Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 6446-010 is determined by strict equivalence across the following critical parameters:

• Electrical Performance: Identical power rating (20VA), primary voltage options (115V/230V), secondary voltage configuration (Parallel 5V/Series 10V), and output current capacity (Parallel 4A/Series 2A)
• Core Architecture: Laminated core construction with dual primary and dual secondary windings
• Isolation Specification: 4000Vrms isolation voltage
• Physical Form Factor: Through-hole mounting with PC pin termination, matching dimensional envelope (57.15mm L × 47.63mm W × 36.50mm H max)
• Mechanical Compatibility: Identical weight and footprint for direct board-level replacement

The 6446R-010 meets all substitution criteria, providing complete functional and mechanical compatibility while offering improved product lifecycle status and regulatory compliance.

Parameter Comparison

Engineering Selection Recommendations

The 6446R-010 is the direct substitute for the obsolete 6446-010. Both components share identical electrical specifications, core architecture, and physical form factor, enabling direct board-level replacement without circuit modification.

The 6446R-010 offers the additional advantage of Active product status, ensuring continued availability and supply chain stability. The component achieves ROHS3 compliance, meeting current regulatory requirements for new designs and manufacturing environments subject to RoHS directives.

Selection between these parts is determined by application context: the 6446-010 remains suitable only for legacy system maintenance where existing inventory is available; the 6446R-010 is the standard choice for new designs, production restocking, and systems requiring regulatory compliance documentation.

Frequently Asked Questions (FAQ)

Q: Can the 6446R-010 directly replace the 6446-010 in existing assemblies?

A: Yes. The 6446R-010 provides complete functional and mechanical equivalence. Identical electrical ratings, winding configuration, isolation voltage, and through-hole PC pin termination enable direct substitution without circuit redesign or board layout modification.

Q: What is the significance of the product status difference?

A: The 6446-010 is classified as Obsolete, indicating discontinued manufacturing and limited future availability. The 6446R-010 maintains Active status, ensuring reliable supply, technical support, and compliance with current manufacturing standards.

Q: Does the RoHS3 compliance of the 6446R-010 affect compatibility?

A: No. RoHS3 compliance indicates adherence to current environmental and material restriction directives. This certification does not alter electrical performance or mechanical compatibility. The 6446R-010 is suitable for applications in regulated environments requiring RoHS documentation.

Q: Are there any dimensional or mounting differences?

A: No. Both components share identical physical dimensions (57.15mm L × 47.63mm W × 36.50mm H maximum seated height), weight (0.9 lb), and through-hole PC pin termination. Board-level mounting is identical.

Q: What output configurations are available?

A: Both components provide dual secondary winding configuration supporting two output modes: Parallel connection yields 5V at 4A maximum; Series connection yields 10V at 2A maximum. Selection depends on application voltage and current requirements.
