Key Parameters

Substitute Part Grouping Explanation

Substitution of the MTSMC-LVW3.R2 is based on the following critical parameters:

Core Compatibility Criteria:

• Manufacturer: Multi-Tech Systems Inc. (same manufacturer ensures firmware and protocol compatibility)
• Series: SocketModem® Cell (maintains software and hardware interface consistency)
• Mounting Type: Through Hole (ensures mechanical compatibility with existing PCB layouts)
• Antenna Connector: U.FL (maintains antenna interface compatibility)
• Serial Interface: UART (preserves communication protocol with host systems)
• Operating Temperature Range: -40°C ~ 85°C (maintains thermal operating envelope)
• Voltage Supply Range: Must accommodate 3.3V ~ 5V operation

Frequency Band Compatibility: The substitute part must support the frequency bands required by the original application. The MTSMC-LVW3.R2 operates on 700MHz, 1.7GHz, and 1.9GHz. Substitute parts must support these bands as a minimum subset.

Product Status Consideration: The MTSMC-LVW3.R2 is obsolete. The MTSMC-L1G2D is classified as active, ensuring long-term availability and supply chain continuity.

Parameter Comparison

Engineering Selection Recommendations

The MTSMC-L1G2D is the manufacturer-recommended substitute for the obsolete MTSMC-LVW3.R2. Selection of this substitute is justified on the following engineering grounds:

Compliance and Regulatory Status: Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory continuity in applications subject to environmental directives.

Supply Chain Continuity: The MTSMC-L1G2D holds active product status with 878 units in stock, compared to the obsolete MTSMC-LVW3.R2. This ensures long-term availability for production and support applications.

Functional Compatibility: The substitute part maintains the same SocketModem® Cell series architecture, UART serial interface, U.FL antenna connector, through-hole mounting, and identical operating temperature range. These parameters ensure mechanical and electrical compatibility with existing designs.

Frequency Band Coverage: The MTSMC-L1G2D supports all frequency bands of the original part (700MHz, 1.7GHz, 1.9GHz) plus additional bands (800MHz, 850MHz, 900MHz, 1.8GHz, 2.1GHz, 2.6GHz), providing expanded network compatibility without sacrificing original functionality.

Voltage Supply Consideration: The MTSMC-LVW3.R2 operates at 3.3V ~ 5V, while the MTSMC-L1G2D operates at 5V. Systems designed for 3.3V operation require voltage regulation or level shifting to accommodate the substitute part.

Frequently Asked Questions (FAQ)

Q: Can the MTSMC-L1G2D directly replace the MTSMC-LVW3.R2 in existing designs?

A: Direct replacement is possible for systems operating at 5V supply voltage. Systems designed for 3.3V operation require additional voltage regulation circuitry. The mechanical footprint and electrical interfaces (UART, U.FL antenna) are compatible.

Q: What are the key differences between these two modules?

A: The primary differences are product status (obsolete vs. active), voltage supply specification (3.3V ~ 5V vs. 5V), supported frequency bands (3 bands vs. 9 bands), and serial interface options (UART only vs. UART and USB). The MTSMC-L1G2D adds GNSS and GPS protocol support.

Q: Does the MTSMC-L1G2D support the same Verizon 4G LTE CAT-1 bands as the original?

A: The MTSMC-L1G2D supports LTE protocol across a broader frequency range that includes the original 700MHz, 1.7GHz, and 1.9GHz bands required for Verizon 4G LTE CAT-1 operation.

Q: Are there any package or form factor differences?

A: The MTSMC-LVW3.R2 is specified as a Module package, while the MTSMC-L1G2D is specified as a 64-DIP Module with 45 leads. Both use through-hole mounting and U.FL antenna connectors. Verify PCB layout compatibility before substitution.

Q: What is the impact of the additional USB interface on the MTSMC-L1G2D?

A: The MTSMC-L1G2D includes USB in addition to UART. Existing designs using only UART are unaffected. The USB interface provides an alternative communication path for applications requiring higher bandwidth or different host integration methods.

Q: Are both parts RoHS compliant?

A: Yes, both the MTSMC-LVW3.R2 and MTSMC-L1G2D are ROHS3 compliant and REACH unaffected, maintaining regulatory compliance for environmental directives.
