EXC806SM RF Antenna Equivalent & Substitute Parts

Part Overview

The EXC806SM is a 836MHz Bluetooth and Wi-Fi whip antenna manufactured by TE Connectivity Laird, featuring a straight configuration with SMA Male connector termination. This component operates across the 806MHz to 866MHz frequency band within the UHF spectrum and is rated for 50W maximum power handling.

The EXC806SM carries an Obsolete product status. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production or field replacement requirements for systems utilizing this antenna.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the EXC806SM is determined by the following critical parameters:

Mandatory Compatibility Criteria:

• Termination type: SMA Male connector
• Frequency group: UHF (300MHz ~ 1GHz)
• Mounting type: Connector Mount
• Antenna configuration: Whip type

Performance Parameters:

• Operating frequency range overlap or adjacency
• VSWR specification compatibility
• Maximum power rating sufficient for application requirements

The substitute part TI.19.2113 (Taoglas Limited) meets the mandatory connector and mounting requirements. Both parts operate within the UHF frequency group with SMA Male termination and connector-based mounting. However, the frequency bands differ: EXC806SM operates at 836MHz (806–866MHz range), while TI.19.2113 operates at 915MHz (902–928MHz range). These frequency bands are adjacent within the ISM spectrum allocation and share common application domains (Bluetooth and Wi-Fi).

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The EXC806SM is classified as Obsolete. The TI.19.2113 carries Active product status, indicating ongoing manufacturer support, availability, and compliance maintenance.

Compliance and Certification: Both parts satisfy RoHS requirements. The EXC806SM is RoHS Compliant; the TI.19.2113 is ROHS3 Compliant. The TI.19.2113 additionally carries REACH Unaffected status, providing regulatory clarity for European market applications.

Electrical Performance Differences: The TI.19.2113 exhibits a higher VSWR (1.9 versus 1.5), indicating slightly reduced impedance matching efficiency. The maximum power rating of TI.19.2113 is 10W, compared to 50W for the EXC806SM. Applications requiring the full 50W power handling capability cannot use the TI.19.2113 as a direct substitute.

Physical Form Factor: The TI.19.2113 is significantly taller (389.00mm versus 116.84mm) and features a tilt configuration rather than straight orientation. Space constraints and mounting geometry must be evaluated for mechanical compatibility.

Frequency Band Alignment: The 915MHz center frequency of TI.19.2113 is offset from the 836MHz center frequency of EXC806SM. Both operate within adjacent ISM bands suitable for Bluetooth and Wi-Fi applications. Frequency-specific impedance matching and antenna tuning in the end application must be verified.

Frequently Asked Questions (FAQ)

Q: Can the TI.19.2113 directly replace the EXC806SM in all applications?

A: No. The TI.19.2113 differs in frequency band (915MHz versus 836MHz), maximum power rating (10W versus 50W), physical height (389.00mm versus 116.84mm), and antenna orientation (tilt versus straight). Applications requiring 50W power handling or specific 836MHz tuning cannot use this substitute without circuit redesign and re-qualification.

Q: What does the Obsolete status of the EXC806SM mean for procurement?

A: Obsolete status indicates that TE Connectivity Laird has discontinued manufacturing and support for this part. Existing inventory may be available through authorized distributors, but long-term supply cannot be guaranteed. Alternative parts should be identified for new designs or future production runs.

Q: Are both parts suitable for Bluetooth and Wi-Fi applications?

A: Both parts are specified for Bluetooth and Wi-Fi applications and operate within UHF frequency bands allocated for these standards. However, the EXC806SM targets the 836MHz band, while the TI.19.2113 targets the 915MHz band. Application-specific frequency requirements must be confirmed before substitution.

Q: What is the significance of VSWR differences between these parts?

A: VSWR (Voltage Standing Wave Ratio) measures impedance matching efficiency. The EXC806SM has a VSWR of 1.5, while the TI.19.2113 has a VSWR of 1.9. Lower VSWR indicates better impedance matching and reduced signal reflection. The difference may impact system efficiency and should be evaluated in the context of the complete RF circuit design.

Q: Does the height difference affect mechanical compatibility?

A: Yes. The EXC806SM is 116.84mm tall with a straight configuration, while the TI.19.2113 is 389.00mm tall with a tilt configuration. Enclosure design, mounting clearance, and spatial constraints must be re-evaluated. The tilt feature may provide installation flexibility in some applications but may conflict with existing mechanical designs.

Q: What compliance certifications should I verify for regulatory requirements?

A: Both parts are RoHS compliant. The EXC806SM is RoHS Compliant; the TI.19.2113 is ROHS3 Compliant. The TI.19.2113 additionally carries REACH Unaffected status. Verify that these certifications align with your target market regulatory requirements, particularly for European Union applications.

Q: Can the 10W power rating of TI.19.2113 support high-power applications?

A: No. If your application requires the full 50W power handling capability of the EXC806SM, the TI.19.2113 is not suitable. Exceeding the 10W maximum power rating of the TI.19.2113 will result in component damage and system failure.
