Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 6444-036 is determined by strict equivalence across the following critical parameters:

• Power rating: 5VA
• Primary voltage options: 115V and 230V
• Secondary voltage configuration: Parallel 18V and Series 36V output capability
• Output current capacity: Parallel 280mA and Series 140mA
• Winding configuration: Dual primary and dual secondary
• Core construction: Laminated
• Mounting and termination: Through-hole with PC pin termination
• Isolation voltage: 4000Vrms
• Physical footprint: 41.28mm L × 33.32mm W

The 6444R-036 meets all these criteria and qualifies as a direct substitute based on identical electrical specifications and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The 6444R-036 is the direct equivalent for the obsolete 6444-036. Both parts are manufactured by API Delevan Inc. and share identical electrical and mechanical specifications. The primary distinction is product status and regulatory compliance: the 6444R-036 is currently active in production and meets ROHS3 compliance requirements, whereas the 6444-036 is obsolete and non-compliant with current RoHS standards.

For new designs or system replacements, the 6444R-036 is the appropriate selection. For legacy system maintenance where the original 6444-036 is specified, the 6444R-036 provides full functional compatibility with the added benefit of current manufacturing status and enhanced regulatory compliance.

Frequently Asked Questions (FAQ)

Q: Can the 6444R-036 be used as a direct replacement for the 6444-036?

A: Yes. The 6444R-036 is electrically and mechanically identical to the 6444-036. All voltage ratings, current capacities, winding configurations, isolation specifications, and physical dimensions are equivalent. The parts are interchangeable in circuit applications.

Q: What is the difference between the 6444-036 and 6444R-036?

A: The primary differences are product status and compliance certification. The 6444-036 is obsolete and RoHS non-compliant. The 6444R-036 is an active production part that meets ROHS3 compliance standards. Electrical and mechanical specifications are identical.

Q: Are there any compatibility concerns when substituting the 6444R-036 for the 6444-036?

A: No compatibility concerns exist. Both parts feature identical through-hole PC pin termination, matching physical footprints, and equivalent electrical performance across all specified voltage and current parameters.

Q: Why is the 6444-036 listed as obsolete?

A: The 6444-036 has been superseded by the 6444R-036, which maintains full functional equivalence while offering improved regulatory compliance and active manufacturing support.

Q: Can these transformers be configured for different voltage outputs?

A: Yes. Both the 6444-036 and 6444R-036 feature dual primary and dual secondary windings, allowing configuration for either 18V parallel output (280mA maximum) or 36V series output (140mA maximum). Primary voltage selection between 115V and 230V is also available.
