Key Parameters

Substitute Part Grouping Explanation

Substitution of the 6445-016 with the 6445R-016 is valid based on electrical and mechanical parameter equivalence. The substitute part maintains identical specifications across all critical selection criteria:

Key Parameters for Substitution Validation:

• Electrical rating (10VA)
• Primary voltage input options (115V, 230V)
• Secondary voltage outputs (8V parallel, 16V series)
• Secondary current capacity (1.25A parallel, 620mA series)
• Core and winding configuration (Laminated, Dual/Dual)
• Isolation voltage (4000Vrms)
• Physical mounting interface (Through Hole, PC Pin termination)
• Dimensional compatibility (47.63mm L × 39.67mm W × 36.50mm H max)

The substitute part provides full functional equivalence for applications currently utilizing the obsolete 6445-016.

Frequently Asked Questions (FAQ)

Q: Can the 6445R-016 directly replace the 6445-016 in existing designs?

A: Yes. The 6445R-016 provides electrical equivalence across all parameters including voltage ratings, current capacity, winding configuration, and isolation specifications. Physical dimensions and mounting interfaces are identical, ensuring direct compatibility in through-hole PCB applications.

Q: What is the significance of the RoHS compliance difference?

A: The 6445-016 is non-compliant with RoHS standards, while the 6445R-016 is ROHS3 compliant. For new designs and procurement in jurisdictions with RoHS material restrictions, the 6445R-016 is the required choice.

Q: Are the electrical ratings equivalent between both parts?

A: Yes. Both transformers are rated at 10VA with identical primary voltage options (115V, 230V), secondary voltage configurations (8V parallel / 16V series), and secondary current capacities (1.25A parallel / 620mA series).

Q: How do the physical dimensions compare?

A: The parts are dimensionally identical. Both measure 47.63mm length by 39.67mm width, with a maximum seated height of 36.50mm. No modification to PCB layouts or mechanical assemblies is required for substitution.

Q: What inventory levels are available?

A: The 6445-016 has 929 pieces in stock. The 6445R-016, the active substitute, has 762 pieces available. For long-term supply continuity, procurement should transition to the 6445R-016.
