EZ-GPS USB GPS Dongle Equivalent & Substitute Parts

Part Overview

The EZ-GPS is an RF transceiver module operating at 1575.42MHz designed for GPS applications with serial interface connectivity. This component is classified as obsolete, necessitating identification of active equivalent parts for ongoing system designs and maintenance applications. The EZ-GPS provides plug-and-play USB GPS functionality with -159dBm sensitivity and operates on 1.8V supply voltage.

Due to its obsolete product status, the EZ-GPS requires substitution with active production alternatives that maintain functional compatibility while meeting current supply chain requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the EZ-GPS is determined by the following critical parameters:

Functional Equivalence: Both the main part and substitute must operate as GPS RF transceivers with identical modulation protocol (GPS).

Frequency Compatibility: The operating frequency must remain within the GPS L1 band specification. The main part operates at 1575.42MHz; the substitute operates at 1.575GHz (1575MHz), which is functionally equivalent within GPS band tolerances.

Sensitivity Matching: Both components maintain -159dBm sensitivity, ensuring equivalent reception performance.

Interface Consideration: The main part uses serial interface while the substitute uses USB interface. This represents a functional upgrade path rather than a direct pin-compatible replacement, as both provide data communication capability for GPS applications.

Supply Voltage: The main part requires 1.8V; the substitute accepts 3V to 5V range. System integration requires voltage regulation adjustment.

Product Status Transition: The substitute (EZ-GPS-G) holds active product status, ensuring continued availability and supply chain support.

Parameter Comparison

Engineering Selection Recommendations

For Direct Substitution: The EZ-GPS-G serves as the active production equivalent to the obsolete EZ-GPS. Both components share identical GPS protocol implementation and sensitivity specifications, establishing functional equivalence.

Integration Requirements: System designs utilizing the EZ-GPS must accommodate the following modifications when transitioning to EZ-GPS-G:

Interface conversion from serial to USB protocol requires firmware or driver-level adaptation.

Power supply modification from 1.8V to 3V–5V operating range necessitates voltage regulation circuit adjustment.

Compliance Advantage: The EZ-GPS-G holds RoHS Compliant certification and REACH Unaffected status, meeting current environmental and regulatory requirements that may not apply to the obsolete EZ-GPS.

Supply Chain Continuity: With 800 units in current inventory and active product status, the EZ-GPS-G ensures long-term component availability for production and maintenance applications.

Frequently Asked Questions (FAQ)

Q: Can EZ-GPS-G directly replace EZ-GPS in existing designs without modification?

A: No. While both components function as GPS transceivers with identical sensitivity, the interface differs (serial vs. USB) and supply voltage requirements differ (1.8V vs. 3V–5V). System integration modifications are required.

Q: What is the frequency difference between EZ-GPS and EZ-GPS-G?

A: EZ-GPS operates at 1575.42MHz; EZ-GPS-G operates at 1.575GHz (1575MHz). Both frequencies fall within the GPS L1 band specification and are functionally compatible for GPS applications.

Q: Does EZ-GPS-G meet current environmental compliance standards?

A: Yes. EZ-GPS-G is RoHS Compliant and REACH Unaffected, meeting current environmental and regulatory requirements for component procurement.
