FD6-16 Equivalent & Substitute Parts Reference

Part Overview

The FD6-16 is a laminated core power transformer manufactured by Triad Magnetics, rated for 30VA maximum power with dual primary windings (115V/230V) and a single center-tapped secondary winding (16V, 2A output). This chassis mount transformer is designed for applications requiring isolated AC power conversion with flexible input voltage selection. The part maintains Active product status with full RoHS3 compliance and REACH unaffected designation. Substitute parts are identified when equivalent electrical specifications, mechanical dimensions, mounting characteristics, and regulatory compliance are maintained within acceptable engineering tolerances.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the FD6-16 is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Requirements:

• Identical power rating (30VA)
• Matching primary voltage configuration (115V/230V dual winding)
• Matching secondary voltage output (16V)
• Matching secondary current capacity (2A minimum)
• Matching isolation voltage rating (2500VAC/Vrms)
• Identical secondary winding configuration (single winding with center tap)

Mechanical & Mounting Equivalence Requirements:

• Chassis mount configuration
• Compatible termination style (Solder and Quick Connect - 0.187")
• Dimensional compatibility within standard manufacturing tolerances
• Equivalent weight classification

Regulatory & Compliance Equivalence:

• RoHS3 compliance status
• REACH unaffected designation
• Matching ECCN and HTSUS classifications

The DP-241-6-16 from Signal Transformer satisfies all substitution criteria through complete parameter alignment.

Parameter Comparison

Engineering Selection Recommendations

Primary Part Selection (FD6-16): The FD6-16 maintains Active product status with 840 units in current inventory. Full RoHS3 compliance and REACH unaffected designation confirm regulatory alignment for EU and international markets. The Quick Pack series designation indicates optimized packaging for standard procurement workflows.

Substitute Part Selection (DP-241-6-16): The DP-241-6-16 is qualified as a direct substitute based on complete electrical and mechanical parameter equivalence. This part carries Active product status with 1195 units in inventory, providing enhanced availability. The Two-4-One™ series designation from Signal Transformer indicates equivalent performance characteristics. RoHS3 compliance and REACH unaffected status match the primary part exactly. Dimensional variations (82.60mm vs 82.55mm length; 44.30mm vs 42.85mm width; 49.80mm vs 49.20mm height) remain within standard manufacturing tolerances for chassis mount applications and do not affect form-fit-function compatibility.

Both parts satisfy identical regulatory classifications (ECCN: EAR99; HTSUS: 8504.31.4035) and carry equivalent compliance certifications.

Frequently Asked Questions (FAQ)

Q: What determines if the DP-241-6-16 can replace the FD6-16?

A: Substitution is valid when all electrical parameters (power rating, voltage levels, current capacity, isolation voltage, winding configuration) and mechanical parameters (mounting type, termination style, dimensions, weight) are equivalent or compatible. The DP-241-6-16 meets all these criteria with identical electrical specifications and compatible mechanical dimensions within standard tolerances.

Q: Are the dimensional differences between FD6-16 and DP-241-6-16 significant?

A: The dimensional variations (length: 0.05mm difference; width: 1.45mm difference; height: 0.60mm difference) are within standard manufacturing tolerances for laminated core transformers and do not affect chassis mount compatibility or electrical performance.

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

A: Yes. Both the FD6-16 and DP-241-6-16 feature dual primary windings supporting 115V and 230V input selection, providing identical flexibility for different regional power supply standards.

Q: Is the center-tap secondary winding identical on both parts?

A: Yes. Both parts feature a single secondary winding with center tap at 16V, enabling identical circuit configurations for center-tapped rectifier applications or balanced output requirements.

Q: What is the significance of the termination style compatibility?

A: Both parts use Solder and Quick Connect - 0.187" (4.7mm) termination, ensuring direct compatibility with existing PCB layouts and connector assemblies without modification.

Q: Are regulatory certifications equivalent between the two parts?

A: Yes. Both parts carry identical RoHS3 compliance status, REACH unaffected designation, ECCN classification (EAR99), and HTSUS code (8504.31.4035), confirming equivalent regulatory standing for procurement and deployment.

Q: Which part should be selected based on availability?

A: Selection should be based on project requirements and supply chain considerations. The DP-241-6-16 currently shows higher inventory (1195 units vs 840 units), which may provide supply chain advantages for high-volume applications.
