Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the FN9675-3-06 are identified based on the following critical parameters that determine functional equivalence:

Mandatory Matching Parameters:

• Manufacturer: Schaffner EMC Inc.
• Filter Type: Single Phase
• Current Rating: 3 A
• Mounting Type: Chassis Mount
• Termination Style: Quick Connect
• Operating Frequency: DC ~ 400Hz
• Voltage Compatibility: Must support 250VAC operation

Allowable Variations:

• Configuration: Single-stage to two-stage (two-stage provides enhanced filtering)
• Voltage Range: Extended voltage support (110V/250VAC) is acceptable as it includes the required 250VAC rating
• Inductance: May vary within the filter design while maintaining EMC/EMI performance
• Operating Temperature: May have different ranges provided minimum and maximum bounds encompass or match the original
• Product Status: Active products are preferred over obsolete classifications
• RoHS Compliance: Evolution from RoHS to ROHS3 represents regulatory progression

The substitute parts FN2080-3-06 and FN2090-3-06 meet all mandatory matching parameters and represent active alternatives with enhanced two-stage filtering configurations.

Parameter Comparison

Engineering Selection Recommendations

FN2080-3-06 is suitable for applications requiring 250VAC operation with identical temperature range (-25°C ~ 100°C) to the original FN9675-3-06. This part offers active product status with CSA, ENEC, and UR certifications. The two-stage configuration provides enhanced EMC/EMI filtering performance compared to the single-stage original design. ROHS3 compliance represents current regulatory alignment.

FN2090-3-06 is suitable for applications requiring 250VAC operation with a slightly reduced minimum operating temperature (-20°C vs. -25°C). This part offers active product status with the broadest certification scope: CE, CSA, ENEC, and UR approvals. The two-stage configuration provides enhanced EMC/EMI filtering performance. ROHS3 compliance represents current regulatory alignment.

Both substitute parts maintain the same 3A current rating, quick-connect termination, chassis-mount configuration, and DC to 400Hz frequency range as the original FN9675-3-06. Selection between FN2080-3-06 and FN2090-3-06 depends on specific application requirements regarding minimum operating temperature and required regulatory certifications.

Frequently Asked Questions (FAQ)

Q: Can FN2080-3-06 or FN2090-3-06 directly replace FN9675-3-06 in existing designs?

A: Yes. Both substitute parts maintain identical current rating (3A), voltage support for 250VAC, mounting type (chassis mount), termination style (quick connect), and operating frequency range (DC ~ 400Hz). The two-stage configuration in the substitutes provides equivalent or enhanced EMC/EMI filtering performance.

Q: What is the difference between single-stage and two-stage filter configurations?

A: Configuration refers to the internal filtering network architecture. Both single-stage and two-stage designs operate within the same electrical parameters specified for this product category. Two-stage designs typically provide additional filtering stages for enhanced EMC/EMI performance.

Q: Why do the substitute parts support both 110V and 250VAC?

A: FN2080-3-06 and FN2090-3-06 are rated for dual-voltage operation (110V and 250VAC). This extended voltage range includes the 250VAC requirement of the original FN9675-3-06, making these parts functionally compatible for 250VAC applications.

Q: Are there differences in inductance values between these parts?

A: Yes. FN9675-3-06 specifies 18mH, FN2080-3-06 specifies 9.8mH, and FN2090-3-06 specifies 14mH. These variations reflect different internal filter designs while maintaining compliance with the same electrical performance category and operating parameters.

Q: What is the significance of the operating temperature range difference?

A: FN9675-3-06 and FN2080-3-06 both operate from -25°C to 100°C. FN2090-3-06 operates from -20°C to 100°C. For applications requiring operation below -20°C, FN2080-3-06 is the appropriate substitute. For applications operating at -20°C or above, both FN2080-3-06 and FN2090-3-06 are suitable.

Q: What certifications should I verify for my application?

A: FN2080-3-06 holds CSA, ENEC, and UR certifications. FN2090-3-06 holds CE, CSA, ENEC, and UR certifications. Verify that the required certifications for your specific application and market are present on the selected substitute part.

Q: Does packaging differ between these parts?

A: FN9675-3-06 is packaged with a dash designation. FN2080-3-06 and FN2090-3-06 are packaged in trays. Confirm packaging requirements for your procurement and assembly processes.
