Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the FD6-12 are identified through strict electrical and mechanical parameter matching. The substitution criteria are based on the following key parameters that must remain constant:

• Power Rating: 30VA maximum
• Primary Voltage Configuration: Dual winding supporting both 115V and 230V input
• Secondary Voltage Output: 12.6V at full load
• Secondary Current Capacity: 2.5A maximum
• Secondary Winding Configuration: Single winding with center tap
• Core Type: Laminated construction
• Isolation Voltage: 2500VAC minimum
• Mounting Configuration: Chassis mount
• Termination Compatibility: Solder and Quick Connect terminals (0.187" spacing)
• Regulatory Compliance: RoHS3 compliant, REACH unaffected

The DP-241-6-12 from Signal Transformer meets all specified electrical parameters and mechanical compatibility requirements, making it a direct functional equivalent for the FD6-12.

Parameter Comparison

Engineering Selection Recommendations

The DP-241-6-12 from Signal Transformer is a direct electrical and mechanical equivalent to the FD6-12. Selection between these parts should be based on the following engineering factors:

Regulatory Compliance: Both parts maintain identical RoHS3 compliance and REACH unaffected status, meeting current environmental and hazardous substance restrictions for industrial and commercial applications.

Product Status: Both parts carry Active product status, indicating ongoing manufacturer support and availability through authorized distribution channels.

Mechanical Compatibility: Dimensional variations between the two parts (length 0.05mm, width 1.45mm, height 0.60mm) fall within standard manufacturing tolerances for chassis-mount transformers and do not affect PCB layout or mechanical assembly compatibility.

Electrical Performance: Identical power rating, voltage specifications, current capacity, and isolation voltage ensure functional interchangeability in circuit applications without design modification.

Supply Chain Considerations: The DP-241-6-12 maintains higher inventory availability (1497 units) compared to the FD6-12 (727 units), supporting procurement timelines and production scheduling requirements.

Frequently Asked Questions (FAQ)

Q: Can the DP-241-6-12 be used as a direct replacement for the FD6-12 without circuit modification?

A: Yes. The DP-241-6-12 meets all electrical specifications (30VA, 115V/230V primary, 12.6V secondary, 2.5A output, center-tap configuration) and mechanical requirements (chassis mount, solder/quick-connect termination) of the FD6-12. No circuit design changes are required.

Q: Are there dimensional differences between these parts?

A: Minor dimensional variations exist within manufacturing tolerances: length differs by 0.05mm, width by 1.45mm, and height by 0.60mm. These variations do not affect standard chassis-mount applications or PCB layout compatibility.

Q: Do both parts support the same input voltage options?

A: Yes. Both the FD6-12 and DP-241-6-12 feature dual primary windings supporting 115V and 230V input selection, providing identical operational flexibility.

Q: What is the significance of the center-tap secondary winding?

A: The center-tap configuration on the single secondary winding allows the transformer to provide either 12.6V full output or dual 6.3V outputs referenced to the center tap, supporting applications requiring split-rail power supplies or bridge rectifier configurations.

Q: Are both parts compliant with current environmental regulations?

A: Yes. Both parts are RoHS3 compliant and REACH unaffected, meeting current environmental and hazardous substance restrictions for industrial, commercial, and consumer applications.

Q: What is the isolation voltage specification used for?

A: The 2500VAC isolation voltage specification defines the maximum voltage that can be safely applied between primary and secondary windings without electrical breakdown. Both parts meet this specification, ensuring safe isolation in applications requiring galvanic separation between input and output circuits.

Q: Can these transformers be used in parallel or series configurations?

A: Electrical specifications provided do not include parameters for parallel or series operation. Application-specific requirements should be evaluated against manufacturer datasheets for such configurations.

Q: What termination options are available?

A: Both parts support solder and quick-connect (0.187" spacing) termination styles, providing flexibility for different assembly methods and field service requirements.
