LINE FILTER 02EK33 - Equivalent & Substitute Parts

Part Overview

The Curtis Industries 02EK33 is a single-phase EMC/EMI line filter rated for 250VAC at 2A with 50/60Hz operation. This chassis-mount component features wire lead termination and is designed for general-purpose filtering applications. The 02EK33 carries an obsolete product status, making identification of compatible substitute parts essential for ongoing system maintenance and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 02EK33 is determined by electrical and mechanical parameter alignment. The substitute part F1299BB02 maintains functional equivalence through matching specifications across all critical parameters: single-phase filter configuration, 250VAC rated voltage, 2A current capacity, 50/60Hz operating frequency, chassis mount design, and wire lead termination. Both parts carry identical regulatory approvals (CSA, UR, VDE) and serve general-purpose applications. The F1299BB02 represents an active product status alternative to the obsolete 02EK33, with improved RoHS3 compliance and defined moisture sensitivity rating.

Parameter Comparison

Engineering Selection Recommendations

The F1299BB02 serves as the direct substitute for the obsolete 02EK33. Both components satisfy identical electrical and mechanical requirements for single-phase EMC/EMI filtering at 250VAC, 2A, with 50/60Hz operation. The F1299BB02 provides the advantage of active product status, ensuring continued availability and supply chain reliability. Additionally, the F1299BB02 achieves ROHS3 compliance, addressing modern regulatory requirements that may apply to end-use applications. Regulatory certifications remain consistent between both parts (CSA, UR, VDE), supporting direct substitution in existing designs without certification re-evaluation.

Frequently Asked Questions (FAQ)

Q: Can the F1299BB02 directly replace the 02EK33 in existing designs? A: Yes. Both components share identical electrical ratings (250VAC, 2A, 50/60Hz), filter configuration (single-phase, single-stage), mounting type (chassis mount), and termination style (wire leads). Regulatory approvals are equivalent across both parts.

Q: What is the primary reason for substitution? A: The 02EK33 carries obsolete product status. The F1299BB02 is an active product offering equivalent functionality with improved compliance characteristics.

Q: Are there packaging differences between these parts? A: The 02EK33 is specified with dash packaging notation, while the F1299BB02 is supplied in bulk packaging. This distinction does not affect electrical or mechanical compatibility.

Q: Does the RoHS compliance difference affect substitution? A: The F1299BB02 achieves ROHS3 compliance, whereas the 02EK33 is RoHS non-compliant. For applications subject to RoHS regulations, the F1299BB02 provides regulatory alignment. For legacy systems without RoHS requirements, both parts remain functionally equivalent.

Q: Are the regulatory certifications identical? A: Yes. Both the 02EK33 and F1299BB02 carry CSA, UR, and VDE approvals, supporting direct substitution without additional certification requirements.
