F1100BB03 Equivalent & Substitute Parts

Part Overview

The F1100BB03 is a single-phase EMC/EMI line filter manufactured by Curtis Industries, rated for 250VAC at 3A with 50/60Hz operation. This chassis-mount filter with wire leads is designed for general-purpose applications requiring electromagnetic compatibility filtering. The part is currently active in production with ROHS3 compliance and CE, CSA, and TUV approvals. Substitute parts are identified when equivalent electrical ratings, mechanical configurations, and approval certifications align with the original specification, enabling component interchangeability in system designs.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the F1100BB03 are qualified based on the following critical parameters:

• Electrical Ratings: Rated AC voltage of 250V and current rating of 3A
• Filter Configuration: Single-phase, single-stage topology
• Mechanical Interface: Chassis-mount with wire lead termination
• Operating Frequency: 50/60Hz operation
• Compliance: ROHS3 compliance and relevant approval certifications (CE, CSA, TUV, UR, VDE, ENEC)
• Application Class: General-purpose EMC/EMI filtering

Three substitute parts meet these criteria: 3VB3 (TE Connectivity Corcom Filters), 851-03/004 (Qualtek), and FN2010-3-07 (Schaffner EMC Inc.). Each maintains the core electrical and mechanical specifications required for direct substitution in 250VAC, 3A single-phase filtering applications.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts maintain active product status and ROHS3 compliance, qualifying them for direct substitution in applications requiring 250VAC, 3A single-phase EMC/EMI filtering with chassis-mount wire-lead configuration.

3VB3 (TE Connectivity Corcom Filters): Holds CSA, UR, and VDE approvals. Operating temperature range of -10°C to 40°C is narrower than the original specification. Inductance of 1.76mH is the lowest among substitutes. Suitable for standard industrial environments within the specified temperature range.

851-03/004 (Qualtek): Holds CSA, UR, and VDE approvals. Dual voltage rating (115V/250VAC) provides operational flexibility beyond the original 250VAC-only specification. Operating temperature range of -25°C to 85°C exceeds typical requirements. Inductance of 2.8mH is the highest among substitutes. Suitable for applications requiring extended temperature performance or dual-voltage capability.

FN2010-3-07 (Schaffner EMC Inc.): Holds CSA, ENEC, and UR approvals. Operating frequency extends to DC and 400Hz, providing broader frequency coverage than the 50/60Hz specification. Operating temperature range of -25°C to 100°C is the widest available. Inductance of 2.5mH is intermediate. Suitable for applications requiring extended frequency or temperature performance.

Frequently Asked Questions (FAQ)

Q: Can the 3VB3 replace the F1100BB03 in all applications? A: The 3VB3 meets the core electrical and mechanical requirements for 250VAC, 3A single-phase filtering. However, its operating temperature range (-10°C to 40°C) is more restrictive than typical industrial specifications. Verify that your application operates within this temperature window before substitution.

Q: What is the advantage of the 851-03/004 over the F1100BB03? A: The 851-03/004 supports both 115V and 250VAC operation, enabling use in dual-voltage systems. Its operating temperature range of -25°C to 85°C accommodates wider environmental conditions. The higher inductance value (2.8mH) may provide enhanced filtering characteristics in specific applications.

Q: Why does the FN2010-3-07 specify DC ~ 400Hz instead of 50/60Hz? A: The FN2010-3-07 is rated for operation across a broader frequency spectrum, from DC to 400Hz. This encompasses 50/60Hz operation and extends to higher frequencies and DC applications. This broader specification does not restrict use in standard 50/60Hz applications.

Q: Are all substitutes ROHS3 compliant? A: Yes. The F1100BB03 and all three substitute parts (3VB3, 851-03/004, FN2010-3-07) are ROHS3 compliant, meeting environmental and hazardous substance restrictions.

Q: Do approval certifications differ between the main part and substitutes? A: Yes. The F1100BB03 carries CE, CSA, and TUV approvals. The 3VB3 and 851-03/004 carry CSA, UR, and VDE approvals. The FN2010-3-07 carries CSA, ENEC, and UR approvals. Verify that the substitute part's certifications align with your system's regulatory requirements before implementation.

Q: What is the significance of inductance values in the parameter comparison? A: Inductance affects the filter's frequency response and attenuation characteristics. The F1100BB03 does not specify inductance. Substitutes range from 1.76mH (3VB3) to 2.8mH (851-03/004). Higher inductance generally provides stronger filtering at lower frequencies. Select based on your EMI/EMC performance requirements.

Q: Can packaging differences affect substitution? A: The F1100BB03 is supplied in bulk packaging, while 851-03/004 and FN2010-3-07 are supplied in tray packaging. The 3VB3 is supplied in bulk. Packaging affects handling and storage but does not impact electrical or mechanical compatibility. Verify packaging availability with your supplier.
