ET28B3000 Ferrite Core Equivalent & Substitute Parts

Part Overview

The ET28B3000 is a hinged (snap-on) free hanging ferrite core manufactured by Leader Tech Inc. with an impedance rating of 370Ohm @ 100MHz. This component is classified as obsolete, making identification of suitable substitute parts essential for ongoing system support and component procurement.

The ET28B3000 features a round design with inner dimensions of 2.539" W x 0.059" H (64.50mm x 1.50mm) and outer dimensions of 3.701" W x 0.799" H (94.00mm x 20.30mm). Due to its obsolete status, sourcing alternatives from active product lines is necessary for new designs and system maintenance.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ET28B3000 is determined by the following critical parameters:

• Impedance Rating: 370Ohm @ 100MHz (electrical performance requirement)
• Design Configuration: Hinged (Snap On) (mechanical interface requirement)
• Material Composition: Material 28 (core material specification)
• Dimensional Specifications: Inner dimensions 2.539" W x 0.059" H (64.50mm x 1.50mm), outer dimensions 3.701" W x 0.799" H (94.00mm x 20.30mm), length 1.500" (38.10mm) (physical fit requirement)
• Mounting Type: Free Hanging (installation method)

The FA28B3000 qualifies as a direct substitute based on matching all critical electrical and mechanical parameters while maintaining compatibility with the original design specifications.

Parameter Comparison

Engineering Selection Recommendations

The FA28B3000 is the direct substitute for the obsolete ET28B3000. Both components are manufactured by Leader Tech Inc. and maintain identical electrical impedance characteristics (370Ohm @ 100MHz), material composition (Material 28), and mechanical dimensions. The FA28B3000 is currently in active production status, ensuring long-term availability and supply chain continuity.

Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for electronic component applications. The transition from ET28B3000 to FA28B3000 presents no electrical or mechanical compatibility issues for existing designs.

Frequently Asked Questions (FAQ)

Q: Can FA28B3000 directly replace ET28B3000 in existing applications?
