API Delevan 6055-030 Laminated Power Transformer Equivalent & Substitute Parts

Part Overview

The API Delevan 6055-030 is a laminated core power transformer rated at 48VA with dual primary and secondary windings. The primary accepts 115V or 230V input, while the secondary provides parallel 15V or series 30V output configurations. This through-hole mounted transformer is designed for PC pin termination in industrial and commercial applications.

The 6055-030 carries an obsolete product status. Identifying equivalent substitute parts is necessary to maintain design continuity, ensure supply chain reliability, and support long-term system maintenance where this component is specified in existing installations or legacy designs.

Substitute Part Grouping Explanation

Substitute parts for the 6055-030 are identified based on electrical and mechanical parameter equivalence. The following criteria determine substitution validity:

Electrical Equivalence Requirements:

• Identical power rating (48VA)
• Matching primary voltage inputs (115V, 230V dual configuration)
• Matching secondary voltage outputs (parallel 15V, series 30V)
• Equivalent maximum output current specifications (parallel 3.2A, series 1.6A)
• Identical isolation voltage rating (1500Vrms)
• Matching winding configuration (dual primary, dual secondary, no center tap)

Mechanical Equivalence Requirements:

• Identical core type (laminated)
• Matching mounting type (through hole)
• Matching termination style (PC pin)
• Identical or compatible physical dimensions (47.63mm L × 39.67mm W × 36.50mm H max)
• Equivalent weight specification (1.4 lbs / 635 g)

Parts meeting all electrical and mechanical parameters are classified as direct substitutes and may be used interchangeably in circuit designs and PCB layouts.
