DP-241-5-56 Equivalent & Substitute Parts

Part Overview

The DP-241-5-56 is a laminated core power transformer manufactured by Signal Transformer, rated at 12VA with dual primary windings (115V/230V) and a single secondary winding (56V center-tapped). This chassis-mount component is designed for applications requiring isolated AC power conversion with a maximum output current of 220mA. The part is Active in product status and widely used in industrial control, audio equipment, and instrumentation applications. Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are maintained across the allowed parameter set.

Substitute Part Grouping Explanation

The FD5-56 manufactured by Triad Magnetics qualifies as a direct substitute for the DP-241-5-56 based on the following critical parameters:

• Power Rating: Both parts are rated at 12VA
• Primary Voltage Configuration: Both support dual primary windings at 115V and 230V
• Secondary Voltage: Both deliver 56V with center-tap configuration
• Output Current: Both support maximum output current of 220mA
• Core Type: Both utilize laminated core construction
• Mounting: Both are chassis-mount configurations
• Termination: Both support Solder and Quick Connect termination styles
• Isolation Voltage: Both meet 2500V isolation requirements
• Regulatory Compliance: Both are ROHS3 compliant with identical ECCN and HTSUS classifications

Dimensional variations (length, width, height) and packaging differences (Bulk vs. Box) do not affect electrical substitution eligibility when mechanical fit is verified in the target application.

Parameter Comparison

Engineering Selection Recommendations

Both the DP-241-5-56 and FD5-56 are Active products with identical electrical specifications and regulatory certifications. Selection between these parts should be based on:

• Mechanical Fit: Verify dimensional compatibility within the target chassis or PCB mounting location. The FD5-56 is marginally smaller in width (34.93mm vs. 36.30mm) and height (41.28mm vs. 42.80mm).
• Termination Connector Compatibility: The FD5-56 specifies 0.187" (4.7mm) quick-connect terminals. Confirm connector pin spacing and gauge compatibility with existing harnesses or solder pads.
• Supply Chain Availability: Both parts maintain active inventory. Current stock levels are 782 Pcs (DP-241-5-56) and 728 Pcs (FD5-56).
• Packaging Requirements: DP-241-5-56 is supplied in Bulk packaging; FD5-56 is supplied in Box packaging. Select based on procurement and handling requirements.

Frequently Asked Questions (FAQ)

Q: Can the FD5-56 directly replace the DP-241-5-56 in an existing design?

A: Yes, provided that mechanical fit is verified. All electrical parameters, isolation voltage, winding configuration, and regulatory compliance are identical. Dimensional differences are minor and should be confirmed against the target application's mounting constraints.

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

A: The FD5-56 specifies 0.187" (4.7mm) quick-connect terminals. Confirm that existing connectors or harnesses are compatible with this pin gauge before substitution.

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

A: Yes. Both the DP-241-5-56 and FD5-56 feature dual primary windings supporting 115V and 230V operation, allowing selection of input voltage at installation.

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

A: The center-tap configuration on the 56V secondary winding allows the transformer to be used in full-wave rectifier circuits or to provide split-rail power supplies (±28V from center tap). Both parts provide this functionality identically.

Q: Are there any compliance or certification differences?

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

Q: What is the maximum output current for these transformers?

A: Both the DP-241-5-56 and FD5-56 support a maximum output current of 220mA at the 56V secondary winding, corresponding to the 12VA power rating.
