CTWBF-2.5-S Ferrite Bead Equivalent & Substitute Parts

Part Overview

The CTWBF-2.5-S is an axial ferrite bead manufactured by Central Technologies, rated at 675 Ohms @ 100 MHz. This component is designed for electromagnetic interference (EMI) suppression and signal integrity applications in through-hole mounted configurations. The part maintains Active product status with ROHS3 compliance. Substitute parts are identified when equivalent electrical performance, mechanical compatibility, and regulatory compliance can be maintained across alternative manufacturers or product variants within the same series.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the CTWBF-2.5-S are identified based on the following criteria:

Primary Substitution Parameters:

• Package / Case: Axial configuration
• Mounting Type: Through Hole
• Size / Dimension: 0.236" Dia x 0.394" L (6.00mm x 10.00mm)
• Number of Lines: 1
• RoHS Status: ROHS3 Compliant
• Product Status: Active

Impedance Tolerance Consideration: The CTWBF-2.5-S operates at 675 Ohms @ 100 MHz. Substitute part CTWBF-2.5 and AWBC-03 both operate at 580 Ohms @ 100 MHz, representing a 14% impedance variance. These parts share identical mechanical and regulatory specifications but differ in impedance rating. Selection between these parts depends on circuit-specific impedance requirements.

Parameter Comparison

Engineering Selection Recommendations

CTWBF-2.5 (Central Technologies): This part is a direct series equivalent within the CTWBF product line. It maintains identical mechanical specifications, through-hole mounting configuration, and ROHS3 compliance. The 580 Ohms @ 100 MHz impedance rating differs from the primary part. Selection of CTWBF-2.5 is appropriate when circuit design specifications permit the lower impedance value or when supply chain availability of the CTWBF-2.5-S is constrained. Both parts share the same manufacturer and series designation.

AWBC-03 (Abracon LLC): This part provides cross-manufacturer substitution with identical mechanical and electrical specifications to CTWBF-2.5. The AWBC-03 offers defined Moisture Sensitivity Level (MSL 1 - Unlimited) and confirmed REACH Unaffected status, providing enhanced regulatory documentation clarity compared to the primary part. The 580 Ohms @ 100 MHz impedance matches CTWBF-2.5. Selection of AWBC-03 is appropriate when cross-manufacturer sourcing is required or when explicit MSL and REACH documentation is mandated by procurement specifications.

Frequently Asked Questions (FAQ)

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

A: CTWBF-2.5 shares identical mechanical specifications, package type, mounting configuration, and regulatory compliance with CTWBF-2.5-S. The impedance rating differs: CTWBF-2.5 operates at 580 Ohms @ 100 MHz versus 675 Ohms @ 100 MHz for CTWBF-2.5-S. Substitution is valid only when circuit design specifications accommodate the 580 Ohms impedance value.

Q: What is the impedance difference between CTWBF-2.5-S and its substitutes?

A: CTWBF-2.5-S is rated at 675 Ohms @ 100 MHz. Both substitute parts (CTWBF-2.5 and AWBC-03) are rated at 580 Ohms @ 100 MHz, representing approximately 14% lower impedance. This difference must be evaluated against circuit-specific EMI suppression and signal integrity requirements.

Q: Are all three parts mechanically interchangeable?

A: Yes. CTWBF-2.5-S, CTWBF-2.5, and AWBC-03 share identical physical dimensions (0.236" Dia x 0.394" L / 6.00mm x 10.00mm), axial package configuration, and through-hole mounting type. No mechanical modifications are required for board-level substitution.

Q: What is the difference in regulatory compliance between these parts?

A: All three parts are ROHS3 compliant and maintain Active product status. AWBC-03 provides explicit MSL 1 (Unlimited) designation and confirmed REACH Unaffected status. CTWBF-2.5-S and CTWBF-2.5 list MSL as Vendor Undefined and REACH status as available upon request. When regulatory documentation specificity is required, AWBC-03 provides complete compliance clarity.

Q: Can I substitute AWBC-03 for CTWBF-2.5-S in a production environment?

A: AWBC-03 provides cross-manufacturer substitution with matching mechanical specifications and ROHS3 compliance. The 580 Ohms @ 100 MHz impedance differs from CTWBF-2.5-S (675 Ohms @ 100 MHz). Substitution is valid when circuit design specifications permit the lower impedance value and when cross-manufacturer sourcing is acceptable within procurement guidelines.

Q: What inventory levels are available for each part?

A: CTWBF-2.5-S: 5141 Pcs New Original In Stock. CTWBF-2.5: 2101 Pcs New Original In Stock. AWBC-03: 1775 Pcs New Original In Stock. All parts are available in bulk packaging.
