Antenova A10204 RF Antenna 1.575GHz Equivalent & Substitute Parts

Part Overview

The Antenova A10204 is a 1.575GHz GPS chip RF antenna designed for surface mount applications with solder termination. This component operates in the UHF frequency band (1GHz ~ 2GHz) and delivers 0dBi gain with 1.4 VSWR performance. The part is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement continuity. The A10204 is RoHS compliant and carries MSL 1 rating, indicating unlimited moisture tolerance for storage and handling.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Antenova A10204 is determined by the following critical parameters:

Primary Matching Criteria:

• Frequency band alignment at 1.575GHz (GPS L1 band)
• Antenna type classification (chip antenna preferred for form factor compatibility)
• Termination method (solder termination for PCB integration)
• Mounting technology (surface mount for assembly compatibility)
• Physical height constraints (maximum 0.126" / 3.20mm for board clearance)

Secondary Compatibility Factors:

• VSWR performance (1.4 baseline; acceptable range up to 2.0 for GPS applications)
• Return loss specification (-17dB baseline; acceptable minimum -10dB)
• Gain performance (0dBi baseline; acceptable range -0.5dBic to 2.2dBi for GPS reception)
• RoHS and MSL compliance status

The substitute parts listed below meet the primary matching criteria with documented performance within acceptable GPS application tolerances.

Parameter Comparison

Engineering Selection Recommendations

Pulse Electronics W3011A is the primary substitute for direct replacement in existing designs. This part maintains identical solder termination and surface mount characteristics as the A10204, with superior gain performance (2dBi at GPS band) and significantly reduced height (0.043" vs. 0.126"), providing enhanced board layout flexibility. The W3011A is actively manufactured and carries ROHS3 compliance, ensuring long-term supply continuity and regulatory alignment.

Taoglas GP.1575.12.4.A.02 serves as an alternative substitute where design modifications are acceptable. This ceramic patch antenna operates at the same 1.575GHz center frequency with comparable gain (-0.5dBic) but requires design changes: adhesive mounting replaces solder termination, and increased height (0.177") may impact board clearance. The GP.1575.12.4.A.02 is actively produced and ROHS3 compliant, suitable for applications where mounting method flexibility exists.

Both substitute parts maintain GPS application compatibility, unlimited moisture tolerance (MSL 1), and regulatory compliance status. Selection between W3011A and GP.1575.12.4.A.02 depends on PCB assembly process capability and physical space constraints.

Frequently Asked Questions (FAQ)

Q: Can the Pulse Electronics W3011A directly replace the Antenova A10204 without PCB modifications?

A: Yes. The W3011A maintains solder termination and surface mount configuration, requiring no PCB layout changes. The reduced height (0.043" vs. 0.126") provides additional board clearance margin.

Q: What is the key difference between the Taoglas GP.1575.12.4.A.02 and the A10204?

A: The primary difference is mounting method: the GP.1575.12.4.A.02 uses adhesive mounting with pin termination, while the A10204 uses solder termination. The GP.1575.12.4.A.02 also has greater height (0.177" vs. 0.126"). These differences require assembly process and PCB design modifications.

Q: Are all three parts suitable for GPS L1 band applications?

A: Yes. All three parts operate at or near 1.575GHz (GPS L1 center frequency) with frequency ranges or center frequencies within the GPS L1 band specification. Return loss and VSWR performance across all parts support GPS receiver integration.

Q: What is the significance of the MSL 1 rating on these parts?

A: MSL 1 (Unlimited) indicates these components have unlimited shelf life and require no special moisture control during storage or handling. All three parts carry this rating, eliminating moisture-related procurement or storage constraints.

Q: Why is the Antenova A10204 listed as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. The listed substitute parts (W3011A and GP.1575.12.4.A.02) are actively manufactured alternatives that meet the same functional and performance requirements for GPS antenna applications.

Q: Can the W3011A support multi-band GNSS applications?

A: Yes. The W3011A supports Beidou, Galileo, GLONASS, GNSS, and GPS applications across three frequency bands (1.561GHz, 1.5755GHz, 1.602GHz), providing broader satellite constellation compatibility than the single-band A10204.
