Engineering Selection Recommendations

The 6055R-012 is the appropriate substitute for the obsolete 6055-012 based on the following factors:

Product Status: The 6055-012 is classified as obsolete, creating supply chain risk for ongoing production and field repairs. The 6055R-012 maintains active product status with confirmed inventory availability (1070 pieces in stock versus 864 pieces for the obsolete part).

Regulatory Compliance: The 6055R-012 achieves ROHS3 compliance, whereas the 6055-012 is RoHS non-compliant. For applications subject to RoHS directives or customer requirements mandating RoHS compliance, the 6055R-012 is the required selection.

Electrical and Mechanical Equivalence: All electrical parameters (power rating, voltage specifications, current ratings, isolation voltage, winding configuration) and mechanical parameters (core type, mounting, termination, dimensions, weight) are identical between the two parts. This equivalence permits direct substitution without circuit redesign or PCB layout modification.

Supply Chain Continuity: Selection of the 6055R-012 ensures long-term component availability and eliminates the risk of obsolescence-related production delays.

Frequently Asked Questions (FAQ)

Q: Can the 6055R-012 be used as a direct replacement for the 6055-012 in existing designs?

A: Yes. The 6055R-012 is electrically and mechanically identical to the 6055-012. All electrical parameters (48VA power rating, 115V/230V primary, 6.3V/12.6V secondary, 7.6A/3.8A output current, 1500Vrms isolation) and mechanical specifications (laminated core, through-hole mounting, PC pin termination, 47.63mm x 39.67mm x 36.50mm dimensions) are identical. Direct substitution requires no circuit or PCB modifications.

Q: What is the primary difference between the 6055-012 and 6055R-012?

A: The 6055-012 is obsolete with RoHS non-compliant status. The 6055R-012 is an active product with ROHS3 compliance. Electrical and mechanical specifications are identical.

Q: Are there any compatibility concerns when substituting the 6055R-012 for the 6055-012?

A: No compatibility concerns exist. Identical electrical ratings, winding configurations, mounting type, termination style, and physical dimensions ensure full compatibility. The parts are interchangeable at the circuit and PCB levels.

Q: Does the RoHS3 compliance of the 6055R-012 affect its electrical performance compared to the 6055-012?

A: No. RoHS3 compliance relates to material composition and environmental standards, not electrical performance. The 6055R-012 maintains identical electrical specifications to the 6055-012.

Q: What inventory status should be considered when selecting between these parts?

A: The 6055-012 (obsolete) has 864 pieces in stock. The 6055R-012 (active) has 1070 pieces in stock. For new designs and long-term production, the 6055R-012 is the appropriate selection due to active product status and superior supply chain availability.

Q: Are the physical dimensions and mounting footprints identical?

A: Yes. Both parts have identical dimensions of 47.63mm length x 39.67mm width x 36.50mm maximum height, identical through-hole mounting type, and identical PC pin termination. PCB layouts designed for the 6055-012 accommodate the 6055R-012 without modification.
