DP-241-6-56 Equivalent & Substitute Parts

Part Overview

The DP-241-6-56 is a laminated core power transformer manufactured by Signal Transformer, rated at 30VA with dual primary windings (115V/230V) and a single secondary winding (56V center-tapped). This chassis-mount transformer is designed for applications requiring isolated AC power conversion with a maximum output current of 540mA. The part is currently active in production and widely available in inventory. Substitute parts may be required due to supply constraints, lead time considerations, or specific packaging preferences while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

The FD6-56 manufactured by Triad Magnetics qualifies as a direct substitute for the DP-241-6-56 based on the following critical parameters:

• Power Rating: Both parts are rated at 30VA
• Primary Voltage Configuration: Both feature dual primary windings supporting 115V and 230V
• Secondary Voltage & Current: Both deliver 56V at 540mA maximum output
• Winding Configuration: Both have single secondary windings with center tap
• Core Type: Both utilize laminated core construction
• Mounting & Termination: Both are chassis-mount with solder and quick-connect termination options
• Isolation Voltage: Both meet 2500V isolation requirements
• Regulatory Compliance: Both are ROHS3 compliant with identical ECCN and HTSUS classifications

Physical dimensions vary slightly (length and width within 0.05mm tolerance; height within 0.6mm), which does not affect functional compatibility in standard chassis-mount applications.

Parameter Comparison

Engineering Selection Recommendations

Both the DP-241-6-56 and FD6-56 are active production parts with full ROHS3 compliance and identical regulatory classifications. Selection between these parts should be based on:

• Availability: The FD6-56 currently has 856 units in stock versus 726 units for the DP-241-6-56
• Packaging: DP-241-6-56 is supplied in bulk packaging; FD6-56 is supplied in box packaging
• Series Designation: DP-241-6-56 belongs to the Two-4-One™ series; FD6-56 belongs to the Quick Pack series
• Mechanical Fit: Verify chassis cutout dimensions accommodate the minor dimensional variations (maximum 1.45mm width difference)

Both parts meet identical electrical specifications and isolation requirements for direct substitution in 30VA, 56V center-tapped transformer applications.

Frequently Asked Questions (FAQ)

Q: Can the FD6-56 replace the DP-241-6-56 in existing designs?

A: Yes. Both transformers meet identical electrical specifications: 30VA power rating, dual 115V/230V primary, 56V center-tapped secondary, 540mA maximum output current, and 2500V isolation. Mechanical dimensions are within acceptable tolerance for standard chassis-mount applications.

Q: What are the key compatibility criteria for these transformers?

A: Substitution is valid when the following parameters match: power rating (30VA), primary voltage configuration (115V/230V dual), secondary voltage (56V), output current capability (540mA), winding configuration (dual primary, single secondary with center tap), core type (laminated), mounting type (chassis mount), and isolation voltage (2500V).

Q: Are there packaging differences between these parts?

A: Yes. The DP-241-6-56 is supplied in bulk packaging, while the FD6-56 is supplied in box packaging. This affects handling and storage but does not impact electrical or mechanical performance.

Q: Do both parts have the same termination options?

A: Both parts feature solder and quick-connect termination. The FD6-56 specifies quick-connect pin size as 0.187" (4.7mm). Verify connector compatibility with your application's mating hardware.

Q: Are there any compliance or regulatory differences?

A: No. Both parts are ROHS3 compliant, REACH unaffected, and share identical ECCN (EAR99) and HTSUS (8504.31.4035) classifications.

Q: What is the maximum dimensional variation between these parts?

A: Length varies by 0.05mm, width by 1.45mm, and height by 0.6mm. These variations are within standard manufacturing tolerances and do not affect functionality in typical chassis-mount applications. Verify your specific mechanical constraints before selection.
