OUTSIDE-WSMA RF Antenna Module Equivalent & Substitute Parts

Part Overview

The OUTSIDE-WSMA is a multi-band RF antenna module manufactured by RF Solutions, designed for cellular and wireless applications operating across five frequency bands: 433MHz, 868MHz, 900MHz, 1.8GHz, and 1.9GHz. The module features a 3dB gain, SMA male termination, and 3-meter cable assembly with chassis mount configuration for GSM and UMTS systems.

This part is classified as Obsolete. Identifying equivalent and substitute components is necessary to maintain system functionality, ensure design continuity, and support ongoing production or field replacement requirements where original inventory becomes depleted.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the OUTSIDE-WSMA is determined by the following critical parameters:

Frequency Coverage: The substitute part must support the primary operating bands of 433MHz, 868MHz, 900MHz, 1.8GHz, and 1.9GHz used in GSM and UMTS applications.

Termination Type: Both the main part and substitute must feature SMA Male connectors to ensure mechanical and electrical compatibility with existing RF interfaces.

Gain Characteristics: The substitute part must deliver comparable RF performance within the operating frequency bands.

Compliance Requirements: The substitute must maintain RoHS compliance and appropriate export classification (ECCN) for the intended application.

Mounting and Form Factor: Physical compatibility with chassis mount or equivalent installation methods is required.

The identified substitute part GA.110.101111 from Taoglas Limited satisfies these criteria through its multi-band frequency coverage spanning 698MHz to 3.5GHz, which encompasses all five primary bands of the OUTSIDE-WSMA, SMA Male termination, and RoHS3 compliance status.

Parameter Comparison

Engineering Selection Recommendations

Compliance and Regulatory Status: The OUTSIDE-WSMA is RoHS Compliant with EAR99 export classification. The substitute GA.110.101111 is ROHS3 Compliant with ECCN 7A994 classification. Both parts meet environmental compliance requirements; however, the different ECCN classification requires verification against specific export control regulations for the intended destination market.

Product Lifecycle Consideration: The OUTSIDE-WSMA is classified as Obsolete, making GA.110.101111 the appropriate active alternative. The substitute is currently in production with 1722 units in stock, ensuring supply chain continuity.

Frequency Band Coverage: GA.110.101111 provides complete coverage of all five primary frequency bands (433MHz, 868MHz, 900MHz, 1.8GHz, 1.9GHz) required for GSM and UMTS applications, with extended coverage to 3.5GHz supporting additional wireless standards.

Connector Compatibility: Both parts feature SMA Male termination, ensuring direct RF interface compatibility with existing system designs.

Physical Integration Differences: The substitute employs a magnetic mounting base and whip antenna configuration, differing from the chassis mount module design of the original part. System integration may require mechanical redesign or mounting adapter consideration.

Cable Assembly: The substitute includes a 1-meter cable versus the 3-meter cable of the original part. Extended cable runs may require external RF cable extensions to maintain system geometry.

Frequently Asked Questions (FAQ)

Q: Can GA.110.101111 directly replace OUTSIDE-WSMA in existing designs?

A: GA.110.101111 provides electrical compatibility through identical SMA Male termination and complete frequency band coverage. However, physical integration differs due to magnetic mounting versus chassis mount configuration. Mechanical redesign or mounting adaptation may be necessary.

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

A: Both parts support GSM and UMTS applications with SMA Male connectors. GA.110.101111 extends frequency coverage to 3.5GHz and provides variable gain across eight bands (1.8dBi to 3.9dBi) compared to the fixed 3dB gain of OUTSIDE-WSMA. The substitute is rated for 50W maximum power.

Q: Are there export control implications for using GA.110.101111?

A: Yes. OUTSIDE-WSMA carries ECCN EAR99 classification, while GA.110.101111 carries ECCN 7A994. Verify the applicable ECCN classification against export control requirements for your specific destination market and application.

Q: Does the 1-meter cable of GA.110.101111 create system limitations?

A: The substitute includes a shorter 1-meter cable compared to the 3-meter cable of the original part. If extended cable runs are required, external RF cable extensions with appropriate impedance matching must be incorporated into the system design.

Q: What is the MSL rating difference, if any?

A: Both parts carry MSL Rating 1 (Unlimited), indicating identical moisture sensitivity levels and storage requirements.

Q: Are both parts RoHS compliant?

A: Yes. OUTSIDE-WSMA is RoHS Compliant, and GA.110.101111 is ROHS3 Compliant. Both meet environmental compliance standards; the substitute meets the current RoHS3 specification.
