DP-241-4-48 Equivalent & Substitute Parts

Part Overview

The DP-241-4-48 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 (48V, 125mA maximum output). This chassis-mount transformer is classified as Active product status and is ROHS3 compliant. Substitute parts are identified when equivalent electrical specifications, mechanical compatibility, and regulatory certifications align with the original design requirements.

Key Parameters

Substitute Part Grouping Explanation

The FD4-48 manufactured by Triad Magnetics qualifies as a direct substitute based on the following electrical and mechanical parameters:

• Identical power rating (6VA)
• Matching primary voltage configuration (115V, 230V dual)
• Matching secondary voltage and current specifications (48V, 125mA)
• Identical core type (Laminated)
• Identical center tap configuration
• Identical mounting type (Chassis Mount)
• Compatible termination style (Solder, Quick Connect)
• Equivalent isolation voltage (2500VAC)
• Matching weight (0.44 lb)
• Identical regulatory compliance (ROHS3, REACH Unaffected, EAR99)

Physical dimensions vary slightly but remain within acceptable tolerance for chassis-mount applications.

Parameter Comparison

Engineering Selection Recommendations

Both the DP-241-4-48 and FD4-48 are Active product status components with identical electrical specifications and regulatory compliance certifications. Selection between these parts is based on availability, packaging format (Bulk vs. Box), and physical dimensions. The FD4-48 features a specified quick-connect terminal size (0.187" / 4.7mm), which may require verification against connector specifications in the target application. Both transformers meet ROHS3, REACH, and EAR99 requirements for equivalent regulatory deployment.

Frequently Asked Questions (FAQ)

Q: Can the FD4-48 replace the DP-241-4-48 in existing designs?

A: Yes. Both transformers share identical electrical specifications (6VA, 115V/230V primary, 48V secondary, 125mA output, center-tapped, 2500V isolation). Physical dimensions differ slightly (DP-241-4-48: 60.30mm L × 33.30mm W × 36.20mm H; FD4-48: 65.07mm L × 31.75mm W × 34.93mm H), requiring verification of chassis cutout and mounting clearance.

Q: Are the termination styles compatible?

A: Both parts support Solder and Quick Connect termination. The FD4-48 specifies 0.187" (4.7mm) quick-connect terminals. Verify connector compatibility with the target application before substitution.

Q: Do both transformers meet the same compliance standards?

A: Yes. Both are ROHS3 compliant, REACH unaffected, and classified as EAR99 under export control regulations. Both share the same HTSUS code (8504.31.4035).

Q: What is the difference between packaging formats?

A: The DP-241-4-48 is supplied in Bulk packaging, while the FD4-48 is supplied in Box packaging. This affects handling, storage, and inventory management but does not impact electrical or mechanical performance.

Q: Are there any dimensional constraints for substitution?

A: Physical dimensions vary within acceptable tolerance for chassis-mount applications. Verify that the FD4-48 dimensions (65.07mm L × 31.75mm W × 34.93mm H) fit within the available mounting space before implementation.
