ECHO26/0.1M/IPEX/S/S/26 Equivalent & Substitute Parts

Part Overview

The ECHO26/0.1M/IPEX/S/S/26 is a 1.575GHz GPS ceramic patch RF antenna manufactured by Siretta Ltd, designed for surface mount applications with U.FL (UMCC) IPEX MHF1 termination. This part is currently obsolete, making identification of functionally equivalent alternatives essential for ongoing system support, design updates, and procurement continuity. The ceramic patch antenna design provides 28dB gain with 1.5 VSWR performance suitable for GPS navigation applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ECHO26/0.1M/IPEX/S/S/26 is determined by the following critical parameters:

• Frequency Compatibility: Center frequency must be 1.575GHz to maintain GPS band alignment
• Termination Type: U.FL (UMCC) IPEX MHF1 connector is mandatory for mechanical and electrical compatibility
• Mounting Configuration: Surface mount requirement must be maintained
• RF Performance: VSWR of 1.5 and gain characteristics must be preserved for system impedance matching
• Series Alignment: ECHO 26 series designation indicates compatible electrical and mechanical specifications

The ECHO26A/0.1M/IPEX/S/S/15 qualifies as a direct substitute based on matching frequency, termination type, mounting method, VSWR, and series designation. The primary distinction is the antenna element type (PCB trace versus ceramic patch) and the inclusion of a 100mm cable with LNA integration in the substitute part.

Parameter Comparison

Engineering Selection Recommendations

The ECHO26A/0.1M/IPEX/S/S/15 is the designated substitute for the obsolete ECHO26/0.1M/IPEX/S/S/26. Selection of this alternative is supported by:

• Product Status: The substitute part maintains active production status, ensuring long-term availability and supply chain continuity
• Electrical Compatibility: Matching frequency (1.575GHz), VSWR (1.5), and RF family (Navigation) ensure equivalent RF performance in GPS applications
• Mechanical Compatibility: Identical termination type (U.FL IPEX MHF1) and surface mount configuration enable direct integration without PCB redesign
• Series Continuity: Both parts belong to the ECHO 26 series, confirming validated electrical and mechanical specifications
• Compliance: Both parts carry appropriate ECCN classifications for their respective configurations

The primary design consideration is the antenna element type transition from ceramic patch to PCB trace, combined with integrated 100mm cable and LNA functionality in the substitute. System-level validation is required to confirm gain and impedance matching performance in the target application.

Frequently Asked Questions (FAQ)

Q: Can the ECHO26A/0.1M/IPEX/S/S/15 be used as a direct replacement for the ECHO26/0.1M/IPEX/S/S/26?

A: Yes. Both parts share identical frequency (1.575GHz), termination type (U.FL IPEX MHF1), mounting configuration (surface mount), VSWR (1.5), and series designation (ECHO 26). The substitute is actively produced and maintains GPS navigation band compatibility.

Q: What is the difference between the ceramic patch and PCB trace antenna elements?

A: The original part uses a ceramic patch element, while the substitute uses a PCB trace element. Both are designed for 1.575GHz GPS applications with 1.5 VSWR. The PCB trace variant includes integrated 100mm cable and LNA functionality not present in the ceramic patch version.

Q: Are the connector types identical?

A: Yes. Both parts use U.FL (UMCC) IPEX MHF1 termination, ensuring mechanical and electrical compatibility without connector adaptation.

Q: What is the impact of the integrated LNA in the substitute part?

A: The ECHO26A/0.1M/IPEX/S/S/15 includes an integrated Low Noise Amplifier (LNA) and 100mm cable assembly. This represents a functional enhancement compared to the passive ceramic patch antenna. System integration must account for this additional active component.

Q: Are there packaging differences between these parts?

A: The original part is supplied without specified packaging. The substitute part is supplied in bag packaging. Verify packaging requirements for your procurement and assembly processes.

Q: What certifications apply to each part?

A: The original part carries ECCN EAR99 classification. The substitute part carries ECCN 7A994 classification. Verify compliance requirements for your end-use application and export jurisdiction.
