CTWBF-2.5 Ferrite Bead Equivalent & Substitute Parts

Part Overview

The CTWBF-2.5 is an axial ferrite bead manufactured by Central Technologies, rated at 580 Ohms impedance at 100 MHz. This component functions as an electromagnetic interference (EMI) filter element for single-line applications in through-hole mounting configurations. The part maintains Active product status with ROHS3 compliance and is currently in stock with 2,101 units available. Equivalent and substitute parts are identified to support procurement flexibility, inventory management, and supply chain continuity for applications requiring ferrite bead filtering with compatible electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitute parts for the CTWBF-2.5 are identified based on the following critical parameters that determine functional compatibility:

Primary Substitution Criteria:

• Package / Case: Axial (identical form factor)
• Mounting Type: Through Hole (identical mounting method)
• Size / Dimension: 0.236" Dia x 0.394" L (6.00mm x 10.00mm) (identical physical dimensions)
• Number of Lines: 1 (identical line configuration)
• RoHS Status: ROHS3 Compliant (identical compliance requirement)

Impedance Variation Allowance: Substitute parts are grouped to include ferrite beads with impedance values at 100 MHz that fall within the acceptable range for single-line axial ferrite bead applications. The CTWBF-2.5 operates at 580 Ohms @ 100 MHz, with the CTWBF-2.5-S variant rated at 675 Ohms @ 100 MHz representing a higher impedance option within the same series and physical envelope. The AWBC-03 from Abracon LLC provides an equivalent 580 Ohms @ 100 MHz specification from an alternative manufacturer, maintaining identical electrical performance with compatible mechanical specifications.

Engineering Selection Recommendations

CTWBF-2.5 (Primary Part): The CTWBF-2.5 is the specified component with Active product status and ROHS3 compliance. Selection of this part is appropriate for applications requiring 580 Ohms impedance at 100 MHz with Central Technologies manufacturing. Current inventory of 2,101 units supports standard procurement timelines.

CTWBF-2.5-S (Higher Impedance Variant): The CTWBF-2.5-S maintains identical physical dimensions, mounting configuration, and compliance certifications while providing 675 Ohms impedance at 100 MHz. This variant is suitable for applications requiring increased impedance filtering within the same form factor. The higher inventory level of 5,141 units provides enhanced supply availability. Selection of this part is appropriate when circuit design permits the higher impedance specification.

AWBC-03 (Alternative Manufacturer Equivalent): The AWBC-03 from Abracon LLC provides electrical equivalence to the CTWBF-2.5 with identical 580 Ohms @ 100 MHz impedance and matching physical dimensions. This part maintains ROHS3 compliance and Active product status. The AWBC-03 is suitable for applications where multi-source qualification is required or when Central Technologies inventory is unavailable. Moisture Sensitivity Level is rated at 1 (Unlimited) and REACH status is Unaffected, providing additional compliance documentation.

Frequently Asked Questions (FAQ)

Q: Can the CTWBF-2.5-S be used as a direct replacement for the CTWBF-2.5?

A: The CTWBF-2.5-S shares identical physical dimensions, axial package configuration, through-hole mounting type, and compliance certifications. The primary difference is impedance specification: 675 Ohms @ 100 MHz versus 580 Ohms @ 100 MHz. Direct substitution is possible only if circuit design specifications permit the higher impedance value. Verify impedance requirements in the application schematic before selection.

Q: What is the difference between the CTWBF-2.5 and AWBC-03?

A: Both parts provide 580 Ohms impedance at 100 MHz with identical physical dimensions (0.236" Dia x 0.394" L) and axial through-hole mounting. The primary difference is manufacturer: Central Technologies (CTWBF-2.5) versus Abracon LLC (AWBC-03). Both maintain ROHS3 compliance and Active product status. The AWBC-03 provides an alternative source for equivalent electrical and mechanical performance.

Q: Are all three parts physically interchangeable?

A: Yes. All three parts share identical physical dimensions of 0.236" Dia x 0.394" L (6.00mm x 10.00mm), axial package configuration, and through-hole mounting type. Physical interchangeability is confirmed across all substitute options.

Q: Which part should be selected for new designs?

A: For new designs, the CTWBF-2.5 is the primary specification. If higher impedance filtering is required within the same form factor, the CTWBF-2.5-S is appropriate. If multi-source qualification or alternative manufacturer sourcing is required, the AWBC-03 provides equivalent electrical performance. Selection depends on circuit impedance requirements and procurement strategy.

Q: What compliance certifications apply to all substitute parts?

A: All three parts maintain ROHS3 compliance. The AWBC-03 provides additional compliance documentation including Moisture Sensitivity Level 1 (Unlimited), REACH Unaffected status, ECCN EAR99, and HTSUS 8548.00.0000 classification.

Q: Are there inventory considerations for part selection?

A: Current inventory levels are: CTWBF-2.5 (2,101 units), CTWBF-2.5-S (5,141 units), and AWBC-03 (1,775 units). The CTWBF-2.5-S offers the highest inventory availability. Selection based on inventory should be coordinated with circuit design requirements and impedance specifications.
