F1100AA03 Single Phase EMC/EMI Line Filter Equivalent & Substitute Parts

Part Overview

The F1100AA03 is a single phase EMC/EMI line filter manufactured by Curtis Industries, rated for 250VAC at 3A with 50/60Hz operation. This chassis-mounted filter features quick connect termination and is designed for general purpose applications requiring electromagnetic compatibility filtering. The part is currently active in production with 1149 units in stock. Equivalent and substitute parts are identified when they share identical electrical specifications (voltage, current, frequency) and mechanical compatibility (chassis mount, quick connect termination) while maintaining active product status and equivalent compliance certifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the F1100AA03 are qualified based on the following electrical and mechanical parameters:

Primary Substitution Criteria:

• Filter Type: Single Phase
• Configuration: Single Stage
• Voltage Rating: 250VAC (minimum requirement)
• Current Rating: 3A (exact match)
• Frequency: 50/60Hz operation capability
• Mounting: Chassis Mount
• Termination: Quick Connect
• Product Status: Active

Qualified Substitutes: All three substitute parts (3VB1, 851-03/003, FN2010-3-06) meet these core electrical and mechanical requirements. The 851-03/003 additionally supports 115VAC operation, providing broader voltage flexibility. Frequency operating ranges vary: the F1100AA03 and 3VB1 operate at 50/60Hz, while FN2010-3-06 extends to DC ~ 400Hz, and 851-03/003 maintains 50/60Hz operation.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts are qualified for direct replacement of the F1100AA03 based on matching electrical specifications and mechanical compatibility. Selection among these options should consider:

Compliance Certifications:

• F1100AA03: CE, CSA, TUV
• 3VB1: CSA, UR, VDE
• 851-03/003: CSA, UR, VDE
• FN2010-3-06: CSA, ENEC, UR

Operational Frequency Range: The FN2010-3-06 supports DC ~ 400Hz operation, providing the broadest frequency compatibility compared to the standard 50/60Hz specification of the F1100AA03, 3VB1, and 851-03/003.

Voltage Flexibility: The 851-03/003 supports both 115VAC and 250VAC operation, offering dual-voltage capability not present in other options.

Inventory Availability: FN2010-3-06: 1995 units; 851-03/003: 1241 units; 3VB1: 924 units; F1100AA03: 1149 units.

Frequently Asked Questions (FAQ)

Q: Can the 3VB1 directly replace the F1100AA03? A: Yes. Both parts share identical electrical ratings (250VAC, 3A, 50/60Hz), single phase single stage configuration, chassis mount design, and quick connect termination. Both are ROHS3 compliant and active products.

Q: What is the advantage of using the 851-03/003 over the F1100AA03? A: The 851-03/003 supports dual voltage operation (115VAC and 250VAC) while maintaining the same 3A current rating and 50/60Hz frequency. This provides flexibility for applications requiring either voltage level. It is supplied in tray packaging rather than bulk.

Q: Why does the FN2010-3-06 have a wider frequency range? A: The FN2010-3-06 is specified for DC ~ 400Hz operation, compared to the standard 50/60Hz of the F1100AA03. This extended frequency range makes it suitable for applications with variable frequency drives or DC power supplies, while remaining compatible with standard 50/60Hz mains operation.

Q: Are there differences in operating temperature ranges? A: Yes. The F1100AA03 does not specify an operating temperature range. The 3VB1 operates from -10°C to 40°C, the 851-03/003 from -25°C to 85°C, and the FN2010-3-06 from -25°C to 100°C. Application environment requirements should guide selection if temperature extremes are present.

Q: What packaging options are available? A: The F1100AA03 and 3VB1 are supplied in bulk packaging. The 851-03/003 and FN2010-3-06 are supplied in tray packaging. Packaging selection may affect procurement quantities and handling procedures.

Q: Do all substitute parts meet the same compliance standards? A: All parts are ROHS3 compliant and carry CSA certification. The F1100AA03 includes CE and TUV; the 3VB1 includes UR and VDE; the 851-03/003 includes UR and VDE; the FN2010-3-06 includes ENEC and UR. Application-specific compliance requirements should determine the appropriate selection.
