Key Parameters

Substitute Part Grouping Explanation

Substitution of the 6448-028 is determined by strict equivalence across the following critical parameters:

• Power rating: 56VA
• Primary voltage configuration: 115V, 230V dual winding
• Secondary voltage output: Parallel 14V / Series 28V dual winding
• Output current capacity: Parallel 4A / Series 2A
• Core type: Laminated
• Mounting configuration: Through hole with PC pin termination
• Physical dimensions: 76.20mm L x 64.60mm W x 45.97mm H maximum
• Isolation voltage: 4000Vrms

The 6448R-028 meets all these parameters while offering improved product status and regulatory compliance.

Parameter Comparison

Engineering Selection Recommendations

The 6448R-028 is the direct equivalent substitute for the obsolete 6448-028. Both components share identical electrical specifications, physical dimensions, and mounting characteristics. The primary distinction is product status and regulatory compliance: the 6448-028 is obsolete and RoHS non-compliant, while the 6448R-028 is active production and ROHS3 compliant. For new designs and systems requiring ongoing component availability, the 6448R-028 is the appropriate selection. For legacy system maintenance where original specifications must be preserved, the 6448-028 remains functionally equivalent where inventory permits.

Frequently Asked Questions (FAQ)

Q: Can the 6448R-028 be used as a direct replacement for the 6448-028?

A: Yes. The 6448R-028 provides identical electrical performance and physical compatibility. All voltage ratings, current capacities, winding configurations, and mounting specifications are equivalent.

Q: What is the difference between the 6448-028 and 6448R-028?
