Substitute Part Grouping Explanation
Substitution eligibility for the FN258L-30-07 is determined by the following critical parameters:
- Filter Type: Three Phase (Delta) configuration
- Configuration: Two Stage topology
- Mounting Type: Chassis Mount
- Termination Style: Terminal Block
- Frequency Range: DC ~ 60Hz operation
- Applications: Inverters, Power Drive Systems
The FN3288-25-33-C35-R65 qualifies as a substitute based on matching filter type, configuration, mounting, termination, and application compatibility. However, the current rating differs (25 A versus 30 A), and voltage specifications vary. Substitution is valid only when the system's actual current demand does not exceed 25 A and the voltage requirements align with the substitute's ratings.

Engineering Selection Recommendations
The FN3288-25-33-C35-R65 is the active substitute for the FN258L-30-07. Key considerations for selection:
Current Rating: The substitute is rated for 25 A, which is 5 A lower than the original 30 A rating. Selection is appropriate only when the system's maximum operating current does not exceed 25 A.
Voltage Compatibility: The substitute operates at higher voltage ratings (305 V phase-to-ground, 530 V phase-to-phase) compared to the original (277 V, 480 V). Verify that the system voltage specifications align with the substitute's ratings before implementation.
Product Status: The substitute carries Active status, ensuring continued availability and support. The original part is classified as Not For New Designs, making the substitute the recommended choice for ongoing system maintenance and repair.
Compliance: Both parts maintain ROHS3 compliance and are rated for the same applications (Inverters, Power Drive Systems). The substitute offers an extended operating temperature range (-40°C ~ 100°C versus -25°C ~ 100°C), providing additional thermal margin.
Frequently Asked Questions (FAQ)
Q: Can the FN3288-25-33-C35-R65 directly replace the FN258L-30-07 in all applications?
A: Direct replacement is valid only when the system's maximum current demand does not exceed 25 A and the voltage specifications match the substitute's ratings (305 V phase-to-ground, 530 V phase-to-phase). Current and voltage compatibility must be verified before substitution.
Q: What is the significance of the "Not For New Designs" status on the FN258L-30-07?
A: This status indicates the part has reached end-of-life and is no longer recommended for new product development. The FN3288-25-33-C35-R65, with Active status, is the supported alternative for ongoing applications.
Q: Are both parts compatible with the same mounting and termination configurations?
A: Yes. Both parts feature chassis mount configuration with terminal block termination, ensuring mechanical and electrical interface compatibility.
Q: What is the difference in operating temperature ranges between the two parts?
A: The FN258L-30-07 operates from -25°C to 100°C, while the FN3288-25-33-C35-R65 operates from -40°C to 100°C. The substitute provides a 15°C lower temperature limit, offering enhanced performance in cold environments.
Q: Do both parts meet the same regulatory approvals?
A: Both parts are ROHS3 compliant and REACH unaffected. The FN258L-30-07 carries CSA, ENEC, and UR approvals. Verify that the substitute's certifications meet your specific regulatory requirements for your application region.
Q: What packaging format is used for both parts?
A: Both parts are supplied in Tray packaging, suitable for automated assembly and component handling.
