Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 6055-020 is determined by strict electrical and mechanical parameter matching across the following criteria:

Primary Electrical Parameters:

• Power rating: 48VA (exact match required)
• Primary voltage inputs: 115V, 230V (both required)
• Secondary output voltages: Parallel 10V and Series 20V (both configurations required)
• Maximum output currents: Parallel 4.8A and Series 2.4A (exact match required)
• Isolation voltage: 1500Vrms (minimum requirement)

Mechanical and Packaging Parameters:

• Core type: Laminated
• Winding configuration: Dual primary, Dual secondary, no center tap
• Mounting: Through Hole
• Termination: PC Pin
• Physical dimensions: 47.63mm L x 39.67mm W, height up to 36.50mm
• Weight tolerance: 1.4 lbs (635 g)

The 6055R-020 satisfies all substitution criteria with identical electrical specifications and mechanical packaging. The primary distinction is product status: the 6055-020 is Obsolete, while the 6055R-020 is Active with improved compliance certification.

Parameter Comparison

Engineering Selection Recommendations

The 6055R-020 is the qualified substitute for the obsolete 6055-020. Both parts are manufactured by API Delevan Inc. and deliver identical electrical and mechanical specifications, including 48VA power rating, dual primary/secondary winding configuration, and through-hole PC pin termination.

The 6055R-020 offers two significant advantages: Active product status ensures ongoing availability and manufacturing support, and RoHS3 compliance satisfies current environmental and regulatory requirements. The 6055-020, classified as RoHS non-compliant and Obsolete, lacks these certifications and faces discontinuation risk.

For new designs, procurement cycles, or system refreshes, the 6055R-020 is the direct electrical and mechanical equivalent with superior compliance posture. The parts are pin-for-pin and form-fit compatible, requiring no circuit redesign or layout modification for substitution.

Frequently Asked Questions (FAQ)

Q: Are the 6055-020 and 6055R-020 electrically interchangeable? A: Yes. Both transformers provide identical power ratings (48VA), primary voltages (115V/230V), secondary output configurations (Parallel 10V/Series 20V), and isolation voltage (1500Vrms). The electrical specifications match precisely.

Q: Do these transformers have the same physical footprint? A: Yes. Both parts share identical dimensions (47.63mm L x 39.67mm W x 36.50mm H) and weight (1.4 lbs). The through-hole PC pin termination and mounting interface are identical, allowing direct socket substitution.

Q: What is the difference between the 6055-020 and 6055R-020? A: The primary differences are product status and compliance certification. The 6055-020 is Obsolete and RoHS non-compliant, while the 6055R-020 is Active and RoHS3 compliant. No electrical or mechanical differences exist between the two parts.

Q: Why should I use the 6055R-020 instead of the 6055-020? A: The 6055-020 is classified as Obsolete, indicating discontinued manufacturing and limited inventory availability. The 6055R-020 is Active, ensuring stable supply, manufacturing support, and RoHS3 environmental compliance for regulatory adherence.

Q: Can I use the 6055R-020 as a replacement in existing equipment using the 6055-020? A: Yes. The 6055R-020 is a full electrical and mechanical substitute with identical specifications. No circuit modifications, layout changes, or design updates are required for substitution.

Q: Are there any winding or core differences between these transformers? A: No. Both transformers utilize laminated cores with dual primary and dual secondary windings, no center tap configuration, and identical isolation voltage specifications.
