This compliance upgrade is significant for applications subject to RoHS directives in the European Union and equivalent regulatory frameworks.

Compatibility Assurance: Identical voltage configurations, current ratings, isolation specifications, and physical form factor guarantee functional and mechanical interchangeability. No circuit modifications, PCB redesign, or application firmware changes are required for substitution.

Regulatory and Supply Chain Considerations: Selection of the 6051R-230 eliminates obsolescence risk and ensures long-term component availability. The active product status provides access to current manufacturing batches, quality certifications, and technical support from API Delevan Inc.

Frequently Asked Questions (FAQ)

Q: Can the 6051R-230 be used as a direct replacement for the 6051-230 without any modifications?

A: Yes. The 6051R-230 is electrically and mechanically identical to the 6051-230. All voltage ratings, current capacities, winding configurations, isolation specifications, and physical dimensions match exactly. No circuit changes or PCB modifications are necessary.

Q: What is the primary difference between the 6051-230 and 6051R-230?

A: The 6051R-230 is the active production equivalent of the obsolete 6051-230. Both components are manufactured by API Delevan Inc. and share identical electrical and mechanical specifications. The 6051R-230 is RoHS3 compliant, while the 6051-230 is not. The 6051R-230 has current manufacturing support and availability.

Q: Are the physical dimensions and mounting footprints identical?

A: Yes. Both the 6051-230 and 6051R-230 have identical dimensions of 47.60mm length × 39.60mm width × 16.50mm maximum height. Both use through-hole PC pin termination and are designed for the same PCB mounting pattern.

Q: Does the 6051R-230 support the same voltage and current configurations?

A: Yes. The 6051R-230 provides identical dual primary and secondary winding configurations. Primary voltage selection is 115V or 230V. Secondary output is 115V (parallel connection) or 230V (series connection). Maximum output currents are 20mA (parallel) and 10mA (series), matching the 6051-230 specifications exactly.
