DP-241-4-36 Equivalent & Substitute Parts

Part Overview

The DP-241-4-36 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 (36V, 170mA max output). This chassis-mount transformer is classified as Active product status and is ROHS3 compliant. Equivalent parts are identified when electrical specifications, mechanical mounting requirements, and regulatory compliance align with the original component, enabling direct substitution in applications where the transformer serves as a power conversion interface.

Substitute Part Grouping Explanation

The FD4-36 manufactured by Triad Magnetics qualifies as a direct substitute based on the following electrical and mechanical alignment:

Electrical Equivalence Criteria:

• Identical power rating (6VA)
• Matching primary voltage configuration (115V/230V dual)
• Identical secondary voltage (36V)
• Matching secondary current capacity (170mA)
• Identical isolation voltage specification (2500V)
• Identical core type (Laminated)
• Identical secondary winding configuration (Single with Center Tap)

Mechanical Compatibility Criteria:

• Chassis mount configuration maintained
• Compatible termination styles (Solder, Quick Connect)
• Equivalent weight (0.44 lb)
• Similar physical dimensions within tolerance for chassis mounting

Regulatory Alignment:

• ROHS3 compliance maintained
• Identical ECCN and HTSUS classifications
• REACH Unaffected status consistent

Parameter Comparison

Engineering Selection Recommendations

Both the DP-241-4-36 and FD4-36 maintain Active product status, ensuring continued manufacturer support and availability. Both components satisfy ROHS3 compliance requirements and carry identical regulatory classifications (ECCN: EAR99, HTSUS: 8504.31.4035), making them interchangeable from a compliance perspective.

Physical dimensions show minor variations: the FD4-36 is slightly longer (65.07mm vs. 60.30mm) and narrower (31.75mm vs. 33.30mm), with a marginally lower seated height (34.93mm vs. 36.20mm). These dimensional differences remain within typical chassis mounting tolerances for laminated core transformers in this power class. The termination specification for the FD4-36 explicitly defines quick connect pin size (0.187" / 4.7mm), providing additional clarity for connector compatibility.

Selection between these parts should be based on chassis layout constraints and connector availability. Both components deliver equivalent electrical performance and regulatory compliance.

Frequently Asked Questions (FAQ)

Q: Can the FD4-36 directly replace the DP-241-4-36 in existing designs?

A: Yes. Both transformers share identical electrical specifications (6VA, 115V/230V primary, 36V secondary, 170mA output, 2500V isolation) and mounting type (chassis mount). Minor dimensional differences (approximately 5mm length variation, 1.5mm width variation, 1.3mm height variation) fall within standard chassis mounting tolerances for this transformer class.

Q: Are there any termination compatibility concerns?

A: Both parts support Solder and Quick Connect termination styles. The FD4-36 specifies quick connect pin size as 0.187" (4.7mm). Verify connector compatibility with your specific chassis design before substitution.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both the DP-241-4-36 and FD4-36 are ROHS3 compliant, REACH Unaffected, and carry identical ECCN (EAR99) and HTSUS (8504.31.4035) classifications.

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

A: The center-tapped secondary winding allows the transformer to provide either 36V full voltage or 18V half voltage (center tap to either end), depending on circuit configuration. Both substitute parts maintain this capability.

Q: Are there inventory or lead time considerations?

A: The DP-241-4-36 shows 1055 pieces in stock; the FD4-36 shows 1029 pieces in stock. Both are classified as New Original, indicating current production and availability.
