Key Parameters

Substitute Part Grouping Explanation

Substitution of the 6447-012 is determined by strict equivalence across the following critical parameters:

• Power Rating: 30VA (exact match required)
• Core Type: Laminated (exact match required)
• Primary Voltage: 115V, 230V dual configuration (exact match required)
• Secondary Voltage: Parallel 6.3V, Series 12.6V dual configuration (exact match required)
• Secondary Current Capacity: Parallel 4.8A, Series 2.4A (exact match required)
• Winding Configuration: Dual primary, dual secondary (exact match required)
• Mounting Type: Through Hole (exact match required)
• Termination Style: PC Pin (exact match required)
• Physical Envelope: 66.68mm L × 55.55mm W × 39.67mm H maximum (exact match required)
• Isolation Voltage: 4000Vrms (exact match required)

The 6447R-012 meets all substitution criteria as a direct equivalent with identical electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

The 6447R-012 is a direct functional equivalent to the 6447-012 across all electrical and mechanical parameters. The primary distinction is product lifecycle status and regulatory compliance:

• 6447-012: Obsolete status indicates discontinued production. RoHS non-compliance reflects legacy manufacturing standards.
• 6447R-012: Active product status ensures ongoing availability and supply chain continuity. ROHS3 compliance aligns with current environmental and regulatory requirements for new designs and procurement cycles.

For applications requiring component replacement or new procurement, the 6447R-012 provides identical performance with the advantage of active production status and modern compliance certifications.

Frequently Asked Questions (FAQ)

Q: Can the 6447R-012 be used as a direct replacement for the 6447-012?

A: Yes. The 6447R-012 matches all electrical and mechanical specifications of the 6447-012, including power rating, voltage configurations, current capacity, winding arrangement, mounting type, termination style, physical dimensions, and isolation voltage.

Q: What is the difference between these two parts?

A: The 6447R-012 is an active product with ROHS3 compliance, while the 6447-012 is obsolete and RoHS non-compliant. Electrical and mechanical performance are identical.

Q: Are there any physical compatibility concerns when substituting the 6447R-012 for the 6447-012?

A: No. Both parts share identical dimensions (66.68mm L × 55.55mm W × 39.67mm H maximum), through-hole mounting type, and PC pin termination style. PCB footprints and mounting requirements are identical.

Q: Does the 6447R-012 support the same voltage configurations as the 6447-012?

A: Yes. Both parts support dual primary windings (115V or 230V selectable) and dual secondary windings (6.3V parallel or 12.6V series selectable) with identical current ratings.

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

A: The 6447R-012 meets ROHS3 environmental standards, making it suitable for applications subject to modern regulatory requirements. The 6447-012, being RoHS non-compliant, reflects legacy manufacturing. For new designs or regulated applications, the 6447R-012 is the appropriate selection.
