Key Parameters

Substitute Part Grouping Explanation

Substitution of the FN9675-16-03 is determined by the following critical parameters:

Core Compatibility Criteria:

• Single-phase filter configuration
• 16 A current rating
• Minimum 250VAC voltage rating (or dual-voltage 110V/250VAC)
• DC ~ 400Hz operating frequency range
• Chassis-mount form factor
• General-purpose application suitability

Substitute Parts Identified:

The FN2080-16-08 and FN2090-16-06 meet the core electrical and mechanical requirements. Both are active Schaffner EMC Inc. products rated for 16 A with dual-voltage capability (110V/250VAC), maintaining the DC ~ 400Hz frequency range and chassis-mount configuration. The primary differences lie in configuration (two-stage vs. single-stage), termination style (threaded post or quick connect vs. terminal block), and inductance values.

Parameter Comparison

Engineering Selection Recommendations

FN2080-16-08 Selection Criteria: The FN2080-16-08 is an active product with expanded voltage flexibility (110V/250VAC) and additional regulatory approvals (ENEC). The two-stage configuration provides enhanced filtering performance compared to the single-stage FN9675-16-03. Termination via threaded post (M4) requires mechanical redesign of connection points. Lower inductance (2.8mH) may affect filtering characteristics in specific frequency bands. This option is suitable for applications where mechanical redesign is feasible and enhanced filtering is beneficial.

FN2090-16-06 Selection Criteria: The FN2090-16-06 is an active product with the broadest regulatory approval set (CE, CSA, ENEC, UR), supporting both 110V and 250VAC operation. The two-stage configuration matches the FN2080-16-08 in filtering capability. Quick-connect termination enables rapid integration with minimal mechanical modification. Inductance of 4mH provides intermediate filtering characteristics. Operating temperature minimum of -20°C (versus -25°C for the original) may require verification for cold-environment applications. This option is preferred for applications prioritizing ease of integration and comprehensive regulatory compliance.

Frequently Asked Questions (FAQ)

Q: Can FN2080-16-08 or FN2090-16-06 directly replace FN9675-16-03 without modification?

A: Direct replacement depends on termination compatibility. The FN9675-16-03 uses terminal block termination, while FN2080-16-08 uses threaded post (M4) and FN2090-16-06 uses quick connect. Mechanical redesign of connection points is required for either substitute. Electrical compatibility is maintained across all three models for 250VAC, 16 A applications.

Q: What is the impact of configuration change from single-stage to two-stage?

A: Both substitute parts employ two-stage filtering versus the single-stage design of FN9675-16-03. Two-stage configuration provides enhanced EMI/EMC filtering performance across the frequency spectrum. This represents an improvement in filtering capability and does not create compatibility issues for applications designed around the original single-stage filter.

Q: Are there voltage rating differences that affect substitution?

A: The FN9675-16-03 is rated for 250VAC only. Both FN2080-16-08 and FN2090-16-06 support dual-voltage operation (110V/250VAC). For 250VAC applications, both substitutes are fully compatible. The additional 110V capability provides design flexibility for future applications without requiring component changes.

Q: How do inductance differences affect filter performance?

A: The FN9675-16-03 has 10.2mH inductance, while FN2080-16-08 has 2.8mH and FN2090-16-06 has 4mH. Inductance values determine filtering characteristics at specific frequency ranges. Lower inductance in the substitutes may alter attenuation profiles in certain frequency bands. Application-specific filtering requirements should be evaluated against the provided inductance specifications.

Q: What are the regulatory compliance differences?

A: FN9675-16-03 holds CSA and UR approvals. FN2080-16-08 adds ENEC certification. FN2090-16-06 provides the most comprehensive approval set (CE, CSA, ENEC, UR). For applications requiring specific regional certifications, FN2090-16-06 is the most versatile option.

Q: Is there a temperature range consideration for substitution?

A: FN9675-16-03 and FN2080-16-08 both support -25°C ~ 100°C operation. FN2090-16-06 supports -20°C ~ 100°C. For applications requiring operation below -20°C, FN2080-16-08 is the appropriate choice among the substitutes.
