API Delevan 6051-016 Equivalent & Substitute Parts

Part Overview

The API Delevan 6051-016 is a laminated core power transformer rated at 2.5VA with dual primary and secondary windings. This transformer supports dual voltage inputs (115V or 230V) and provides parallel (8V at 312mA) or series (16V at 156mA) output configurations. The part is classified as obsolete, making the identification of active equivalent components essential for ongoing maintenance and new design implementation.

Parameter Comparison

Engineering Selection Recommendations

The 6051R-016 is the recommended substitute for the obsolete 6051-016. Both components share identical electrical performance and mechanical footprints, ensuring direct compatibility in existing designs. The primary distinction between these components is regulatory compliance: the 6051-016 is non-compliant with RoHS3 standards, while the 6051R-016 meets ROHS3 compliance requirements.

For applications subject to RoHS3 regulatory requirements, the 6051R-016 is the appropriate selection. For legacy systems where regulatory compliance is not a constraint, either component provides equivalent functionality. The active production status of the 6051R-016 ensures continued availability and supply chain stability.

Frequently Asked Questions (FAQ)

Q: Can the 6051R-016 directly replace the 6051-016 in existing designs?

A: Yes. The 6051R-016 maintains identical electrical specifications (2.5VA power rating, dual 115V/230V primary inputs, 8V/16V secondary outputs, 312mA/156mA maximum currents) and mechanical characteristics (Through Hole mounting, PC Pin termination, 47.60mm x 39.60mm footprint, 16.50mm height). No circuit modifications or PCB layout changes are required.

Q: What is the primary difference between the 6051-016 and 6051R-016?

A: The 6051R-016 is the active production equivalent of the obsolete 6051-016. The components are electrically and mechanically identical. The 6051R-016 provides ROHS3 compliance, whereas the 6051-016 is RoHS non-compliant. Both maintain REACH Unaffected status and EAR99 ECCN classification.

Q: Are both parts available for procurement?

A: The 6051-016 is obsolete and subject to stock availability limitations. The 6051R-016 is in active production with higher inventory levels, ensuring reliability for current and future procurement.

Q: What are the output current limitations for each voltage configuration?

A: The transformer supports two secondary winding configurations. In parallel configuration, the secondary provides 8V at maximum 312mA. In series configuration, the secondary provides 16V at maximum 156mA. Both the 6051-016 and 6051R-016 support these identical output parameters.

Q: Does the center-tap configuration differ between parts?

A: No. Neither the 6051-016 nor the 6051R-016 includes a center-tap winding. Both utilize dual primary and dual secondary winding configurations without center-tap provisions.
