Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MTSMC-L4N1.R2-SP is determined by the following critical parameters:

Mechanical Compatibility:

• Package type: 64-DIP Module with 45 leads
• Mounting method: Through Hole
• Antenna connector: U.FL

Electrical Compatibility:

• Voltage supply range: 3.3V ~ 5V
• Operating temperature range: -40°C ~ 85°C
• Frequency band coverage: 600MHz, 700MHz, 850MHz, 1.7GHz, 1.9GHz
• Data rate: 150Mbps

Functional Requirements:

• RF family/standard: Cellular, Navigation
• Protocol support: 4G LTE CAT-4 (AT&T/Verizon-Mobile), GNSS

Regulatory Compliance:

A substitute part must maintain compatibility across all mechanical parameters, support the same frequency bands and voltage specifications, and provide equivalent or enhanced protocol support. The substitute part must also maintain or exceed the regulatory compliance status of the original component.

Parameter Comparison

Engineering Selection Recommendations

The MTSMC-L4N1.R3-SP is the direct substitute for the MTSMC-L4N1.R2-SP based on the following engineering criteria:

Mechanical Compatibility: Both modules share identical package specifications (64-DIP Module, 45 Leads), mounting type (Through Hole), and antenna connector type (U.FL). Direct physical substitution is supported without PCB redesign.

Electrical Compatibility: Both modules operate within the same voltage supply range (3.3V ~ 5V) and temperature range (-40°C ~ 85°C). Current consumption specifications are not provided for the substitute part; however, the identical data rate (150Mbps) and frequency band coverage indicate equivalent power characteristics.

Functional Compatibility: Both modules support the same frequency bands (600MHz, 700MHz, 850MHz, 1.7GHz, 1.9GHz) and maintain cellular and navigation RF standards. The substitute part extends protocol support to include explicit GPS designation alongside GNSS and LTE, providing enhanced functionality.

Product Status and Support: The MTSMC-L4N1.R3-SP carries an "Active" product status designation, ensuring ongoing manufacturer support, availability, and access to firmware updates. The MTSMC-L4N1.R2-SP "Not For New Designs" status indicates discontinued active development.

Regulatory Compliance: Both modules maintain RoHS3 compliance and REACH unaffected status, ensuring equivalent environmental and regulatory standing.

Interface Enhancement: The substitute part provides expanded serial interface options (UART, USB) compared to the main part (Serial), offering greater integration flexibility for host system communication.
