API Delevan 6015-028 Laminated Power Transformer Equivalent & Substitute Parts

Part Overview

The API Delevan 6015-028 is a laminated core power transformer rated at 12VA with a single primary winding (115V) and dual secondary windings (14V parallel / 28V series configuration). This through-hole mounted component is designed for PC pin termination and provides 2500Vrms isolation.

The 6015-028 carries an obsolete product status. Locating equivalent or substitute components is necessary for ongoing system support, maintenance, and new design implementations where this transformer specification remains applicable.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 6015-028 is determined by strict equivalence across the following electrical and mechanical parameters:

Electrical Equivalence Criteria:

• Primary voltage: 115V
• Secondary voltage configuration: Dual windings with 14V parallel and 28V series output
• Power capacity: 12VA
• Output current ratings: 840mA (parallel) and 420mA (series)
• Isolation voltage: 2500Vrms
• Winding configuration: Single primary, dual secondary, no center tap

Mechanical Equivalence Criteria:

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

Parts meeting all these criteria are classified as direct substitutes. Variations in product status, compliance certifications, or series designation do not affect functional substitutability when all electrical and mechanical parameters remain identical.

Parameter Comparison

Engineering Selection Recommendations

6015R-028 as Primary Substitute:

The API Delevan 6015R-028 is a direct functional equivalent to the 6015-028. All electrical parameters (voltage, current, power, isolation) and mechanical parameters (dimensions, mounting, termination) are identical. The 6015R-028 is the active production variant within the same product family.

Compliance Considerations:

The 6015-028 is RoHS non-compliant, while the 6015R-028 is RoHS3 compliant. For applications subject to RoHS directives or procurement policies requiring RoHS compliance, the 6015R-028 is the appropriate selection. For legacy systems or applications without RoHS requirements, either part functions identically.

Availability and Product Status:

The 6015-028 is obsolete but currently has 1082 units in stock. The 6015R-028 is active production with 765 units available. For new designs or long-term system support, the 6015R-028 ensures continued availability and manufacturer support.

Frequently Asked Questions (FAQ)

Q: Can the 6015R-028 replace the 6015-028 in existing designs?

A: Yes. The 6015R-028 is electrically and mechanically identical to the 6015-028. All voltage ratings, current capacities, winding configurations, isolation specifications, and physical dimensions match exactly. Direct substitution is possible without circuit modification.

Q: What is the difference between the 6015-028 and 6015R-028?

A: The primary differences are product status and compliance certification. The 6015-028 is obsolete and RoHS non-compliant. The 6015R-028 is an active production part with RoHS3 compliance. Functionally and electrically, both parts are identical.

Q: Does the RoHS3 compliance of the 6015R-028 affect performance?

A: No. RoHS3 compliance indicates the materials and manufacturing process meet environmental standards. It does not alter electrical performance, voltage ratings, current capacity, or isolation characteristics. Performance specifications remain identical.

Q: Are the physical dimensions identical between both parts?

A: Yes. Both the 6015-028 and 6015R-028 have identical dimensions: 47.63mm length × 39.67mm width × 36.50mm height (seated). Both use through-hole mounting with PC pin termination. PCB layout and mechanical fit are identical.

Q: Which part should be selected for new designs?

A: The 6015R-028 is recommended for new designs. It is an active production part with manufacturer support, RoHS3 compliance, and confirmed ongoing availability. The 6015-028, being obsolete, may face future supply constraints.

Q: Can both parts be used interchangeably in the same circuit?

A: Yes. Both parts have identical electrical specifications: 115V primary, 14V/28V secondary (parallel/series), 12VA power rating, 2500Vrms isolation, and 840mA/420mA output current ratings. Interchangeable use is supported without circuit redesign.

Q: What is the isolation voltage specification, and does it differ between parts?

A: Both parts provide 2500Vrms isolation voltage. This specification is identical and unchanged between the 6015-028 and 6015R-028.

Q: Are there any secondary winding configuration differences?

A: No. Both parts have identical secondary winding configuration: dual secondary windings with no center tap, supporting both parallel (14V, 840mA) and series (28V, 420mA) output modes.
