API Delevan 6054-020 Equivalent & Substitute Parts

Part Overview

The API Delevan 6054-020 is a laminated core power transformer rated at 24VA with dual primary and secondary windings. This through-hole mounted component provides selectable output configurations through series and parallel winding connections, delivering either 10V at 2.4A (parallel) or 20V at 1.2A (series) from 115V or 230V primary inputs.

The 6054-020 carries an obsolete product status. Locating equivalent substitute parts is necessary to support legacy system maintenance, repair operations, and continued field deployment where this transformer specification remains functionally required.

Substitute Part Grouping Explanation

Substitute parts for the 6054-020 are identified based on electrical and mechanical parameter equivalence. The following criteria determine substitution validity:

Electrical Equivalence Requirements:

Identical power rating (24VA)
Matching primary voltage inputs (115V, 230V dual selection)
Matching secondary voltage outputs in both parallel (10V) and series (20V) configurations
Matching maximum output current specifications (2.4A parallel, 1.2A series)
Equivalent isolation voltage rating (1500Vrms)

Mechanical Equivalence Requirements:

Identical core type (laminated)
Matching winding configuration (dual primary, dual secondary, no center tap)
Identical mounting type (through hole)
Identical termination style (PC pin)
Compatible physical dimensions (41.28mm L × 33.32mm W × 33.32mm H)

The 6054R-020 meets all electrical and mechanical equivalence criteria and qualifies as a direct substitute for the obsolete 6054-020.

Engineering Selection Recommendations

The 6054R-020 is the direct equivalent substitute for the obsolete 6054-020. Selection between these parts is determined by product availability and compliance requirements:

Use 6054-020 when:

Existing inventory of the original part number is available
Legacy system documentation specifically references this part number
RoHS compliance is not a system requirement

Use 6054R-020 when:

Original 6054-020 inventory is depleted
New production or system updates require active product status
RoHS3 compliance is mandated by system specifications or regulatory requirements
Long-term supply chain continuity is required

Both parts are manufactured by API Delevan Inc. and provide identical electrical performance and mechanical compatibility. The 6054R-020 represents the current production equivalent with improved environmental compliance status.

Frequently Asked Questions (FAQ)

Q: Can the 6054R-020 directly replace the 6054-020 in existing applications?

A: Yes. The 6054R-020 provides complete electrical and mechanical equivalence to the 6054-020. All voltage ratings, current capacities, winding configurations, mounting specifications, and physical dimensions are identical. Direct substitution is supported without circuit modification.

Q: What is the difference between the 6054-020 and 6054R-020?

A: The primary differences are product status and RoHS compliance. The 6054-020 is obsolete and RoHS non-compliant. The 6054R-020 is an active product with ROHS3 compliance. All electrical and mechanical specifications are identical.

Q: Are there any compatibility concerns with PCB mounting?

A: No. Both parts use identical through-hole PC pin termination and share the same physical footprint (41.28mm L × 33.32mm W × 33.32mm H). PCB layouts designed for the 6054-020 accommodate the 6054R-020 without modification.

Q: Does the 6054R-020 support both series and parallel winding configurations?

A: Yes. The 6054R-020 maintains the dual primary and dual secondary winding configuration of the original 6054-020. Both series (20V at 1.2A) and parallel (10V at 2.4A) output modes are supported.

Q: What isolation voltage rating applies to both parts?

A: Both the 6054-020 and 6054R-020 provide 1500Vrms isolation voltage between primary and secondary windings.

Q: Is the 6054R-020 available in the same packaging as the 6054-020?

A: Yes. Both parts use identical through-hole mounting with PC pin termination. No packaging or form factor differences exist between the two parts.
