GPDF.47.8.A.02 Equivalent & Substitute Parts

Part Overview

The GPDF.47.8.A.02 is a dual-band ceramic patch RF antenna manufactured by Taoglas Limited, designed for GPS and Galileo navigation applications. Operating at 1.227GHz and 1.575GHz, this component provides gains of 0.04dBi and 4.23dBi respectively, with pin termination and adhesive mounting. The product is currently obsolete, necessitating identification of active substitute components that maintain functional compatibility for GPS/Galileo receiver systems.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the GPDF.47.8.A.02 is determined by the following critical parameters:

Frequency Coverage: The substitute must support the GPS L1 frequency band (1.575GHz) and Galileo E2 frequency band (1.227GHz) to maintain receiver compatibility.

Antenna Type: Ceramic patch construction is required to preserve RF performance characteristics and form factor constraints.

Termination Type: Pin termination is mandatory for PCB integration compatibility.

Navigation Standard Support: The substitute must support GPS and Galileo applications as minimum requirements.

Compliance & Certification: RoHS3 compliance and MSL rating must be maintained for manufacturing and environmental requirements.

The GPDF5012.A qualifies as a substitute because it operates across the required frequency bands (1.227GHz and 1.575GHz are included within its 5-band coverage), maintains ceramic patch antenna construction, uses pin termination, and meets all compliance requirements. The primary design difference is mounting type (surface mount vs. adhesive) and expanded frequency support for additional navigation standards.

Parameter Comparison

Engineering Selection Recommendations

The GPDF5012.A is an active substitute for the obsolete GPDF.47.8.A.02. Both components maintain ROHS3 compliance and unlimited MSL rating, ensuring compatibility with standard manufacturing and storage requirements.

The substitute provides expanded frequency coverage supporting Beidou, GLONASS, and additional GNSS bands beyond the original GPS and Galileo support. This extended capability does not compromise GPS/Galileo functionality, as the required 1.227GHz and 1.575GHz bands are fully supported.

Design integration requires evaluation of two factors: mounting type transition from adhesive to surface mount, and height increase from 8.00mm to 12.50mm. These mechanical differences necessitate PCB layout and enclosure clearance verification during implementation.

Frequently Asked Questions (FAQ)

Q: Can the GPDF5012.A directly replace the GPDF.47.8.A.02 in existing designs?

A: Functional RF compatibility is maintained for GPS and Galileo reception. However, mounting type differs (surface mount vs. adhesive), and the component height increases from 8.00mm to 12.50mm. PCB layout and mechanical clearance must be re-evaluated.

Q: Why does the substitute support more frequency bands?

A: The GPDF5012.A is designed for multi-constellation GNSS applications. The additional bands (Beidou, GLONASS) do not interfere with GPS and Galileo operation and provide enhanced positioning capability in systems that support these standards.

Q: Are compliance certifications equivalent?

A: Yes. Both components are ROHS3 compliant, REACH unaffected, and carry MSL rating 1 (unlimited). Regulatory and environmental requirements are maintained.

Q: What is the impact of the increased antenna height?

A: The height increase from 8.00mm to 12.50mm affects mechanical integration. Enclosure design, PCB stack-up, and component clearance must be verified to ensure the substitute fits within existing form factor constraints.

Q: Is pin termination identical between both components?

A: Yes. Both components use pin termination for PCB integration. Footprint compatibility depends on pin pitch and layout, which should be verified against the specific PCB design.
