LEA-6R-0 Equivalent & Substitute Parts Reference

Part Overview

The LEA-6R-0 is an RF receiver module manufactured by u-blox, designed for multi-constellation GNSS applications including Galileo, GLONASS, and GPS positioning. This module operates with a sensitivity of -162dBm and supports multiple data interfaces (I2C, SPI, UART, USB) for integration into embedded systems. The LEA-6R-0 is classified as obsolete, making identification of functionally compatible substitute components essential for ongoing system support, redesigns, and new production requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the LEA-6R-0 is determined by the following critical parameters:

Electrical Compatibility:

• Supply voltage range: 2.7V ~ 3.6V (must match or be compatible)
• Data interfaces: I2C, SPI, UART, USB (substitute must support these protocols)
• Operating temperature range: -40°C ~ 85°C (must meet or exceed)

Functional Compatibility:

• GNSS constellation support: Galileo, GLONASS, GPS (substitute must support these constellations)
• Receiver sensitivity: -162dBm baseline (substitute sensitivity must be equal or better)

Physical Compatibility:

• Mounting type: Surface Mount
• Package form factor: Module-based design

The ZED-F9R-01B qualifies as a substitute based on matching electrical parameters (2.7V ~ 3.6V supply, -40°C ~ 85°C operating range), supporting all required data interfaces (I2C, SPI, UART, USB), and providing enhanced GNSS constellation support (BeiDou, Galileo, GLONASS, GNSS, GPS) with improved sensitivity (-160dBm) and higher data rate capability (921.6kbps).

Parameter Comparison

Engineering Selection Recommendations

For LEA-6R-0 Replacement:

The ZED-F9R-01B is the manufacturer-recommended substitute for the obsolete LEA-6R-0. Both components are manufactured by u-blox and share identical electrical specifications (2.7V ~ 3.6V supply voltage, -40°C ~ 85°C operating temperature range, and all four data interface protocols: I2C, SPI, UART, USB).

Compliance Considerations:

The ZED-F9R-01B carries active product status with ROHS3 compliance and REACH unaffected designation, making it suitable for new designs and production environments with current regulatory requirements. The LEA-6R-0, being obsolete, is no longer supported by the manufacturer.

Performance Enhancement:

The ZED-F9R-01B provides improved receiver sensitivity (-160dBm versus -162dBm) and expanded GNSS constellation support, including BeiDou in addition to Galileo, GLONASS, and GPS. The specified data rate of 921.6kbps enables higher-throughput applications.

Package Transition:

The primary physical difference is the package change from 28-SMD to 54-LGA (22x17). This requires PCB layout modification and re-qualification of the module footprint. The increased pin count and different form factor necessitate design review before implementation.

Frequently Asked Questions (FAQ)

Q: Can the ZED-F9R-01B directly replace the LEA-6R-0 without design changes?

A: Electrical and protocol compatibility is confirmed (supply voltage, operating temperature, data interfaces). However, the package change from 28-SMD to 54-LGA (22x17) requires PCB layout modification. Direct socket substitution is not possible.

Q: What are the key electrical compatibility factors?

A: Supply voltage (2.7V ~ 3.6V), operating temperature range (-40°C ~ 85°C), and data interface support (I2C, SPI, UART, USB) are identical between both components. No power supply or interface circuit redesign is required.

Q: Does the ZED-F9R-01B support the same GNSS constellations?

A: The ZED-F9R-01B supports all constellations required by the LEA-6R-0 (Galileo, GLONASS, GPS) plus additional support for BeiDou and GNSS. This represents functional enhancement with no loss of capability.

Q: What is the impact of the sensitivity difference (-162dBm vs -160dBm)?

A: The ZED-F9R-01B sensitivity of -160dBm is within 2dBm of the LEA-6R-0 specification. This represents equivalent performance for practical GNSS receiver applications.

Q: Are there compliance or certification differences?

A: The ZED-F9R-01B is ROHS3 compliant with MSL rating 4 (72 Hours) and REACH unaffected status. The LEA-6R-0 compliance specifications are not provided. The ZED-F9R-01B meets current regulatory requirements for new production.

Q: What is the data rate specification difference?

A: The ZED-F9R-01B specifies 921.6kbps maximum data rate. The LEA-6R-0 data rate is not specified in available documentation. The ZED-F9R-01B provides defined throughput capability for high-frequency update applications.
