ACB2012H-060-T Equivalent & Substitute Parts

Part Overview

The ACB2012H-060-T is a signal line ferrite bead manufactured by TDK Corporation in the 0805 (2012 Metric) package. This component provides 60 Ohms of impedance at 100 MHz with a maximum current rating of 300mA and DC resistance of 500mOhm. The part is classified as obsolete, making identification of suitable substitute components necessary for ongoing design support and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ACB2012H-060-T is determined by the following critical parameters:

• Package compatibility: 0805 (2012 Metric) surface mount form factor
• Filter application: Single signal line ferrite bead
• Current capacity: 300mA maximum rating
• Impedance range: 60 Ohms nominal at 100 MHz
• Physical dimensions: 0.079" L x 0.049" W with maximum height of 0.043"
• Moisture sensitivity: MSL 1 (Unlimited)

The FB201209T-700Y-S from Cal-Chip Electronics qualifies as a parametric equivalent based on matching package, mounting type, current rating, and physical dimensions. The impedance specification of 70 Ohms at 100 MHz represents a 16.7% increase from the original 60 Ohms specification, which falls within acceptable tolerance for ferrite bead substitution in signal line applications where exact impedance matching is not critical to circuit function.

Parameter Comparison

Engineering Selection Recommendations

The FB201209T-700Y-S is suitable for applications requiring replacement of the obsolete ACB2012H-060-T. The substitute part maintains identical package geometry, current rating, and mounting characteristics. The impedance increase from 60 Ohms to 70 Ohms represents a minor specification variance acceptable in signal line ferrite bead applications. The FB201209T-700Y-S offers the additional advantage of active product status and RoHS compliance, supporting long-term supply chain continuity and regulatory alignment.

Frequently Asked Questions (FAQ)

Q: Can the FB201209T-700Y-S be used as a direct replacement for the ACB2012H-060-T?

A: Yes. Both components share identical package dimensions (0805 / 2012 Metric), current rating (300mA), mounting type (surface mount), and physical height (0.043"). The impedance difference of 10 Ohms at 100 MHz is within acceptable tolerance for signal line ferrite bead applications.

Q: What is the significance of the impedance difference between 60 Ohms and 70 Ohms?

A: The 16.7% impedance increase provides slightly higher attenuation in the target frequency range. For signal line filtering applications, this variance does not typically affect circuit performance. Circuit validation is the responsibility of the design engineer.

Q: Why is the ACB2012H-060-T listed as obsolete?

A: Obsolete status indicates the part is no longer manufactured by TDK Corporation. The FB201209T-700Y-S provides equivalent functionality with active manufacturing status and improved compliance certifications.

Q: Are there packaging differences between these parts?

A: No. Both parts are supplied in 0805 (2012 Metric) surface mount packages with identical physical dimensions and height specifications. The FB201209T-700Y-S is available in Tape & Reel (TR) packaging format.

Q: Does the lower DC resistance of the FB201209T-700Y-S affect compatibility?

A: No. The FB201209T-700Y-S exhibits lower DC resistance (200mOhm versus 500mOhm), which represents an improvement in electrical performance and does not create compatibility issues in signal line applications.

Q: What compliance certifications apply to each part?

A: The ACB2012H-060-T is RoHS non-compliant. The FB201209T-700Y-S is RoHS compliant. Both parts are REACH unaffected and classified under ECCN EAR99.
