LINE FILTER 250VAC 10A CHASSIS - 10EK66 Equivalent & Substitute Parts

Part Overview

The Curtis Industries 10EK66 is a single phase EMC/EMI line filter rated for 250VAC at 10A with 50/60Hz operation. This chassis mount filter is designed for general purpose applications requiring electromagnetic compatibility filtering. The 10EK66 is classified as obsolete, making identification of active equivalent parts essential for ongoing procurement and system maintenance. Substitute parts must maintain identical electrical ratings and core functional specifications to ensure proper EMI/EMC filtering performance in replacement scenarios.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 10EK66 is based on strict equivalence of electrical and mechanical parameters. The following criteria determine valid substitutes:

• Single phase filter configuration with single stage topology
• 250VAC rated voltage with 10A current capacity
• 50/60Hz operating frequency compatibility
• Chassis mount form factor
• Equivalent approval certifications (CSA, UR, VDE)
• General purpose application suitability

The F1299DD10 meets all these core substitution criteria. The primary difference between the 10EK66 and F1299DD10 lies in termination style: the 10EK66 uses quick connect termination, while the F1299DD10 employs threaded post (8-32) termination. This difference requires mechanical interface verification during integration but does not affect electrical filtering performance or ratings.

Parameter Comparison

Engineering Selection Recommendations

The F1299DD10 is the direct electrical equivalent for the obsolete 10EK66. Both parts maintain identical voltage, current, frequency, and filtering specifications with equivalent regulatory certifications from CSA, UR, and VDE.

The F1299DD10 offers the advantage of active product status, ensuring continued availability and supply chain reliability. Additionally, the F1299DD10 achieves ROHS3 compliance, whereas the 10EK66 is non-compliant, making the F1299DD10 preferable for applications subject to RoHS regulations.

The termination interface difference (quick connect versus threaded post 8-32) requires mechanical redesign or adapter consideration during implementation. This is the only integration factor that must be evaluated during component selection.

Frequently Asked Questions (FAQ)

Q: Can the F1299DD10 directly replace the 10EK66 without circuit modification?

A: The F1299DD10 is electrically equivalent and requires no circuit modifications. However, the termination style differs: the 10EK66 uses quick connect while the F1299DD10 uses threaded post (8-32). Mechanical interface adaptation is necessary.

Q: Are the filtering characteristics identical between these parts?

A: Yes. Both parts are single phase, single stage EMC/EMI line filters with identical voltage (250VAC), current (10A), and frequency (50/60Hz) ratings. Filtering performance is equivalent.

Q: What is the significance of the RoHS compliance difference?

A: The F1299DD10 is ROHS3 compliant while the 10EK66 is non-compliant. For applications subject to RoHS regulations or customer requirements, the F1299DD10 is the appropriate selection.

Q: Are both parts approved by the same regulatory agencies?

A: Yes. Both the 10EK66 and F1299DD10 carry CSA, UR, and VDE approvals, ensuring equivalent regulatory acceptance.

Q: What packaging is available for the F1299DD10?

A: The F1299DD10 is supplied in box packaging.
