• Output current capacity: 850mA (parallel) and 425mA (series)
• Isolation voltage: 1500Vrms minimum
• Mounting type: Through hole with PC pin termination
• Physical envelope: Compatible with 41.28mm L x 33.32mm W x 33.32mm H maximum dimensions
• Laminated core construction

Parameter Comparison

No substitute parts are available for comparison at this time. Any future equivalent components must satisfy all parameters listed in the Key Parameters table to ensure functional compatibility with existing circuit designs utilizing the 6054-056.

Engineering Selection Recommendations

The API Delevan 6054-056 is classified as obsolete. When replacement components are required, selection must prioritize:

1. Exact electrical parameter matching across all voltage and current specifications
2. Identical mounting configuration (through hole) and termination style (PC pin)
3. Compliance requirements appropriate to the target application
4. Physical dimensions compatible with existing PCB layouts and enclosure constraints
5. Isolation voltage rating of 1500Vrms or higher

Substitution decisions should be based solely on the ability of candidate components to meet these specified parameters without modification to circuit design or PCB layout.

Frequently Asked Questions (FAQ)

Q: What makes a transformer a valid substitute for the 6054-056? A: A substitute must provide identical electrical performance: 24VA power rating, dual primary windings supporting 115V and 230V input, dual secondary windings delivering 28V at 850mA (parallel) or 56V at 425mA (series), and 1500Vrms isolation. The component must also feature through-hole mounting with PC pin termination and fit within the specified physical dimensions.

Q: Can transformers with different winding configurations be used as substitutes? A: No. The 6054-056 requires dual primary and dual secondary windings to support its specified voltage and current configurations. Single-winding or alternative configurations cannot replicate this functionality.

Q: Are there compliance considerations when selecting a substitute? A: The original 6054-056 is RoHS non-compliant. Depending on application requirements and regulatory jurisdiction, a substitute may need to meet current RoHS standards or other applicable compliance certifications. This must be evaluated based on end-use requirements.

Q: How critical is the physical size when finding a substitute? A: Physical dimensions are critical for through-hole mounted components. The 6054-056 occupies 41.28mm L x 33.32mm W x 33.32mm H. Substitutes must fit within these constraints to avoid PCB redesign and mechanical rework.

Q: What is the significance of the laminated core type? A: The laminated core construction is integral to the transformer's electrical performance and efficiency characteristics. Substitutes must maintain this core type to ensure equivalent performance in the target application.
