Key Parameters

Substitute Part Grouping Explanation

Substitution of the ET28B2000 is based on the following critical parameters that must remain consistent:

• Impedance @ Frequency: 380Ohm @ 100MHz (electrical performance requirement)
• Inner Dimension: 1.000" Dia (25.40mm) (mechanical fit requirement)
• Design: Hinged (Snap On) (functional requirement)
• Material: 28 (ferrite material specification)
• Mounting Type: Free Hanging (installation requirement)

The CW28B2000 meets all substitution criteria. While the outer diameter and length differ slightly from the ET28B2000, these dimensional variations remain within acceptable tolerances for the hinged ferrite core category and do not affect core electrical performance or mechanical compatibility with standard 1.000" inner diameter cable applications.

Parameter Comparison

Engineering Selection Recommendations

The CW28B2000 is the manufacturer-recommended substitute for the obsolete ET28B2000. Both components are manufactured by Leader Tech Inc. and maintain identical electrical specifications (380Ohm @ 100MHz) and core mechanical requirements (1.000" inner diameter, hinged snap-on design, ferrite material 28). Both parts are ROHS3 compliant and REACH unaffected.

The CW28B2000 is currently in active production status with confirmed inventory availability, whereas the ET28B2000 is obsolete. For new designs and ongoing procurement, the CW28B2000 is the appropriate selection. The minor dimensional variations in outer diameter and length do not impact electrical performance or compatibility with standard cable applications utilizing 1.000" inner diameter ferrite cores.

Frequently Asked Questions (FAQ)

Q: Can the CW28B2000 directly replace the ET28B2000 in existing applications?

A: Yes. Both parts share identical impedance specifications (380Ohm @ 100MHz), inner diameter (1.000"), hinged snap-on design, and ferrite material composition. The outer diameter and length variations are within acceptable tolerances for this component category.

Q: What is the primary reason for substitution?

A: The ET28B2000 is classified as obsolete. The CW28B2000 is the manufacturer-recommended active substitute that maintains all critical electrical and mechanical parameters.

Q: Are there compliance differences between the two parts?

A: No. Both the ET28B2000 and CW28B2000 are ROHS3 compliant and REACH unaffected.

Q: What packaging is available for the CW28B2000?

A: The CW28B2000 is supplied in bulk packaging.

Q: Are both parts suitable for free hanging mounting applications?

A: Yes. Both the ET28B2000 and CW28B2000 are designed for free hanging mounting type installations.
