Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ALPHA8/3M/SMAM/S/S/1 is determined by the following critical parameters:

• Antenna type classification (flat bar form factor)
• Frequency band coverage (multiband cellular support across UHF ranges)
• Termination connector type (SMA Male interface)
• Mounting methodology (adhesive-based installation)
• Ingress protection rating (IP66 environmental sealing)
• Gain specification (2dBi performance level)

The substitute part ALPHA8/3M/SMAM/S/S/11 shares the base product designation ALPHA8 with the main part, indicating compatibility within the ALPHA 8 antenna series architecture. Both components are manufactured by Siretta Ltd and maintain the same connector interface and mounting approach.

Parameter Comparison

Engineering Selection Recommendations

The ALPHA8/3M/SMAM/S/S/11 is the designated substitute for the obsolete ALPHA8/3M/SMAM/S/S/1. Both components carry identical ECCN classification (EAR99) and share the same base product architecture within the ALPHA 8 series. The substitute part maintains active product status, ensuring continued availability and manufacturing support.

Selection of the ALPHA8/3M/SMAM/S/S/11 is appropriate for applications requiring replacement of the original ALPHA8/3M/SMAM/S/S/1 component, provided that the specific frequency band requirements, connector interface, and form factor remain consistent with system design parameters.

Frequently Asked Questions (FAQ)

Q: Can the ALPHA8/3M/SMAM/S/S/11 directly replace the ALPHA8/3M/SMAM/S/S/1 in existing designs?

A: Yes. Both components share the ALPHA 8 base series designation, identical SMA Male termination, flat bar antenna type, and adhesive mounting methodology. The substitute part is manufactured by the same supplier and carries the same export classification.

Q: What is the primary difference between these two part numbers?

A: The ALPHA8/3M/SMAM/S/S/1 is obsolete, while the ALPHA8/3M/SMAM/S/S/11 maintains active product status. The substitute part is available in Bag packaging format.

Q: Are the frequency bands identical between both parts?

A: The main part operates across six frequency bands: 850MHz, 868MHz, 900MHz, 1.8GHz, 1.9GHz, and 2.1GHz. Detailed frequency specifications for the substitute part are not provided in the available technical data.

Q: What connector type is used on both antennas?

A: Both the ALPHA8/3M/SMAM/S/S/1 and ALPHA8/3M/SMAM/S/S/11 use SMA Male connectors, ensuring mechanical and electrical compatibility in RF circuit integration.

Q: Is the packaging format interchangeable?

A: The original part has unspecified packaging, while the substitute is supplied in Bag packaging. This difference does not affect component functionality or performance in end-use applications.
