ACML-0805-301-T Equivalent & Substitute Parts

Part Overview

The ACML-0805-301-T is a ferrite bead manufactured by Abracon LLC, designed for electromagnetic interference (EMI) suppression in surface mount applications. This component operates at 300 Ohms impedance at 100 MHz with a maximum current rating of 500mA and is housed in a 0805 (2012 Metric) package. The part is currently in active production status and maintains full RoHS3 compliance. Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be achieved across alternative manufacturers while maintaining the same package form factor and operating specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ACML-0805-301-T is determined by the following critical parameters:

Primary Substitution Criteria:

• Package / Case: 0805 (2012 Metric) — mechanical compatibility and PCB footprint alignment
• Impedance @ Frequency: 300 Ohms @ 100 MHz — core electrical performance specification
• Current Rating (Max): minimum 500mA — circuit current handling capability
• DC Resistance (DCR) (Max): maximum 250mOhm — signal integrity and power dissipation
• Operating Temperature: -55°C ~ 125°C — thermal operating range
• Mounting Type: Surface Mount — assembly process compatibility
• RoHS Status: ROHS3 Compliant — regulatory compliance requirement

Substitute parts are grouped into two categories based on impedance alignment:

Category 1: Direct Impedance Match (300 Ohms @ 100 MHz) Parts meeting the exact impedance specification with equivalent or superior current ratings and DCR performance.

Category 2: Near-Impedance Match (330 Ohms @ 100 MHz) Parts with impedance within acceptable tolerance for general EMI suppression applications where the 10% impedance variance does not compromise circuit function.

Parameter Comparison

Engineering Selection Recommendations

Preferred Substitutes (Active Product Status):

FB201209T-301Y-S-1 (Cal-Chip Electronics, Inc.) provides direct impedance equivalence at 300 Ohms @ 100 MHz with identical current rating and superior DCR performance (200mOhm vs. 250mOhm). This part maintains active production status and RoHS compliance, making it the primary alternative for new designs and ongoing production.

BLM21AG331SN1D (Murata Electronics) offers enhanced performance specifications with 330 Ohms impedance, 700mA current rating, and 160mOhm DCR. The 10% impedance increase is acceptable for general EMI suppression where circuit impedance tolerance permits. This part is actively produced and ROHS3 compliant.

Secondary Substitutes (Limited Availability):

MMZ2012S301AT000 (TDK Corporation) matches the 300 Ohms impedance specification with superior current rating (600mA) and DCR (200mOhm). However, this part carries Last Time Buy status, indicating discontinued production. Use only when existing inventory is available and long-term supply is not required.

Not Recommended (Obsolete Status):

Z0805C241ASMST and Z0805C241BSMST (KEMET) are obsolete parts with 240 Ohms impedance, representing a 20% deviation from the specified 300 Ohms. These parts should not be selected for new designs due to discontinued production status and impedance mismatch.

Frequently Asked Questions (FAQ)

Q: Can I use BLM21AG331SN1D as a direct replacement for ACML-0805-301-T?

A: BLM21AG331SN1D is electrically compatible for most EMI suppression applications. The 330 Ohms impedance represents a 10% increase from the specified 300 Ohms. Compatibility depends on circuit design tolerance for impedance variation. Both parts share identical package dimensions (0805 / 2012 Metric), operating temperature range, and RoHS3 compliance. Verify circuit impedance requirements before substitution.

Q: What is the difference between FB201209T-301Y-S-1 and ACML-0805-301-T?

A: Both parts specify 300 Ohms @ 100 MHz impedance and 500mA current rating in 0805 packages. FB201209T-301Y-S-1 offers lower DC resistance (200mOhm vs. 250mOhm), resulting in reduced power dissipation. FB201209T-301Y-S-1 is classified as a Signal Line ferrite bead, while ACML-0805-301-T has no specified filter type designation. Both are RoHS compliant and actively produced.

Q: Why are Z0805C241ASMST and Z0805C241BSMST listed as substitutes if they are obsolete?

A: These parts are included in the substitute list based on the provided input data. However, obsolete status indicates discontinued production. These parts should not be selected for new designs. Use only if existing inventory is available and immediate supply is not critical.

Q: Are all substitute parts compatible with the same PCB footprint?

A: Yes. All listed substitute parts use the 0805 (2012 Metric) package with identical dimensions: 0.079" L x 0.049" W (2.00mm x 1.25mm). Maximum height specifications range from 0.041" to 0.043", all within standard PCB assembly tolerances. Surface mount mounting type is consistent across all parts.

Q: What is the significance of MSL 1 (Unlimited) rating?

A: Moisture Sensitivity Level 1 indicates the component requires no special moisture control during storage or handling. All listed parts carry MSL 1 rating, eliminating moisture-related compatibility concerns during assembly and storage.

Q: Can I substitute based on current rating alone?

A: No. Current rating is one of multiple critical parameters. Impedance @ 100 MHz, DC resistance, package form factor, and operating temperature must all align with circuit requirements. A part with higher current rating but different impedance may not provide equivalent EMI suppression performance.
