LEA-6T-2-074 Equivalent & Substitute Parts

Part Overview

The LEA-6T-2-074 is an RF receiver module manufactured by u-blox, designed for GPS positioning applications. This 28-SMD surface mount module integrates Galileo, GLONASS, and GPS reception capabilities with a sensitivity of -160dBm and a maximum data rate of 12Mbps. The module operates across a supply voltage range of 2.7V to 3.6V and supports multiple data interfaces including I2C, SPI, UART, and USB.

The LEA-6T-2-074 is currently in Last Time Buy status, indicating that new production has ceased. This necessitates identification of equivalent substitute parts for ongoing design requirements and procurement planning.

Engineering Selection Recommendations

LEA-F9T-20B is suitable for applications requiring multi-frequency GNSS reception with enhanced sensitivity. This part is in Active product status and includes RoHS3 compliance, REACH unaffected status, and ECCN 7A994 classification. The LEA-F9T-20B supports BeiDou, Galileo, GLONASS, GNSS, and GPS protocols across six frequency bands (1.176GHz, 1.207GHz, 1.227GHz, 1.561GHz, 1.575GHz, 1.602GHz) with -167dBm sensitivity. Moisture Sensitivity Level is rated at 4 (72 Hours).

LEA-M8T-1 is suitable for navigation applications requiring multi-constellation GNSS support including QZSS. This part is in Active product status with identical compliance certifications (RoHS3, REACH unaffected, ECCN 7A994). The LEA-M8T-1 integrates the UBX-M8030 IC and supports BeiDou, Galileo, GLONASS, GNSS, GPS, and QZSS protocols across three frequency bands (1.561GHz, 1.575GHz, 1.602GHz) with -167dBm sensitivity. Moisture Sensitivity Level is rated at 4 (72 Hours).

Both substitute parts maintain electrical and mechanical compatibility with the LEA-6T-2-074 while offering extended protocol support and improved sensitivity. Selection between these alternatives depends on specific application requirements for frequency band coverage and constellation support.

Frequently Asked Questions (FAQ)

Q: Can LEA-F9T-20B or LEA-M8T-1 be used as direct replacements for LEA-6T-2-074?

A: Both parts maintain the same 28-SMD package, supply voltage range (2.7V ~ 3.6V), data interfaces (I2C, SPI, UART, USB), operating temperature range (-40°C ~ 85°C), and maximum data rate (12Mbps). Electrical and mechanical compatibility is maintained. However, firmware and software integration should be evaluated based on specific application requirements.

Q: What are the key differences between LEA-F9T-20B and LEA-M8T-1?

A: LEA-F9T-20B operates across six frequency bands (1.176GHz, 1.207GHz, 1.227GHz, 1.561GHz, 1.575GHz, 1.602GHz) and supports BeiDou, Galileo, GLONASS, GNSS, and GPS. LEA-M8T-1 operates across three frequency bands (1.561GHz, 1.575GHz, 1.602GHz) and adds QZSS support to the constellation options. Both achieve -167dBm sensitivity compared to the LEA-6T-2-074's -160dBm.

Q: Are there packaging differences between these parts?

A: All three parts use 28-SMD Module packaging and are supplied in Tape & Reel (TR) format for the substitute parts. The LEA-6T-2-074 packaging format was not specified in the provided data. All parts are surface mount compatible with identical footprints.

Q: What compliance certifications apply to the substitute parts?

A: Both LEA-F9T-20B and LEA-M8T-1 are RoHS3 compliant, REACH unaffected, and classified under ECCN 7A994 with HTSUS code 8526.91.0020. Moisture Sensitivity Level for both is rated at 4 (72 Hours).

Q: How does sensitivity improvement affect system performance?

A: The substitute parts provide -167dBm sensitivity compared to the LEA-6T-2-074's -160dBm, representing a 7dBm improvement. This enhanced sensitivity supports reception in weaker signal environments and may improve acquisition time and tracking performance in challenging conditions.
