FN2090B-20-08 Equivalent & Substitute Parts

Part Overview

The FN2090B-20-08 is a single-phase EMC/EMI line filter manufactured by Schaffner EMC Inc., designed for 250VDC/VAC operation at 20A with two-stage filtering configuration. This component is classified as Active product status and is widely used in medical applications requiring electromagnetic compatibility compliance. The need to identify equivalent and substitute parts arises from inventory availability, lead time considerations, packaging requirements, and application-specific voltage or frequency specifications that may differ from the primary part number.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the FN2090B-20-08 is determined by the following critical parameters:

Core Compatibility Criteria:

• Manufacturer: Schaffner EMC Inc. (same manufacturer ensures design consistency)
• Series: FN 2090 (same product family)
• Filter Type: Single Phase (functional category)
• Configuration: Two Stage (filtering architecture)
• Current Rating: 20A (electrical load capacity)
• Inductance: 2.7mH (electromagnetic characteristic)
• Mounting Type: Chassis Mount (mechanical interface)

Application-Dependent Parameters:

• Voltage Rating (DC and AC): Must meet or exceed application requirements
• Frequency Range: Must encompass operating frequency specifications
• Termination Style: May differ based on installation method
• Packaging: May vary (Bulk vs. Tray) without affecting electrical function

The FN2090B-20-06 qualifies as a substitute part because it maintains the same series, filter type, configuration, current rating, inductance, and mounting type. However, differences in voltage rating, frequency range, termination style, and operating temperature range must be evaluated against specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

FN2090B-20-08 Selection Criteria:

• Applications requiring 250VDC operation
• Systems operating exclusively at 50 ~ 60Hz frequency
• Medical device applications requiring UKCA certification
• Installations using threaded post (M4) termination
• Operating environments with minimum temperature requirement of -25°C
• Bulk packaging for high-volume procurement

FN2090B-20-06 Selection Criteria:

• Applications operating at 110VAC or 250VAC (no DC requirement)
• Systems requiring extended frequency range (DC ~ 400Hz)
• General-purpose applications not requiring UKCA certification
• Installations using quick connect termination
• Operating environments with minimum temperature of -20°C
• Tray packaging for standard distribution channels

Both parts maintain ROHS3 compliance, REACH unaffected status, and EAR99 ECCN classification. Selection between these parts depends on voltage specification, frequency range, termination interface, and certification requirements specific to the end application.

Frequently Asked Questions (FAQ)

Q: Can FN2090B-20-06 replace FN2090B-20-08 in a 250VDC medical device application?

A: FN2090B-20-06 does not have a rated DC voltage specification. It is rated for 110V and 250VAC only. For applications requiring 250VDC operation, FN2090B-20-08 is the appropriate selection.

Q: What is the difference in termination style between these two parts?

A: FN2090B-20-08 uses threaded post (M4) termination, requiring screw-based connection. FN2090B-20-06 uses quick connect termination, enabling tool-free installation. The choice depends on the connector interface available in the target application.

Q: Are both parts suitable for medical applications?

A: FN2090B-20-08 is specified for medical applications and includes UKCA certification. FN2090B-20-06 is classified for general-purpose applications and does not include UKCA certification. Medical device applications must use FN2090B-20-08 or verify that FN2090B-20-06 meets specific regulatory requirements.

Q: What is the significance of the frequency range difference?

A: FN2090B-20-08 operates at 50 ~ 60Hz, standard for AC power distribution. FN2090B-20-06 operates from DC ~ 400Hz, supporting variable frequency drives, switched-mode power supplies, and other non-standard frequency applications. Selection depends on the actual operating frequency of the system.

Q: Can packaging type affect electrical performance?

A: No. Packaging type (Bulk vs. Tray) does not affect electrical performance or specifications. Packaging selection is based on procurement volume, storage requirements, and distribution logistics.

Q: What is the operating temperature consideration for substitution?

A: FN2090B-20-08 operates from -25°C to 100°C, while FN2090B-20-06 operates from -20°C to 100°C. For applications requiring operation below -20°C, FN2090B-20-08 is required.
