Key Parameters

Substitute Part Grouping Explanation

The MAX-M10S-00B qualifies as a functional equivalent to the LEA-6H-0 based on the following substitution criteria:

Electrical Compatibility:

• Identical voltage supply range: 2.7V ~ 3.6V
• Identical operating temperature range: -40°C ~ 85°C
• Enhanced sensitivity: -167dBm (improvement over -162dBm)
• Supported protocols include all LEA-6H-0 constellations (Galileo, GLONASS, GPS) plus additional BeiDou and GNSS support

Mechanical Compatibility:

• Surface mount technology maintained
• Module-based packaging format preserved
• Antenna connector configuration: Not Included (matching specification)

Functional Capability:

• Multi-constellation GNSS receiver architecture
• Data interfaces include I2C and UART (subset of LEA-6H-0 interfaces)
• Active product status ensures ongoing availability and support

Engineering Selection Recommendations

For New Designs: The MAX-M10S-00B is the designated u-blox manufacturer substitute for the obsolete LEA-6H-0. This part maintains electrical and thermal specifications while providing enhanced sensitivity (-167dBm versus -162dBm) and expanded constellation support (BeiDou addition). The active product status ensures long-term availability and technical support.

For Existing System Maintenance: The MAX-M10S-00B operates within identical voltage and temperature parameters, enabling direct functional replacement in systems currently using the LEA-6H-0. PCB layout modifications are required due to the 28-SMD to 18-SMD package transition. The reduced pin count (18-SMD versus 28-SMD) necessitates verification of interface requirements, as the MAX-M10S-00B provides I2C and UART interfaces while the LEA-6H-0 additionally supports SPI and USB.

Compliance Considerations: The MAX-M10S-00B carries ROHS3 compliance, REACH unaffected status, and defined ECCN/HTSUS classifications, supporting regulatory requirements for new product deployments.

Frequently Asked Questions (FAQ)

Q: Can the MAX-M10S-00B directly replace the LEA-6H-0 without PCB modifications?

A: No. While electrical specifications are compatible, the package transition from 28-SMD to 18-SMD requires PCB layout redesign. The reduced pin count also necessitates interface verification.

Q: What is the impact of the data interface difference between these parts?

A: The LEA-6H-0 supports I2C, SPI, UART, and USB interfaces. The MAX-M10S-00B provides I2C and UART. If your application requires SPI or USB communication, interface compatibility must be confirmed before substitution.

Q: Does the MAX-M10S-00B support all satellite constellations of the LEA-6H-0?

A: Yes. The MAX-M10S-00B supports Galileo, GLONASS, and GPS (all LEA-6H-0 constellations) plus additional BeiDou and GNSS protocols, providing expanded capability.

Q: Are the voltage supply and operating temperature ranges identical?

A: Yes. Both parts operate at 2.7V to 3.6V supply voltage and -40°C to 85°C temperature range, ensuring thermal and electrical compatibility.

Q: What is the significance of the sensitivity improvement from -162dBm to -167dBm?

A: The MAX-M10S-00B provides 5dBm improved sensitivity, enabling reception of weaker satellite signals and potentially improving acquisition time and performance in signal-limited environments.

Q: Is the antenna connector configuration the same?

A: Yes. Both the LEA-6H-0 and MAX-M10S-00B specify antenna connector as "Not Included," maintaining identical external antenna interface requirements.
