Key Parameters

Substitute Part Grouping Explanation

Substitution is determined by matching the following electrical and mechanical parameters:

• Filter Type (Three Phase, Delta)
• Rated Voltage (Phase to Ground/Neutral and Phase to Phase)
• Rated Current
• Frequency Range (DC ~ 60Hz)
• Configuration (Stage count)
• Mounting Type (Chassis Mount)
• Termination Style
• Compliance with RoHS and REACH

Only parts with explicitly provided parameters falling within or exceeding those of the original model are considered as valid substitutes. Product status and official certifications are also strictly adhered to in evaluation.

Parameter Comparison

Engineering Selection Recommendations

FN351-280-37 is classified as obsolete. The substitute part FN3359-320-99 is listed as active and meets RoHS3 compliance and REACH unaffected status. Selection must be based solely on electrical and mechanical parameters provided, including rated current, voltage, filter configuration, mounting type, and termination style, in addition to official certifications and product status.

Frequently Asked Questions (FAQ)

Q1: What substitution criteria are used for EMC/EMI line filters?
Substitutes are selected based on filter type, rated voltage, rated current, frequency range, configuration, mounting method, termination style, and regulatory compliance.

Q2: Are package and configuration differences considered?
Only provided mechanical mounting type and termination details are compared. Substitution is valid when these explicit parameters are compatible.

Q3: How does compliance status affect substitute selection?
Direct component substitution requires matching RoHS and REACH statuses as provided.

Q4: Is the substitute part FN3359-320-99 compatible by current and voltage?
FN3359-320-99 exceeds the original's rated current and voltage, meeting substitution requirements for these parameters.

Q5: Can discontinued parts be directly replaced?
Obsolete status necessitates substitution with active parts that meet all specified selection criteria within the same product category.
