Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete 6055-040 with the active 6055R-040 is based on electrical and mechanical parameter equivalence. Both transformers maintain identical electrical specifications: 48VA power rating, dual primary windings supporting 115V or 230V input, dual secondary windings with parallel 20V and series 40V output configurations, and matching maximum output currents of 2.4A parallel and 1.2A series. Both employ laminated core construction, through-hole mounting, and PC pin termination with 1500Vrms isolation voltage.

The substitution is valid based on the following key parameters:

• Identical power rating (48VA)
• Identical primary voltage options (115V, 230V)
• Identical secondary voltage configurations (parallel 20V, series 40V)
• Identical output current ratings (2.4A parallel, 1.2A series)
• Identical core type (laminated)
• Identical winding configuration (dual primary, dual secondary)
• Identical mounting and termination (through hole, PC pin)
• Identical isolation voltage (1500Vrms)

Physical dimensions differ between the two parts, with the 6055R-040 featuring a more compact footprint. This dimensional difference does not affect electrical compatibility but requires verification of mechanical fit within the target application's physical constraints.

Parameter Comparison

Engineering Selection Recommendations

The 6055R-040 serves as the direct substitute for the obsolete 6055-040 based on complete electrical parameter equivalence. The primary distinction between these components is product status and regulatory compliance.

The 6055-040 is classified as obsolete, indicating discontinued manufacturing and limited availability. The 6055R-040 maintains active product status with current manufacturing support and documented inventory availability.

From a regulatory perspective, the 6055R-040 achieves ROHS3 compliance, whereas the 6055-040 is RoHS non-compliant. Both parts maintain REACH Unaffected status and share identical ECCN (EAR99) and HTSUS (8504.31.4065) classifications.

The 6055R-040 features a more compact physical footprint with reduced length, width, and height dimensions compared to the 6055-040. This dimensional reduction does not compromise electrical performance and may provide advantages in space-constrained applications. However, mechanical fit verification within the target PCB layout and enclosure is required prior to implementation.

Selection of the 6055R-040 is appropriate for new designs and replacement applications where regulatory compliance and active product support are required. The substitute maintains full electrical compatibility with the original 6055-040 specification.

Frequently Asked Questions (FAQ)

Q: Are the 6055-040 and 6055R-040 electrically interchangeable?

A: Yes. Both transformers provide identical electrical specifications including 48VA power rating, dual primary windings supporting 115V or 230V input, dual secondary windings with parallel 20V and series 40V output, and matching output current ratings of 2.4A parallel and 1.2A series. Isolation voltage, core type, and winding configuration are identical.

Q: What are the physical differences between these parts?

A: The 6055R-040 features a more compact design with reduced dimensions. The 6055-040 measures 47.63mm L × 39.67mm W × 36.50mm H, while the 6055R-040 measures 34.93mm L × 28.58mm W × 23.80mm H. Both parts maintain identical weight at 1.4 lbs (635 g). Mechanical fit verification is required for the target application.

Q: Why is the 6055-040 listed as obsolete?

A: The 6055-040 has been discontinued by the manufacturer. The 6055R-040 represents the active replacement product with ongoing manufacturing support and availability.

Q: Does the 6055R-040 meet current regulatory requirements?

A: Yes. The 6055R-040 is ROHS3 compliant, whereas the 6055-040 is RoHS non-compliant. Both parts maintain REACH Unaffected status. The 6055R-040 is suitable for applications requiring current regulatory compliance.

Q: Can the 6055R-040 be used as a direct replacement in existing designs?

A: Electrical compatibility is confirmed. However, the reduced physical dimensions of the 6055R-040 require verification of mechanical fit within the existing PCB layout and enclosure.
