Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the FN258-180-07 is determined by the following critical parameters:

• Filter Type: Three Phase (Delta) configuration
• Current Rating: 180 A
• Frequency Range: DC ~ 60Hz operation
• Mounting Type: Chassis Mount
• Operating Temperature Range: -25°C ~ 100°C
• Voltage Compatibility: Phase to Ground/Neutral and Phase to Phase ratings

The FN3359-180-28 qualifies as a substitute based on matching filter type, current rating, frequency range, mounting type, and operating temperature. Variations in configuration (three stage versus two stage), termination style (threaded post versus terminal block), and voltage ratings are permissible within the substitution framework when system design accommodates these differences.

Parameter Comparison

Engineering Selection Recommendations

The FN3359-180-28 is the designated substitute for FN258-180-07 applications. Selection of this alternative is supported by:

• Active product status of FN3359-180-28, ensuring continued availability and support
• Identical current rating and frequency operating range
• Matching three-phase delta filter configuration and chassis mount design
• Higher voltage ratings (300 V phase to ground/neutral, 520 V phase to phase) providing operational margin
• Enhanced filtering capability through three-stage configuration versus two-stage design
• Compliance with ROHS3 and REACH requirements

Termination style transition from terminal block to threaded post (M10) requires mechanical integration assessment within the target system. Approval agency differences (CSA, ENEC, UR for FN258-180-07 versus cURus, ENEC for FN3359-180-28) must be evaluated against regional regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can FN3359-180-28 directly replace FN258-180-07 in existing installations?

A: Functional substitution is supported by matching current rating, filter type, and operating frequency. Mechanical integration requires verification of threaded post (M10) compatibility with existing mounting interfaces designed for terminal block termination.

Q: What is the significance of the three-stage versus two-stage configuration difference?

A: Configuration differences reflect filtering topology. The three-stage design of FN3359-180-28 provides additional attenuation stages compared to the two-stage FN258-180-07. Both configurations operate within the same frequency and current parameters.

Q: Are the voltage rating differences critical for substitution?

A: The FN3359-180-28 provides higher voltage ratings (300 V phase to ground/neutral, 520 V phase to phase) compared to FN258-180-07 (277 V, 480 V). Systems operating at or below the original voltage specifications remain compatible with the substitute part.

Q: Why is FN258-180-07 marked as Not For New Designs?

A: This designation indicates the part is in mature or end-of-life status. FN3359-180-28, classified as Active, is the recommended selection for new system designs and ongoing applications.

Q: What packaging format is used for both parts?

A: Both FN258-180-07 and FN3359-180-28 are supplied in Tray packaging for component handling and storage.
