LEA-6T-2 Equivalent & Substitute Parts

Part Overview

The LEA-6T-2 is an RF receiver module manufactured by u-blox, designed for GPS positioning applications. It operates across Galileo, GLONASS, and GPS frequency bands with a sensitivity of -162dBm and supports multiple data interfaces including I2C, SPI, UART, and USB. The module is housed in a 28-SMD surface mount package and operates within a supply voltage range of 2.7V to 3.6V across an extended temperature range of -40°C to 85°C.

The LEA-6T-2 is currently in Last Time Buy status, indicating end-of-life production. Identifying equivalent and substitute parts is necessary to ensure design continuity and maintain component availability for new production runs and system updates.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the LEA-6T-2 are qualified based on the following critical parameters that determine functional and mechanical compatibility:

Core Compatibility Criteria:

• Manufacturer: u-blox (same manufacturer ensures design consistency and protocol compatibility)
• Package / Case: 28-SMD Module (identical physical form factor and pin configuration)
• Mounting Type: Surface Mount (same PCB assembly process)
• Data Interface: I2C, SPI, UART, USB (identical communication protocols)
• Voltage - Supply: 2.7V ~ 3.6V (identical power supply requirements)
• Operating Temperature: -40°C ~ 85°C (identical thermal operating range)
• Antenna Connector: Not Included (same antenna integration approach)

Substitution Logic: The LEA-F9T-20B and LEA-M8T-1 meet all core compatibility criteria. Both are u-blox GNSS receiver modules in 28-SMD packages with identical electrical interfaces, power requirements, and thermal specifications. These parts represent active product alternatives with enhanced capabilities, including support for additional GNSS constellations (BeiDou, QZSS) and improved sensitivity ratings.

Parameter Comparison

Engineering Selection Recommendations

LEA-F9T-20B is recommended as the primary substitute for new designs. This part is in Active product status with full manufacturing support. It provides improved sensitivity (-167dBm versus -162dBm), extended GNSS constellation support including BeiDou, and maintains identical electrical and mechanical interfaces. The part carries ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements.

LEA-M8T-1 is recommended as a secondary substitute option. This part is also in Active product status with robust inventory availability (1799 Pcs). It supports an additional GNSS constellation (QZSS) and delivers equivalent sensitivity performance. The part meets identical compliance and regulatory standards.

Both substitute parts maintain full compatibility with existing LEA-6T-2 designs through identical package geometry, pin configuration, power supply requirements, and data interface protocols. Selection between LEA-F9T-20B and LEA-M8T-1 should be based on specific application requirements for GNSS constellation support and inventory availability.

Frequently Asked Questions (FAQ)

Q: Can LEA-F9T-20B or LEA-M8T-1 be used as direct replacements for LEA-6T-2 in existing designs?

A: Yes. Both substitute parts maintain identical package geometry (28-SMD), pin configuration, power supply voltage (2.7V ~ 3.6V), operating temperature range (-40°C ~ 85°C), and data interface protocols (I2C, SPI, UART, USB). No PCB redesign or firmware modification is required for basic functionality. However, firmware updates may be necessary to utilize enhanced GNSS constellation capabilities.

Q: What are the key differences between the substitute parts?

A: LEA-F9T-20B supports BeiDou, Galileo, GLONASS, GNSS, and GPS constellations with a maximum data rate of 12Mbps. LEA-M8T-1 adds QZSS constellation support to the same set. Both provide improved sensitivity (-167dBm) compared to the LEA-6T-2 (-162dBm). LEA-M8T-1 has higher inventory availability.

Q: Are there packaging differences between these parts?

A: The LEA-6T-2 is supplied in standard packaging. LEA-F9T-20B is supplied in Tape & Reel (TR) packaging. LEA-M8T-1 is also supplied in Tape & Reel (TR) packaging. All three parts use identical 28-SMD module form factors suitable for automated assembly.

Q: What compliance certifications apply to the substitute parts?

A: LEA-F9T-20B carries ROHS3 compliance, REACH unaffected status, and ECCN 7A994 classification. LEA-M8T-1 carries equivalent compliance with ECCN 7A994 classification. Both parts have Moisture Sensitivity Level (MSL) rating of 4 (72 Hours).

Q: Why is the LEA-6T-2 in Last Time Buy status?

A: Last Time Buy status indicates the manufacturer has discontinued active production. The LEA-F9T-20B and LEA-M8T-1 represent the current generation of u-blox GNSS receiver modules with enhanced capabilities and ongoing manufacturing support.
