DP-241-4-56 Equivalent & Substitute Parts

Part Overview

The DP-241-4-56 is a laminated core power transformer manufactured by Signal Transformer, rated at 6VA 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 110mA. The part is currently active in production and widely available in inventory. Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are required due to supply constraints, design flexibility, or application-specific packaging preferences.

Key Parameters

Substitute Part Grouping Explanation

The FD4-56 manufactured by Triad Magnetics qualifies as a direct substitute based on the following critical parameters:

• Identical power rating (6VA)
• Matching primary voltage configuration (115V/230V dual)
• Identical secondary voltage and center-tap configuration (56V with center tap)
• Equivalent maximum output current (110mA)
• Identical core type (laminated)
• Identical mounting type (chassis mount)
• Compatible termination styles (both include solder and quick connect options)
• Equivalent isolation voltage rating (2500V)
• Matching RoHS3 compliance and regulatory status

Dimensional variations exist between the two parts, requiring verification of available mounting space in the target application. Both parts maintain identical electrical performance specifications and regulatory compliance.

Parameter Comparison

Engineering Selection Recommendations

Both the DP-241-4-56 and FD4-56 are active production parts with full ROHS3 compliance and equivalent regulatory certifications (REACH Unaffected, ECCN EAR99). Selection between these parts should be based on:

1. Mounting Space Availability: The FD4-56 is 4.77mm longer and 1.55mm narrower, with a height 1.27mm lower than the DP-241-4-56. Verify dimensional compatibility within the target chassis or PCB layout.

2. Connector Compatibility: The FD4-56 specifies quick connect terminals at 0.187" (4.7mm), while the DP-241-4-56 lists quick connect without specific dimension. Confirm connector pin spacing matches existing harnesses or solder pads.

3. Inventory and Lead Time: Both parts maintain active inventory status. Selection may depend on supplier availability and delivery requirements.

4. Series Preference: The DP-241-4-56 belongs to the Two-4-One™ series, while the FD4-56 is part of the Quick Pack series. No functional difference exists; series designation reflects manufacturer product line organization.

Frequently Asked Questions (FAQ)

Q: Can the FD4-56 directly replace the DP-241-4-56 in an existing design?

A: Electrical substitution is valid. The FD4-56 provides identical voltage, current, power rating, and isolation specifications. Physical substitution requires verification of mounting dimensions and connector compatibility within the available space.

Q: What are the key differences between these two transformers?

A: The transformers are electrically identical. Differences are limited to physical dimensions (length, width, height) and packaging series designation. Both maintain identical electrical performance and regulatory compliance.

Q: Are the quick connect terminals compatible between the two parts?

A: Both parts include solder and quick connect termination options. The FD4-56 specifies 0.187" (4.7mm) quick connect terminals. Confirm terminal spacing and pin configuration match the target application before substitution.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both the DP-241-4-56 and FD4-56 are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with identical HTSUS codes (8504.31.4035).

Q: Which part should be selected for new designs?

A: Both parts are active and suitable for new designs. Selection should be based on supplier availability, lead time, and physical space constraints within the target application. No technical advantage exists between the two options.
