ACML-0805-800-T Ferrite Bead Equivalent & Substitute Parts

Part Overview

The ACML-0805-800-T is a ferrite bead manufactured by Abracon LLC, designed for electromagnetic interference (EMI) suppression in surface mount applications. This component provides 80 Ohms of impedance at 100 MHz with a maximum current rating of 1A and is housed in a 0805 (2012 Metric) package. The part is currently in active production status. Equivalent and substitute parts may be required due to inventory constraints, supply chain discontinuities, or specific application requirements where alternative impedance values are acceptable within design tolerances.

Substitute Part Grouping Explanation

Substitution of the ACML-0805-800-T is determined by strict adherence to the following critical parameters:

Mandatory Matching Parameters:

• Package / Case: 0805 (2012 Metric)
• Mounting Type: Surface Mount
• Current Rating (Max): 1A
• DC Resistance (Max): 100 mOhm
• Operating Temperature Range: -55°C to 125°C
• Size / Dimension: 0.079" L x 0.049" W (2.00mm x 1.25mm)
• Height (Max): 0.041" (1.05mm)
• Number of Lines: 1

Allowable Variation Parameter:

• Impedance @ Frequency: Substitute parts may vary within the ferrite bead impedance range for 0805 packages, provided all other electrical and mechanical parameters remain constant.

The Z0805C750ASMST from KEMET meets all mandatory matching parameters with an impedance specification of 75 Ohms @ 100 MHz, representing a 6.25% deviation from the primary part's 80 Ohm specification. This variation falls within acceptable tolerance for ferrite bead applications where impedance matching is not critical to circuit function.

Engineering Selection Recommendations

The ACML-0805-800-T is the preferred selection for new designs due to its active product status and continuous manufacturer support. The Z0805C750ASMST substitute is classified as obsolete and should be considered only when the primary part is unavailable and design constraints permit a 5 Ohm impedance reduction (6.25% variance).

Both parts maintain identical compliance certifications: ROHS3 Compliant, REACH Unaffected, and EAR99 classification. Both components support unlimited moisture sensitivity handling (MSL 1), eliminating moisture-related storage and assembly constraints.

The primary distinction between these parts is product lifecycle status. Selection of the obsolete Z0805C750ASMST should be limited to legacy system maintenance or situations where existing inventory is available and circuit performance tolerates the specified impedance variance.

Frequently Asked Questions (FAQ)

Q: Can the Z0805C750ASMST replace the ACML-0805-800-T in all applications?

A: Substitution is mechanically and electrically compatible based on matching package dimensions, current ratings, DC resistance, and operating temperature specifications. The 5 Ohm impedance difference (75 Ohms vs. 80 Ohms) must be evaluated against specific circuit requirements. Applications where ferrite bead impedance is non-critical to EMI suppression performance will tolerate this variance.

Q: What is the significance of the product status difference?

A: The ACML-0805-800-T is in active production, ensuring long-term availability and manufacturer support. The Z0805C750ASMST is obsolete, indicating discontinued production. Obsolete parts carry supply risk and should not be selected for new designs unless existing inventory is available for the entire production run.

Q: Are the packaging formats interchangeable?

A: Both parts use identical 0805 (2012 Metric) surface mount packages with matching dimensions and height specifications. The difference in packaging format (Tape & Reel vs. Cut Tape) affects only procurement and assembly logistics, not component compatibility or performance.

Q: Do both parts meet the same regulatory and compliance standards?

A: Yes. Both the ACML-0805-800-T and Z0805C750ASMST are ROHS3 Compliant, REACH Unaffected, and classified as EAR99 for export control purposes. Both components have MSL 1 rating, requiring no special moisture handling during storage or assembly.

Q: What is the impedance tolerance between these parts?

A: The impedance difference is 5 Ohms absolute (75 Ohms vs. 80 Ohms), representing a 6.25% variance from the primary part specification. This variance is within typical ferrite bead manufacturing tolerances and acceptable for general EMI suppression applications where precise impedance matching is not required.
