API Delevan 6025-056 Equivalent & Substitute Parts

Part Overview

The API Delevan 6025-056 is a laminated core power transformer rated at 12VA with dual primary and secondary windings. This through-hole mounted component provides selectable output configurations through series/parallel winding connections, delivering either 28V at 440mA (parallel) or 56V at 220mA (series) from 115V or 230V primary inputs.

The 6025-056 carries an obsolete product status. Locating equivalent substitute parts is necessary to support ongoing maintenance, repair, and new design requirements where this transformer specification remains applicable.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 6025-056 is determined by strict equivalence across the following critical parameters:

Electrical Specifications:

• Power rating: 12VA
• Primary voltage inputs: 115V and 230V selectable
• Secondary voltage outputs: 28V (parallel) and 56V (series) configurations
• Output current capacity: 440mA (parallel) and 220mA (series)
• Isolation voltage: 2500Vrms
• Winding configuration: Dual primary and dual secondary

Mechanical Specifications:

• Core type: Laminated
• Mounting method: Through hole
• Termination: PC pin
• Physical envelope: 47.63mm L × 39.67mm W × 36.50mm H maximum

Compliance Considerations:

• RoHS status
• REACH compliance status

Parts meeting all electrical and mechanical parameters listed above qualify as direct substitutes. Deviations in any specified parameter disqualify a part from this equivalence group.

Parameter Comparison

Engineering Selection Recommendations

The 6025R-056 is a direct electrical and mechanical equivalent to the 6025-056. All functional parameters—power rating, voltage configurations, current capacity, core type, winding arrangement, mounting method, termination style, and physical dimensions—are identical between the two parts.

The primary distinction lies in product lifecycle status and regulatory compliance:

6025-056 (Obsolete): This part carries obsolete status, indicating discontinued manufacturing and limited availability. RoHS non-compliance reflects its legacy design baseline.

6025R-056 (Active): This part is in active production with current availability (759 units in stock versus 1000 units for the obsolete variant). The 6025R-056 meets ROHS3 compliance requirements, aligning with modern regulatory standards for electronic components.

For new designs, maintenance applications, or situations requiring regulatory compliance documentation, the 6025R-056 is the appropriate selection. The electrical and mechanical compatibility is complete, with no circuit redesign or mechanical rework required.

Frequently Asked Questions (FAQ)

Q: Can the 6025R-056 replace the 6025-056 in existing circuit designs?

A: Yes. The 6025R-056 provides identical electrical performance and mechanical fit. All voltage inputs, output configurations, current ratings, isolation specifications, and physical mounting parameters match the original 6025-056. Direct substitution is possible without circuit modification.

Q: What is the significance of the "R" designation in the 6025R-056 part number?

A: The "R" suffix indicates a revised or updated version of the original 6025 series design. In this case, the 6025R-056 maintains full electrical and mechanical compatibility while incorporating ROHS3 compliance and active production status.

Q: Are there any compliance differences between these parts?

A: Yes. The 6025-056 is RoHS non-compliant, while the 6025R-056 meets ROHS3 standards. Both parts are REACH Unaffected and carry the same ECCN and HTSUS classifications. For applications requiring RoHS compliance documentation, the 6025R-056 is required.

Q: Do these transformers support both series and parallel output configurations?

A: Yes. Both the 6025-056 and 6025R-056 feature dual secondary windings that can be configured for either series connection (56V at 220mA) or parallel connection (28V at 440mA). The primary winding is also dual, supporting both 115V and 230V input selection.

Q: What is the isolation voltage rating, and why is it important?

A: Both parts provide 2500Vrms isolation between primary and secondary windings. This isolation rating defines the maximum voltage differential that can be safely applied between input and output circuits without risk of breakdown or component failure.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both transformers have identical dimensions of 47.63mm length × 39.67mm width × 36.50mm maximum seated height, with identical weight of 0.7 lb (317.51 g). PCB layout and mechanical mounting require no modification when substituting between these parts.
