DP-241-4-16 Equivalent & Substitute Parts

Part Overview

The DP-241-4-16 is a laminated core power transformer manufactured by Signal Transformer, rated at 6VA with dual primary windings (115V/230V) and a single center-tapped secondary winding (16V, 400mA maximum output). This chassis-mounted transformer is classified as Active product status and is fully RoHS3 compliant. Equivalent and substitute parts are identified when they maintain identical electrical specifications and mechanical compatibility within the allowed parameters for this transformer category.

Substitute Part Grouping Explanation

Substitution of the DP-241-4-16 is determined by strict equivalence across the following electrical and mechanical parameters:

• Power Rating: 6VA (exact match required)
• Primary Voltage Configuration: Dual 115V/230V (exact match required)
• Secondary Voltage: 16V (exact match required)
• Output Current Capacity: 400mA minimum (exact match required)
• Secondary Winding Type: Single with center tap (exact match required)
• Core Type: Laminated (exact match required)
• Mounting Configuration: Chassis mount (exact match required)
• Isolation Voltage: 2500V minimum (exact match required)
• Compliance: RoHS3 compliant (required for equivalent status)

The FD4-16 manufactured by Triad Magnetics meets all substitution criteria and is classified as a direct equivalent.

Parameter Comparison

Engineering Selection Recommendations

Both the DP-241-4-16 and FD4-16 are Active product status transformers with identical electrical ratings and RoHS3 compliance. Selection between these parts is based on availability and mechanical fit within the chassis assembly. The FD4-16 specifies quick connect termination at 0.187" (4.7mm), which may require connector compatibility verification in the target application. Both transformers meet the isolation voltage requirement of 2500V and are suitable for equivalent substitution in 6VA, dual primary, center-tapped secondary applications.

Frequently Asked Questions (FAQ)

Q: Can the FD4-16 directly replace the DP-241-4-16 in all applications?

A: The FD4-16 is electrically equivalent across all specified parameters. Mechanical fit must be verified, as the FD4-16 dimensions are 65.07mm L x 31.75mm W x 34.93mm H (max seated), compared to the DP-241-4-16 at 60.30mm L x 33.30mm W x 36.20mm H (max seated). Quick connect termination specifications must be confirmed for connector compatibility.

Q: What are the critical parameters that define substitution for this transformer category?

A: Substitution is strictly defined by: 6VA power rating, dual 115V/230V primary, 16V center-tapped secondary, 400mA output current, laminated core, chassis mount configuration, and 2500V isolation voltage. Any deviation from these parameters disqualifies a part from equivalent status.

Q: Are there compliance considerations when substituting these transformers?

A: Both parts are RoHS3 compliant and REACH unaffected. No compliance barriers exist for substitution between these two transformers.

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

A: The center tap allows the secondary winding to be used as either a single 16V output or as dual 8V outputs referenced to the center point. This configuration must be preserved in any substitute part.
