Key Parameters

Substitute Part Grouping Explanation

Substitution of the Z0805C150ASMST is determined by the following critical parameters:

Package Compatibility: The substitute part must use the 0805 (2012 Metric) surface mount package with identical physical dimensions (0.079" L x 0.049" W / 2.00mm x 1.25mm) and maximum height of 0.041" (1.05mm).

Electrical Characteristics: The substitute must be a single-line ferrite bead with impedance at 100 MHz within the acceptable range for the application, maximum DC resistance of 50mOhm, and operating temperature range of -55°C to 125°C.

Current Rating: The substitute must support a minimum current rating of 1.2A to ensure adequate performance in the target circuit.

Regulatory Compliance: The substitute must maintain ROHS3 compliance, MSL 1 rating, and REACH unaffected status to ensure compatibility with manufacturing and environmental requirements.

Product Status: Active product status is preferred to ensure long-term availability and supply chain continuity.

Parameter Comparison

Engineering Selection Recommendations

The ACML-0805-170-T from Abracon LLC is a direct functional substitute for the obsolete Z0805C150ASMST. Both components share identical package dimensions, mounting characteristics, and regulatory compliance certifications. The substitute provides a higher current rating (2A versus 1.2A), which offers additional design margin without introducing compatibility issues. The impedance difference of 2 Ohms (17 Ohms versus 15 Ohms at 100 MHz) remains within acceptable tolerance for single-line ferrite bead applications in signal filtering circuits.

The ACML-0805-170-T maintains active product status, ensuring continued availability and supply chain support. Both parts are ROHS3 compliant, REACH unaffected, and carry MSL 1 ratings, satisfying manufacturing and environmental requirements. The substitute is available in Tape & Reel packaging, suitable for automated assembly processes.

Frequently Asked Questions (FAQ)

Q: Can the ACML-0805-170-T directly replace the Z0805C150ASMST in existing designs?

A: Yes. Both components use the 0805 (2012 Metric) surface mount package with identical physical dimensions and mounting characteristics. The electrical parameters are compatible for signal line filtering applications.

Q: What is the significance of the 2 Ohm impedance difference between the two parts?

A: The impedance difference (15 Ohms versus 17 Ohms at 100 MHz) is within acceptable tolerance for ferrite bead applications. The substitute's slightly higher impedance provides equivalent or improved filtering performance in most signal line circuits.

Q: Does the higher current rating of the ACML-0805-170-T affect compatibility?

A: No. A higher current rating (2A versus 1.2A) provides additional design margin and does not compromise compatibility. The substitute can safely handle the same or greater current loads as the original part.

Q: Are there packaging differences between the two parts?

A: The Z0805C150ASMST is specified with standard packaging, while the ACML-0805-170-T is supplied in Tape & Reel (TR) format. Both are suitable for surface mount assembly; Tape & Reel packaging is standard for automated production environments.

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

A: Yes. Both the Z0805C150ASMST and ACML-0805-170-T are ROHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) moisture sensitivity ratings. They satisfy identical environmental and manufacturing requirements.

Q: Why is product status important when selecting a substitute?

A: The Z0805C150ASMST is obsolete, meaning KEMET no longer manufactures or supports this component. The ACML-0805-170-T is active, ensuring long-term availability, continued manufacturing support, and reliable supply chain access for production and maintenance applications.
