Key Parameters

Substitute Part Grouping Explanation

The API Delevan 6448R-024 qualifies as a direct substitute for the 6448-024 based on the following critical parameters:

• Identical power rating of 56VA
• Matching primary voltage inputs (115V, 230V)
• Identical secondary voltage outputs in both parallel (12V) and series (24V) configurations
• Matching maximum output currents (4.66A parallel, 2.33A series)
• Identical dual primary and dual secondary winding architecture
• Matching core type (laminated)
• Identical mounting type (through hole) and termination style (PC pin)
• Matching isolation voltage rating (4000Vrms)
• Identical physical dimensions and weight

The primary distinction between these parts is product status and compliance certification. The 6448R-024 represents an active production variant with RoHS3 compliance, whereas the 6448-024 is obsolete and RoHS non-compliant.

Parameter Comparison

Engineering Selection Recommendations

The 6448R-024 is the appropriate selection for applications requiring the 6448-024 specification profile. The substitute part maintains complete electrical and mechanical compatibility while offering the advantage of active production status and RoHS3 compliance certification. For new designs or systems requiring regulatory compliance with current environmental standards, the 6448R-024 is the designated equivalent. For legacy system maintenance where the original 6448-024 is no longer available, the 6448R-024 provides direct functional replacement without circuit redesign or board layout modification.

Frequently Asked Questions (FAQ)

Q: Can the 6448R-024 be used as a direct replacement for the 6448-024 in existing applications?

A: Yes. The 6448R-024 maintains identical electrical specifications, winding configuration, voltage ratings, current ratings, and physical dimensions. Through-hole mounting and PC pin termination are unchanged, allowing direct board-level substitution.

Q: What is the significance of the RoHS3 compliance difference?

A: The 6448R-024 meets RoHS3 environmental compliance standards, restricting hazardous substances in manufacturing. The 6448-024 does not carry this certification. For applications subject to environmental regulations or customer compliance requirements, the 6448R-024 is the appropriate choice.

Q: Are there any performance differences between these transformers?

A: No. Both parts deliver identical power handling (56VA), voltage transformation ratios, current capacity, isolation voltage, and core characteristics. Performance in circuit operation is equivalent.

Q: Why is the 6448-024 listed as obsolete?

A: The 6448-024 has been superseded by the 6448R-024 in the manufacturer's active product line. The 6448R-024 provides the same functionality with updated compliance certifications and continued production support.

Q: Are the physical footprints identical for PCB mounting?

A: Yes. Both transformers share identical dimensions (76.20mm L × 64.60mm W × 45.97mm H) and through-hole mounting configuration, requiring no PCB layout changes for substitution.
