FNS.01.1F11 Equivalent & Substitute Parts

Part Overview

The FNS.01.1F11 is a multi-band dome RF antenna manufactured by Taoglas Limited, designed for cellular and navigation applications across 10 frequency bands. This component operates across DCS, GPS, GSM, LTE, PCS, and WCDMA standards with N Type Male panel mount termination and IP67/IP69K ingress protection. The product is currently obsolete, making identification of functionally equivalent alternatives essential for system redesign, legacy support, or component sourcing in applications where this antenna was originally specified.

Substitute Part Grouping Explanation

The TLS.01.1F11 is identified as a substitute for the FNS.01.1F11 based on the following substitution criteria:

Common Manufacturer: Both parts are manufactured by Taoglas Limited, ensuring design consistency and compatibility with existing supply chain documentation.

Shared Frequency Coverage: The TLS.01.1F11 operates across frequency bands that overlap with the FNS.01.1F11, including 829MHz (within 698MHz ~ 960MHz range), 1.575GHz (GPS band), and 2.2GHz (within 1.71GHz ~ 2.7GHz range). This provides coverage for GPS and LTE applications present in the original design.

Identical Termination: Both antennas use N Type Male connectors, eliminating the need for adapter modifications in existing RF circuits.

Equivalent Power Rating: Both components support 100 W maximum power, maintaining system power handling specifications.

Compliance Alignment: Both parts are ROHS3 compliant and REACH unaffected, meeting regulatory requirements for the original application.

Mechanical Compatibility: Both antennas share similar height specifications (3.128" vs 3.134"), allowing for minimal mechanical redesign in panel-mounted installations.

Parameter Comparison

Engineering Selection Recommendations

The TLS.01.1F11 is an active product from the same manufacturer, providing a viable path forward from the obsolete FNS.01.1F11. Both components maintain ROHS3 compliance and identical power handling specifications, supporting regulatory continuity in system designs.

The primary engineering consideration is application scope: the FNS.01.1F11 supports 10 frequency bands across DCS, GSM, PCS, and WCDMA standards in addition to GPS and LTE, while the TLS.01.1F11 is optimized for GPS and LTE applications only. Systems requiring full legacy band support (DCS, GSM, PCS, WCDMA) will require alternative component selection or multi-antenna configurations.

The mounting type transition from panel mount to base mount requires mechanical redesign of antenna installation points. The antenna type change from dome to whip/straight may affect form factor and installation envelope considerations in space-constrained applications.

Both components provide equivalent N Type Male termination, eliminating RF connector modifications. The ingress protection specification decreases from IP67/IP69K to IP67, which may impact suitability in high-pressure wash or submersion environments.

Frequently Asked Questions (FAQ)

Q: Can the TLS.01.1F11 directly replace the FNS.01.1F11 without modifications?

A: Direct replacement requires evaluation of three factors: (1) application frequency bands—if your system uses DCS, GSM, or PCS bands, the TLS.01.1F11 does not provide coverage; (2) mounting configuration—the transition from panel mount to base mount requires mechanical redesign; (3) environmental ingress protection—if IP69K rating is required, the TLS.01.1F11's IP67 rating may be insufficient.

Q: What frequency bands does the TLS.01.1F11 cover compared to the FNS.01.1F11?

A: The TLS.01.1F11 covers 829MHz, 1.575GHz (GPS), and 2.2GHz, providing overlap with the FNS.01.1F11's GPS and LTE bands. The FNS.01.1F11 additionally supports DCS (750.5MHz, 860MHz), GSM (880MHz ~ 960MHz), PCS (1.795GHz, 1.92GHz, 2.045GHz), and WCDMA (1.92GHz ~ 2.17GHz) bands not covered by the TLS.01.1F11.

Q: Are the RF connectors compatible between these two antennas?

A: Yes. Both the FNS.01.1F11 and TLS.01.1F11 use N Type Male termination, eliminating the need for connector adapters or RF circuit modifications.

Q: What is the impact of changing from dome to whip antenna type?

A: Antenna type affects radiation pattern, form factor, and installation profile. The dome design of the FNS.01.1F11 provides omnidirectional coverage in a compact profile, while the whip/straight design of the TLS.01.1F11 offers directional characteristics and a different mechanical footprint. System performance and installation constraints must be evaluated for your specific application.

Q: Are both antennas compliant with current regulatory standards?

A: Yes. Both the FNS.01.1F11 and TLS.01.1F11 are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component manufacturing and use.

Q: What is the difference in ingress protection ratings?

A: The FNS.01.1F11 provides IP67 and IP69K protection, suitable for high-pressure wash and temporary submersion. The TLS.01.1F11 provides IP67 protection only, suitable for dust ingress prevention and temporary immersion but not high-pressure wash environments.
