Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MTSMC-LVW3-U.R2 is determined by the following critical parameters:

Primary Substitution Criteria:

• RF Family/Standard: Cellular
• Antenna Type: U.FL Through Hole
• Mounting Type: Through Hole
• Operating Temperature Range: -40°C ~ 85°C
• Voltage Supply Compatibility: 3.3V ~ 5V range
• Serial Interface Support: UART and/or USB

Secondary Compatibility Factors:

• Protocol Support: 4G LTE CAT-1 (Verizon) or compatible cellular protocols
• Data Rate: 10Mbps minimum
• Package Classification: Module form factor

Two substitute parts meet these criteria: MTSMC-LVW3-U.R4 and MTSMC-L1G2D-U. Both maintain the SocketModem® Cell series designation, U.FL antenna interface, through-hole mounting, and compatible operating temperature specifications. The MTSMC-LVW3-U.R4 provides direct protocol compatibility with added GNSS capability, while the MTSMC-L1G2D-U extends frequency band coverage and navigation support.

Parameter Comparison

Engineering Selection Recommendations

MTSMC-LVW3-U.R4 Selection: This substitute maintains identical frequency band coverage (700MHz, 1.7GHz, 1.9GHz) and current specifications (104mA receive/transmit) as the MTSMC-LVW3-U.R2. The addition of GNSS capability provides extended functionality without compromising core 4G LTE CAT-1 (Verizon) performance. Both parts are classified as Obsolete and carry ROHS3 compliance. The primary design consideration is the reduction of serial interfaces from dual (UART, USB) to USB-only on the MTSMC-LVW3-U.R4. Systems requiring UART connectivity must evaluate this interface limitation.

MTSMC-L1G2D-U Selection: This substitute is the only Active product among the three options, providing long-term availability and supply chain stability. It supports extended frequency band coverage (700MHz through 2.6GHz) and includes GPS/GNSS functionality alongside LTE protocols. The voltage supply specification is fixed at 5V, requiring verification of system power architecture compatibility. Current consumption specifications are not provided for this part. The expanded frequency band support enables operation across additional cellular networks beyond the Verizon-specific CAT-1 bands of the original part.

Compliance Status: Both MTSMC-LVW3-U.R4 and MTSMC-L1G2D-U maintain the SocketModem® Cell series designation and through-hole U.FL antenna interface, ensuring mechanical and electrical compatibility with existing PCB designs. The MTSMC-LVW3-U.R4 carries explicit ROHS3 compliance matching the original part. The MTSMC-L1G2D-U RoHS status is not specified in available documentation.

Frequently Asked Questions (FAQ)

Q: Can the MTSMC-LVW3-U.R4 directly replace the MTSMC-LVW3-U.R2 in existing designs?

A: Direct replacement is possible with one design consideration: the MTSMC-LVW3-U.R4 supports USB serial interface only, while the MTSMC-LVW3-U.R2 provides both UART and USB. If the design uses UART communication exclusively, interface modification is required. Frequency bands, voltage supply range, current consumption, and mounting specifications are identical.

Q: What is the primary advantage of selecting the MTSMC-L1G2D-U?

A: The MTSMC-L1G2D-U is the only Active product in the substitute group, ensuring ongoing manufacturer support and supply availability. It provides extended frequency band coverage (nine bands versus three) and integrated GPS/GNSS functionality. The fixed 5V supply requirement must be verified against system power architecture.

Q: Are there package/case differences between the substitutes?

A: The MTSMC-LVW3-U.R2 is specified as a Module package. Both substitutes are specified as 64-DIP Module with 45 Leads. While both maintain through-hole mounting and U.FL antenna connectivity, the pinout and physical dimensions may differ. PCB layout verification is required before implementation.

Q: Which substitute is recommended for new designs?

A: The MTSMC-L1G2D-U is recommended for new designs due to its Active product status, extended frequency band support, and integrated navigation capability. The MTSMC-LVW3-U.R4 is suitable for legacy system maintenance where Verizon CAT-1 band-specific operation is required and UART interface is not essential.

Q: What are the voltage supply compatibility considerations?

A: The MTSMC-LVW3-U.R2 and MTSMC-LVW3-U.R4 both accept 3.3V to 5V supply voltage. The MTSMC-L1G2D-U requires a fixed 5V supply. Systems operating at 3.3V must use either of the first two options or implement voltage regulation for the MTSMC-L1G2D-U.

Q: Are current consumption specifications available for all substitutes?

A: The MTSMC-LVW3-U.R2 and MTSMC-LVW3-U.R4 specify 104mA for both receive and transmit operations. Current consumption data for the MTSMC-L1G2D-U is not provided in available documentation and must be obtained from the manufacturer for power budget calculations.
