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

Part Overview

The KEMET B-01-AT is a 2 Ohm axial ferrite bead designed for single-line signal filtering applications. This component is classified as obsolete, making equivalent substitute parts necessary for ongoing design support and procurement. The B-01-AT provides electromagnetic interference (EMI) suppression in through-hole axial configurations with a maximum current rating of 5A and operates across the temperature range of -20°C to 70°C.

Substitute Part Grouping Explanation

Substitution of the B-01-AT is determined by strict equivalence across the following critical parameters:

• Impedance specification: 2 Ohms @ 1 MHz
• Filter type: Signal Line (single line)
• Current rating: 5A maximum
• Physical dimensions: 0.134" Dia x 2.638" L (3.40mm x 67.00mm)
• Package type: Axial through-hole
• Operating temperature range: -20°C ~ 70°C
• Regulatory compliance: ROHS3 Compliant, REACH Unaffected

The substitute parts B-01-AT1F and B-01-ATF maintain identical electrical and mechanical specifications. Differentiation between these parts is based solely on packaging format: Tape & Reel (TR) for B-01-AT1F and Cut Tape (CT) for B-01-ATF. Both substitutes are classified as active products, providing long-term availability compared to the obsolete B-01-AT.

Parameter Comparison

Engineering Selection Recommendations

Both B-01-AT1F and B-01-ATF are direct functional equivalents to the obsolete B-01-AT. Selection between these two active substitutes depends on procurement and assembly requirements:

B-01-AT1F (Tape & Reel packaging) is suitable for high-volume automated assembly operations where tape-fed component handling is standard.

B-01-ATF (Cut Tape packaging) is appropriate for lower-volume applications, prototype builds, or manual assembly processes where individual component access is required.

Both substitutes maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment with the original part. Current inventory levels are 745 Pcs for B-01-AT1F and 647 Pcs for B-01-ATF, supporting immediate procurement needs.

Frequently Asked Questions (FAQ)

Q: Can B-01-AT1F and B-01-ATF be used interchangeably with B-01-AT?

A: Yes. Both substitute parts maintain identical electrical specifications (2 Ohms @ 1 MHz), current rating (5A), physical dimensions (0.134" Dia x 2.638" L), and operating temperature range (-20°C ~ 70°C). The only difference is packaging format.

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

A: Tape & Reel (TR) packaging supplies components on continuous carrier tape wound on reels, optimized for automated pick-and-place assembly. Cut Tape (CT) packaging provides components on tape segments, suitable for manual handling and lower-volume applications.

Q: Are the substitute parts compliant with the same regulatory standards?

A: Yes. Both B-01-AT1F and B-01-ATF are ROHS3 compliant and REACH unaffected, matching the regulatory status of the original B-01-AT.

Q: Why is the B-01-AT classified as obsolete?

A: The B-01-AT is no longer in active production. However, direct functional equivalents remain available through the active substitute parts B-01-AT1F and B-01-ATF.

Q: Which substitute should I select for new designs?

A: For new designs, either B-01-AT1F or B-01-ATF can be selected based on your assembly process. Tape & Reel format (B-01-AT1F) is recommended for automated manufacturing; Cut Tape format (B-01-ATF) is recommended for manual or low-volume assembly.
