FN2412H-45-33 Equivalent & Substitute Parts

Part Overview

The FN2412H-45-33 is a single-phase EMC/EMI line filter manufactured by Schaffner EMC Inc., designed for 45A applications with DIN rail mounting and terminal block termination. This component is classified as obsolete, making identification of equivalent and substitute parts essential for system maintenance and procurement planning. The filter operates across DC to 400Hz frequency range and is approved by CSA, ENEC, and UR agencies. Substitute parts must maintain compatibility with the original electrical specifications, mounting configuration, and regulatory certifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the FN2412H-45-33 is determined by the following critical parameters:

Primary Compatibility Criteria:

• Single-phase filter configuration
• Single-stage topology
• Terminal block termination style
• Operating temperature range: -25°C ~ 100°C
• Regulatory approvals: CSA, ENEC, UR
• RoHS compliance status

Secondary Compatibility Criteria:

• Current rating (45A nominal)
• Frequency operating range (DC ~ 400Hz or compatible subset)
• Mounting type (DIN rail preferred for direct replacement)

The FN2412-45-33 qualifies as a direct equivalent, sharing identical electrical specifications and mounting configuration while maintaining active product status. The FN2410H-60-34 functions as a higher-capacity alternative for applications requiring increased current handling, though it features chassis mount configuration rather than DIN rail mounting.

Parameter Comparison

Engineering Selection Recommendations

FN2412-45-33 (Direct Equivalent): This part is the primary substitute for the obsolete FN2412H-45-33. It maintains identical electrical specifications (45A, DC ~ 400Hz), mounting configuration (DIN rail), and termination style (terminal block). The part holds active product status and carries ROHS3 compliance certification, ensuring long-term availability and regulatory alignment. This substitution requires no design modifications.

FN2410H-60-34 (Higher-Capacity Alternative): This part provides increased current capacity (60A) and extended voltage ratings (520V, 300V AC) while maintaining single-phase, single-stage configuration and terminal block termination. However, the chassis mount configuration differs from the original DIN rail mounting, requiring mechanical redesign of the installation. The operating frequency range (250Hz) is narrower than the original specification (DC ~ 400Hz). This substitution is suitable only when system redesign accommodates the mounting change and when the reduced frequency range meets application requirements.

Frequently Asked Questions (FAQ)

Q: Can FN2412-45-33 be used as a direct replacement for FN2412H-45-33?

A: Yes. Both parts share identical current rating (45A), frequency range (DC ~ 400Hz), mounting type (DIN rail), and termination style (terminal block). The FN2412-45-33 is active product status, making it the recommended substitute for the obsolete FN2412H-45-33.

Q: What are the key differences between FN2412-45-33 and FN2410H-60-34?

A: The FN2410H-60-34 provides higher current capacity (60A versus 45A) and higher voltage ratings (520V, 300V AC). However, it uses chassis mount configuration instead of DIN rail mounting, and operates at a narrower frequency range (250Hz versus DC ~ 400Hz). These differences require mechanical and electrical system evaluation before substitution.

Q: Does mounting type affect substitution compatibility?

A: Yes. The original FN2412H-45-33 uses DIN rail mounting. The FN2412-45-33 maintains this configuration for direct replacement. The FN2410H-60-34 requires chassis mount installation, necessitating mechanical redesign. Mounting type selection depends on system architecture and installation constraints.

Q: Are all substitute parts RoHS compliant?

A: Yes. The FN2412H-45-33 is RoHS Compliant. Both substitute parts (FN2412-45-33 and FN2410H-60-34) carry ROHS3 Compliant certification, ensuring regulatory alignment across all options.

Q: What regulatory approvals apply to these parts?

A: All three parts (FN2412H-45-33, FN2412-45-33, and FN2410H-60-34) hold identical regulatory approvals: CSA, ENEC, and UR. This ensures compliance consistency across substitution options.

Q: Can FN2410H-60-34 be used in applications requiring DC ~ 400Hz operation?

A: No. The FN2410H-60-34 operates at 250Hz maximum frequency, which is narrower than the original DC ~ 400Hz specification. Applications requiring the full frequency range must use FN2412-45-33 or equivalent parts within the FN2412 series.
