ACB2012H-030-T Equivalent & Substitute Parts

Part Overview

The ACB2012H-030-T is a single-line ferrite bead manufactured by TDK Corporation in the 0805 (2012 Metric) surface mount package. This component provides 30 Ohms of impedance at 100 MHz with a maximum current rating of 300mA and 400mOhm DC resistance. The part is classified as obsolete, making equivalent substitutes necessary for ongoing production and design requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the ACB2012H-030-T is determined by the following critical parameters:

• Package / Case: All substitutes must be 0805 (2012 Metric) surface mount
• Mounting Type: Surface mount configuration required
• Filter Type: Single signal line ferrite bead
• Current Rating: 300mA maximum
• Impedance Range: 26 Ohms to 33 Ohms @ 100 MHz (within acceptable tolerance band)
• DC Resistance: Substitutes range from 100mOhm to 150mOhm, lower than the original 400mOhm specification
• Physical Dimensions: 0.079" L x 0.049" W (2.00mm x 1.25mm) with 0.043" (1.10mm) maximum height

All substitute parts are manufactured by Cal-Chip Electronics, Inc. and are available in active product status with RoHS compliance and Tape & Reel packaging.

Parameter Comparison

Engineering Selection Recommendations

FB201209T-300Y-S provides the closest electrical match to the ACB2012H-030-T, with identical 30 Ohms impedance at 100 MHz and 300mA current rating. This part is in active production status and RoHS compliant, addressing the obsolescence of the original component.

FB201209T-260Y-S, FB201209T-320Y-S, and FB201209T-330Y-S are alternative selections within the impedance tolerance band (26–33 Ohms @ 100 MHz). All substitute parts maintain the same 300mA current rating, 0805 package footprint, and surface mount configuration. All Cal-Chip substitutes feature lower DC resistance (100–150mOhm) compared to the original 400mOhm specification and carry RoHS compliance certification.

Frequently Asked Questions (FAQ)

Q: Can FB201209T-300Y-S be used as a direct replacement for ACB2012H-030-T?

A: Yes. Both parts share identical impedance (30 Ohms @ 100 MHz), current rating (300mA), package (0805 / 2012 Metric), and physical dimensions. The substitute has lower DC resistance (150mOhm vs. 400mOhm) and is RoHS compliant.

Q: Are the other substitute parts (260Y, 320Y, 330Y) acceptable alternatives?

A: Yes, within the specified impedance tolerance band of 26–33 Ohms @ 100 MHz. Selection depends on circuit requirements for impedance matching at 100 MHz. All maintain 300mA current rating and identical package specifications.

Q: What is the impact of lower DC resistance in the substitute parts?

A: The Cal-Chip substitutes feature DC resistance of 100–150mOhm, lower than the original 400mOhm. This reduces resistive losses and heat generation in the ferrite bead, which is generally beneficial for signal integrity applications.

Q: Are all substitute parts available in the same packaging format?

A: All Cal-Chip substitutes are supplied in Tape & Reel (TR) format. The original ACB2012H-030-T packaging format is not specified in the provided data.

Q: Do the substitute parts meet RoHS requirements?

A: Yes. All Cal-Chip substitute parts (FB201209T series) are RoHS compliant. The original ACB2012H-030-T is RoHS non-compliant.
