Parameter Comparison

Engineering Selection Recommendations

The MTSMC-L4N1-U.R3-SP is the manufacturer-recommended substitute for the MTSMC-L4N1-U.R1A-SP. Selection of the substitute part is justified on the following engineering grounds:

Product Status Alignment: The MTSMC-L4N1-U.R3-SP carries an "Active" product status, ensuring continued manufacturer support, availability, and compliance updates. The original part's "Not For New Designs" designation indicates end-of-life trajectory and reduced long-term availability.

Functional Compatibility: Both modules operate within identical frequency bands, voltage supply ranges, and temperature specifications. The 150Mbps data rate is maintained across both parts, ensuring equivalent throughput performance.

Enhanced Interface Capability: The substitute part adds UART serial interface support while retaining USB connectivity. This expansion of serial interface options provides greater design flexibility without compromising existing USB-based implementations.

Compliance Status: The main part is confirmed ROHS3 compliant and REACH unaffected. Compliance specifications for the substitute part were not provided in the input data; however, the substitute's active product status indicates current regulatory alignment with industry standards.

Mechanical Compatibility: Both modules utilize identical U.FL antenna connectors, through-hole mounting configuration, and module-based packaging, ensuring direct mechanical substitution in existing PCB layouts.

Frequently Asked Questions (FAQ)

Q: Can the MTSMC-L4N1-U.R3-SP be used as a direct replacement for the MTSMC-L4N1-U.R1A-SP in existing designs?

A: Yes. Both modules operate across identical frequency bands (600MHz, 700MHz, 850MHz, 1.7GHz, 1.9GHz), maintain the same voltage supply range (3.3V ~ 5V), and share identical operating temperature specifications (-40°C ~ 85°C). The U.FL antenna connector and through-hole mounting are identical between both parts. The substitute part adds UART interface capability while retaining USB connectivity, making it functionally compatible with existing USB-based implementations.

Q: What is the difference in protocol support between these two modules?

A: The MTSMC-L4N1-U.R1A-SP supports 4G LTE CAT-4 (AT&T/Verizon-Mobile) and GNSS protocols. The MTSMC-L4N1-U.R3-SP supports GNSS, GPS, and LTE protocols. The substitute part adds explicit GPS support alongside GNSS capability and removes the specific AT&T/Verizon-Mobile designation, indicating broader LTE compatibility.

Q: Are there differences in serial interface connectivity?

A: Yes. The MTSMC-L4N1-U.R1A-SP provides USB serial interface only. The MTSMC-L4N1-U.R3-SP provides both UART and USB serial interfaces.
