ACML-0201-800-T Ferrite Bead 80 Ohm 0201 Equivalent & Substitute Parts

Part Overview

The ACML-0201-800-T is a ferrite bead manufactured by Abracon LLC, designed for electromagnetic interference (EMI) suppression in 0201 (0603 Metric) surface mount applications. This component provides 80 Ohms of impedance at 100 MHz with a maximum current rating of 200mA and 600mOhm DC resistance. The part is currently Active in product status with ROHS3 compliance and unlimited moisture sensitivity level (MSL 1).

Equivalent and substitute parts are identified when design requirements allow tolerance in impedance values, DC resistance characteristics, or current ratings while maintaining the same physical package, mounting type, and operating temperature range.

Substitute Part Grouping Explanation

Substitute parts for the ACML-0201-800-T are grouped based on the following substitution criteria:

Primary Substitution Parameters:

Package / Case: 0201 (0603 Metric) — physical compatibility required
Mounting Type: Surface Mount — assembly process compatibility
Operating Temperature: -55°C ~ 125°C — thermal operating range
Impedance @ 100 MHz: 70–80 Ohms — functional impedance tolerance
Current Rating (Max): 200–300mA — current handling capability
DC Resistance (Max): 300–600mOhm — power dissipation characteristics

Parts are considered equivalent when they maintain the same package footprint, operating temperature range, and impedance within the specified tolerance band. Variations in current rating and DC resistance are acceptable when the substitute part meets or exceeds the original specification.

Engineering Selection Recommendations

Direct Impedance Match (80 Ohms @ 100 MHz):

BLM03AG800SN1D (Murata Electronics) — Active status, improved DC resistance (400mOhm vs. 600mOhm), identical current rating
MMZ0603S800CT000 (TDK Corporation) — Active status, superior DC resistance (300mOhm), identical current rating
Z0201C800ASMST (KEMET) — Obsolete status; use only if existing inventory constraints require legacy part compatibility

Impedance Tolerance Range (70–75 Ohms @ 100 MHz):

BLM03AG700SN1D (Murata Electronics) — Active status, lower impedance with improved DC resistance (400mOhm)
BLM03BD750SN1D (Murata Electronics) — Active status, 75 Ohm impedance with enhanced current rating (300mA)
BMC1HY0070AN (TE Connectivity Passive Product) — Active status, 70 Ohm impedance with superior DC resistance (350mOhm) and higher current rating (300mA)
FB060303T-700Y-S (Cal-Chip Electronics, Inc.) — Active status, 70 Ohm impedance with superior DC resistance (350mOhm) and higher current rating (300mA)
MMZ0603Y750CT000 (TDK Corporation) — Active status, 75 Ohm impedance with enhanced current rating (300mA)

All substitute parts maintain the 0201 (0603 Metric) package, surface mount configuration, and -55°C ~ 125°C operating temperature range. Selection should prioritize Active status parts and ROHS3 compliance for new designs.

Frequently Asked Questions (FAQ)

Q: Can BLM03AG800SN1D be used as a direct replacement for ACML-0201-800-T?

A: Yes. Both parts provide 80 Ohms impedance at 100 MHz, support 200mA maximum current, and use the 0201 (0603 Metric) package with identical operating temperature range. BLM03AG800SN1D offers improved DC resistance (400mOhm vs. 600mOhm) and is currently Active in product status.

Q: What is the difference between 70 Ohm and 80 Ohm ferrite beads in this package?

A: Impedance value determines the frequency-dependent attenuation characteristics. 70 Ohm beads provide slightly lower impedance, affecting EMI suppression bandwidth. Selection depends on the specific frequency range requiring suppression in your application. Both values are within the substitution tolerance for this product category.

Q: Why is Z0201C800ASMST listed if it is Obsolete?

A: Z0201C800ASMST is included for reference in cases where existing designs or inventory require legacy part compatibility. For new designs, Active status alternatives such as BLM03AG800SN1D or MMZ0603S800CT000 are recommended.

Q: Are there packaging differences between Cut Tape (CT) and Tape & Reel (TR) options?

A: Cut Tape and Tape & Reel are supply formats only and do not affect component electrical or mechanical specifications. Selection between CT and TR depends on assembly volume and handling requirements, not functional compatibility.

Q: Can I use a 300mA-rated ferrite bead in place of a 200mA-rated part?

A: Yes. A higher current rating indicates the part can handle greater current without exceeding thermal limits. Parts such as BLM03BD750SN1D, BMC1HY0070AN, FB060303T-700Y-S, and MMZ0603Y750CT000 with 300mA ratings are suitable substitutes when current requirements are within their specifications.

Q: What does DC Resistance (DCR) mean in ferrite bead selection?

A: DC Resistance represents the resistive component of the bead at direct current. Lower DCR values (300–350mOhm) result in reduced power dissipation and heat generation compared to higher values (400–600mOhm). Selection depends on power budget and thermal constraints in your circuit.
