Curtis Industries 20EB66 Line Filter - Equivalent & Substitute Parts

Part Overview

The Curtis Industries 20EB66 is a single-phase EMC/EMI line filter rated for 250VAC at 20A with 50/60Hz operation. This chassis-mount filter features quick-connect termination and is designed for general-purpose applications requiring electromagnetic compatibility filtering.

The 20EB66 is classified as obsolete. Locating equivalent substitute parts is necessary to maintain system functionality and ensure continued availability for replacement or new installations where this filter specification is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 20EB66 is determined by matching the following critical electrical and mechanical parameters:

• Voltage rating: 250VAC
• Current capacity: 20A
• Frequency compatibility: 50/60Hz operation
• Filter configuration: Single-phase, single-stage
• Mounting interface: Chassis mount
• Application category: General purpose EMC/EMI filtering

The substitute part F1199DD20 maintains electrical equivalence across all rated parameters. The primary difference is the termination style: the 20EB66 uses quick-connect termination, while the F1199DD20 uses threaded post (8-32) termination. This difference requires mechanical interface adaptation during installation but does not affect electrical performance or filtering characteristics.

Parameter Comparison

Engineering Selection Recommendations

The F1199DD20 is the direct electrical equivalent for the 20EB66. Both parts maintain identical voltage, current, frequency, and filtering specifications. The F1199DD20 is currently in active production status, ensuring availability for replacement applications.

The F1199DD20 provides enhanced regulatory compliance with ROHS3 certification and expanded approval agency recognition (CE, CSA, TUV, UR) compared to the 20EB66. The primary consideration for selection is termination interface compatibility: the quick-connect termination of the 20EB66 must be adapted to the threaded post (8-32) connection of the F1199DD20 during installation.

Frequently Asked Questions (FAQ)

Q: Can the F1199DD20 directly replace the 20EB66 without modification?

A: The F1199DD20 is electrically equivalent and will perform the same filtering function. However, the termination interface differs: the 20EB66 uses quick-connect termination while the F1199DD20 uses threaded post (8-32) connections. The installation harness or connection method must be adapted accordingly.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution is valid when the following parameters match: 250VAC voltage rating, 20A current capacity, 50/60Hz frequency operation, single-phase single-stage configuration, and chassis-mount form factor. All these parameters are identical between the 20EB66 and F1199DD20.

Q: Why is the 20EB66 obsolete?

A: The 20EB66 is classified as obsolete by the manufacturer. The F1199DD20 represents the active-production equivalent that supersedes this part.

Q: Are there regulatory compliance differences between these parts?

A: Yes. The 20EB66 is RoHS non-compliant, while the F1199DD20 is ROHS3 compliant. The F1199DD20 also carries broader regulatory approvals (CE, CSA, TUV, UR) compared to the 20EB66 (CSA, UR, VDE).

Q: What is the difference in packaging?

A: The 20EB66 is supplied with standard packaging, while the F1199DD20 is supplied in a box. This difference does not affect the component's electrical or mechanical function.
