CE83B0394 Ferrite Core Equivalent & Substitute Parts

Part Overview

The CE83B0394 is a solid free hanging ferrite core manufactured by Leader Tech Inc., designed for electromagnetic interference (EMI) suppression applications. Specified at 130Ohm impedance @ 100MHz, this component features a 0.187" inner diameter and 0.394" outer diameter with a 0.787" length. The product is currently obsolete, making identification of suitable substitute components essential for ongoing system support and new design implementations where equivalent performance characteristics are required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CE83B0394 is based on the following critical parameters that define functional equivalence for ferrite core applications:

Core Substitution Criteria:

• Round ferrite core geometry with free hanging mounting capability
• Impedance value within acceptable range for EMI suppression (130Ohm baseline)
• Inner diameter accommodation for cable or conductor passage (minimum 0.187" / 4.75mm)
• Material composition suitable for the specified frequency range
• RoHS3 compliance and REACH unaffected status for regulatory alignment

The identified substitute HFA100049-0A2 maintains functional compatibility through equivalent impedance characteristics (133Ohm @ 300MHz), compatible inner diameter (0.192" / 4.88mm), and identical regulatory compliance status. The design variation from solid to hinged (snap-on) represents a mechanical enhancement that does not compromise electrical performance for EMI suppression applications.

Parameter Comparison

Engineering Selection Recommendations

The HFA100049-0A2 substitute is suitable for applications requiring CE83B0394 replacement based on the following factors:

Product Status: The CE83B0394 is obsolete with no ongoing manufacturing. The HFA100049-0A2 maintains active production status, ensuring long-term availability and supply chain continuity.

Regulatory Compliance: Both components maintain ROHS3 compliance and REACH unaffected status, satisfying current environmental and hazardous substance regulations applicable to electronic component procurement.

Electrical Characteristics: The impedance differential (130Ohm @ 100MHz versus 133Ohm @ 300MHz) represents a 2.3% variance with operation at a higher frequency specification, providing equivalent EMI suppression performance across standard application ranges.

Mechanical Considerations: The hinged design of HFA100049-0A2 provides installation flexibility compared to the solid design of CE83B0394. Dimensional increases in outer diameter and length require verification against available mounting space in the target application.

Frequently Asked Questions (FAQ)

Q: Can HFA100049-0A2 directly replace CE83B0394 in existing designs?

A: Electrical substitution is valid based on equivalent impedance and frequency characteristics. Physical space verification is required due to increased outer diameter (0.540" versus 0.394") and length (1.203" versus 0.787").

Q: What is the significance of the impedance frequency difference (100MHz vs 300MHz)?

A: The HFA100049-0A2 specification at 300MHz indicates superior high-frequency performance. The 133Ohm impedance at this higher frequency provides equivalent or superior EMI suppression across standard application frequency ranges.

Q: Does the hinged design affect electrical performance?

A: The hinged (snap-on) design of HFA100049-0A2 is a mechanical feature that does not alter core electrical characteristics. Impedance and frequency response remain functionally equivalent to solid core designs.

Q: Are there packaging or inventory considerations?

A: HFA100049-0A2 is available in bulk packaging with 57,975 pieces in stock, compared to CE83B0394 obsolete status with limited remaining inventory (1,120 pieces). New designs should specify HFA100049-0A2 for supply assurance.

Q: What certifications apply to both components?

A: Both CE83B0394 and HFA100049-0A2 maintain ROHS3 compliance and REACH unaffected status. ECCN classification is EAR99 for both components, with identical HTSUS code 8547.10.8000.
