Key Parameters

Substitute Part Grouping Explanation

The ALPHA1/2.5M/SMAM/S/S/1 has been identified with one direct substitute: ALPHA10/2.5M/SMAM/S/S/20.

Substitution is valid based on the following matching parameters:

• Connector Type: SMA Male termination on both parts
• Mounting Method: Adhesive mounting on both parts
• Manufacturer: Both manufactured by Siretta Ltd
• Frequency Band: Both operate in the 2.4GHz ~ 2.5GHz range
• Antenna Configuration: Blade antenna type on both parts

The ALPHA10 series represents an active product line with current manufacturing status, providing continuity for applications previously served by the obsolete ALPHA1 series.

Parameter Comparison

Engineering Selection Recommendations

The ALPHA10/2.5M/SMAM/S/S/20 is the designated substitute for the obsolete ALPHA1/2.5M/SMAM/S/S/1. Both components share identical connector type (SMA Male), mounting method (adhesive), frequency band (2.4GHz ~ 2.5GHz), and antenna configuration (blade type).

The ALPHA10 series maintains active product status with current manufacturing support. The substitute part provides documented electrical performance specifications (3dBi gain, 1.5 VSWR) and is ROHS3 compliant, meeting modern regulatory requirements. Both parts carry EAR99 export classification.

Selection of the ALPHA10/2.5M/SMAM/S/S/20 is appropriate for applications requiring direct form, fit, and functional compatibility with the obsolete ALPHA1 series.

Frequently Asked Questions (FAQ)

Q: Why is the ALPHA1/2.5M/SMAM/S/S/1 no longer available?

A: The ALPHA1/2.5M/SMAM/S/S/1 has reached end-of-life status and is classified as obsolete. Siretta Ltd has transitioned this product line to the active ALPHA10 series.

Q: Can the ALPHA10/2.5M/SMAM/S/S/20 be used as a direct replacement?

A: Yes. Both parts feature SMA Male connectors, adhesive mounting, and operate across the 2.4GHz ~ 2.5GHz frequency band with identical blade antenna configuration.

Q: What are the key electrical differences between these parts?

A: The ALPHA10 substitute provides specified performance metrics: 3dBi gain and 1.5 VSWR. The original ALPHA1 part specifications for these parameters were not documented in available data.

Q: Are there packaging differences?

A: The ALPHA10/2.5M/SMAM/S/S/20 is supplied in bulk packaging. Original packaging specifications for the ALPHA1 part are not available.

Q: Does the substitute meet current compliance standards?

A: The ALPHA10/2.5M/SMAM/S/S/20 is ROHS3 compliant and REACH unaffected, meeting current regulatory requirements. Both parts carry EAR99 export classification.

Q: What is the physical height of the substitute antenna?

A: The ALPHA10/2.5M/SMAM/S/S/20 has a maximum height of 0.157 inches (4.00mm).
