CTWBF-3.0 Ferrite Bead Equivalent & Substitute Parts

Part Overview

The CTWBF-3.0 is a single-line ferrite bead with radial through-hole mounting, manufactured by Central Technologies. This component provides electromagnetic interference (EMI) filtering at 550 Ohms impedance measured at 100 MHz. The part is currently in active production status with 1292 units available in inventory. Substitute parts are identified when equivalent functional performance can be achieved within the allowed electrical and mechanical parameters of the ferrite bead category, particularly when the primary part becomes unavailable or when alternative impedance values are acceptable for the application circuit.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CTWBF-3.0 ferrite bead is determined by equivalence in the following critical parameters:

Mandatory Matching Parameters:

• Number of Lines: 1 (single-line configuration)
• Package / Case: Radial (physical form factor)
• Mounting Type: Through Hole (PCB assembly method)
• Height (Max): 0.404" (10.25mm) (vertical clearance compatibility)
• Size / Dimension: 0.236" Dia (6.00mm) (footprint compatibility)
• Series: CTWBF (manufacturer product line)

Allowable Variation Parameter:

• Impedance @ Frequency: Substitute parts within the CTWBF series may vary in impedance value at 100 MHz, provided the application circuit tolerates the impedance difference

The CTWBF-2.0-S substitute part maintains identical mechanical and mounting specifications while providing 600 Ohms @ 100 MHz impedance, representing a 50 Ohm increase from the primary part. Both parts share ROHS3 compliance and active production status.

Engineering Selection Recommendations

Primary Part Selection: The CTWBF-3.0 is the specified component for applications requiring 550 Ohms impedance at 100 MHz. This part maintains active production status with robust inventory availability (1292 units). ROHS3 compliance and bulk packaging support high-volume manufacturing environments.

Substitute Part Selection: The CTWBF-2.0-S substitute is electrically and mechanically compatible for applications where 600 Ohms @ 100 MHz impedance is acceptable. The 50 Ohm impedance increase represents an 8.3% variation from the primary specification. Both parts share identical mechanical dimensions, mounting characteristics, and regulatory compliance certifications. The substitute part is suitable for component sourcing when the primary part experiences supply constraints, provided circuit design tolerates the impedance differential.

Compliance Considerations: Both the CTWBF-3.0 and CTWBF-2.0-S meet ROHS3 compliance requirements. REACH status information is available upon request from Central Technologies for applications requiring full regulatory documentation.

Frequently Asked Questions (FAQ)

Q: Can the CTWBF-2.0-S directly replace the CTWBF-3.0 in my circuit?

A: Direct mechanical and electrical substitution is possible if the application circuit design tolerates 600 Ohms impedance at 100 MHz instead of 550 Ohms. The 50 Ohm impedance increase will alter EMI filtering characteristics. Circuit validation is required to confirm performance acceptability.

Q: Are the physical dimensions identical between CTWBF-3.0 and CTWBF-2.0-S?

A: Yes. Both parts share identical radial package specifications: 0.404" (10.25mm) maximum height and 0.236" (6.00mm) diameter. PCB footprint and mounting hole requirements are identical for through-hole assembly.

Q: What is the impedance difference between these parts?

A: The CTWBF-3.0 provides 550 Ohms @ 100 MHz, while the CTWBF-2.0-S provides 600 Ohms @ 100 MHz. This represents a 50 Ohm increase or 8.3% impedance variation.

Q: Are both parts RoHS compliant?

A: Yes. Both the CTWBF-3.0 and CTWBF-2.0-S are ROHS3 compliant. REACH compliance information is available upon request from Central Technologies.

Q: Which part should I select if both are available?

A: Select the CTWBF-3.0 if your circuit design specifies 550 Ohms @ 100 MHz impedance. Select the CTWBF-2.0-S only if your application circuit design accepts 600 Ohms @ 100 MHz impedance and the primary part is unavailable.

Q: What is the current inventory status?

A: The CTWBF-3.0 has 1292 units in stock. The CTWBF-2.0-S substitute has 674 units in stock. Both are available as new original components in bulk packaging.
