Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the LEA-6T-0 are identified based on the following allowable parameters:

• Manufacturer: u-blox (same manufacturer ensures design compatibility and support continuity)
• Package / Case: 28-SMD Module (physical and electrical compatibility with PCB footprint)
• Mounting Type: Surface Mount (assembly process compatibility)
• Voltage - Supply: 2.7V ~ 3.6V (power supply compatibility)
• Data Interface: Must include at least I2C, UART, or USB (functional interface compatibility)
• RoHS Status: ROHS3 Compliant (regulatory compliance alignment)

The LEA-M8T-0 and LEA-F9T-10B meet these substitution criteria while offering enhanced capabilities such as multi-constellation GNSS support and improved sensitivity.

Parameter Comparison

Engineering Selection Recommendations

Both LEA-M8T-0 and LEA-F9T-10B are active products from u-blox and represent valid substitutes for the LEA-6T-0 based on package compatibility, supply voltage alignment, and regulatory compliance.

LEA-M8T-0 maintains identical operating temperature range (-40°C to 85°C) and MSL rating (4, 72 Hours) as the LEA-6T-0, with the addition of I2C interface support alongside SPI, UART, and USB. This part offers multi-constellation GNSS capability with -167dBm sensitivity and documented receiving current of 28mA.

LEA-F9T-10B extends the operating temperature range to -40°C to 105°C and improves MSL rating to 3 (168 Hours), providing enhanced environmental tolerance. This part supports multi-constellation GNSS with -167dBm sensitivity and includes a band pass filter. However, it does not include I2C interface support, offering only SPI, UART, and USB.

Selection between these substitutes depends on specific interface requirements and environmental operating conditions of the target application.

Frequently Asked Questions (FAQ)

Q: Can LEA-M8T-0 or LEA-F9T-10B be used as direct replacements for LEA-6T-0?

A: Both parts share the same 28-SMD Module package, surface mount configuration, and 2.7V to 3.6V supply voltage range. However, interface availability differs. LEA-M8T-0 includes I2C support matching the original part, while LEA-F9T-10B does not. Verify that your design uses only the available interfaces on the selected substitute.

Q: What is the difference in sensitivity between these parts?

A: LEA-6T-0 provides -162dBm sensitivity. Both LEA-M8T-0 and LEA-F9T-10B offer improved -167dBm sensitivity, representing a 5dBm advantage in signal reception capability.

Q: Are there temperature range considerations for substitution?

A: LEA-6T-0 and LEA-M8T-0 operate identically across -40°C to 85°C. LEA-F9T-10B extends this range to -40°C to 105°C. If your application requires operation above 85°C, only LEA-F9T-10B qualifies.

Q: What is the impact of MSL rating differences?

A: LEA-6T-0 and LEA-M8T-0 carry MSL 4 (72 Hours), while LEA-F9T-10B carries MSL 3 (168 Hours). Lower MSL values indicate greater moisture tolerance and longer shelf life before reflow soldering. LEA-F9T-10B provides superior moisture handling characteristics.

Q: Do all substitute parts support the same communication protocols?

A: LEA-6T-0 supports I2C, UART, and USB. LEA-M8T-0 supports I2C, SPI, UART, and USB. LEA-F9T-10B supports SPI, UART, and USB only. If I2C is required, only LEA-M8T-0 maintains full compatibility.

Q: What is the significance of multi-constellation GNSS support in the substitutes?

A: LEA-6T-0 operates on GPS only. Both LEA-M8T-0 and LEA-F9T-10B support BeiDou, Galileo, GLONASS, GNSS, and GPS. This expanded capability provides improved positioning accuracy and availability in diverse geographic regions and signal environments.
