API Delevan 6448-020 Equivalent & Substitute Parts

Part Overview

The API Delevan 6448-020 is a laminated core power transformer rated at 56VA with dual primary and secondary windings. This through-hole mounted component features 4000Vrms isolation and supports both 115V and 230V primary configurations with parallel (10V, 5.6A) and series (20V, 2.8A) secondary output options. The 6448-020 is classified as obsolete, making identification of active equivalent parts essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 6448-020 is determined by electrical and mechanical parameter equivalence. The primary selection criteria are:

• Identical power rating (56VA)
• Matching primary voltage configuration (115V, 230V dual)
• Matching secondary voltage outputs (parallel 10V, series 20V)
• Matching secondary current capacity (parallel 5.6A, series 2.8A)
• Identical core type (laminated)
• Identical mounting configuration (through hole, PC pin termination)
• Equivalent isolation voltage (4000Vrms)
• Compatible physical envelope (76.20mm L × 64.60mm W × 45.97mm H)

The 6448R-020 meets all these criteria and represents the active production equivalent to the obsolete 6448-020.

Parameter Comparison

Engineering Selection Recommendations

The 6448R-020 is the direct active equivalent to the obsolete 6448-020. Both components share identical electrical specifications and physical form factors, ensuring direct functional compatibility in existing circuit designs. The primary distinction is product status and regulatory compliance: the 6448R-020 is actively manufactured and ROHS3 compliant, whereas the 6448-020 is obsolete and RoHS non-compliant. For new designs and ongoing production requiring compliance with current environmental regulations, the 6448R-020 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-020 be used as a direct replacement for the 6448-020?

A: Yes. The 6448R-020 is electrically and mechanically identical to the 6448-020. All electrical parameters, physical dimensions, and mounting configurations are equivalent, enabling direct substitution without circuit modification.

Q: What is the primary difference between these two parts?

A: The 6448-020 is obsolete and RoHS non-compliant, while the 6448R-020 is an active production part with ROHS3 compliance. Electrical and mechanical specifications are identical.

Q: Are there any compatibility concerns when substituting the 6448-020 with the 6448R-020?

A: No compatibility concerns exist. Both parts feature identical through-hole PC pin termination, physical envelope, and electrical characteristics. PCB layouts and circuit designs require no modification.

Q: What does the "R" designation in the 6448R-020 indicate?

A: The "R" designation indicates the revised, active production version of the original 6448 series transformer, incorporating updated compliance standards.

Q: Is the 6448R-020 available in the same packaging as the 6448-020?

A: Both parts use identical through-hole mounting with PC pin termination. Physical dimensions and weight are equivalent.
