Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 6448-012 is determined by strict equivalence across the following critical parameters:

• Power rating: 56VA
• Primary winding configuration: Dual windings with 115V/230V selectability
• Secondary winding configuration: Dual windings with parallel (6.3V) and series (12.6V) output capability
• Output current capacity: 8.8A (parallel) and 4.4A (series)
• Isolation voltage: 4000Vrms
• Mounting and termination: Through-hole PC pin configuration
• Physical dimensions: 76.20mm L × 64.60mm W × 45.97mm H (seated)
• Core type: Laminated construction

The 6448R-012 meets all these criteria, providing direct functional equivalence while offering improved product status and regulatory compliance.

Parameter Comparison

Engineering Selection Recommendations

The 6448R-012 is the direct equivalent substitute for the obsolete 6448-012. Both components share identical electrical specifications, physical dimensions, and mounting characteristics. The 6448R-012 offers two significant advantages:

1. Active product status: The 6448R-012 remains in active production, ensuring long-term availability and supply chain continuity.
2. Regulatory compliance: The 6448R-012 meets ROHS3 compliance requirements, whereas the 6448-012 is RoHS non-compliant. This distinction is critical for applications subject to environmental and regulatory standards.

For new designs or system replacements, the 6448R-012 is the appropriate selection. For legacy system maintenance where RoHS compliance is not mandated, either part may be used interchangeably based on availability.

Frequently Asked Questions (FAQ)

Q: Can the 6448R-012 be used as a direct replacement for the 6448-012 in existing assemblies?

A: Yes. The 6448R-012 is electrically and mechanically identical to the 6448-012. All electrical parameters, winding configurations, output ratings, isolation voltage, and physical dimensions are equivalent. Direct substitution is possible without circuit modification.

Q: What is the difference between the 6448 and 6448R series designations?

A: The 6448R designation indicates the revised version of the 6448 series. The 6448R-012 incorporates ROHS3 compliance and maintains active production status, while the original 6448-012 is obsolete and RoHS non-compliant.

Q: Are there any compatibility concerns with PC pin termination between these parts?

A: No. Both the 6448-012 and 6448R-012 use identical PC pin termination styles and through-hole mounting configurations. PCB footprints and assembly processes remain unchanged.

Q: Does the 6448R-012 support the same voltage configurations as the 6448-012?

A: Yes. Both parts feature dual primary windings (115V/230V selectable) and dual secondary windings (6.3V parallel or 12.6V series output). Voltage configuration flexibility is identical.

Q: What is the significance of ROHS3 compliance on the 6448R-012?

A: ROHS3 compliance indicates the 6448R-012 meets current environmental and hazardous substance restrictions. This is essential for applications in regulated industries and markets with mandatory RoHS requirements. The 6448-012, being RoHS non-compliant, may not be acceptable for such applications.
