DP-241-7-56 Equivalent & Substitute Parts

Part Overview

The DP-241-7-56 is a laminated core power transformer manufactured by Signal Transformer, rated at 56VA with dual primary windings (115V/230V) and a single secondary winding (56V, 1A maximum output). This chassis-mounted transformer features a center tap and solder/quick connect termination, designed for applications requiring isolated AC power conversion. The part is active in production and ROHS3 compliant. Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are maintained across the allowed parameter set.

Substitute Part Grouping Explanation

The FD7-56 manufactured by Triad Magnetics qualifies as a direct substitute based on the following matching parameters:

  • Power rating: 56VA (identical)
  • Primary voltage configuration: 115V, 230V dual windings (identical)
  • Secondary voltage: 56V (identical)
  • Secondary current capacity: 1A maximum (identical)
  • Core type: Laminated (identical)
  • Center tap: Present (identical)
  • Mounting type: Chassis mount (identical)
  • Termination style: Solder and quick connect (identical)
  • Isolation voltage: 2500V (identical)
  • RoHS compliance: ROHS3 compliant (identical)

Substitution is valid when all electrical parameters and mechanical mounting requirements remain unchanged in the application circuit.

Engineering Selection Recommendations

Both the DP-241-7-56 and FD7-56 are active production parts with ROHS3 compliance and identical electrical specifications. Selection between these parts should be based on:

  • Availability and lead time requirements
  • Packaging format preference (Bulk versus Box)
  • Mechanical envelope constraints within the application enclosure
  • Termination connector compatibility with existing PCB or wiring harness designs
  • Supply chain and procurement policies

The dimensional variations (length, width, height) are within acceptable tolerance for chassis-mounted transformer applications and do not affect electrical performance or functional compatibility.

Frequently Asked Questions (FAQ)

Q: Can the FD7-56 be used as a direct replacement for the DP-241-7-56 in existing designs?

A: Yes. Both transformers meet identical electrical specifications (56VA, 115V/230V primary, 56V secondary, 1A output, 2500V isolation) and share the same mounting type and termination style. Mechanical dimensions are equivalent within standard tolerances.

Q: Are there any differences in the quick connect termination between these parts?

A: The FD7-56 specifies quick connect termination as 0.187" (4.7mm). Verify that existing connector hardware and PCB footprints accommodate this specification before substitution.

Q: Do both transformers support the same primary voltage configurations?

A: Yes. Both the DP-241-7-56 and FD7-56 feature dual primary windings supporting 115V and 230V operation, with identical center tap functionality.

Q: What is the significance of the packaging difference (Bulk versus Box)?

A: Packaging format does not affect electrical or mechanical performance. The choice between Bulk and Box packaging is a procurement and logistics consideration based on order quantity and handling requirements.

Q: Are both parts compliant with current environmental regulations?

A: Yes. Both the DP-241-7-56 and FD7-56 are ROHS3 compliant and REACH unaffected, meeting current environmental standards for electronic component manufacturing and distribution.
