Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the FN258P-42-07 is determined by the following critical parameters:

• Filter Type: Three Phase (Delta) configuration
• Configuration: Two Stage topology
• Current Rating: 42 A nominal capacity
• Voltage Ratings: Phase to Ground/Neutral 277 V and Phase to Phase 480 V
• Mounting Type: Chassis Mount
• Termination Style: Terminal Block
• Operating Frequency: DC ~ 60Hz
• Applications: Inverters, Power Drive Systems

The substitute part FN3288-40-33-C35-R65 maintains compatibility through equivalent filter topology, mounting configuration, and termination style. However, the current rating differs (40 A versus 42 A), and voltage ratings are specified differently (530V/305VAC versus 480V/277V). These differences require engineering evaluation based on specific application requirements.

Parameter Comparison

Frequently Asked Questions (FAQ)

Q: What are the primary differences between FN258P-42-07 and FN3288-40-33-C35-R65?

A: The substitute part has a lower current rating (40 A versus 42 A), higher voltage ratings (530V/305VAC versus 480V/277VAC), and an extended lower operating temperature limit (-40°C versus -25°C). The substitute maintains Active product status compared to the end-of-life status of the original part.

Q: Can FN3288-40-33-C35-R65 be used in applications designed for FN258P-42-07?

A: Both parts share identical three-phase (Delta) filter topology, two-stage configuration, chassis mount design, and terminal block termination. Application compatibility depends on whether the voltage and current specifications of the substitute align with system requirements.

Q: Are both parts compliant with industrial standards?

A: Both components are ROHS3 compliant and REACH Unaffected. Both carry CSA, ENEC, and UR approvals (as specified for the main part), supporting use in regulated industrial environments.

Q: What is the packaging format for these components?

A: Both parts are supplied in Tray packaging, suitable for automated assembly and inventory management in production environments.
