FGR2-PE RF Transceiver Module Equivalent & Substitute Parts

Part Overview

The FGR2-PE is an RF transceiver module manufactured by FreeWave Technologies, operating in the 902MHz to 928MHz frequency band with GFSK modulation. This module is classified as obsolete product status. Due to its obsolete designation, identifying equivalent and substitute parts is necessary to maintain system functionality and ensure continued availability for applications requiring 900MHz band RF communication with comparable electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the FGR2-PE is determined by the following critical parameters:

Frequency Compatibility: The substitute part must operate within the 902MHz to 928MHz ISM band to maintain regulatory compliance and system interoperability.

Sensitivity and Power Output: The substitute must maintain receiver sensitivity at -108dBm and support comparable RF output power to ensure link budget equivalence.

Supply Voltage Range: The substitute must accept 6V to 30V supply voltage to integrate with existing power distribution systems.

Serial Interface Support: The substitute must provide Ethernet and Serial connectivity options to maintain compatibility with host system interfaces.

Operating Temperature Range: The substitute must function across -40°C to 75°C to support the same environmental deployment scenarios.

The Z9-PE2-GREY substitute part meets these critical parameters while offering active product status and enhanced data rate capability through FHSS modulation protocol.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The FGR2-PE is designated obsolete, making long-term availability and supply chain continuity uncertain. The Z9-PE2-GREY maintains active product status with FreeWave Technologies, ensuring ongoing manufacturing support and component availability.

Compliance and Certification: The FGR2-PE is RoHS non-compliant. Selection of the Z9-PE2-GREY substitute provides access to a current product line with potential for improved environmental compliance standards, subject to manufacturer documentation verification.

Frequency and Sensitivity Alignment: Both parts operate identically within the 902MHz to 928MHz band with -108dBm receiver sensitivity, supporting equivalent RF link performance in 900MHz ISM band applications.

Power Supply Integration: Identical 6V to 30V supply voltage range ensures direct integration with existing power distribution architectures without modification.

Interface Compatibility: The Z9-PE2-GREY provides RJ-45 connector and RS-232/485 serial interfaces, maintaining compatibility with standard industrial communication protocols used in the FGR2-PE application environment.

Modulation Protocol Difference: The Z9-PE2-GREY employs FHSS modulation versus the FGR2-PE GFSK modulation. This represents a functional enhancement providing frequency hopping spread spectrum capability, which may require firmware or protocol stack updates in host systems.

Frequently Asked Questions (FAQ)

Q: Can the Z9-PE2-GREY directly replace the FGR2-PE without any modifications?

A: Both parts share identical frequency range (902MHz ~ 928MHz), sensitivity (-108dBm), and supply voltage (6V ~ 30V). However, the modulation protocol differs (FHSS versus GFSK). Direct physical replacement is possible; protocol compatibility with host systems requires verification.

Q: What is the primary reason for substitution?

A: The FGR2-PE is obsolete product status. The Z9-PE2-GREY is an active product from the same manufacturer, ensuring supply chain continuity and ongoing technical support.

Q: Are the serial interfaces compatible?

A: The FGR2-PE supports Ethernet and Serial interfaces. The Z9-PE2-GREY provides RJ-45 connector and RS-232/485 serial interfaces. These are compatible with standard industrial communication systems.

Q: Does the Z9-PE2-GREY support the same operating temperature range?

A: The FGR2-PE operates from -40°C to 75°C. The Z9-PE2-GREY operating temperature range is not specified in the provided data. Temperature range verification is required before deployment in extreme environment applications.

Q: What is the difference between GFSK and FHSS modulation?

A: GFSK (Gaussian Frequency Shift Keying) is a continuous phase modulation scheme. FHSS (Frequency Hopping Spread Spectrum) is a spread spectrum technique that changes carrier frequency during transmission. FHSS provides enhanced interference immunity and security characteristics.

Q: Is the packaging identical?

A: Both parts are supplied as modules. The FGR2-PE packaging is listed as dash (-), while the Z9-PE2-GREY is supplied in bulk packaging. Physical form factor compatibility should be confirmed for mechanical integration.

Q: What is the data rate difference?

A: The FGR2-PE specifies 153.6kbps data rate. The Z9-PE2-GREY specifies 100Mbps maximum data rate. This represents a significant increase in throughput capability with the substitute part.
