F3480T050 Equivalent & Substitute Parts

Part Overview

The F3480T050 is a three-phase (Delta) EMC/EMI line filter rated for 480VAC at 50A with two-stage configuration and 50/60Hz operation. Manufactured by Curtis Industries, this chassis-mount filter with terminal block termination is designed for general-purpose applications and holds Active product status. Alternative equivalent parts may be required due to inventory constraints, application-specific requirements, or regional availability considerations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the F3480T050 is determined by the following critical parameters:

• Filter Type: Three Phase (Delta) configuration required
• Current Rating: 50A minimum
• Mounting Type: Chassis Mount
• Termination Style: Terminal Block
• Frequency Range: 50/60Hz operation capability
• Voltage Compatibility: Phase-to-phase voltage rating of 480V or higher

The substitute parts listed below meet these core electrical and mechanical requirements. Voltage ratings are evaluated on phase-to-phase basis to ensure compatibility with three-phase delta systems. Configuration differences (single-stage versus two-stage) are noted as they affect filtering characteristics but do not preclude substitution where application requirements permit.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain Active product status and ROHS3 compliance. Selection between F3480T050, 50FCD10, and FN351H-50-33 depends on specific application requirements and regional compliance needs.

F3480T050 (Curtis Industries): Holds CE and UR approvals. Two-stage configuration provides specified filtering performance. Suitable for general-purpose applications requiring both CE and UR certification.

50FCD10 (TE Connectivity Corcom Filters): Holds UR approval. Two-stage configuration matches F3480T050 filtering architecture. Specified for regenerative motor drive applications. Operating temperature range -10°C to 40°C. Suitable where UR certification alone is acceptable and regenerative drive compatibility is required.

FN351H-50-33 (Schaffner EMC Inc.): Holds CSA, ENEC, and UR approvals. Single-stage configuration differs from two-stage design. Voltage rating of 520V exceeds 480V requirement. Frequency range extends to DC operation. Specified for inverters and power drive systems. Operating temperature range -25°C to 100°C. Suitable for applications requiring broader frequency range, extended temperature operation, or CSA/ENEC certification.

Frequently Asked Questions (FAQ)

Q: Can FN351H-50-33 replace F3480T050 in a standard 480VAC application?

A: FN351H-50-33 meets the core electrical requirements: three-phase delta configuration, 50A current rating, 480V phase-to-phase compatibility, 50/60Hz operation, chassis mount, and terminal block termination. However, it features single-stage filtering versus the two-stage design of F3480T050. Application-specific filtering requirements must be evaluated.

Q: What is the significance of the voltage rating difference between 480V and 520V?

A: Both ratings are evaluated on phase-to-phase basis for three-phase systems. The 520V rating of FN351H-50-33 provides margin above the 480V requirement and does not create incompatibility. The 480V rating of 50FCD10 matches the F3480T050 specification exactly.

Q: Are there approval agency differences that affect substitution?

A: F3480T050 carries CE and UR approvals. 50FCD10 carries UR approval only. FN351H-50-33 carries CSA, ENEC, and UR approvals. Selection depends on regional regulatory requirements and end-application certification needs.

Q: How does the single-stage versus two-stage configuration affect substitution?

A: F3480T050 and 50FCD10 both employ two-stage filtering architecture. FN351H-50-33 uses single-stage configuration. This affects EMI/EMC filtering performance characteristics. Application requirements for attenuation levels and frequency response must be evaluated.

Q: What packaging differences exist among these parts?

A: F3480T050 is supplied in Box packaging. 50FCD10 is supplied in Bulk packaging. FN351H-50-33 is supplied in Tray packaging. Packaging does not affect electrical or mechanical compatibility but may influence procurement and handling procedures.

Q: Can these parts be used in regenerative motor drive applications?

A: 50FCD10 is specified for regenerative motor drive applications. FN351H-50-33 is specified for inverters and power drive systems. F3480T050 is specified for general-purpose applications. Application-specific performance requirements must be confirmed with the selected part.
