6027-028 Power Transformer Equivalent and Substitute Parts

Part Overview

The API Delevan Inc. 6027-028 is a laminated core power transformer with a 36VA maximum power rating, designed for through-hole mounting applications. The part features dual primary and secondary windings, providing flexible voltage configurations at 115V or 230V primary input, with corresponding parallel (14V, 2.6A) or series (28V, 1.3A) secondary outputs. As an obsolete product, identification of equivalent substitute parts is necessary for continued system support, maintenance, and new equipment design where legacy compatibility is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution compatibility for the 6027-028 transformer is determined by electrical and mechanical parameters that ensure functional equivalence in end-use applications. The critical parameters governing substitution are:

• Power Rating: 36VA maximum
• Voltage Configuration: Primary (115V, 230V), Secondary (Parallel 14V, Series 28V)
• Current Output: Parallel 2.6A maximum, Series 1.3A maximum
• Winding Configuration: Dual primary and dual secondary windings
• Isolation Voltage: 2500Vrms minimum
• Physical Footprint: 66.68mm L x 55.55mm W x 39.67mm H maximum
• Mounting and Termination: Through-hole mounting with PC pin termination

The 6027R-028 meets all specified electrical and mechanical parameters, with identical power ratings, voltage outputs, current handling, winding configuration, isolation voltage, physical dimensions, and mounting characteristics. The primary distinction is product status and regulatory compliance.

Parameter Comparison

Engineering Selection Recommendations

The 6027R-028 is the primary equivalent substitute for the obsolete 6027-028. Both parts are manufactured by API Delevan Inc. and provide identical electrical performance and mechanical compatibility. The 6027R-028 maintains active product status, ensuring ongoing availability for new designs and maintenance applications.

A significant advantage of the 6027R-028 is ROHS3 compliance, meeting current environmental and regulatory requirements, whereas the original 6027-028 carries non-compliant status. For new equipment designs or system upgrades, the 6027R-028 is the recommended selection. Existing systems currently using the 6027-028 may continue operation without modification; however, future maintenance and replacement should prioritize the 6027R-028 for regulatory alignment and supply chain continuity.

Both parts share identical electrical ratings (36VA, 115V/230V primary, 14V/28V secondary), isolation voltage (2500Vrms), winding configuration (dual primary/secondary), and through-hole PC pin termination. Physical dimensions and weight are unchanged, ensuring direct mechanical substitution in existing circuit board layouts.

Frequently Asked Questions (FAQ)

Q: Can the 6027R-028 replace the 6027-028 in existing applications? A: Yes. The 6027R-028 is electrically and mechanically identical to the 6027-028, with matching voltage ratings, current ratings, power capacity, winding configuration, isolation voltage, physical dimensions, and through-hole mounting characteristics. Direct substitution is possible without circuit or mechanical modifications.

Q: What is the difference between the two part numbers? A: The primary distinction is product lifecycle and regulatory status. The 6027-028 is obsolete and RoHS non-compliant. The 6027R-028 is active production and ROHS3 compliant. Electrical and mechanical specifications are identical.

Q: Which part should be specified for new designs? A: The 6027R-028 should be specified for new equipment designs. It offers active product status and ROHS3 compliance, ensuring regulatory alignment and long-term supply availability.

Q: Are there PCB layout changes required when switching from 6027-028 to 6027R-028? A: No. Both parts have identical physical dimensions (66.68mm L x 55.55mm W x 39.67mm H maximum height), through-hole mounting type, and PC pin termination style. No PCB modifications are necessary.

Q: What are the voltage and current specifications for both parts? A: Both transformers provide a maximum power rating of 36VA with dual primary windings supporting 115V or 230V input, and dual secondary windings providing parallel output of 14V at 2.6A maximum or series output of 28V at 1.3A maximum.

Q: What is the isolation voltage rating? A: Both the 6027-028 and 6027R-028 provide 2500Vrms isolation voltage between primary and secondary windings.
