Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LEA-6T-1 is determined by the following critical parameters:

• Supply voltage compatibility (2.7V ~ 3.6V range)
• Surface mount packaging format (28-SMD Module)
• GNSS receiver functionality with GPS protocol support
• Data interface availability (I2C, UART, USB)
• RoHS3 compliance and REACH unaffected status
• Operating temperature range support

The LEA-M8T-1 and LEA-F9T-10B are qualified substitutes based on matching supply voltage, surface mount configuration, and regulatory compliance. Both parts extend GNSS protocol support beyond GPS alone, offering multi-constellation capability while maintaining the same physical form factor and electrical interface standards.

Parameter Comparison

Engineering Selection Recommendations

The LEA-6T-1 is designated Last Time Buy, necessitating transition to active production alternatives. Both LEA-M8T-1 and LEA-F9T-10B maintain full RoHS3 compliance and REACH unaffected status, ensuring regulatory continuity.

The LEA-M8T-1 provides the closest functional alignment with the LEA-6T-1, supporting I2C interface alongside UART and USB. This part extends protocol support to include BeiDou, Galileo, GLONASS, and QZSS constellations while maintaining the -40°C to 85°C operating temperature range. Sensitivity improves to -167dBm.

The LEA-F9T-10B offers extended operating temperature capability (-40°C to 105°C) and improved sensitivity (-167dBm) but removes I2C interface support, providing only SPI, UART, and USB. This configuration suits applications requiring wider thermal operating margins.

Both substitutes are currently in Active product status with established inventory availability, supporting long-term design continuity.

Frequently Asked Questions (FAQ)

Q: Can the LEA-M8T-1 directly replace the LEA-6T-1 in existing designs?

A: The LEA-M8T-1 maintains identical supply voltage (2.7V ~ 3.6V), package format (28-SMD Module), and I2C/UART/USB interface support. Operating temperature range remains -40°C to 85°C. Designs utilizing these interfaces and temperature specifications require no modification. Designs dependent on GPS-only protocol operation must evaluate multi-constellation support implications.

Q: What is the primary difference between LEA-M8T-1 and LEA-F9T-10B?

A: The LEA-M8T-1 includes I2C interface support and operates to 85°C maximum. The LEA-F9T-10B omits I2C but extends maximum operating temperature to 105°C and includes a band pass filter. Interface requirements and thermal specifications determine appropriate selection.

Q: Are both substitute parts compatible with existing PCB layouts designed for LEA-6T-1?

A: Both LEA-M8T-1 and LEA-F9T-10B use identical 28-SMD Module packaging. Physical footprint compatibility is confirmed. Electrical interface verification is required based on specific design implementation of I2C, UART, and USB signal routing.

Q: Do the substitute parts maintain the same regulatory compliance?

A: Both LEA-M8T-1 and LEA-F9T-10B are ROHS3 compliant and REACH unaffected, matching the LEA-6T-1 regulatory status. ECCN and HTSUS classifications are provided for export and tariff documentation.
