FX0417 Equivalent & Substitute Parts

Part Overview

The FX0417 is a cartridge fuse holder manufactured by Bulgin, rated for 20 A at 250V with panel mount configuration. This component is designed for single-circuit applications using 3AG cartridge fuses (0.25" Dia x 1.26" L). The product is currently obsolete, making identification of compatible substitute parts essential for ongoing maintenance, repair, and design continuity in legacy systems.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the FX0417 is determined by the following critical parameters:

• Voltage Rating: Must be 250V (exact match required)
• Fuse Size: Must accommodate 3AG cartridge fuses (0.25" Dia x 1.26" L / 6.35mm x 32mm)
• Number of Circuits: Must be single-circuit (1 circuit)
• Mounting Type: Must be panel mount
• Fuse Type: Must be cartridge type

The D0347RA meets these core substitution criteria. However, differences exist in current rating (16 A vs. 20 A), termination style (Quick Connect vs. Solder Lug), and orientation (Right Angle vs. standard), which must be evaluated against specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

The D0347RA is the manufacturer-recommended substitute for the FX0417. Both components are ROHS3 compliant and manufactured by Bulgin, ensuring regulatory consistency.

Current Rating Consideration: The D0347RA is rated for 16 A, compared to the FX0417's 20 A rating. This lower current rating must be evaluated against the actual circuit requirements. If the application circuit operates at or below 16 A, the D0347RA is suitable. If sustained operation above 16 A is required, alternative solutions must be explored.

Termination and Orientation Differences: The D0347RA uses Quick Connect termination and Right Angle orientation, whereas the FX0417 uses Solder Lug termination with standard orientation. These differences require mechanical and electrical integration assessment for the specific application.

Product Status: The active status of D0347RA ensures ongoing availability and supply chain continuity compared to the obsolete FX0417.

Frequently Asked Questions (FAQ)

Q: Can the D0347RA directly replace the FX0417 in all applications?

A: Direct replacement depends on application-specific requirements. Both components share identical voltage (250V), fuse size (3AG cartridge), and circuit configuration (single-circuit panel mount). However, the lower current rating (16 A vs. 20 A) and different termination style (Quick Connect vs. Solder Lug) must be verified against circuit specifications and PCB design.

Q: What is the significance of the current rating difference between FX0417 (20 A) and D0347RA (16 A)?

A: Current rating indicates the maximum continuous current the fuse holder is designed to safely conduct. If your circuit operates at 16 A or below, the D0347RA is suitable. If sustained operation above 16 A is required, the lower rating of D0347RA may not meet application demands.

Q: Does the Right Angle orientation of D0347RA affect compatibility?

A: Orientation affects physical mounting and space requirements on the PCB or panel. Right Angle configuration differs from standard orientation, requiring verification that the component fits within available space and maintains proper clearances for fuse insertion and removal.

Q: Are both components RoHS compliant?

A: Yes, both FX0417 and D0347RA are ROHS3 compliant, ensuring regulatory alignment for applications subject to RoHS requirements.

Q: What is the difference between Solder Lug and Quick Connect termination?

A: Solder Lug termination requires soldering to PCB pads or wire connections. Quick Connect termination uses push-on or snap-fit connectors for faster assembly and potential field replacement. The choice depends on assembly process and maintenance requirements.
