KEMET B-01-AT1F Ferrite Bead Equivalent & Substitute Parts

Part Overview

The KEMET B-01-AT1F is a signal line ferrite bead designed for electromagnetic interference (EMI) suppression in electronic circuits. This axial-mounted component provides 2 Ohms of impedance at 1 MHz with a maximum current rating of 5A. The part is currently in active production status with full RoHS3 compliance and REACH unaffected certification. Substitute parts are identified when inventory constraints, packaging format requirements, or supply chain considerations necessitate alternative sourcing while maintaining identical electrical and mechanical performance.

Substitute Part Grouping Explanation

Substitution eligibility for the B-01-AT1F is determined by strict equivalence across the following critical parameters:

  • Impedance value: 2 Ohms @ 1 MHz
  • Current rating: 5A maximum
  • Filter type: Signal Line (single line)
  • Package type: Axial
  • Mounting method: Through Hole
  • Physical dimensions: 0.134" Dia x 2.638" L (3.40mm x 67.00mm)
  • Operating temperature range: -20°C ~ 70°C
  • Regulatory compliance: RoHS3 Compliant, REACH Unaffected

Substitute parts must match all electrical specifications and physical dimensions. Packaging format (Tape & Reel versus Cut Tape) represents the only allowable variation, as both formats contain identical components with different supply configurations.

Engineering Selection Recommendations

Both the B-01-AT1F and B-01-ATF are active production components manufactured by KEMET within the BEAD L series. Selection between these parts should be based on packaging requirements and inventory availability:

The B-01-AT1F in Tape & Reel format is suitable for high-volume automated assembly operations where continuous strip feeding is required. The B-01-ATF in Cut Tape format accommodates lower-volume production runs, manual assembly processes, or applications where individual component handling is preferred.

Both parts maintain identical electrical performance, physical dimensions, and regulatory compliance status. The choice between them does not affect circuit functionality or performance characteristics.

Frequently Asked Questions (FAQ)

Q: Can B-01-ATF be used as a direct replacement for B-01-AT1F in production?

A: Yes. Both parts are electrically and mechanically identical. The only difference is packaging format (Tape & Reel versus Cut Tape). Selection depends on assembly process requirements and equipment compatibility.

Q: Are there any performance differences between the two parts?

A: No. Both parts deliver identical impedance (2 Ohms @ 1 MHz), current rating (5A), operating temperature range (-20°C ~ 70°C), and physical dimensions (0.134" Dia x 2.638" L).

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both B-01-AT1F and B-01-ATF are RoHS3 Compliant and REACH Unaffected.

Q: What is the difference between Tape & Reel and Cut Tape packaging?

A: Tape & Reel packaging supplies components on continuous carrier tape wound on a reel, optimized for automated pick-and-place assembly. Cut Tape packaging supplies the same components on shorter tape segments, suitable for manual handling or lower-volume assembly.

Q: Can these parts be interchanged mid-production?

A: Yes, provided the assembly equipment can accommodate the packaging format. Electrical and mechanical specifications are identical, ensuring no circuit performance impact.
