identical to the 6446-012. All voltage ratings, current capacities, winding configurations, and physical dimensions match exactly. No circuit modifications or PCB layout changes are required.

Q: What is the difference between the 6446-012 and 6446R-012?

A: The primary differences are product status and regulatory compliance. The 6446-012 is obsolete and RoHS non-compliant. The 6446R-012 is active and ROHS3 compliant. Electrical and mechanical specifications are identical.

Q: Are there any compatibility concerns with the through-hole PC pin termination?

A: No. Both parts use identical through-hole PC pin termination. Pin spacing, hole diameter, and mounting requirements are the same, ensuring direct PCB compatibility.

Q: Can I use either parallel or series winding configuration with the substitute part?

A: Yes. The 6446R-012 maintains the dual primary and dual secondary winding configuration of the original part, supporting both parallel (6.3V, 3.3A) and series (12.6V, 1.6A) output modes without modification.

Q: Is the 4000Vrms isolation rating maintained in the substitute part?

A: Yes. The 6446R-012 provides the same 4000Vrms isolation voltage as the original 6446-012.

Q: What is the inventory status of the substitute part?

A: The 6446R-012 is in active production with 1004 units currently in stock, ensuring reliable availability for procurement.
