Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the FN2410H-45-33 is determined by the following critical parameters:

Primary Substitution Criteria:

• Series: FN 2410 (same product family)
• Filter Type: Single Phase
• Configuration: Single Stage
• Mounting Type: Chassis Mount
• Termination Style: Terminal Block
• Operating Temperature Range: -25°C ~ 100°C
• Approval Agencies: CSA, ENEC, UR

Electrical Compatibility Parameters:

• Voltage Rating: 520V/300VAC (must support both voltage levels)
• Current Rating: 45 A minimum
• Frequency Range: DC ~ 400Hz minimum

Two substitute parts meet these criteria and are classified as active products within the FN 2410 series.

Parameter Comparison

Engineering Selection Recommendations

FN2410-45-33: This substitute maintains identical current rating (45 A) and frequency range (DC ~ 400Hz) as the main part. However, the voltage rating is limited to 250VAC, which does not support the 520V/300VAC requirement of the FN2410H-45-33. This part is suitable only for applications operating at 250VAC. Product status is active with ROHS3 compliance.

FN2410H-60-34: This substitute supports the same dual voltage rating (520V/300VAC) and maintains all mechanical and thermal specifications. The current rating is increased to 60 A, providing headroom above the 45 A requirement. The operating frequency is specified as 250Hz, which is narrower than the DC ~ 400Hz range of the main part. Product status is active with ROHS3 compliance and full certification alignment (CSA, ENEC, UR).

For direct functional replacement of the FN2410H-45-33 in 520V/300VAC applications, the FN2410H-60-34 is the appropriate selection. The FN2410-45-33 is limited to 250VAC systems only.

Frequently Asked Questions (FAQ)

Q: Can FN2410-45-33 replace FN2410H-45-33 in all applications?

A: No. The FN2410-45-33 is rated for 250VAC only, while the FN2410H-45-33 operates at 520V/300VAC. Substitution is valid only for applications using 250VAC supply voltage.

Q: What is the difference between FN2410H-60-34 and FN2410H-45-33?

A: The FN2410H-60-34 has a higher current rating (60 A vs. 45 A) and a narrower frequency range (250Hz vs. DC ~ 400Hz). Both support 520V/300VAC operation. The increased current capacity provides margin for the same or higher load applications.

Q: Are all three parts mechanically compatible?

A: Yes. All three parts share identical mounting type (chassis mount), termination style (terminal block), and operating temperature range (-25°C ~ 100°C), ensuring mechanical interchangeability in the same installation footprint.

Q: What is the product status significance?

A: The FN2410H-45-33 is obsolete, meaning it is no longer manufactured. The FN2410-45-33 and FN2410H-60-34 are active products with current manufacturing and availability.

Q: Do all parts meet the same compliance standards?

A: Yes. All three parts carry CSA, ENEC, and UR approvals. The main part is RoHS Compliant, while both substitutes are ROHS3 Compliant, representing an updated compliance standard.

Q: Which substitute should be selected for a 520V/300VAC application?

A: The FN2410H-60-34 is the appropriate selection, as it maintains the required dual voltage rating and all mechanical specifications of the original part.
