Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the FN2010B-20-08 is determined by strict equivalence in the following parameters:

• Voltage - Rated AC: 250V (exact match required)
• Current: 20 A (exact match required)
• Filter Type: Single Phase (exact match required)
• Configuration: Single Stage (exact match required)
• Mounting Type: Chassis Mount (exact match required)
• RoHS Status: ROHS3 Compliant (compliance requirement)
• Product Status: Active (availability requirement)

The F1199AA20 from Curtis Industries meets all mandatory electrical and mechanical criteria. Variations in frequency operating range, termination style, and inductance specifications do not preclude substitution when the core filtering parameters remain equivalent.

Parameter Comparison

Engineering Selection Recommendations

Both the FN2010B-20-08 and F1199AA20 are active products with ROHS3 compliance and REACH unaffected status. Selection between these parts should be based on:

• Termination interface requirements: The FN2010B-20-08 uses threaded post (M4) termination, while the F1199AA20 uses quick connect termination. System design must accommodate the selected termination style.
• Frequency operating range: The FN2010B-20-08 operates across DC ~ 400Hz, providing broader frequency coverage than the F1199AA20 (50/60Hz). Applications requiring extended frequency range must use the FN2010B-20-08.
• Regulatory certifications: The F1199AA20 includes CE and TUV certifications in addition to CSA and UR, providing additional compliance documentation for certain markets.
• Inventory availability: The F1199AA20 has higher stock levels (1226 units versus 743 units).

Frequently Asked Questions (FAQ)

Q: Can the F1199AA20 replace the FN2010B-20-08 in all applications?

A: The F1199AA20 is electrically equivalent for 250VAC, 20A single-phase, single-stage filtering. However, the narrower frequency operating range (50/60Hz versus DC ~ 400Hz) and different termination style (quick connect versus threaded post M4) require system-level compatibility verification.

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

A: The FN2010B-20-08 operates across DC ~ 400Hz, making it suitable for applications with variable frequency drives, DC power supplies, or broadband noise sources. The F1199AA20 is limited to 50/60Hz standard utility frequencies. Application frequency requirements determine which part is appropriate.

Q: Are both parts RoHS compliant?

A: Yes, both the FN2010B-20-08 and F1199AA20 are ROHS3 compliant and REACH unaffected.

Q: How do the termination styles affect installation?

A: The FN2010B-20-08 uses threaded post (M4) termination requiring screw-based connections. The F1199AA20 uses quick connect termination for tool-free installation. System wiring and connector compatibility must match the selected termination style.

Q: Which part should be selected for new designs?

A: Selection depends on specific application requirements. For DC or extended frequency applications, the FN2010B-20-08 is required. For standard 50/60Hz utility applications with quick-connect preference, the F1199AA20 is suitable. Both parts are active and available.
