Key Parameters

Substitute Part Grouping Explanation

Substitution of the FN510-33-33 is determined by the following critical parameters:

• Filter Type: Three Phase (Delta) configuration
• Mounting Type: Chassis Mount with Terminal Block termination
• Current Rating: Minimum 33 A capacity
• Voltage Ratings: Phase to Ground/Neutral and Phase to Phase compatibility
• Regulatory Compliance: RoHS and REACH status alignment

The FN5060-45-99 qualifies as a substitute based on matching filter type, mounting configuration, and termination style. The substitute maintains three-phase (Delta) filtering architecture with chassis mount installation and terminal block connection. Current rating of 45 A exceeds the 33 A requirement, providing operational margin. Voltage ratings of the substitute (500 V Phase to Ground/Neutral, 550 V Phase to Phase) accommodate the original specification envelope.

Parameter Comparison

Engineering Selection Recommendations

The FN5060-45-99 is an active product from the same manufacturer, eliminating obsolescence concerns associated with the FN510-33-33. Both components maintain REACH Unaffected status, ensuring regulatory alignment. The substitute operates across an extended temperature range (-25°C ~ 100°C versus -25°C ~ 70°C), providing enhanced thermal performance margin. Current capacity of 45 A exceeds the original 33 A specification, supporting higher load conditions without derating. Voltage ratings of the substitute accommodate the original system requirements with additional headroom. Chassis mount configuration and terminal block termination remain consistent, preserving mechanical and electrical interface compatibility.

Frequently Asked Questions (FAQ)

Q: Can the FN5060-45-99 directly replace the FN510-33-33 in existing installations?

A: Yes. Both components share identical filter type (three-phase Delta), mounting configuration (chassis mount), and termination style (terminal block). The substitute's higher current rating (45 A) and voltage ratings (500 V phase to ground/neutral, 550 V phase to phase) are compatible with the original specification.

Q: What is the significance of the current rating difference between 33 A and 45 A?

A: The 45 A rating of the substitute exceeds the original 33 A requirement. This provides operational margin and supports higher load conditions without component derating. No derating is required when substituting a higher-rated filter in a 33 A application.

Q: How do the operating temperature ranges differ?

A: The FN510-33-33 operates from -25°C to 70°C, while the FN5060-45-99 extends to 100°C. The substitute provides enhanced thermal performance capability, beneficial for applications in elevated ambient conditions.

Q: Are there packaging differences between these components?

A: The FN510-33-33 packaging is not specified in the available data. The FN5060-45-99 is supplied in Tray packaging. Verify packaging requirements for your procurement and handling procedures.

Q: What is the inductance specification of the substitute?

A: The FN5060-45-99 has an inductance rating of 170µH. The original FN510-33-33 inductance value is not provided in the available technical data.

Q: Are both components compliant with current regulatory standards?

A: Both components maintain REACH Unaffected status. The FN510-33-33 is ROHS3 Compliant. The FN5060-45-99 RoHS status is not specified in the available data. Verify compliance requirements for your specific application and region.
