LINE FILTER 250VAC 10A CHASSIS MOUNT 10ER66

Part Overview

The Curtis Industries 10ER66 is a single-phase EMC/EMI line filter rated for 250VAC at 10A with 50/60Hz operation. This component is classified as obsolete, making direct replacement necessary for new designs and ongoing system maintenance. The 10ER66 features a two-stage configuration with quick connect termination and chassis mount installation. As an obsolete product, equivalent substitute parts must be identified to maintain system functionality and ensure continued availability for applications requiring single-phase line filtering at this voltage and current rating.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 10ER66 is determined by the following critical electrical and mechanical parameters:

Electrical Compatibility Requirements:

• Single-phase filter configuration
• 250V AC rated voltage
• 10A current rating
• 50/60Hz operating frequency

Mechanical Compatibility Requirements:

• Chassis mount installation capability
• Compatible termination interface

The primary substitute identified is the Curtis Industries F1399DD10, which maintains all critical electrical parameters (single-phase, two-stage, 250V, 10A, 50/60Hz) and chassis mount configuration. The F1399DD10 differs in termination style (threaded post 8-32 versus quick connect) and product status (active versus obsolete), but satisfies the core functional requirements for line filtering applications.

Parameter Comparison

Engineering Selection Recommendations

The F1399DD10 serves as the primary substitute for the obsolete 10ER66 based on electrical and mechanical parameter alignment. Both components are manufactured by Curtis Industries and maintain identical ratings for voltage, current, frequency, and filter configuration.

The F1399DD10 offers the advantage of active product status, ensuring continued availability and supply chain reliability. The component carries expanded regulatory approvals (CE, CSA, TUV, UR) compared to the 10ER66 (CSA, UR, VDE) and meets ROHS3 compliance requirements, whereas the 10ER66 is RoHS non-compliant.

The primary design consideration is termination interface compatibility. The 10ER66 uses quick connect termination, while the F1399DD10 employs threaded post (8-32) termination. System integration must accommodate this mechanical difference through appropriate connector adaptation or circuit board redesign.

Frequently Asked Questions (FAQ)

Q: Can the F1399DD10 directly replace the 10ER66 without modification?

A: The F1399DD10 matches all critical electrical parameters (250V, 10A, single-phase, two-stage, 50/60Hz) and mounting type. However, termination interface differs: the 10ER66 uses quick connect while the F1399DD10 uses threaded post (8-32). System integration requires termination compatibility assessment.

Q: Why is the 10ER66 classified as obsolete?

A: The 10ER66 is no longer in active production. The F1399DD10 represents the active product line continuation from Curtis Industries for this application category.

Q: Are there regulatory compliance differences between these parts?

A: Yes. The 10ER66 holds CSA, UR, and VDE approvals and is RoHS non-compliant. The F1399DD10 carries CE, CSA, TUV, and UR approvals and meets ROHS3 compliance. Applications requiring specific regulatory certifications must verify alignment with system requirements.

Q: What is the packaging difference?

A: The 10ER66 packaging is listed as dash (standard). The F1399DD10 is supplied in box packaging.

Q: Are there other Curtis Industries substitutes available?

A: The F1399DD10 is identified as the direct substitute within the provided data. Additional Curtis Industries alternatives (10VS1, 10EMC6, 10VR1, 10EMC1, 1-6609031-3) are listed as secondary substitutes for the F1399DD10 but are not directly compared in this reference.
